Agenda Number: 2 Section Name: STUDY SESSION Account Number: 10-4661 File ID: 24-8502 TO: City Council
FROM: Alex Khojikian, City Manager
PREPARED BY: Public Works Department
MEETING DATE: April 15, 2024
SUBJECT:

Draft Local Roadway Safety Plan
RECOMMENDATION:

Receive a presentation on the draft Local Roadway Safety Plan and provide feedback.

BACKGROUND:

In August 2020, staff from the Police and Public Works Departments introduced the topic of addressing traffic safety with a data-driven approach to City Council, and shared preliminary data correlating staff’s efforts on neighborhood Traffic Action Plans to collision trends. Council supported applying funds and concentrating efforts where they would yield the greatest safety results. Staff brought additional data to Council in November 2020, which identified the challenges with vehicle-to- pedestrian collisions in the City. In June 2021, more detailed information regarding collision trends was presented, and Council directed staff to continue pursuing traffic safety project prioritization through completion of a Local Roadway Safety Plan (LRSP).

The City’s Local Roadway Safety Plan creates a data-driven and community-informed decision-making framework that will work toward the goal of eliminating fatal and severe injury collisions on local roadways. The LRSP uses historical collision data and an understanding of local context, while factoring in equity priority communities, to assess existing roadway safety conditions in San Mateo, identifies areas for improvement, and provides recommended actions and an implementation plan that will help create a Safe System (an approach to roadway safety adopted by the United States Department of Transportation and Caltrans) and culture of roadway safety in the City of San Mateo. Additionally, having an approved LRSP qualifies the City for certain types of grant funding, such as the Highway Safety Improvement Program (HSIP) and Safe Streets for All (SS4A) grant programs.

The LRSP is organized into five sections:

1.Vision, Mission, and Goals – Establishes a larger vision for transportation safety in San Mateo and sets goals for how to get there.

2.Plan Development Process – Details the collaborative data-driven and community-informed planning process.

3.Existing Safety Conditions – Provides an analysis of collisions in San Mateo.

4.Emphasis Areas, Countermeasures, and Strategies – Details the emphasis areas and lists proven countermeasures and strategies that can improve roadway safety.

5.Recommendations, Actions, and Implementation – Proposes short- and long-term projects and sets a city-wide strategy for assessing progress toward established goals.

The LRSP includes recommended systemic treatments to generally improve roadway safety in the City. Following the presentation, staff will request feedback from Council on how to prioritize implementation of the proposed systemic

CITY OF SAN MATEO
treatments (improvements that can be made proactively at locations that do not have collision data trends but have similar characteristics to locations that do) with a focus on their impact city-wide, rather than any specific location.

Sustainability and Infrastructure Commission Feedback
Staff gave an informational presentation to the Sustainability and Infrastructure Commission (SIC) in July 2023 on initial LRSP development efforts, including outlining collision analysis findings, the community outreach plan, and project timeline. Feedback provided during that meeting included ensuring project costs are transparent within the plan and a recommendation to include quick-build projects.

In March 2024, staff went back to SIC and presented the draft LRSP including information about recommended site- specific and systemic treatments, noted how they relate to the feedback on safety concerns received during community outreach, and requested feedback specifically regarding the proposed systemic treatments. The Commission generally supported the proposed systemic treatments and recommended consideration for exclusive pedestrian phasing at some signalized intersections. The Commission noted a lack of representation from community members with mobility challenges and requested the Project Development Team be expanded to include additional viewpoints. Lastly, programmatic and informational recommendations were requested to be incorporated that pertained to increased enforcement for vehicles parked in crosswalks as well as a recommendation for roadway users to wear high-visibility clothing. All feedback has been noted and incorporated where appropriate into the draft LRSP.

Feedback and Next Steps
The project team will present the draft LRSP, including information about how this plan relates to a future Vision Zero Plan.

Staff will share information about the proposed systemic safety improvements and solicit feedback from Council on how to prioritize their implementation on a city-wide basis.

Following the meeting, the project team will incorporate Council feedback and bring the Local Roadway Safety Plan for adoption thereafter, tentatively in May.

BUDGET IMPACT:

There are no budget impacts for receiving an informational presentation about the Local Roadway Safety Plan. The project is funded through Caltrans grant funds, matching funds from the Citywide Traffic Calming project (466600) and supplementing funds from the Neighborhood Traffic Management project (462226).

ENVIRONMENTAL DETERMINATION:

This informational update is not a project subject to CEQA, because it is an organizational or administrative activity that will not result in direct or indirect physical changes in the environment. (CEQA Guidelines Section 15378(b)(5).)

1 INTRODUCTION
The City of San Mateo is located about 20 miles south of San Francisco and borders Burlingame to the north, Hillsborough to the west, San Francisco Bay and Foster City to the east, and Belmont to the south. The City’s population, at the 2022 Census, was 10 0,9841. The City of San Mateo’s roadways see an average of one fatality and 1 6 severe injuries annually in the past five years . Despite an overall reduction in total collisions during the pandemic, the frequency of fatal and severe injury collisions has increased. Additionally, severe injuries involving people walking, biking, and rolling have tripled in the last five years.2 The City has a total of 418 lane miles of roadways, including freeways and state routes, according to Metropolitan Transportation Commission’s standards3.

The City of San Mateo (City) is committed to eliminating fatal and severe injury collisions on its roadways. To advance this mission, the City developed a Local Roadway Safety Plan (LRSP), which establishes a framework to help San Mateo residents and visitors travel safely through the city to their destinations.

The City of San Mateo’s Local Roadway Safety Plan (LRSP) is a living document designed to be updated to respond to evolving community needs . The City of San Mateo is diverse i n terms of land use context, comprising of urban and suburban neighborhoods, as well as a multilingual population. Additionally, the City’s growing economy and the presence of several major state-owned highways require the City to balance both the local and regional travel needs. Given these factors, this LRSP will be revisited and updated approximately every five years, to account for changes in travel patterns and road user behavior .

Additionally, the Action Items and Performance Measures identified in the LRSP should be tracked annually to assess progress towards achieving the LRSP’s Vision, Mission, and Goals.

1.1 What is an LRSP?
The purpose of an LRSP is to assess the safety of a city's roadways , identify areas that need improvement, and recommend engineering countermeasures and strategies to address those identified issues . The LRSP provides a range of strategies to address safety concerns, from engineering countermeasures to educational campaigns and emerging technology related strategies. The safety plan also provides a timeline and goals for implementation and evaluation. The approach is multi -disciplinary, meaning that stakeho lders from different agencies and organizations will need to work together to implement the recommended countermeasures, strategies, and overall vision for the plan. This includes law enforcement, fire department, neighboring jurisdictions, public health services, emergency response providers, community organizations, and the broader community.

LRSPs are recognized as a proven safety countermeasure by the Federal Highway Administration (FHWA).

They prioritize investments and assist with the implementation of engineering strategies. Two Federal funding programs, the Highway Safety Improvement Program (HSIP) and Safe Streets and Roads for All (SS4A), provide funding for the implementation of countermeasures that address road safety challenges on public roads. In California, to pursue HSIP grant funds through Caltrans’ grant program, a local agency must have an LRSP or an equivalent planning document. To pursue federal SS4A funding, a local agency must have a safety action plan that is equivalent to an LRSP, provided certain implementation frameworks are included that associate actions with timing, funding, and leads. In addition to these federal funding program s, the Active Transportation Program (ATP), managed by California Transportation Commission (CTC) consolidates federal and state transportation programs to encourage increased use of active transportation modes and ensure that disadvantaged communities fully share in the benefits of the program. Access to these funds can help

the City to fund engineering - and non -engineering-related solutions that can make its roads safer for everyone.

1.1.1 Aligning with the California Strategic Highway Safety Plan LRSPs across the state complement the 2020-2024 California Strategic Highway Safety Plan (SHSP), providing intentional and continual assessment and improvements to enhance roadway safety. The SHSP sets out California’s vision, goals, and objectives for reducing fatal and severe injury collisions on public roadways (local roadways and state highways).4 The California Department of Transportation (Caltrans) leads ongoing efforts to analyze collision data and collaborate with traffic safety partners across the entire state to identify these focus areas and continually monitor and identify actions to address these focus areas . The SHSP identifies key safety needs and guides investment decisions toward strategies and countermeasures with the most potential to save lives and prevent injuries.

The SHSP identified California’s 16 Challenge Areas, or areas that should be the focus for roadway safety in California. As discussed in greater detail in the Statewide Comparison discussion in Section 4: Existing Safety Conditions, the three items bolded on this list were identified as high priority challenge areas for San Mateo, meaning improvements in these areas have the greatest opportunity to reduce death and severe injury.

1.1.1.1.1 SHSP Challenge Areas
◼ Pedestrians
◼ Bicyclists
◼ Aging Drivers
◼ Commercial Vehicles
◼ Distracted Driving
◼ Driver Licensing
◼ Emergency Response
◼ Emerging Technologies
◼ Impaired Driving
◼ Intersections
◼ Lane Departures
◼ Motorcyclists
◼ Occupant Protection
◼ Speed Management / Aggressive Driving
◼ Work Zones
◼ Young Drivers
Historically, the SHSP has used the five E’s (Education, Enforcement, Engineering, Emergency Response, and Emerging Technologies) to organize strategies. In 2021, state transportation officials shifted focus and adopted guiding principles that integrate social equity, utilize the Safe System Approach, and encourage the use of proven countermeasures and emerging technologies.

1.1.2 Incorporating the Safe System Approach
In January 2022, the United States Department of Transportation (USDOT) released its National Roadway Safety Strategy that adopted the Safe System Approach as its core strategy5.

There are five elements (or layers) to a Safe System (see Figure 1):
◼ Safe Roadway Users – All roadway users, including bicyclists, pedestrians, and transit riders, should be able to travel safely.
◼ Safe Vehicles – Vehicles should be designed and regulated to reduce the frequency and severity of collisions.
◼ Safe Speeds – The faster a vehicle is traveling, the greater its risk to human life. Safe speeds are speeds that reduce impact forces, improve stopping time, and improve visibility. ◼ Safe Roadways – Roadway design can accommodate human mistakes and improve injury tolerances through strategies, such as physically separating those traveling at different speeds or using signage to alert drivers to hazards.

◼ Post-Collision Care – If a collision does occur, first responders must assess, stabilize, and transport those who were injured. Forensic investigation or incident management teams are also important parts of post-collision care.

Figure 1: FHWA’s Safe System Elements

1.1.2.1 San Mateo and the Safe Systems Approach
This LRSP uses the Safe System Approach to identify ways that San Mateo and its safety partners can create layers to help protect all roadway users – even when they make mistakes. The City is the driving force behind implementing engineering -related safety measures such as speed management or roadway design.

Commitment from City staff and road safety partners to prioritize safety in their efforts and to implement both proven and innovative ideas are key to advancing road safety and for the LRSP to be impact ful. The Safe System Approach considers all road users and identifies potential conflicts, as well as locations where proactive safety treatments can be implemented. Collaboration among all stakeholders, including road users, transportation system managers, law enforcement, emergency responders, and vehicle manufacturers, is crucial for achieving its goal of eliminating fatal and severe injuries.

To build redundancy in the local transportation system, San Mateo and its teaming partners can:
◼ Establish and continue to revisit vision, goals, and partnerships to help implement the LRSP. ◼ Identify systemic and location -specific engineering countermeasures and use them proactively and reactively.
◼ Provide education programs and overlap stakeholder efforts to communicate key roadway safety information to residents, business owners, and schools and create a culture of roadway safety. ◼ Review and revisit policies, guidelines, and standards to prioritize roadway safety in the City.

◼ Identify potential funding sources for project implementation, including quick-build projects.

This LRSP and its recommendations can help create a Safe System and culture of roadway safety in the City of San Mateo. However, state and federal policies, such as legislation for automated speed enforcement and continued regulation of vehicle safety stan dards will be essential to complete the Safe System categories that the City and local agencies cannot directly affect.

1.2 Plan Overview
This LRSP uses historical collision data and an understanding of local context to assess existing roadway safety conditions in San Mateo , identify areas for improvement, and provide recommended actions and an implementation plan. Ultimately, this LRSP creates a data -driven and community-informed decision-making framework to reduce the number of fatal and severe injury collisions on local roadways.

The plan is organized into five main sections:

1. Vision, Mission, and Goals – Establishes a larger vision for transportation safety in San Mateo and sets goals for how to get there.

2. Plan Development Process – Details the collaborative data-driven and community-informed planning process.

3. Existing Safety Conditions – Provides an analysis of collisions in San Mateo.

4. Emphasis Areas, Countermeasures, and Strategies – Details the emphasis areas and lists proven countermeasures and strategies that can improve roadway safety.

5. Recommendations, Actions, and Implementation – Prioritizes short- and long-term projects and sets a strategy for assessing progress toward established goals.

2 VISION, MISSION, AND GOALS
The Vision, Mission, and Goals of the LRSP were created collaboratively by representatives from the City and the Project Development Team (PDT) and covers both short- and long-term outcomes. The City of San Mateo is committed to implementing the FHWA's Safe System Approach in its future efforts related to road safety, to achieve its goals. Although the City's road network is extensive and intricate, ongoing, and anticipated safety initiatives are designed to gradually reduce the risk of accidents on the City's roads.

2.1 Vision
The City of San Mateo envisions a roadway network that prioritizes safety for all users, ensuring secure travel throughout the city.

2.2 Mission Statement
The City of San Mateo will use a collaborative, data-driven, and community-informed approach to proactively identify and address collision risk factors to implement safety countermeasures, strategies, and programs that can ultimately eliminate preventable fatalities and severe injuries within the City.

The City of San Mateo is committed to using data and Safe System principles recommended by FHWA and the California SHSP to assess road safety to prevent collisions proactively and systemically across the entire roadway network. The City is committed to reaching its goal of eliminating all preventable traffic fatalities and severe injuries by 2050.

2.3 Overarching Goals
The following goals will guide collaborative planning efforts with the PDT and other safety related partners:
◼ Use a data -driven and community -informed approach to identify priority locations for safety improvements.
◼ Implement proactive approaches to improve roadway safety and i dentify cost -effective systemic countermeasures.
◼ Prioritize investments in countermeasures and strategies that reduce collisions in identified emphasis areas.
◼ Collaborate with agencies and safety partners towards implementation. ◼ Educate and promote safe travel practices in the City of San Mateo. ◼ Periodically monitor and evaluate collision reduction goals with respect to emphasis areas and overall safety performance of the City's transportation network.

Plan Development Process

23 of 337

April 2, 2024 San Mateo Local Roadway Safety Plan Kittelson & Associates, Inc. Page 15

3 PLAN DEVELOPMENT PROCESS
This LRSP was developed according to the guidelines and requirements set forth by Caltrans and followed the FHWA's Developing Safety Plans manual and the Safe System Approach. The FHWA's LRSP development process is captured in Figure 2, and consists of four main steps:

1. Establishing stakeholders

2. Using safety data (analyzing safety data and identifying collision types and high -collision risk locations)

3. Choosing proven solutions

4. Implementing solutions
The first step of the plan involved bringing together a diverse group of stakeholders, the Project Development Team (PDT), to provide input on roadway safety issues and identify needs. Subsequently, the City analyzed available roadway and collision data to understand collision patterns, risk factors, and areas for improving safety. However, since data can be incomplete or inaccurate, the LRSP used a community-informed approach that combined data analysis with input from the community and the PDT to provide a more comprehensive understanding of transportation safety issues. Based on this analysis, a selection of proven countermeasures was identified to form a countermeasure toolbox and guide the implementation plan for the LRSP.

April 2, 2024 San Mateo Local Roadway Safety Plan Kittelson & Associates, Inc. Page 16

The following two stakeholder groups have been valued partners that represent a unique set of experiences, needs, and views on roadway safety in the City of San Mateo.

3.1 Project Development Team (PDT)
The PDT was developed to include representatives from a broad cross section of community, business, educational, and government interests. Each person represents a unique set of experiences and perspectives on the transportation system in San Mateo that helped shape the LRSP . The following departments and organizations were represented in the PDT:
◼ San Mateo Consolidated Fire Department
◼ San Mateo County Office of Education
◼ San Mateo County Health
◼ City of San Mateo Senior Citizens Commission
◼ San Mateo Police Department
◼ City of San Mateo Age-Friendly Implementation Committee ◼ Center for Independence of Individuals with Disabilities, serving San Mateo County

3.1.1 Meeting Dates and Topics
The PDT met twice over the course of the LRSP’s development, discussing topics as summarized below:

3.1.1.1 Meeting 1|June 26, 2023
 Define LRSP purpose and scope.
 Present and gather feedback on preliminary data analysis.  Present network screening results.
 Discuss potential emphasis areas based on data findings.

During the meeting, the PDT members requested the project team to refer to the High Injury Network (HIN) created by the Safe Routes to School (SRTS) team for identifying priority locations near San Mateo Schools, as applicable. Furthermore, the project team was advised to consider specific collision data related to vehicle types, collision trends, and develop maps detailing pedestrian and bicycle-specific collisions in the LRSP. Lastly, the PDT encouraged the project team to look at the City’s older populations’ origins and destinations to better understand and evaluate the sidewalk network within these regions.

For development of the countermeasure toolbox in the LRSP, the PDT members suggested including the following measures currently being installed near schools:
 Curb extensions
 Mini traffic circle
 High visibility crosswalks
 Rectangular rapid flashing beacons (RRFBs)

3.1.1.2 Meeting 2|January 17, 2024
 Discuss community engagement activity and reach.
 Discuss actions and performance measures.
 Review Draft LRSP recommendations.
 Discuss implementation and responsibilities.

One of the PDT members noted that the crosswalk at the intersection of 3rd Avenue/El Camino Real is slippery. The PDT members suggested tracking drivers running a red light and recommending installing stop

25 of 337

April 2, 2024 San Mateo Local Roadway Safety Plan Kittelson & Associates, Inc. Page 17

signs or plaques indicating intersections are not all-way stop controlled, specifically at two-way stop- controlled intersections.

One of the PDT members noted that the Pedestrian Hybrid Beacons (PHB’s) are helpful for individuals with disabilities as they are mounted overhead rather than on the side of the roadway. They also noted that consideration is needed at high-traffic locations to make sure that the pedestrians in wheelchairs are visible and are in the driver’s line of sight. This PDT member also noted the consideration of pedestrian and bicycle improvements on Pacific Boulevard from Hillsdale Boulevard to south City limits and at the 25th Avenue/Flores Street intersection. These two locations were not part of the Tier 1 locations identified in this LRSP (noted in Section 4.3.2 Safety Performance Network Screening). As a result, they were neither specifically evaluated nor any countermeasures were recommended in this study.

3.2 Sustainability and Infrastructure Commission (SIC)
The SIC is an advisory body to the City Council, established to advise on policies and programs related to environmental sustainability, transportation and infrastructure. Each committee member represents a unique set of experiences, needs, and views of the transportation system and roadway safety in the City of San Mateo that helped shape the LRSP. Continuing to leverage City relationships with the SIC will help in identifying proactive safety strategies , countermeasures at high -risk locations , and adminis tering or promoting programs that encourage safe transportation behaviors.

Similar to the PDT, the SIC met twice over the course of the LRSP’s development, discussing the same topics as summarized above. The SIC meetings took place on July 12, 2023 and March 13, 2024. Copies of the SIC presentations are included in Appendix A. The SIC meetings were also open to the community.

During the first meeting, the SIC commented that the outreach should be transparent about the costs of implementing the safety improvements. The SIC members were also concerned about the intersection of Hillsdale Boulevard and Saratoga Drive which currently lacks a marked crosswalk on the eastbound leg of the intersection. Furthermore, the SIC suggested that the project team consider quick-build improvements6.

During the second meeting, the SIC commented that representation from individuals with disabilities committee would be helpful to understand their perspective on LRSP. One of the SIC members noted that there are three intersections on Santa Inez Avenue that are identified in the Tier 2 priority intersections list and that more explanation is needed in the LRSP on how Tier 1 and Tier 2 intersections are designated.

6 Quick-Build projects require minor construction activities but are built with durable, low to moderate cost materials, and last from one year to five years. These projects have moderate design flexibility to anticipate some adjustments that may occur. The purpose of a Quick -Build project is to immediately implement safety needs, all owing a community to benefit quickly from improvements made, and allowing the people of a community affected by the project to provide input and test the project improvements before they are permanently constructed.

April 2, 2024 San Mateo Local Roadway Safety Plan Kittelson & Associates, Inc. Page 19

4 EXISTING SAFETY CONDITIONS
The existing safety conditions are determined by reviewing relevant regional and local planning documents, community engagement, and collision analysis. Prior to engaging with the community, the project team developed a community outreach and engagement strategy that incorporated an equity analysis to identify underserved and disadvantaged communities. The engagement strategy was r evised periodically as the LRSP progressed to ensure effective and meaningful engagement. The outcome from the existing conditions informed the emphasis areas and priority locations.

4.1 Existing Safety Practice and Culture
This section summarizes the regional and local planning documents pertaining to local roadway safety in San Mateo. Additionally, a summary is included to show the relevance of the document in the development of LRSP. The complete synthesis of roadway safety-related documents for the City of San Mateo and adjacent jurisdictions is included in Appendix B.

4.1.1 MTC Regional Safety/Vision Zero Policy (2020)
The MTC Regional Safety/Vision Zero Policy establishes a strategy for working with partner agencies to support equitable and data-driven action towards eliminating traffic deaths and serious vehicular injuries in the Bay Area by 2030.

Relevance to the LRSP development
◼ Establishes regional vision for collaborative and data -driven approach to eliminate traffic deaths and serious injuries.
◼ Emphasizes equity in roadway safety management planning and implementation.

4.1.2 C/CAG of San Mateo County Safe Routes to School Reports (2017)
In 2010, the C/CAG partnered with the San Mateo County Office of Education (SMCOE) to develop and implement the San Mateo County Safe Routes to School program to the 25 school districts in San Mateo County, in which elementary schools and middle schools in the City of San Ma teo are affiliated with San Mateo-Foster City Elementary School District, and high schools in the City are affiliated with San Mateo Union High School District. The goal of the program was to improve the health, well -being, and safety of children by encouraging and enabling them to walk and bike to school.

Relevance to the LRSP development
◼ Opportunity for collaboration across agencies to create safe routes for students and integrate strategies across the LRSP and Safe Routes to School program. ◼ Identifies a toolbox of potential improvements for school-specific concerns and risks. ◼ Surveys include community -perceived barriers to walking and biking to school, which could inform development of targeted countermeasures for the LRSP.

4.1.3 San Mateo County Safe Routes to School High Injury Network Report (2022)
The High Injury Network (HIN) report details the process and outcomes of a youth-based HIN analysis. The HIN identifies segments in a roadway network where many pedestrian and bicycle collisions have occurred, prioritizing those with greater severity and those involving youth or active -mode victims. HIN synthesizes

28 of 337

April 2, 2024 San Mateo Local Roadway Safety Plan Kittelson & Associates, Inc. Page 20

information about collision characteristics, collision patterns, and user types to identify roadway segments that account for the highest number of specific types of collisions.

Relevance to the LRSP development
◼ Opportunity to use HIN to identify segments near schools where students traveling to or from school may face increased safety challenges.

4.1.4 Transit-Oriented Development (TOD) Pedestrian Access Plan (2022)
The San Mateo Transit -Oriented Development Pedestrian Access Plan serve s as a roadmap to enhance pedestrian safety and create comfortable walking routes to transit for all ages and abilities. The scope of the Plan includes the pedestrian path of travel within a half-mile radius of the City's three Caltrain stations and along El Camino Real to account for frequent SamTrans service along this corridor. Caltrain and SamTrans have created new visions for their service in San Mateo County and this plan aims to complement these visions by making it easy to access transit for existing and future residents, employees, and visitors.

Relevance to the LRSP development
◼ Identifies issues informed by the community related to pedestrian access to transit. ◼ Provides examples and takeaways from community engagement which informed the LRSP’s community engagement activities and safety recommendations.

4.1.5 San Mateo Bicycle Master Plan (2020)
The 2020 San Mateo Bicycle Master Plan is the culmination of over a year of robust community engagement, data analysis, planning, and design work. This Plan is an update of the City’s 2011 Bicycle Master Plan and serves as a blueprint for expanding and improving the San Mateo bicycle and mobility network in the coming years.

Relevance to the LRSP development
◼ Establishes goal to reduce bicycle-related crashes, injuries, and fatalities. ◼ Identifies bicyclist safety-related concerns and hotspots. ◼ Proposes bicycle facilities and intersection improvements that would enhance safety and comfort of bicyclists.

4.1.6 San Mateo Citywide Pedestrian Master Plan (2012)
The Citywide Pedestrian Master Plan is a blueprint for the City of San Mateo to improve the pedestrian environment, secure funds dedicated to pedestrian safety and livable communities, and increase the number of walking trips. The Plan provides a broad vision, strategies, and actions for improving the pedestrian environment in the city. Safety is identified as one of the six goals of the Plan. Specifically, the City sought to reduce the number of pedestrian related crashes, injuries and fatalities by 50 per cent from 2010 levels by 2020.

Relevance to the LRSP development
◼ Establishes goal to reduce pedestrian-related crashes, injuries, and fatalities. ◼ Identifies pedestrian safety-related concerns and hotspots. ◼ Integrates existing regulations and best practices into a set of pedestrian enhancements that can enhance the safety, convenience, and mobility for pedestrians in the City which was coordinated with the LRSP recommendations.

4.1.7 San Mateo 2030 General Plan (2010)
The San Mateo’s General Plan is the community’s planning guide that defines the long -term vision and provides the framework for all zoning and land use decisions within the community. The General Plan seeks to establish a balance between the need for new g rowth and development and the preservation of the City’s high quality of life. At the time of writing this LRSP, t he City is working on updating the General Plan 2040, which will likely be adopted in March 2024. More information on this General Plan 2040 can be found at www.cityofsanmateo.org/1537/General-Plan.

The Strive San Mateo General Plan 2040 includes ten big ideas that will guide the next 20 years of San Mateo.

These Big Ideas are a mix of enduring principles that have guided decision -making in San Mateo for many years and support the City’s history and fabric while introducing new concepts and topics that reflect present-day concerns and challenges. The ideas are as follows:

1. Balance growth and change,

2. Enhance San Mateo’s neighborhood fabric and quality of life,

3. Preserve nature as the foundation of the city,

4. Encourage all ways to travel around the city,

5. Support the local economy,

6. Address historic preservation holistically,

7. Initiate a comprehensive sea level rise strategy,

8. Strengthen community outreach,

9. Focus on equity and health for all residents, and,

10. Improve community safety planning and awareness.

This General Plan 2040 recognizes the importance of improving the safety of the multimodal transportation network and includes a Vision Zero policy. Vision Zero is based on the five elements of a Safe Systems Approach advanced by the FHWA to eliminate traffic fatalities and serious injuries on roadways – the components and elements of the Safe System Approach is explained in detail in Section 1.1.2 Incorporating the Safe System Approach.

The General Plan also notes an action related to the Vision Zero Plan, as follows:

Action C 1.12 Vision Zero Plan: Complete and regularly update a plan that uses a safe systems approach to work towards Vision Zero and identifies specific citywide changes to policies, practices, funding, and other action items that will reduce speeding, collisions, and collision severity.

Relevance to the LRSP development
◼ Citywide safety-related goals and policies were considered in the LRSP. ◼ Coordination of long-term citywide improvements with LRSP recommendations and strategies.

4.1.8 Age Friendly San Mateo Three-Year Action Plan 2022-2025 The Age-Friendly Task force used public data to identify likely walking routes for older adults and partnered with the City Public Works Department to encourage prioritization of sidewalk repairs and minimizing safety hazards on those routes to reduce liability risk and encourage walking by seniors for health and socialization.

These results were also shared with the San Mateo Police Department to assist with enforcement of rules regarding parking that obstructs sidewalks.

Relevance to the LRSP development
◼ Identifies likely walking routes for older adults and locations for prioritizing sidewalk repairs.

4.2 Engagement and Outreach
As part of this LRSP, a series of public engagement activities were organized to gain insights on safety issues and needs from the community. These activities were tailored towards the unique character of the City of San Mateo and informed by discussions with City staff. Focused neighborhoods for community engagement were determined based on the results from collision analysis and equity analysis.

A comprehensive collision database was developed using the reported collision data from January 1, 2017, through December 31, 2021. Collision analysis revealed collision types, primary collision factors, and intersections and segments that have the highest collision frequency and severity. More information on collision analysis is described in Section 4.3 Citywide Safety Performance Analysis.

4.2.1 Equity Analysis
Equity is a fundamental consideration of the Safe System Approach, particularly given that pedestrian and bicyclist fatality rates on a per-capita basis vary largely by race,7 as well as by income, age, and gender to varying degrees in varying places.8 These outcomes underscore the need to explicitly examine correlations between sociodemographic and risk factors related to roadway infrastructure and operations.

To inform the communities in the City that are or have been historically underserved, Kittelson conducted the following evaluation:
◼ Demographic analysis
◼ Metropolitan Transportation Commission’s (MTC) Equity Priority Communities (EPC) ◼ State of California’s Disadvantaged Communities
◼ Transportation Disadvantaged Population Index
◼ SS4A Underserved Communities Census Tracts (Historically Disadvantaged Communities and Areas of Persistent Poverty)

4.2.1.1 Demographic Analysis
The City of San Mateo has a population of 104,333 according to the American Community Survey (ACS) 2019 5-year estimates. The working age population cohort (ages 20 to 64) represents the largest population segment in the City at more than 60 percent of the total population. San Mateo residents are highly educated, with nearly half (48 percent) of people aged 25 years or older holding at least a bachelor’s degree. Table 1 shows the racial composition of the City.

Asian and Pacific Island languages constitute about 16 percent of the population, of which 39 percent do not speak English very well.

4.2.1.2 Equity Priority Communities
Formerly called “Communities of Concern,” EPCs are Census tracts that have a significant concentration of underserved populations, such as households with low income and people of color. A combination of additional factors helps define these areas, including Limited English proficiency households, seniors 75 years and older, zero -vehicle households, single parent households, people with a disability, and rent -burdened

32 of 337

April 2, 2024 San Mateo Local Roadway Safety Plan Kittelson & Associates, Inc. Page 24

households. The EPCs were updated in 2021 and use ACS 2018 5 -year estimates.9 Figure 3 shows the EPCs in the City of San Mateo.

Findings
◼ Areas of North Central, Shoreview and parts of Downtown San Mateo as EPCs. These areas are generally located between Delaware Street, Peninsula Avenue, 5th Avenue and Bay Trail.

4.2.1.3 State of California’s Disadvantaged Communities The Disadvantaged Communities (DAC) represent Census tracts that experience high levels of pollution and/or Census tracts that are federally recognized as tribal areas. The DAC designations were updated in 2022 to designate census tracts receiving the highest 25 percent of overall scores in CalEnvironScreen4.0 as disadvantaged.10 Figure 3 shows the CalEnviroScreen 4.0 top 25th percentile DAC extent in the City of San Mateo.

Findings
◼ Similar to the EPCs, DACs are also located in the North Central and Downtown San Mateo.

4.2.1.4 SS4A Underserved Communities Census Tracts
The SS4A program allocates grants to support local initiatives aimed at preventing roadway fatalities and severe injuries. In alignment with the Justice40 initiative, USDOT is actively working to tackle and rectify decades of inadequate investment in under served communities. Currently, 25 percent of the total population is in Disadvantaged Census Tracts in San Mateo.

Figure 4 shows SS4A underserved communities. 11
Findings
◼ Similar to the EPCs and DACs, North Central and Downtown neighborhood remain underserved communities with an addition of the Hillsdale neighborhood west of El Camino Real.

Collision analysis identified collision patterns, trends, and high-priority intersections and roadways, and equity analysis informed the historically underserved areas within the City , with potential issues related to specific collision types and severities. These two pieces of information were used to determine focused neighborhoods in the City that warranted extra attention during community engagement activities.

The overview of engagement strategies is provided below, detailed information related to each of these strategies and their reach can be found in Appendix C.

4.2.2 Project Webpage
Kittelson collaborated closely with the City staff to create a project webpage 12, which was hosted on the City’s website. This dedicated webpage served as a one -stop shop for updates and information related to the LRSP. The webpage featured an array of valuable resources, including an overview of the LRSP, details on upcoming events, project updates, an interactive web map, a story map, and access to relevant documents.

4.2.2.1 Interactive Map
The interactive map was utilized to get location-specific feedback from communities throughout the city. A total of 507 comments were received between early June 2023 through September 2023 after Labor Day, September 8, 2023. Of the total comments, 57 percent (289) of the comments were in focused neighborhoods. Duplicate comments were removed during the revi ew. Figure 4 shows the location of comments by user-defined type.

4.2.2.2 Story Map
Kittelson completed data analysis of collision trends in the city and compiled examples of safety countermeasures (or improvements) that can address these collision related trends in the Story Map13. A Story Map is an interactive web -based tool that provides information on the overview of LRSP, citywide collision patterns and trends, preliminary data analysis findings, countermeasures list, and a link directing users to interactive map, shown in Figure 5.

4.2.3 Project Flyers and Posters
Kittelson identified the greatest safety performance needs and historically underserved communities in the city, also known as focused neighborhoods, that required focused community outreach – Downtown, Hillsdale, and North Central. Kittelson placed 100 community-specific flyers in English, Spanish, and simplified Chinese, selecting spots in these neighborhoods strategically focusing on activity -centers, i.e., near the schools, transit stops, commercial and retail centers/hubs, community centers, and areas with high pedestrian movement.

4.2.4 Pop-Up Events
This LRSP was developed concurrently with the ongoing 2024 Complete Streets Plan, which organized a series of public engagement events. Because safety is central to both plans’ recommendations, those public activities and feedback inform locations, priorit ies, and input for this LRSP. The 2024 Complete Streets Plan project team conducted a series of pop-up events, of which the LRSP project team participated in two pop- up events (Figure 6). These were conducted at the San Mateo Central Park and San Mateo Farmers’ Market.

At these public engagement activities, City Staff and project team members received input on what infrastructure would best meet the needs of San Mateo’s residents, busine ss owners, workers, and other visitors.

4.2.4.1 Business Cards
Kittelson developed easy-to-carry business cards for the participants that attended the pop -up events. The business cards provided a link and QR code to the project webpage. The business cards were developed in two languages, English and Spanish.

4.2.5 Findings
Figure 7 shows the location of comments received on Interactive Map tool based on user-defined type. Most of these comments include speeding cars near schools and residential areas, intersections with limited access for vulnerable users, inadequate pedestrian crossings, poor visibility, and maintenance issues.

Additionally, some comments are related to traffic congestion, illegal parking, and inadequate infrastructure for bikes. The residents suggested improvements at certain locations such as implementing speed bumps,

April 2, 2024 San Mateo Local Roadway Safety Plan Kittelson & Associates, Inc. Page 29

adding stop signs or traffic lights, improving crosswalks, enhancing bike lanes, increasing enforcement, and narrowing or removal of traffic lanes.

Below is list of key themes of safety issues and concerns from the pop-up events:
◼ Red Light Running and Speeding:
o Red light running at intersections: 12th Avenue/Hobart Ave/El Camino Real, 20th Avenue & El Camino Real, and El Camino Real corridor.
o Speeding on several streets in the City, including El Camino Real, Tilton Avenue, Palm Avenue, and 20th Avenue.
◼ Pedestrian Safety:
o Need for pedestrian crossing signals, signal heads, additional crosswalks, pedestrian related infrastructure improvements near schools and in higher pedestrian activity areas. ◼ Bike Safety:
o Lack of bike lane presence, bike infrastructure, and bicycle lane connectivity. ◼ School Zones:
o Speeding in school zones, safety concerns at school pick-up/drop-off areas. o Suggestions included reducing pedestrian crossing lengths by adding curb extensions at intersections.
◼ Intersection Design:
o Need for stop signs and better visibility.
◼ Traffic Calming Measures:
o Need for more speed humps and speed cushions on various streets, including Alameda de las Pulgas and Delaware Street.
◼ Pavement Conditions:
o Presence of potholes on various streets, including Poplar Avenue, El Camino Real, and Pacific Blvd.

The findings from the data were informed and expanded using community engagement and feedback.

For key themes identified above, if the data findings were supported by community feedback (for example, need for speed management on some city roadways), we addressed those key themes by identifying systemic treatments as discussed in Section 7.2. For site-specific comments from the community, if the data findings supported community feedback and experience, site-specific treatments were recommended at priority locations that address those factors identified, described in detail in Section 7.3.

For key themes and comments from the community that were not informed by the data (for example, maintenance needs on city roadways), we were not able to assess if pavement conditions are associated with an increase in collisions. The City may consider monitoring this as part of their implementation of the LRSP. By incorporating findings from the data and listening directly to community needs, this LRSP reflects data-driven and community-informed desires to improve roadway safety performance in the City of San Mateo.

4.3 Citywide Safety Performance Analysis
Kittelson developed a collision database using the reported collision data from January 1, 2017, through December 31, 2021. The data was cross -checked and supplemented with information from the California Statewide Integrated Traffic Records System (SWITRS), University of California Berkeley’s Transportation Injury Mapping System (TIMS), and City’s internal collision database. Collisions on Caltrans-owned and operated roads such as US 101 and State Route 92 were excluded from the data, while those on at-grade facilities with direct interaction with the City’s roadway network, such as State Route 82, were included. Collisions reported at the ramp terminal intersections that are associated with grade -separated freeways and highways in the City are also included in the analysis database. Duplicate records were also identified and removed. The final dataset is comprised of 1,909 collisions from SWITRS/TIMS and 690 collisions from the City’s internal collision database.

The citywide roadway safety performance is summarized using findings from the following analyses:
◼ Citywide Collision Patterns and Trends, which identifies relevant collision factors such as collision types, primary collision factors, and users involved.
◼ Network Screening, which spatially locates collisions and identifies intersections and segments with the highest collision frequency and severity to determine locations where improvements may have the highest impact.
◼ Statewide Comparison, which compares local collision statistics with statewide data to identify areas for safety improvement.

4.3.1 Citywide Collision Patterns and Trends Summary
This section describes collision patterns and trends for all reported collisions between January 1, 2017 , and December 31, 2021. These statistics helped develop systemic and location -specific countermeasures for safety projects across the city. The following is a summary of key findings from all reported collisions:
◼ 2,599 collisions were reported (an average of 519.8 per year), including 89 fatal or severe injury collisions (an average of 17.8 per year).
◼ Intersection collisions are more frequent than roadway collisions, representing 93% of reported collisions and 92% of fatal/severe injury collisions.
◼ 230 collisions (9% of reported) involved pedestrians, including 31 fatal and severe injury collisions (34% of fatal and severe injury).
◼ 144 collisions (6% of reported) involved bicyclists, including 15 fatal and severe injury collisions (17% of fatal and severe injury).
◼ Sideswipe (26%), rear-end (22%), and broadside (18%) collisions are the most frequently cited collision type.
◼ Improper turning (26%), unsafe speed (15%), and driving or bicycling under the influence (14%) are the most frequently cited primary collision factors.

In this analysis, the project team focused on understanding the overall collision risk factors and primary contributing factors, with an emphasis on their relationship with fatal and severe injury collisions. This is because Caltrans Director’s Policy commits to Safe System Approach to eliminate deaths and serious injuries on California roadways.

Figure 8 and Table 4 summarize the reported collisions by severity in the City of San Mateo. Table 4 also shows a breakdown of City collisions by road users involved. 230 collisions involved pedestrians, 31 of which were fatal or severe injury collisions (1.2% of total collisions, but 35% of fatal and severe injury collisions citywide).

Similarly, 144 collisions involved bicyclists, 15 of which were fatal and severe injury collisions (0.5% of total collisions, but 17% of fatal and severe injury collisions citywide).

Figure 10 shows the temporal trend of traffic collisions from 2017 to 2021. The year 201 8 had the highest number of total reported collisions followed by 2019. Overall, we see a decrease in the total collisions in 2020 and 2021. The share of fatal and severe injury collisions is highest in 2021 (4.3%), followed by 2018 (3.6%). In general, single -year trends are sensitive to probabilistic fluctuations and may not necessarily indicate improved or worsened safety performance. With the COVID -19 pandemic, 2020 and 2021 were not typical and almost all the cities in the United States experienced a decrease in traffic volumes and change in travel patterns in 2020 due to t he pandemic. Associated with this trend, jurisdictions saw a decrease in total collisions but an increase in roadway fatalities and severe injury collisions.

Figure 10 supports this national trend within the City of San Mateo – there were fewer total collisions on City’s roadways in 2020 and 2021, but the proportion of fatal and severe injury collisions was higher compared to prior years. While research is still ongoing, this increase in severe collisions is hypothesized to be associated with higher driving speeds and riskier driving behavior – although there was less driving overall, those driving did so with less traffic on the road and more opportunity to speed. While 2020 and 2021 totals appear lower than previous years, its data should not be directly compared to other years’ collision data or used in isolation as indication of improved roadway safety performance. This is an expected outcome that is correlated with lower levels of travel overall, related to stay-at-home orders and evolving patterns of working from home and reduced travel.

4.3.1.1 Collision Types
Figure 11 and Figure 12 show the most frequently occurring collision types that were reported in the City. Of all the reported collisions, the three most common collision types include sideswipe, rear end, and broadside collisions (68% of all reported collisions). The most common collision types that resulted in fatal and severe injury collisions include vehicle/pedestrian (37% of fatal and severe injury crashes ), vehicle/bicyclist (17% of fatal and severe injury crashes), and broadside collisions (17% of fatal and severe injury crashes).

4.3.1.1.1 Pedestrian-Involved Collisions
Across the five study years (2017 -2021) there were a total of 230 pedestrian-involved collisions as shown in Figure 13. Of thes e collisions , 31 were fatal and severe injury collisions. Pedestrian -involved collisions comprised 9% of all reported collisions but accounted for 35% of fatal and severe injury collisions. Therefore, pedestrian-involved collisions are over-represented in fatal and severe injury collisions. 61% of all reported pedestrian-involved collisions and 58% of fatal and severe injury collisions occurred when the pedestrian was crossing in a crosswalk at an intersection.

4.3.1.1.2 Bicycle-Involved Collisions
Across the five study years (2017-2021) there were a total of 144 bicycle-involved collisions as shown in Figure

14. Of these collisions, 15 were fatal and severe injury collisions. Bicycle-involved collisions comprised 6% of all reported collisions but accounted for 17% of fatal and severe injury collisions. Therefore, bicycle-involved collisions are over-represented in fatal and severe injury collisions. 46% of all reported bicycle-involved collisions and 27% of fatal and severe injury collisions were classified as broadside collisions. The top three primary collision factors for bicycle-involved collisions were wrong side of road, automobile right of way, and unsafe speed.

4.3.1.1.3 Broadside Collisions
Since broadside collisions are most commonly reported for all collisions as well as for fatal and severe injury collisions, broadside collisions were investigated further. Across the five study years (2017-2021) there were a total of 462 broadside collisions as shown in Figure 15. Of these collisions, 14 were fatal and severe injury collisions. Broadside collisions comprised of 18% of all reported collisions but accounted for 16% of fatal and severe injury collisions.

The top three primary collision factors for broadside collisions were automobile right of way, traffic signals and signs, and improper turning.

4.3.1.2 Primary Collision Factors
Reported primary collision factors (PCFs) convey the violation or the underlying causal factor for a collision.

Reporting officers identify a primary collision factor (PCF) for every collision. There are several different PCFs from which they can select. It is up to the officer’s judgement and information available at the scene for them to select the factor that is most relevant to the collision. Officers select one from among a list of PCFs based on violations14 and road user behavior. There may be multiple PCFs that are appropriate for a given collision, but the PCF is the factor identified by the officer as the primary contributing violation/action for the collision.

Figure 16 and Figure 17 show the most frequently occurring PCFs that were reported in the City. Of all the reported collisions, the three most common PCFs include improper turning, unsafe speed, and driving or bicycling under the influence (DUI) (55% of all reported collisions). The three most common PCFs that resulted in fatal and severe injury collisions include pedestrian right of way, DUI, and improper turning (53% of all fatal and severe injury collisions).

Detailed descriptions for each of these PCFs are provided below.

4.3.1.2.1 Improper Turning
Improper turning violations are generally associated with a violation of CVC 22100. CVC 22100 directs how and when right -hand and left -hand turns get made on California roadways. For the City of San Mateo, improper turning violations are mostly correlated with sideswipe, hit object, and head-on collision types.

4.3.1.2.2 Unsafe Speed
Speed violations are generally associated with CVC 22350. CVC 22350 generally prohibits motorists from driving faster than what is considered safe for given driving conditions and circumstances. For the City of San Mateo, unsafe speed violations are mostly correlated with rear end, overturned, and hit object collisions. It is

0.5 times more likely for a collision with a PCF of unsafe speed to result in other visible injury and complaint of pain than for total collisions. Weekday AM and PM peak periods appea r to have more collisions due to unsafe speed, likely associated with increased travel activity.

4.3.1.2.3 Driving or Bicycling Under the Influence of Alcohol and Drug A violation of CVC 23152 is generally associated with driving under the influence violations. For the City of San Mateo, driving under the influence violations are mostly correlated with overturned, hit object, and head-on collisions. It is more likely for a collision with a PCF of driving or bicycling under the influence of alcohol and drugs are to result in a severe injury than for total collisions. Weekend evenings appear to have more collisions due to drivers driving under the influence of alcohol or drugs.

4.3.1.2.4 Pedestrian Right of Way
Violations of CVC 21949 through 21971 are associated with pedestrian right-of-way violations. For the City of San Mateo, pedestrian right -of-way violations are mostly correlated with vehicle/pedestrian and head -on collisions. There is a higher proportion of collisions with a PCF of pedestrian right of way resulting in a fatal or severe injury.

4.3.2 Safety Performance Network Screening
Kittelson analyzed citywide collision patterns spatially and calculated collision severity scores for each intersection and roadway segment. These collision severity scores will ultimately help the City identify priority locations for safety improvement projects, which are discussed further in Section 8 - Recommendations.

4.3.2.1 Methodology

4.3.2.1.1 Collision Severity Score
Kittelson used the equivalent property damage -only score (EPDO score; hereafter referred to as collision severity score) performance measure from the American Association of State Highway and Transportation Officials, or AASHTO, Highway Safety Manual (HSM), which assigns weighting factors to collisions by severity relative to PDO collisions. The collision severity score calculation was performed for all public intersections and roadway segments, not including state highway facilities. This performance measure is described below.

The collision severity score is calculated by multiplying each collision severity total by its associated weight and summing the results, using the following formula:

𝐴𝑛𝑛𝑢𝑎𝑙𝑖𝑧𝑒𝑑 𝐶𝑜𝑙𝑙𝑖𝑠𝑖𝑜𝑛 𝑆𝑒𝑣𝑒𝑟𝑖𝑡𝑦 𝑆𝑐𝑜𝑟𝑒 =
∑ 𝑊𝑖 ∗ 𝑁𝑖∀ 𝑐𝑜𝑙𝑙𝑖𝑠𝑖𝑜𝑛 𝑠𝑒𝑣𝑒𝑟𝑖𝑡𝑖𝑒𝑠
𝑇
Where, Wi = Weight of specified collision severity
N i = Total number of collisions throughout the time -period of analysis T = Time -period of analysis (years)
The collision severity score is annualized by dividing the score by the number of years of collision data used in the analysis. The associated collision severity weights are based on the cost of PDO collisions, provided by the 2022 Caltrans’ Local Roadway Safety Manual. These weights are shown in Table 5.

As shown in Table 5, the collision weights prioritize fatal and severe injury collisions equally to recognize that a death versus a severe injury is often a function of the individual involved (i.e. , age or physical fitness) or of emergency response time. Therefore, both outcomes represent locations where the region may equally value improvements. Moreover, collision weights vary by location due to the relative costs associated with the collision severity at the location types. Specifically, unsignalized intersections have a higher cost for fatal and severe collisions because fatal and severe collisions at these locations tend to result in more severely injured persons on average.

4.3.2.1.2 Intersection Analysis
Kittelson first identified signalized and unsignalized intersections in the City ’s roadway network and then defined collisions as intersection or segment collisions. An intersection collision is defined as a collision that occurs within 250 feet of the intersection. These collisions were spatially joined and summarized in ArcGIS to show the total number of collisions by severity and the respective annualized collision severity scores at each intersection. Where intersections were less than 500 feet from each other, collisions were assigned to the nearest of the two intersections. Collisions occurring more than 250 feet from any intersection were separated to be used in the roadway segment analysis discussed below.

4.3.2.1.3 Roadway Segment Analysis
After completing the intersection analysis, Kittelson used the collisions reported more than 250 feet from the nearest intersection to conduct a separate segment analysis. A Python script in ArcGIS allowed for splitting the San Mateo roadway network into overlapping half -mile (0.5) segments, incrementing the segments by one quarter (0.25) of a mile. This methodology helps to identify portions of the roadway with the greatest potential for safety improvements.

Once the roadway segments were created , the Python script spatially joined collisions to the corridor segment (excluding those identified with intersections as described above) . Like the intersection methodology above, collisions were summarized by severity, and the totals were multiplied by the collision severity weights for roadway segments. The weighted collision severity scores of the collisions were totaled and annualized by the number of years of collision data (five) to generate an annualized collision severity score.

4.3.2.2 Results
To meet the goals of the City of San Mateo, Kittelson performed an intersection and roadway segment analysis based on collision severity score metrics. The results of the intersection and segment analysis helped create an initial list of intersections and corridors with high collision rates. This method highlights the sites that have high frequencies of fatal and/or severe injury collisions which typically warrant further investigation and countermeasure application. These locations are often the most compe titive for HSIP, SS4A, and similar safety-related grant applications, discussed in Section 8 - Recommendations.

4.3.2.2.1 Priority Intersections
Kittelson used all reported collisions to conduct a network screening at all intersections in the City (127 signalized, 1,978 side-street stop -controlled and 2,024 uncontrolled intersections) . Collision severity scores ranged from zero to 124.46. The priority intersections are organized into a Tier 1 and Tier 2 classification based on their collision severity score:
◼ Tier 1 – Priority intersections that have a collision severity score 46 or higher. A threshold of 4 6 was determined since there appeared to be a natural break in the results at this point. ◼ Tier 2 – Priority intersections that have a collision severity score lower than 46 and higher than or equal to 42. A threshold of 42 was determined since there appeared to be a natural break in the results at this point.

Tier 1 and Tier 2 locations are grouped in such a way that the intersections at which there were at least two or more fatalities and/or severe injuries were identified as Tier 1 locations (except two intersections : Norfolk Street & Hillsdale Boulevard and Eldorado Street & 3 rd Avenue). These two in tersections had similar crash severity scores as other Tier 1 intersections which means that there was higher degree of collision severity in other injury classification s. The rem aining intersections were placed in Tier 2, where at least one fatality or severe injury collision occurred in the last five years. Three of these Tier 2 intersections are on Santa Inez Avenue, so if additional funds are available after addressing Tier 1 intersections, these three Tier 2 intersections could be looked at together (as a group) for potential safety improvements.

4.3.2.2.2 Priority Roadway Segments
Kittelson used reported collisions that were not classified as intersection -related collisions to run a roadway segment analysis. There were a total of 104 roadway segment-related collisions out of the 1,159 collisions that were geolocated . Collision severity scores ranged from zero to 51.72. Beginning with the sliding window segment used for the analysis, logical project limits were determined based on roadway characteristics and collision data to support project development. The collision severity scores were recalculated for the resulting roadway segment limits. It was determined that a collision severity score of 33.03 was an appropriate threshold for classifying priority segments. This score indicates that at least one fatal or severe injury collision (or its equivalent) occurred on the roadway segment over the study period.

Table 7 displays the priority roadway segments with their corresponding collision severity score along the segment.

4.3.3 Statewide Comparison
The California 2020-2024 Strategic Highway Safety Plan (SHSP) is a statewide traffic safety plan that provides guidance to influence development of statewide goals, strategies, and performance measures for local agencies and stakeholders statewide.

The SHSP focuses on 16 challenge areas. Thirteen of the challenge areas are compared below to City of San Mateo collision history. The remaining three are not compared because the data available for this project are not readily and reliably provided for these challenge areas. Figure 20 shows a collision share comparison between the City’s collision statistics between 2017 -2021 and the statewide data between 2008 -2017 for each of the challenge areas posed in the SHSP. 20 The City of San Mateo generally has at least two times higher fatal/severe injury shares than Statewide for the following SHSP challenge areas:
◼ Intersections (51% vs 23%)
◼ Pedestrians (36% vs 17%)
◼ Bicyclists (20% vs 7%)
Other categories that show a similar or slightly higher share in San Mateo compared to the statewide averages include:
◼ Aggressive driving (which is similar to the speed-related findings already presented) ◼ Young drivers
◼ Aging drivers
◼ Distracted driving
Aligning with the findings already presented in the sections above, these challenge areas were considered while developing the emphasis areas and used in the goal development for the City of San Mateo.

20 Driver Licensing, Emergency Response, and Emerging Technologies cannot be compared using the collision data since they are not readily and reliability available at this time.

5 EMPHASIS AREAS
According to San Mateo’s collision patterns, locations, movements, behavioral factors, and statewide priority areas, the greatest opportunity to improve roadway safety is to target the following emphasis areas:
◼ Pedestrians and Bicyclists. Non-motorized users are involved in higher shares of fatal and severe injury collisions compared to their representation in all reported severity levels. 35% and 17% of fatal and severe injury collisions involved a pedestrian or a bicycle, respectively. ◼ Intersections. Intersections account for 9 1% (signalized intersections – 40% and unsignalized intersections – 51%) of the total collisions. 92% of fatal and severe injury collisions occurred at intersections (signalized intersections – 39% and unsignalized intersections – 53%). ◼ Improper Turning is a contributing factor in fatal and severe injury collisions citywide and represents a potential emphasis area. 13% of fatal and severe injury collisions had improper turning as their primary collision factor.
◼ Unsafe Speed is a contributing factor in fatal and severe injury collisions citywide and represents a potential emphasis area. 11% of fatal and severe injury collisions had improper turning as their primary collision factor.
◼ Alcohol and Drug Involvement is a contributing factor in fatal and severe injury collisions citywide and represents a potential emphasis area. 17% of fatal and severe injury collisions had improper turning as their primary collision factor.
◼ Aging Drivers, Drivers 65 years and over account for 1 0% of the total collisions and 11% of fatal and severe injury collisions. The collision share comparison with SHSP showed Aging Drivers having a slightly higher share in San Mateo when compared to the statewide average (14% in San Mateo versus 12% statewide).

These six emphasis areas guide the recommended countermeasures, strategies, actions, and implementation plan in this LRSP.

6 COUNTERMEASURES AND STRATEGIES
Addressing emphasis areas in order to improve safety will take a coordinated effort and a combination of the available countermeasures and strategies presented in this section. This section presents multidisciplinary recommendations for the City to consider as they make investments and advancements in improving roadway safety across the City.

6.1 Countermeasures vs. Strategies
Countermeasures: A term used for engineering infrastructure improvements that can be implemented to reduce the risk of collisions.

Strategies: A term used for non-engineering practices that address traffic safety – often related to behavior or components of a Safe System that build a culture of safety.

6.2 Available Countermeasures
These engineering countermeasures are proven effective treatments to reduce collision risk as described in this section. This set of countermeasure treatments have been grouped into five treatment groups that most directly address the City’s collision patterns and trends for fatal and severe injury collisions, and overall collisions:
◼ Pedestrian Related Countermeasures
◼ Bicycle Related Countermeasures
◼ Signalized Intersection Countermeasures
◼ Unsignalized Intersection Countermeasures
◼ Roadway Segment Countermeasures
For each of these groupings, priority countermeasures were identified and summarized based on the collision types addressed, quantitative effectiveness of the treatment document as collision reduction factors (CRFs) and implementation considerations , shown in Table 8. Combining these countermeasures with non - engineering strategies can also target road user characteristics and behavior. The pedestrian and bicycle related countermeasures only apply the crash reduction to pedestrian and bicycle related crashes, while the other countermeasures apply the crash reduction to all crashes (with some exceptions, for example, lighting countermeasure applies crash reduction only to night -time crashes). The safety countermeasure toolbox memorandum submitted to the City in February 2023 is attached in Appendix D.

6.3 Available Strategies
This section discusses the non -engineering countermeasures to improve safety and reduce collisions on roadways in the City, reviewed and referenced from Countermeasures That Work guide25. Non-engineering countermeasures/strategies for the City are grouped into the following, detailed explanation for each of these can be found in Appendix D:

1. Education Strategies

2. Enforcement Strategies

3. Equity Strategies

4. Emerging Technologies

6.3.1 Education Strategies
Education strategies are focused on teaching road users, road safety principles. These strategies can be developed to include interactive activities, comprehensive teaching notes, and information on road safety messages and concepts that can be taught at s chool or in off -school activities. Public education and collaboration help bridge gaps in knowledge that influence roadway behavior.

6.3.2 Enforcement Strategies
Even when engineering countermeasures are implemented, road users failing to adhere to traffic laws can result in collisions of varying severity. Police enforcement can increase driver awareness and consequently reduce traffic collisions. However, enforcement strategies should be undertaken with due caution to avoid inequitable enforcement activities and evaluated to determine the strategy’s impact. The following considerations can help lead to more successful outcomes for roadway safety enforcement strategies:
◼ Police officers should be provided with resources related to primary contributing factors of collisions that will be used for crash reporting.
◼ Campaigns should be tailored to suit the needs of different neighborhoods and demographics and should be designed and carried out to avoid targeting disadvantaged communities and populations. ◼ Enforcement should be conducted with the help of staff support and awareness of the courts. ◼ Enforcement operations should begin with warnings and flyers before moving on to issuing citations.

6.3.3 Equity Strategies
Equity is defined as the fairness with which benefits, and burdens are distributed and how disparities, including those based on age, race/ethnicity, income and gender, are identified and addressed within specific populations (National Safety Council26).

The following equity strategies have been identified for the City of San Mateo:
• Engineering: An equitable approach to engineering countermeasures must consider and should include, but is not limited to:
o Investing in infrastructure in an equitable manner to reduce traffic accidents, prioritizing historically disinvested neighborhoods, or neighborhoods overrepresented for collisions; o Creating contextually sensitive plans and solutions and avoiding one-size-fits-all-solutions.

For instance, infrastructure plans can be designed keeping in mind different kinds of roadway users including children, senior citizens, people with disabilities; o Involving a diversity of people in testing and design to increase safety.

• Education: An equitable approach to education strategies must consider and should include, but is not limited to:
o Developing, executing, and implementing programming with community voices included in the process, particularly those representing disadvantaged and/or highly impacted communities;
o Using images, language, and media that is reflective of the community and audience; o Working with trusted ambassadors, spokespeople, and community leaders to help in the execution of any campaigns or programs.
• Enforcement: An equitable approach to enforcement strategies must consider and should include, but is not limited to,
o Adopting income-based repayment for traffic tickets;
o Understanding whether and how enforcement of traffic safety laws or regulations can exacerbate existing racial, socioeconomic, or accessibility issues, and subsequently working with stakeholders to identify solutions;
o Educating and training those working on enforcement on equitable enforcement practices and techniques;
o Assessing whether new or alternative forms of enforcement can be deployed to effectively address the issue at hand, including automated enforcement and community policing.

6.3.4 Emerging Technologies
New traffic safety technology can enhance the benefits of other engineering, education, enforcement efforts by accelerating road safety understanding using technology, thereby helping transition to safer transportation systems.

7 RECOMMENDATIONS
Following identification of the broader emphasis areas, engineering countermeasures and non-engineering strategies to address those areas, t hese treatments represent improvements that may have the greatest potential to help reduce fatal and severe injury collisions and build a culture of safety in San Mateo. This section summarizes the systemic and location-specific countermeasures that could be implemented across the city to potential location -specific projects, to reduce fatal and severe injury collisions . The countermeasures, identified in Section 6 -Countermeasures and Strategies are based on the corroboration between site visits and observations, community feedback, and collision data analysis.

7.1 Systemic vs. Site-Specific Treatments
Systemic Treatments - The systemic safety approach to roadway safety involves selecting locations for countermeasures based on roadway characteristics that may be correlated with severe collision types rather than identify locations based on collision history. Identified sites may or may not have a history of frequent or severe collisions but will have roadway characteristics associated with collision risk factors. By selecting locations based on roadway characteristics instead of collision history, systemi c treatments may help to proactively reduce the risk of fatal and severe injury collisions. Kittelson identified the following systemic treatments to address the risk factors that were identified through the data-driven and community-informed analysis documented in the Summary of Citywide Safety Performance, Emphasis Areas, and Equity Analysis sections of the LRSP.

Site-Specific Treatments - These projects are identified based on collision history and road data at individual sites to identify and prioritize countermeasures for sites that have a high frequency of fatal and/or severe injury collisions. The priority location list identified in Section 4.3 - Safety Performance Network Screening provides the LRSP’s initial location-specific project locations.

7.2 Systemic Treatments
The list is not exhaustive and other opportunities may arise to implement low-cost countermeasures that may address other emphasis areas not described below (i.e., low -cost improvements from Road Safety Audits (RSAs)).

7.2.1 Leading Pedestrian Intervals (S21PB) & No Right -Turn-on-Red Treatment
When paired, these two treatments are a low -cost countermeasure that can be applied systemically to reduce the risk of pedestrian collisions, especially in areas with a high level of pedestrian activity. According to Assembly Bill AB -2264, Caltrans requires state -owned or operated traffic -actuated signals upon first placement or replacement to include LPI with accessible pedestrian signals (APS) and detectors27.

Research has shown that LPIs may lose their intended benefits when right turns on red that conflict with the crossing are not restricted28. When using an LPI, right turns on red should be restricted in parallel and perpendicular to the treated crossings, since right-turning drivers from both streets would otherwise proceed and conflict with crossing pedestrians. At some locations with highly peaking traffic and with very high volumes of right turns (exceeding 200 vehicles per hour), traffic operations and queuing may be a

concern. NCHRP Report 969: Traffic Control Strategies for Pedestrians and Bicyclists explains some options for these locations:
◼ For LPIs providing a head -start along a minor street, adding an LPI typically has no effect on traffic operations.
◼ LPIs and RTOR restrictions can be implemented for certain times of day, i.e., peak hours of pedestrian traffic.
◼ At locations with very high volumes of right turns, full protection between vehicle and pedestrian movements may be preferred. NCHRP Report 969 offers information on such options. ◼ If the pedestrian phase is push -button actuated, then the additional LPI phase will only be triggered when a pedestrian is present.

Figure 2129 shows locations which are initial candidates for implementing LPIs and RTOR restrictions. The City may choose to evaluate these locations to compare queuing impacts of implementing LPIs at these locations against the safety benefits of providing these treatments. When considering LPIs at these locations, the City should consider intersections near senior centers to determine if longer times are needed to cross the crosswalk. There may be other locations identified with a high level of existing or anticipated pedestrian activity as part of the future plans or developments in review, these treatments can also be applied to those locations.

29 Note that citywide data on LPI presence at intersections was not available in a format to conduct this citywide analysis.

As such, when implementing this countermeasure, the city will need to determine if an LPI has already been implemented.

7.2.2 Signal Visibility Improvements (S02)
At signalized intersections, simple hardware improvements can improve the signal visibility and address patterns of broadside, rear -end, night -time, and red -light running collisions. These hardware upgrades enables drivers to see traffic signals sufficiently in advance to safety negotiate the intersection being approached and have been shown to reduce related collisions by as much as 15 percent. Improvements include but not limited to:
◼ Backplates with retroreflective borders improves signal head visibility during daytime and nighttime conditions.
◼ Lenses with LED lighting or larger lenses may increase traffic signal visibility. ◼ Mounting assemblies include mast arms, span wires, and side -mounted vehicular signals, upgrading these may improve signal hardware longevity.

Figure 2230 shows locations which are initial candidates for implementing signal visibility improvement treatments. There may be other locations identified as part of the future plans or developments in review, this treatment can also be applied to those locations.

7.2.3 Speed Management (R26)
Speed management seeks to lower the vehicular speeds on the roadway, thereby reducing speeding related collisions. Speed management should be addressed comprehensively to encompass all the factors that may influence travel speeds, including road user/driver behavior, roadway design, surrounding land use context, traffic, roadway conditions, posted speed limits, and enforcement. Assembly Bill 645 authorized San Francisco, Oakland, and San Jose to pilot speed camera safety technology in October 2023. Depending on the findings from the pilot program, the City of San Mateo may consider deploying speed cameras at locations in the City that would benefit from reduction in speeds and the likelihood of a collision involving a fatality or a severe injury.

The following two countermeasures were identified for the City:

1. Install Dynamic Speed Feedback Signs/Dynamic Speed Warning Signs

2. Traffic Calming

7.2.3.1 Install Dynamic Speed Feedback Signs
This treatment consists of installing dynamic or variable speed feedback signs on the roadway. Speed feedback signs provide drivers with feedback about their speed in relationship to the posted speed limit.

These treatments provide a message to drivers exceeding a certain speed threshold (or posted speed limit).

The intent of these treatments is to get drivers’ attention and provide them with a visual warning that they may be traveling over the recommended speed on the roadway.

7.2.3.2 Traffic Calming
Traffic calming is the use of mainly physical roadway design measures to slow motor vehicles as they move through urban, commercial, and residential neighborhoods. These treatments also help to reduce cut - through traffic and improve the safety of non-motorized users by reducing the potential for higher speed and higher severity conflicts. This se ction describes additional engineering measures that can be used for traffic calming. Many pedestrian and bicycle related treatments also provide traffic calming benefits. Enforcement

30Note that citywide data on signal visibility improvements at intersections was not available in a format to conduct this citywide analysis. As such, when implementing this countermeasure, the city will need to determine if a signal visibility improvement has already been implemented.

71 of 337

strategies such as speed feedback signs and high visibility saturation patrols can also be effective for traffic calming.

This group of treatments include Speed Hump, Chicane, Bulb -out, Raised intersections, and Choker/Pinch Point. Figure 2331 shows locations which are initial candidates for implementing speed management treatments. There may be other locations identified as part of the future plans or developments in review, these treatments can also be applied to those locations.

31Note that citywide data on speed management treatments was not available in a format to conduct this citywide analysis. As such, when implementing t his countermeasure, the city will need to determine if speed feedback sign or a traffic calming measure has already been implemented.

7.2.4 Centerline Hardening
Centerline hardening is an intersection treatment that reduces the speed of turning vehicles and improves pedestrian visibility, an example is shown in Figure 24. The basic hardened centerline treatment consists of five pieces of rubber curb and bollards and/or rubber speed bumps installed on the centerline and extending at a maximum of six feet into the intersection. The treatment can be implemented in a low-cost fashion with quick build materials.

Because centerline hardening can calm left turns, this treatment can be proactively implemented at intersections with left -turn geometry that otherwise allow for high -speed left turns. This treatment can be installed at intersections or midblock crossing locations on major and/or minor arterials in urban areas32.

Figure 24: Centerline Hardening Example in Oakland, California

Source: Kittelson & Associates, Inc.

7.3 Site Specific Treatments
This list will be updated at an interval determined appropriate by the City based on implementation (e.g., annually, every three to five years) using the collision severity score (equivalent property damage only), critical collision rates, or similar safet y performance measure consistent with the AASHTO Highway Safety Manual. Table 9 lists the site-specific projects in San Mateo.

The matrix is organized by short-term and longer-term opportunities. This list is not exhaustive, as many of these treatments can be applied elsewhere in the City of San Mateo. Appendix E shows the priority project location concepts, along with recommended treatments.

8.1 Plan Updates and Evaluation
This LRSP is in line with the Safe System Approach, federal and state safety guidance, and is Safe Streets and Roads For All (SS4A) compliant. Updates to the LRSP should be every three to five years. City staff will create and implement a process to report on the performance measures listed above annually. As collision and other data are available, the City can evaluate the plan’s progress (i.e., about five to seven years) and effectiveness. The City and its partners should take a holistic look at current d ata trends and technologies, and implementation progress to determine whether the plan should be updated and to what extent (e.g., to incorporate innovative technologies or practices, to modify action items based on what is and is not working, to address emerging collision trends).

Evaluation should be included as part of each activity so that actions, projects, and partnerships can be modified as needed. The ability to adjust the plan will better help build a road to success and, ultimately, help the City achieve its long-term goal of eliminating preventable fatal and severe injury collisions by 2050.

8.1.1 Project Evaluation
The City will evaluate the effectiveness of projects to inform ongoing efforts to reduce fatal and severe injury collisions. For the projects in the LRSP, this will likely mean follow-up studies to evaluate the effects the treatments have had on fatal and severe injury collisions after they are implemented.

8.1.1.1 Systemic Project Evaluations
Systemic projects are meant to be deployed broadly across locations with the potential for collisions, not necessarily where collisions have recently occurred. Therefore, a simple before -after evaluation of a single site will not accurately capture the effects of the systemic program. Instead, relatively comparable sites that have been treated with similar countermeasures (e.g., LPIs at signalized intersections) during the same time period should be grouped together in the before-after evaluation.

8.1.1.2 Site-Specific Project Evaluations
Site-Specific projects can be evaluated through a before-after comparison study of each site. The Highway Safety Manual describes different methods for these studies. The most common is the simple before -after study, which involves directly comparing collision data from the period before the treatment was applied to collision data from the period after the treatment. However, this leaves out the effect of time trends and other variations that tend to occur in collisions. More robust methods include the “Emp irical Bayes” and the comparison group methods. Both methods require more data and, in some cases, may not be practical for the city. Some of the weaknesses of the simple method can be overcome by using a larger sample. To accomplish this, relatively compa rable sites that have been treated with similar countermeasures (e.g., installing flashing beacons as advance warning at signalized intersections) during the same time period can be grouped together.

8.1.2 Project Tracking
The City can track the status of projects in two ways. One means would be through a spreadsheet or database that is regularly updated. Another would be through a GIS-based tool with each project mapped with supporting information (e.g., estimated cost, benefit, year programmed, priority, description). This would be updated regularly to capture when projects are completed. Information important to capture after a project is completed includes:
◼ Project cost (actual),
◼ Construction start and end dates,
◼ Description of project as constructed, including countermeasures applied and locations, ◼ Links to as-built plans or construction drawings and any studies or analyses conducted, and,

81 of 337

April 2, 2024 San Mateo Local Roadway Safety Plan Kittelson & Associates, Inc. Page 74

◼ Information on collisions (by type and severity) before and after the treatment, along with the results of the before-after study.

The success of this plan will be judged on its results. Performance measures are included in this section to evaluate the success of the plan in eliminating fatal and severe injury collisions, as well as to evaluate the success of the City and its partners in implementing this plan.

Measures the City can use to evaluate the ongoing success of the LRSP towards achieving its ultimate goal include:
◼ Fatal collisions reported quarterly in total and by emphasis area. ◼ Fatal and severe injury collisions reported annually in total, per capita, and by emphasis area using data from the most recent year.
◼ Frequency of communication with identified partners on safety initiatives. ◼ Annual expenditure on safety improvements.

Further, the City and its partners could develop performance measures to evaluate the effectiveness of individual measures (e.g., has improved software for 911 allowed dispatchers to take more emergency calls? Did adding LPIs result in fewer broadside or pedestrian -related crashes at the intersection?). Developing these measures will be the responsibility of the implementing organization and will depend on the availability of data to use for the evaluation.

The purpose of the ATP is to encourage increased use of active transportation modes by increasing the proportion of trips made by bicycle or on foot and i ncreasing non-motorized user safety; reduce greenhouse gases; enhance public health; and ensure that disadvantaged communities fully share in the benefits of the program.

Website: http://www.dot.ca.gov/hq/LocalPrograms/atp/

9.2.6 State-Local Partnership Program (LPP)
Managing Agency: CTC
The Road Repair and Accountability Act of 2017 (Senate Bill 1) created the Local Partnership Program (LPP), which is modeled closely on the Proposition 1B State Local Partnership Program. The purpose of the Senate Bill 1 LPP program is to provide local and regional transportation agencies that have passed sales tax measures, developer fees, or other imposed transportation fees with a continuous appropriation of $200 million annually from the Road Maintenance and Rehabilitation Account to fund road maintenan ce and rehabilitation, sound walls, and other transportation improvement projects. Consistent with the intent behind Senate Bill 1, the CTC intends this program to balance the need to direct increased revenue to the State’s highest transportation needs while fairly distributing the economic impact of increased funding. LPP provides funding to local and regional agencies to improve aging Infrastructure, road conditions, active transportation, and health and safety benefits.

9.2.9 State Highway Operation and Protection Program (SHOPP) Managing Agency: Caltrans
The State Highway Operation and Protection Program (SHOPP) is the State Highway System’s (SHS) “fix-it-first” program. It funds repair and preservation, emergency repairs, safety improvements, and some highway operational improvements on the SHS. Although SHOPP is intended for projects on statutorily designated State-owned roads, highways (including the interstate system) and bridges, it can be used for associated bicycle and pedestrian facilities. Revenues for the SHOPP are generated by federal and State gas taxes and are fiscally constrained by the State Transportation Improvement Program Fund Estimate that is produced by Caltrans and adopted by the California Transportation Commission.

Website: http://www.dot.ca.gov/hq/transprog/shopp.htm

9.2.10 State Transportation Improvement Program (STIP)
Managing Agency: CTC
The State Transportation Improvement Program (STIP) is a biennial five -year plan adopted by the CTC for future allocations of certain state transportation funds for state highway improvements, intercity rail, and regional highway and transit improvements. State law requires the CTC to update the STIP biennially, in even- numbered years, with each new STIP adding two new years to prior programming commitments. CTC staff recommendations are based on the combined programming capacity for the Public Transportati on Account (PTA) and State Highway Account (SHA) as identified in the fund estimate adopted by the CTC.

Projects must first be nominated by the Metropolitan Transportation Commission in its Regional Transportation Improvement Program (RTIP), or by Caltrans in its Interregional Transportation Improvement Program (ITIP) to be included in the STIP that is adopted by the CTC.

Website: http://www.catc.ca.gov/programs/stip/

9.2.11 Affordable Housing and Sustainable Communities (AHSC) Program
Managing Agency: California Strategic Growth Council
The purpose of the AHSC Program is to reduce GHG emissions through projects that implement land -use, housing, transportation, and agricultural land preservation practices to support infill and compact development, and that support related and coordinated p ublic policy objectives. The AHSC program includes transportation focuses related to reducing air pollution, improving conditions in disadvantaged communities, supporting or improving public health, improving connectivity and access to jobs, increasing options for mobility, and increasing transit ridership. Funding for the AHSC Program is provided from the Greenhouse Gas Reduction Fund (GGRF), an account established to receive cap -and-trade auction proceeds.

Technical Memorandum

INTRODUCTION
Kittelson & Associates, Inc. (Kittelson) prepared this memorandum as a synthesis of roadway safety-related documents for the City of San Mateo and adjacent jurisdictions. This memorandum highlights the state/regional/jurisdiction-specific crash trends and current noteworthy safety practices, policies, and/or initiatives that have been implemented at a state, regional and local level. This document provides guidance for the safety analysis methodology, emphasis areas, policies, and strategies for the Local Roadway Safety Plan (LRSP) project and a summary of recent roadway safety improvement related efforts undertaken by the City.

The memorandum starts with a discussion of the project’s background and focuses on the findings from Federal Highway Administration (FHWA) and California statewide safety plans and best practices. This is followed by regional policy and programs and city-specific planning documents. The memorandum also summarizes guidance for proven countermeasures and strategies and concludes with a discussion of the most relevant safety-related grant programs.

Project Background
The LRSP will create a framework for developing a comprehensive transportation safety management program to identify potential safety issues in the City and apply strategic and proven solutions to address them. The LRSP process will combine stakeholder input with data analysis to produce a community-driven and data-driven approach to addressing transportation safety performance. Increasing understanding of trends in driver behavior, crash characteristics, and locations helps the City identify safety improvements.

These safety improvements are intended to reduce crash frequency and severity for roadway users in the City of San Mateo. The LRSP will include mission, vision statement, goals, a list of emphasis areas, high- priority locations, and safety countermeasures and strategies based on crash history, local agency collaboration, and stakeholder and community feedback.

The LRSP would apply the Safe System approach in addition to traditional systemic approach, hotspot analysis, and site-specific approaches. The Safe System approach takes a broad view to systemically evaluate risk across an entire roadway network rather than at certain locations (as is done in site-specific approach). It also adopts a proactive approach to address safety concerns to help prevent crashes rather than a reactive approach based on historic crash data (i.e., waiting for crashes to happen). A systemic approach recognizes that the location of reported crashes alone is not sufficient to determine potential 155 Grand Avenue, Suite 505

countermeasures. This is particularly true for low volume roads where crash densities are comparatively low, and for specific crash types (such as pedestrian-vehicle crashes) that occur less frequently while typically having more severe outcomes. The Safe System and systemic safety approach considers the presence of conflicts between different roadway users and develops crash risk factors to identify locations likely to benefit from proactive safety treatments and have the greatest potential to improve roadway safety.

Potential conflicts, site visits, and assessments of driver behavior also help inform decisions for prioritizing and implementing countermeasures to consistently reduce crash risk.

Federal
FHWA Safe System Approach
In January 2022, the United States Department of Transportation released its National Roadway Safety Strategy1 that adopted the Safe System Approach as its core strategy. In February 2022, Caltrans released Director’s Policy 362 which commits to adopting the Safe System Approach to achieve its vision to eliminate fatalities and serious injuries on California’s roadways by 2050 and provide safer outcomes for all communities.

As opposed to traditional road safety practices that attempt to modify human behavior and prevent crashes, the Safe System Approach focuses on modifying overall transportation system design to anticipate human errors and lessen impact forces to reduce crash severity and save lives. The Safe System Approach also acknowledges that the human body is vulnerable in terms of the amount of kinetic energy transfer it can withstand. This vulnerability is considered when designing and operating a transportation network to minimize serious injuries and fatalities. Therefore, it is crucial that the responsibility is shared by those who design and operate the transportation system. In a Safe System, all stakeholders work together which include, but are not limited to, road users, transportation system managers, law enforcement, emergency responders, and vehicle manufacturers. Additionally, it is also crucial to provide redundancy in the system so that multiple levels of protection are available to help prevent crashes that lead to severe injuries and deaths.

These important recognitions of changing how we approach traffic safety are being prioritized as traffic deaths continue to be unacceptably high numbers across the country. In 2020, there were 38,824 traffic- related fatalities in the United States3. In California, there were 3,798 fatalities in 20184. These numbers do not include serious injury crashes that also significantly change the lives of people involved and the communities they live in. The Safe System Approach aims to eliminate fatal and serious injuries on roadways and will requires change in traffic safety culture, standards, practices, and partnerships.

There are three key components of the Safe System Approach to understand: the Safe System “approach,” “principles,” and “elements.” In addition, the term “Safe System” is singular to depict an overall safe road system rather than individual elements that would be addressed in isolation or separately.

San Mateo Local Roadway Safety Plan: Document Review Memorandum - FINAL Introduction Kittelson & Associates, Inc.

The Safe System “ approach ” is the
broadest term and describes all aspects
of the Safe System which are shown in
Figure 15.

Six Safe System “ principles ” encompass
the fundamen tal beliefs that the
approach is built on. A successful Safe
System approach weaves together all six
principles. The six principles are shown
around the outside ring of the graphic.

Five Safe System “ elements ” that are
conduits through which the Safe System
approach must be implemented. These
promote a holistic approach to safety
across the entire roadway system and
acknowledge the shared responsibility
principle. Making a c ommitment to zero
deaths means addressing every aspect
of crash risks through these five elements
that accommodate human mistakes and
injury tolerances. The elements are
presented in the middle ring of the
graphic.

Roadway system managers in the Safe System Approach use a proactive approach to safety to try to address safety concerns before crashes occur, contrasting with traditional road safety practices which are reactive and address safety concerns after crashes occur. This involves using crash data, roadway design characteristics and employing a data-driven approach to identify crash patterns and trends associated with crash risk. Transportation system managers then systemically implement proven safety countermeasures at all locations matching those crash risk factors to mitigate against future crashes.

Finally, redundancy is key in reducing crash occurrence in a transportation system. All parts of the system should be strengthened so that if one part fails, other parts of the system still protect roadway users. A simple implementation of this would be rumble strips that protect people when their own ability to be safe road users is compromised by distractions or drowsiness.

Relevance to the San Mateo LRSP:
◼ Firmly establishes death and serious injuries are not acceptable as the fundamental basis for roadway safety planning and design.
◼ Encourages proactive approaches for safety and shared responsibilities by all parties involved in roadway planning, design, and operations (including road users). ◼ Emphasizes a data-driven and community-informed approach to developing safety improvements and strategies.

FHWA LRSP Guidance
In addition to the Safe System Approach discussed above, FHWA also provides a framework of the key steps in developing an LRSP in Developing Safety Plans – A Manual for Local Road Rural Owners (2012). The FHWA LRSP development process is captured in Figure 2, with four primary steps:

1. Establishing Stakeholders

2. Using Safety Data

3. Choosing Proven Solutions

4. Implementing Solutions
The first step of the plan involves convening a diverse group of stakeholders as the Project Development Team (PDT) to help support and inform the planning process by sharing diverse views on roadway safety and help identify needs. This should be followed by a detailed analysis using available roadway and crash history data to understand crash patterns and trends, potential crash risk factors, and emphasis areas for addressing roadway safety in the local jurisdiction. While data is an important and useful tool to help define safety issues, it is often incomplete for a variety of reasons. These might include inaccurate reporting, an inability to capture safety issues like near-misses, and difficulty pinpointing streets or areas people currently avoid because they feel unsafe. Therefore, FHWA recommends LRSP projects to take a data-informed approach to planning, using data analysis in conjunction with engagement with the PDT and community to highlight lived experience in addition to data to develop a more comprehensive view of the transportation safety issues. Following the analysis and with input from the PDT, a selection of proven countermeasures most applicable should be developed and refined to form a countermeasure toolbox and inform the implementation plan for the LRSP.

Relevance to the San Mateo LRSP:
◼ Highlights the importance of incorporating diverse group of stakeholders and the community. ◼ Emphasizes a data-driven approach to develop priorities and strategies. ◼ Focuses on selecting and deploying proven safety countermeasures.

State
California Strategic Highway Safety Plan (SHSP)
The 2020-2024 Strategic Highway Safety Plan (SHSP) is a statewide, coordinated safety plan providing a comprehensive framework for reducing highway fatalities and severe injuries on public roads in California.

It identifies key safety needs and guides investment decisions towards strategies and countermeasures with the most potential to save lives and prevent injuries.

The aspirational goal for the plan is to have zero fatalities and serious injuries on California public roads consistent with other Toward Zero Deaths (TZD) initiatives. Working to make zero fatalities and serious injuries on California roadways a reality will require a traffic safety culture that promotes collaboration and innovation from all safety sectors and a collective commitment.

The SHSP identified California’s 16 challenge areas, or areas that should be the main topics for roadway safety in California. Of the challenge areas, six were identified as high priority areas, having the greatest opportunity to reduce death and serious injury, and are presented below. Those challenge areas can be compared with the result of the LRSP’s crash data analysis and can inform the process of identifying high- priority locations for crash risk and cost-effective countermeasures. ◼ Active Transportation: Pedestrians and Bicyclists
◼ Impaired Driving
◼ Intersections
◼ Lane Departures
◼ Speed Management / Aggressive Driving
Initially, the SHSP approached traffic safety using the five E’s: engineering, enforcement, education, emergency services, and emerging technologies. In 2021, state transportation officials shifted focus to adopt guiding principles that integrate social equity, integrate the Safe System Approach (described in the section above), and encourage the use of proven countermeasures and emerging technologies.

SHSP partner agencies have begun to implement strategies to eliminate traffic deaths and serious injuries using their guiding principles and challenge areas. This LRSP will build from the framework created by the SHSP by incorporating ideas that align with the challenge areas and guiding principles established to address safety at the state level.

Relevance to the San Mateo LRSP:
◼ Identifies state priorities, challenge areas and goals to align with the LRSP. ◼ State challenge areas will be used to compare against San Mateo crash history to determine consistency or differences with state crash priorities. ◼ Opportunities to align and leverage statewide strategies, partnerships, and approaches with the LRSP. ◼ State priorities help identify potential state funding opportunities for LRSP projects and strategies.

Regional
MTC Regional Safety/Vision Zero Policy
The MTC Regional Safety/Vision Zero Policy establishes a strategy for working with partner agencies to support equitable and data-driven action towards eliminating traffic deaths and serious vehicular injuries in the Bay Area by 2030.

The document promotes a three-pronged approach to enhance safety in the region. First, MTC staff will work on enhancing the region’s and jurisdictions’ access to reliable and consistent data by integrating several available sources into a single regional safety data repository. Second, MTC will use data to inform and develop regional policy and support legislation that has been proven effective, such as lowered speed limits and automated speed enforcement. Finally, and dependent on resources available, MTC will support jurisdictions by providing technical assistance with safety planning.

The following principles are adopted in the policy:
◼ Regional safety leadership
◼ Data driven
◼ Equity focused
◼ Evidence-based policy and legislation
◼ Education and engagement
Funding
One potential role of MTC is to provide technical assistance to jurisdictions, which includes funding advocacy for the region. In fact, MTC has applied and received funding for the development of a Regional Safety Data System and the development of a State of Safety in the Region Report.

An important piece of MTC’s Vision Zero policy is the use of incentive programs to encourage the adoption of Vision Zero plans and safety best practices. As an action item under the regional safety leadership principle, the Policy notes that MTC will engage and incentivize leadership across local jurisdictions in prioritizing safety and work towards aligning funding investments with safety goals. For example, local agencies with a Vision Zero Plan may designate Connected Community Priority Development Areas, which gives them access to additional funding opportunities.

In January 2022, MTC adopted the third round of One Bay Area Grant funding (OBAG 3), which includes more than $750 million in federal funding for projects from 2023 to 2026. For local programs, County Transportation Agencies (CTAs) will assist countywide outreach and submit a project nomination list to MTC for consideration. Funds will be available for a wide range of project types, including safety programs such as Safe Routes to School.

Relevance to the San Mateo LRSP:
◼ Establishes regional vision for collaborative and data-driven approach to eliminate traffic death and serious injury.
◼ Incentivizes Vision Zero safety plan development through the Connected Communities Safety Policy with additional funding for safety improvements.
◼ Emphasizes equity in roadway safety management planning and implementation. ◼ Opportunity to coordinate the LRSP with regional safety data bank and priorities.

C/CAG of San Mateo County Safe Routes to School Reports This section summarizes findings from San Mateo County Safe Routes to School Five-Year Evaluation (2010- 2011, 2014-2015 School Years)6 and San Mateo County Safe Routes to School High Injury Network Report7.

San Mateo County Safe Routes to School Five-Year Evaluation In 2010, the C/CAG partnered with the San Mateo County Office of Education (SMCOE) to develop and implement the San Mateo County Safe Routes to School program to the 25 school districts in San Mateo County, in which elementary schools and middle schools in the City of San Mateo are affiliated with San Mateo-Foster City Elementary School District, and high schools in the City are affiliated with San Mateo Union High School District. The goal of the program was to improve the health, well-being, and safety of children by encouraging and enabling them to walk and bike to school.

In 2014-2015, the program conducted four walking and biking audits, held over a thousand assemblies, bike rodeos, and educational events. 133 schools and/or organizations participated in the program. In the City of San Mateo, 14 schools participated in the program and conducted Safe Routes to School Activities, such as:
◼ Bike after school program
◼ Tour de SMFC schools
◼ Route maps
◼ Bike education programs
◼ Walk to school days
◼ Walking school bus
In the Laurel Elementary School project, the County, SMCOE, San Mateo-Foster City School District, and the City of San Mateo partnered to construct the Laurel Elementary School Sustainable Stormwater and Safe Routes Demonstration Project in May 2015. Road safety improvements included the following:

◼ Shorter crossing distance and better visibility with marked crosswalks and curb extensions ◼ Safe walking/waiting area with one-way drop-off and pick-up area delineated by bollards ◼ Expanded and secure bike rack area
Though the San Mateo County walk to and from school rates (26% walking from school and 24% walking to school) were higher than the national average (16% walking from school and % walking to school), the parent survey identified the following in the 2014-2015 school year:
◼ Speeding traffic along route
◼ Unsafe intersections
◼ Too much traffic along route
◼ Stranger danger
◼ Distance to school
◼ Lack of adults to walk with
Walking and Biking Audits
In the five-year period, 61 walking and biking audits have been conducted in San Mateo County. Audits are conducted by engineering professionals, school staff, City staff, and law enforcement. Four walk audits were conducted at schools in the San Mateo-Foster City School District in the 2016-2017 evaluation year.

The audit team conducts site visits to evaluate the quality and availability of pedestrian and/or bicycle

facilities that provide access to school, as well as on-site facilities. The document also includes a toolbox of potential engineering improvements that could be applied to roadways within the County.

Relevance to the San Mateo LRSP:
◼ Opportunity for collaboration across agencies to create safe routes for students and integrate strategies across the LRSP and Safe Routes to School program. ◼ Identifies a toolbox of potential improvements for school-specific concerns and risks. ◼ Surveys include community-perceived barriers to walking and biking to school, which could inform development of targeted countermeasures for the LRSP.

San Mateo County Safe Routes to School High Injury Network Report This report details the process and outcomes of a youth‐based high injury network (HIN) analysis. The HIN identifies segments in a road network where many pedestrian and bicycle collisions have occurred, as a means for prioritizing future infrastructure improvements. In the context of a Safe Routes to School (SRTS) program, the HIN can be used to identify segments near schools where students traveling to or from school may face increased safety challenges.

According to this report, in the City of San Mateo, out of the 925 collisions reported from 2014 to 2020, 175 are within one-quarter mile of a school. There are 203 youth-involved collisions Citywide, in which 51 are within one-quarter mile of a school. The top five safety priority corridors are listed below, all of which are within the City of San Mateo or pass through the City:
◼ State Highway 82 (El Camino Real)
◼ North Delaware Street
◼ North San Mateo Drive
◼ East Hillsdale Boulevard
◼ North Humboldt Street
The top four collision factors that create potential barriers to walking and biking to school identified in the annual SRTS Parent/Caregiver survey are speeding traffic along routes, unsafe intersections, too far from school, and too much traffic along routes. All of these factors were identified in 15 percent or more of the responses from San Mateo-Foster City School District or San Mateo Union High School District.

The top five collision factors identified in the San Mateo School Safety Analysis (2014 – 2020) based on crash analysis are shown in Table 1.

Local
San Mateo 2030 General Plan
The San Mateo’s General Plan is the community’s planning guideline that defines the long-term vision and provides the framework for all zoning and land use decisions within the community. The General Plan seeks to establish a balance between the need for new growth and development and the preservation of the City’s high quality of life. In 2010, the City of San Mateo updated its General Plan - “Vision 2030, which provides an extension of the prior General Plan and incorporates new goals and policies pertaining to climate change and sustainability.

The Land Use and Circulation Elements of the plan include goals and policies that address roadway safety.

The related policies are described below.
◼ Land Use Policy 3.3 - El Camino Real. Pedestrian activity and safety should be encouraged as part of the improvement project of the commercial boulevard.
◼ Circulation Policy 2.5 - Traffic Studies. Traffic impacts caused by a development project are considered to be unacceptable and warrant mitigation if there may be safety hazards created. ◼ Circulation Policy 3.4 - Hillsdale Station. Relocating the Hillsdale Station northward. The planned modifications consist of installing a raised platform on an aerial viaduct, which will provide safer access and easier transfers to buses and shuttles.
◼ Circulation Policy 3.5 - Grade Separation of Rail Line. Promoting the elimination of existing at grade crossings to improve local circulation and safety.
◼ Circulation Policy 3.7 - San Mateo Rail Corridor Transit-Oriented Development Plan (Corridor Plan). To improve east-west access via new grade-separated rail crossings at 28th and 31st Avenues, which would improve local traffic circulation and pedestrian safety. ◼ Circulation Policy 4.1 - Bicycle Master Plan. Implement Bicycle Master Plan’s recommended programs and projects to create and maintain a fully-connected safe and logical bikeways system.

157 of 337

December 8, 2022 Page 11
San Mateo Local Roadway Safety Plan: Document Review Memorandum - FINAL Introduction Kittelson & Associates, Inc.
◼ Circulation Policy 4.7 - Pedestrian Safety. Pedestrian safety shall be made a priority in the design of intersection and other roadway improvements.
◼ Circulation Policy 4.8 - Pedestrian and Bicycle Mobility Needs. Balance pedestrian mobility and bicycle accessibility and safety with vehicular congestion when considering intersection improvements to address level of service degradation.
◼ Circulation Policy 4.10 - Bikeway Systems. Review the City’s planned bikeways system for adequacy, consistency and connectivity throughout the City to facilitate ease of use and safety for the users including adequate parking for bicycles.
◼ Circulation Policy 4.11 - Hillsdale Bicycle and Pedestrian Over Crossing. The General Plan notes to make bicycling safer, more convenient, and more accessible in all reaches of the City through strategic capital improvements, programming, and better internal coordination of bicycling projects.

The City is updating its General Plan currently (2040 General Plan), which is the plan that expresses the community’s vision for how the City will look, feel, and change over the next 20 years.

Relevance to the San Mateo LRSP:
◼ Citywide safety-related goals and policies to be integrated for consistency in the LRSP. ◼ Coordination of long-term citywide improvements with LRSP recommendations and strategies. ◼ Potential opportunity for LRSP recommendations to inform ongoing General Plan update.

City of San Mateo Citywide Pedestrian Master Plan (2012) The Citywide Pedestrian Master Plan is a blueprint for the City of San Mateo to improve the pedestrian environment, secure funds dedicated to pedestrian safety and livable communities, and increase the number of walking trips. The Plan provides a broad vision, strategies, and actions for improving the pedestrian environment in the City.

Safety is identified as one of the six goals of the Plan. Specifically, the City seeks to reduce the number of pedestrian related crashes, injuries and fatalities by 50 percent from 2010 levels by 2020. This is assumed to be accomplished through the design and maintenance of sidewalks, streets, intersections, and other roadway improvements such as signage and lighting, and landscaping; as well as best practice programs to enhance and improve the overall pedestrian safety.

This document examines where pedestrian improvements are needed in San Mateo based on pedestrian commute patterns and historic crash data. The analysis reveals the need for continuous walkways and enhanced crossings at locations with high pedestrian-related crash rates. High concentration of crashes occur near Downtown area, El Camino Real, Delaware Street, East Poplar Avenue, West Hillside Boulevard, 1st Street, 5th Street, and Alameda de les Pulgas. These findings are based on 2000-2009 Caltrans’ Statewide Integrated Traffic Report System (SWITRS) crash data.

The document explores both programmatic and engineering improvements that may help improve pedestrian safety. Programmatic improvements include encouragement, education, and enforcement programs. These programs can ensure that more residents know about new and improved facilities, learn the skills they need to integrate walking into their activities, and receive positive reinforcement about integrating walking into their daily lives. In addition to the programmatic improvements, the document recommends the following engineering enhancements:
◼ Standardize sidewalk design by land use

San Mateo Bicycle Master Plan (2020)
The 2020 San Mateo Bicycle Master Plan is the culmination of over a year of robust community engagement, data analysis, planning and design work. This Plan is an update of the City’s 2011 Bicycle Master Plan and serves as a blueprint for expanding and improving the San Mateo bicycle and mobility network in the coming years. The goals of the Plan are as follows:
◼ Seamless bicycle connectivity to major destinations throughout the City ◼ Equitable infrastructure investments that prioritize underserved communities ◼ Safe and comfortable riding for people of all ages and abilities ◼ A significant mode shift from driving to bicycling and other forms of micromobility for trips around the City
◼ Creation of a robust active transportation community in San Mateo To achieve the safety goal, the Bicycle Plan adopts the following objectives and metrics related to bike safety, also shown in Table 2:
◼ Install low-stress facilities and treatments that reduce conflicts between bicyclists and other roadways users including drivers, pedestrians, and users of micromobility systems (e.g., people on e-scooters and so on.).
◼ Provide safe, direct bicycle and micromobility connections across barriers, including intersections, freeways, and the Caltrain tracks.
◼ Ensure facilities are comfortable to use through increased lighting and regularly scheduled maintenance.

Citywide bicycle-involved crash data was analyzed to understand the crash patterns and trends. From 2013 to 2017, 205 bicycle-involved crashes were reported in the City, of which none resulted in fatalities and 184 resulted in injuries. The top six collision factors, which cumulatively accounted for over 70 percent of the bicycle crashes, are automobile right of way violation, other hazardous movement, improper turning, wrong side of road, traffic signals and signs, and unsafe speed.

Geographically, bicycle crashes are not evenly distributed throughout San Mateo. Four crash hotspots are identified in the Plan: San Mateo High School, Downtown San Mateo, Between Hillsdale and Hayward Park Caltrain Stations, and Junction between US 101 and Hillsdale Boulevard.

The Plan also proposes a future bicycle network for San Mateo with 101 miles of new facilities and 56 miles of existing facilities based on community and City staff input, site visits, evaluations of existing conditions, results from the crash analysis, and best practices in bicycle network planning and design. Because “Interested but Concerned” bicyclists - riders who have interest in bicycling but also have safety concerns when interacting with vehicular traffic - represent the largest potential for mode shift away from private vehicles in San Mateo, the proposed network aims to create a dense low-stress network suitable for this classification of riders. In addition, the Bicycle Master Plan also recommends the City to complete a series of spot improvements, including signal improvements, geometric changes, and supplementary pavement marking, to enhance safety and comfort at intersections when implementing the proposed bicycle network.

Relevance to the San Mateo LRSP:
◼ Establishes goal to reduce bicycle-related crashes, injuries, and fatalities to align with the LRSP. ◼ Identifies bicyclist safety-related concerns and hotspots for consideration in the LRSP. ◼ Proposes bicycle facilities and intersection improvements that would enhance safety and comfort of bicyclists for consideration and coordination with the LRSP.

Strategies and Countermeasures
FHWA Proven Safety Countermeasures
FHWA’s Proven Safety Countermeasures initiative (PSCi) is a collection of 28 countermeasures and strategies effective in reducing roadway fatalities and serious injuries. These treatments have been identified based on their quantitative safety benefits and consistency with national, state, and local safety goals. These strategies are designed for all road users and all road types. Each countermeasure addresses at least one of four safety focus areas:
◼ Speed management
◼ Intersections
◼ Roadway departures
◼ Pedestrians
Relevance to the San Mateo LRSP:
◼ Countermeasures are based on latest research and can make significant and measurable impacts on roadway safety for consideration in the City’s toolbox.

FHWA Crash Modification Factors (CMF) Clearinghouse
A crash modification factor is used to compute the expected number of crashes after implementing a countermeasure on a road or intersection. The CMF Clearinghouse provides a searchable database of research-developed CMFs along with guidance and resources on using CMFs in road safety practice. Each CMF study is assigned a star quality rating to reflect the cumulative performance of the study conducted.

The CMF Clearinghouse is updated on a regular basis to add recently developed and documented CMFs.

Relevance to the San Mateo LRSP:
◼ Provides a resource to identify applicable countermeasures and obtain expected effectiveness for consideration in the LRSP’s priority project development and countermeasure toolbox.

FHWA Pedestrian and Bicycle Safety Guide and Countermeasure Selection System
Pedestrian Safety Guide and Countermeasure Selection System (PEDSAFE) and Bicycle Safety Guide and Countermeasure Selection System (BIKESAFE) are interactive tools maintained by FHWA. PEDSAFE and BIKESAFE provide practitioners with information and tools to review and select engineering and roadway infrastructure improvements to reduce pedestrian and bicyclist injuries and fatalities. The countermeasures section includes a comprehensive list of engineering, education, and enforcement countermeasures, as well as details of each, including its description, purpose, considerations, safety effect, and cost.

Relevance to the San Mateo LRSP:
◼ Establishes best practices to proactively identify locations for walking and bicycling safety improvements and involve citizens in the planning process.

NHTSA Countermeasures that Work
Countermeasures That Work: A Highway Safety Countermeasure Guide for State Highway Safety Offices is a basic reference published by the National Highway Traffic Safety Administration (NHTSA) to assist State Highway Safety Offices (SHSOs) in selecting effective, evidence-based countermeasures for ten traffic safety problem areas: Alcohol- and Drug-Impaired Driving; Seat Belts and Child Restraints; Speeding and Speed Management; Distracted Driving; Motorcycle Safety; Young Drivers; Older Drivers; Pedestrians; Bicycles; and Drowsy Driving. The guide describes major strategies and countermeasures that are relevant to SHSOs; summarizes strategy/countermeasure use, effectiveness, costs, and implementation time; and provides references to the most important research summaries and individual studies.

Relevance to the San Mateo LRSP:
◼ Identifies safety strategies that have the most evidence of effectiveness based on published research with a focus on targeting human factors for consideration in the LRSP.

Caltrans Local Road Safety Manual
The goal of Local Road Safety: A Manual for California’s Local Road Owners is to maximize the safety benefits for local roadways by encouraging all local agencies to proactively identify and analyze their safety issues and to position themselves to compete effectively in Caltrans’ statewide, data-driven call-for- projects. Due to the wide variety of local agencies, roadway types, and project types, currently, there is a vast range of safety documents and analysis tools. Without clear and simple safety guidance for locals, many agencies take a “reactive” approach to safety. This manual integrates the set of manuals designed specifically for rural road owners published by FHWA, along with Caltrans’ ongoing research, to offer local agencies focused roadway safety information in one manual.

The manual provides an easy-to-use and comprehensive framework of the steps and analysis tools needed to identify locations with roadway safety issues and the appropriate countermeasures. It also includes key safety activities that every local agency should conduct regularly with the objective of reducing the number and severity of crashes within their jurisdiction.

Relevance to the San Mateo LRSP:
◼ Documents the state recommended approach to roadway safety management. ◼ Establishes state crash reduction factors for state-adopted countermeasures. ◼ Provides guidance that aligns with statewide HSIP grant funding opportunities.

Most Relevant Grant Programs
Safe Streets for All (SS4A) Grant Program
The Bipartisan Infrastructure Law (BIL) established the new Safe Streets and Roads for All (SS4A) discretionary program with $5 billion in appropriated funds over the next 5 years. The SS4A program funds regional, local, and Tribal initiatives through grants to prevent roadway deaths and serious injuries. It supports Secretary of Transportation Pete Buttigieg’s National Roadway Safety Strategy and the Department’s goal of zero deaths and serious injuries on our nation’s roadways. For the fiscal year (FY) 2022, up to $1 billion of funds are available and are to be awarded to support planning, infrastructure, behavioral, and operational initiatives to prevent death and serious injury on roads and streets involving all roadway users, including

163 of 337

pedestrians; bicyclists; public transportation, personal conveyance, and micromobility users; motorists; and commercial vehicle operators.

The following activities are eligible for the SS4A program:
◼ Comprehensive safety action plans
◼ Planning, design, and development activities in support of an Action Plan (like an LRSP) ◼ Projects and strategies identified in an Action Plan (like an LRSP) There are two types of SS4A grants: Action Plan Grants and Implementation Grants. To be eligible for an Action Plan Grant, a local agency must be requesting funds to develop or complete an Action Plan, which an LRSP is equivalent to if addressing federal requirements or requesting funds for activities that support or enhance an existing Action Plan. To pursue an Implementation Grant, a local agency must have a safety Action Plan in place and must be requesting funds to carry out projects and strategies identified in the Action Plan. When eligible for both, applicants may only apply for an Action Plan Grant or an Implementation Grant, not both.

The required and recommended elements of the Action Plan, summarized from the Self-Certification Eligibility Worksheet are shown in the section below. An applicant is eligible to apply for an Action Plan Grant that funds supplemental action plan activities, or an implementation Grant, only if the following two conditions are met:

Relevance to the San Mateo LRSP:
◼ One of the larger competitive grant funding opportunities of implementing safety strategies and improvements.
◼ Grants are not limited in the type of safety opportunity and can fund strategies ranging from capital improvements to hiring additional staff to support education or enforcement activities. ◼ Emphasizes the importance of equity and community engagements, which are the goals of the LRSP shared by the City.

Highway Safety Improvement Program (HSIP)
The Highway Safety Improvement Program (HSIP) is one of the core federal-aid programs, aiming to achieve a significant reduction in traffic fatalities and serious injuries on all public roads. California’s share of HSIP funds is split between the State HSIP for state highways and the Local HSIP for local roads, in which the Local HSIP will be applicable to the LRSP.

In order to apply for the HSIP funds, Caltrans requires an agency to have completed their LRSP or an equivalent plan. The LRSP must be updated and validated at least every five years. A specific safety problem must be identified, and the proposed countermeasure(s) must substantially address the condition.

Normally HSIP calls for projects are made at an interval of two years. The proposed projects are generally evaluated based on the Benefit/Cost (B/C) Ratios (BCRs).

Relevance to the San Mateo LRSP:
◼ Frequent (biennial) and larger grant funding opportunity for capital improvements. ◼ LRSP is required to be eligible for future cycles of HSIP funding. ◼ Requires data-driven identification of locations to identify locations with the greatest potential for safety improvement.

California Office of Traffic Safety (OTS) Grants
The California Office of Traffic Safety’s mission is to effectively administer traffic safety grants that deliver innovative programs and eliminate traffic fatalities and injuries on California roadways. To be eligible, the project must use the funds for one of the ten traffic safety priority areas identified by NHTSA (as discussed in the NHTSA Countermeasures that Work section above). The project must provide traffic safety data that demonstrates how it will save lives on CA roadways, which would be consistent with the data-driven approach of the LRSP. In addition, the project must demonstrate the effect using performance measures with one-year of funding.

Relevance to the San Mateo LRSP:

Provides funding for education and enforcement strategies aimed at addressing human factors in roadway safety.

Summary
This memorandum summarizes planning documents, safety approaches and best practices, and funding opportunities (where applicable) from FHWA, NHTSA, USDOT, State of California, MTC, C/CAG, and City of San Mateo. As opposed to traditional road safety practices that attempt to modify human behavior and prevent crashes, the Safe System Approach focuses on modifying transportation system design to anticipate human errors and lessen impact forces to reduce crash severity and save lives. The systemic safety process from FHWA informs the benefits of evaluating crash risk across an entire roadway network rather than at certain locations. These safety policies and initiatives will help the City of San Mateo address documented crash trends and inform decision making related to the systemic safety process. Kittelson will consider national and state safety evaluation practices to implement an effective approach specific to the City of San Mateo.

RE: 27516 - San Mateo LRSP: Community Engagement Summary Memo DRAFT

INTRODUCTION
Kittelson & Associates, Inc. (Kittelson) prepared this memorandum to summarize the community outreach and engagement efforts conducted for the Local Roadway Safety Plan (LRSP). In February 2023, Kittelson developed a Community Outreach and Engagement Plan (Engagement Plan) which was informed by discussions with City’s staff. The Engagement Plan outlined the following goals for community engagement. ◼ Communicate timely information to the public, stakeholders, and partners throughout the project ◼ Actively seek public and stakeholder input prior to key milestones during the project ◼ Provide meaningful public involvement opportunities
◼ Demonstrate how public and stakeholder input has influenced the LRSP’s development ◼ Seek participation of potentially underserved, disadvantaged communities ◼ Ensure consistency with applicable state and federal laws and regulations, as well as local policies, goals, and objectives.

The planned engagement activities were tailored towards the unique character of the City of San Mateo and informed by discussions with City staff. Through these strategies, and in partnership with City staff, Kittelson engaged appropriate stakeholders and community groups to better understand safety issues, needs, and safety performance improvement opportunities within the City of San Mateo. Table 1 provides an overview of engagement strategies used and their reach.

PROJECT WEBPAGE
Kittelson collaborated closely with the City staff to create a project webpage (accessible at www.cityofsanmateo.org/SafetyPlan), which was hosted on the City's website. This dedicated webpage served as a one-stop shop for updates and information related to the LRSP. The primary goal was to actively engage the community, offering a platform for residents to learn about initial findings from the collision data and share their safety concerns and comments regarding walking, biking, driving, and using public transit in San Mateo using the interactive web map.

The webpage featured an array of valuable resources, including an overview of the LRSP, details on upcoming events, project updates, an interactive web map, a story map, and access to relevant documents. The information about the website was publicized using social media channels, business cards, and flyers.

Story Map
Kittelson developed the story map and the link was provided in the project webpage. Kittelson completed data analysis of crash trends in the City and compiled examples of safety countermeasures (or improvements) that can address these crash related trends in the Story Map. A Story Map is an interactive web-based tool that provides information on the overview of LRSP, citywide crash patterns and trends, preliminary data analysis findings, countermeasures list, and a link directing users to interactive map. A total of X,XXX people viewed the story map as of October 31, 2023. An exported PDF of the story is included in Appendix A.

PROJECT FLYERS
As part of the Engagement Plan, Kittelson identified the greatest safety performance needs and historically underserved communities in the City that required focused community outreach - Downtown, Hillsdale and North Central. Kittelson placed 50 flyers, selecting spots in these neighborhoods strategically focusing on activity-centers, i.e., near the schools, transit stops, commercial and retail centers/hubs, community centers, and areas with high pedestrian movement (See Figure 1).

The flyers included crash information related to the neighborhood and information directing residents to project website. The flyers were translated in Spanish and Simplified Chinese language in addition to English. A sample flyer is shown in Figure 2 and all flyers are included in Appendix B.

BUSINESS CARDS
Kittelson developed easy-to-carry business cards for the participants that attended the pop-up events. The business cards provided a link and QR code to the project webpage. The business cards were developed in two languages, English and Spanish (See Figure 3). A total of 100 business cards were distributed at the pop-up events.

INTERACTIVE MAP
The interactive map was utilized to get location-specific feedback from communities throughout the City.

A total of 507 comments were received between early June 2023 through September 2023 after Labor Day, September 8, 2023. Of the total comments, 57 percent (289) of the comments were in focused neighborhoods. Duplicate comments were removed during the review. Figure 4 shows the location of comments by user defined type. All the comments are shown in Appendix C.

Most of these comments include speeding cars near schools and residential areas, intersections with limited access for vulnerable users, inadequate pedestrian crossings, poor visibility, and maintenance issues.

Additionally, some comments are related to traffic congestion, illegal parking, and inadequate infrastructure for bikes. The residents suggested improvements at certain locations such as implementing speed bumps, adding stop signs or traffic lights, improving crosswalks, enhancing bike lanes, increasing enforcement, and narrowing or removal of traffic lanes.

San Mateo LRSP- Community Engagement Summary Interactive Map Kittelson & Associates, Inc.

Kittelson reviewed and categorized the
interactive map comments using the Safe
System Approach by Federal Highway
Administration (FHWA) (See Figure 5).

Unlike traditional road safety practices
that focus on modifying human behavior,
the Safe System Approach focuses on
modifying transportation system design to
anticipate human errors and build
redundancy in the system to reduce
fatalities and severe injury crashes. It
acknowledges the vulnerability of the
human body and promotes creating a
forgiving roadside environment that
requires shared responsibility among
stakeholders to design and operate a safe
transportation system.

The comments were categorized using
three out of five elements of the Safe
System Approach.
◼ Safer People: The major concern highlighted by the community is people speeding on roadways and failing to yield to pedestrians and bicyclists. Additionally, there were comments regarding people running red lights, parking in the bike lane, illegal parking near the intersections and red curbs. Some of these comments were coupled with poor connectivity for active transportation users and roadway design.
◼ Safer Roads and Safer Speeds: The community raised concerns about the intersection and roadway design. Concerns include obstruction of driver’s view of pedestrian and bicyclist at intersections and driveways. A few intersections lack proper traffic controls to allow vulnerable users to safely cross the streets. Some comments highlighted the presence of longer crosswalks and missing sidewalks, which made walking experience stressful at certain locations. There were comments regarding bike lane connectivity, especially on major roadways. Residents identified roadways that have speeding related concerns which does not promote a safe environment for pedestrians and bicyclists.

Based on the interactive map comments, roadway segments and intersections with highest number of comments are listed in Table 2 and Table 3, respectively.

POP-UP EVENTS
Kittelson participated in two pop-up events along with the Complete Streets Plan project team that were organized by the City (shown in Figure 6). The pop-up events were held in early July 2023, with the first one at San Mateo Central Park on 4th of July and the second at Farmers Market on July 8, 2023. Kittelson met with over 200 people at both the pop-up events.

The key themes from the residents' comments were:
◼ Red Light Running and Speeding:
o Red light running at intersections: 12th Avenue & El Camino Real, 20th Avenue & US 92, and El Camino Real corridor.
o Speeding on several streets in the City, including El Camino Real, Tilton Avenue, Palm Avenue, and 20th Avenue.
◼ Pedestrian Safety:

Figure 6: Pop-up Events in July 2023

San Mateo LRSP- Community Engagement Summary Next Steps Kittelson & Associates, Inc.
o Need for pedestrian crossing signals, signal heads, additional crosswalks, pedestrian related infrastructure improvements near schools and in higher pedestrian activity areas. ◼ Bike Safety:
o Lack of bike lane presence, bike infrastructure, and bicycle lane connectivity. ◼ School Zones:
o Speeding in school zones, safety concerns at school pick-up/drop-off areas. o Suggestions included reducing pedestrian crossing lengths by adding curb extensions at intersections.
◼ Intersection Design:
o Need for stop signs and better visibility.
◼ Traffic Calming Measures:
o Need for more speed humps and speed cushions on various streets, including Alameda De Las Pulgas and Delaware Street.
◼ Pavement Conditions:
o Presence of potholes on various streets, including Poplar Avenue, El Camino Real, and Pacific Street.

NEXT STEPS
The City of San Mateo LRSP will be a data-driven and community-informed safety plan. The community engagement activities were an important part of the decision-making process, and the priority projects, and the LRSP will reflect the views of the wider community in the City. The following highlight some of the key areas where community participation and feedback will be used in developing or informing the LRSP:
▪ Identifying areas of concern with respect to traffic safety performance that do not have historic crash data – getting community feedback on near misses, high travel speeds in residential/commercial neighborhoods, and any other safety performance concerns in the City. ▪ Gathering community feedback on the emphasis areas identified from the crash data, trends, and crash patterns throughout the city.

This community feedback will be accounted for in the identification of priority locations and countermeasures, and in shaping the goals, mission statement, actions, and policies that the City will adopt as part of this LRSP.

About San Mateo's LRSP
The City of San Mateo is developing a Local Roadway
Safety Plan (LRSP) to better understand traffic safety
issues, establish safety goals and identify priority
locations for potential safety improvements across the
City.

Funded by a Caltrans grant, the LRSP provides an
opportunity for the local jurisdictions to evaluate
roadway safety performance through data analysis and
identify areas that need improvement. The plan will
provide a range of strategies including engineering,
enforcement, education, equity, and emergency
services to address safety concerns.

The City's LRSP will outline key crash patterns, trends, priority locations for potential projects, and
recommendations for developing an on-going local road
safety management process for the City.

The total number of crashes per year increased every
year through 2019, with a steep decline in 2020 due to
the COVID-19 pandemic. The City's trend was
consistent with national trends with fewer total crashes on City's roadways in 2020 and 2021, but the
proportion of fatal and severe injury crashes was higher compared to prior years.

Improvement Types
This section presents examples of safety treatments
that can help address crash trends identified in the City.

The full list of treatments will be included in the LRSP document.

Pedestrian Related Treatments
Pedestrian-related treatments were identified as one of the priority countermeasures for the City because
pedestrian-involved crashes were overrepresented
among fatal and serious injury crashes in the City.

Pedestrian-involved crashes make up nearly 36% of all
fatal and severe injury crashes but only 9% of total
crashes.

20th ave from Alameda to El Camino cars are going up to 35-40mph especially late afternoon to early evening this is a daily occurrence. There is a high school, and a preschool as well as other businesses. The cars pay no attention to pedestrians trying to cross the stree or pull out of their driveways Driving 5

Now that the lighter traffic due to the pandemic is returning to pre-pandemic congestion, the roads leading to and at the intersection of South Grant and 19th Avenue by the YMCA is a bottleneck problem. With the current developments in the area, more traffic is a problem all day, and especially at commute times at the start and after 3pm/end of the work day, with many cars on these particular roads and intersection. Motorists block the intersection at high traffic times and cars back up on the connecting roads. Nearby Fiesta Gardens school children/families drop-off and pick-up should also be considered. Seniors, those with mobility problems, and pedestrians need consideration for enough time to walk at those crosswalks.

Impatient and aggressive drivers are a concern. Safety is a concern. That intersection is not setup to handle that amount of traffic at high peak times of the day.

Thank you to the rep at San Mateo's July 4th event for informing me of this feedback opportunity; I was not aware of it. 5

Cars are speeding down the hill on Alameda here, creating a dangerous condition for the many kids walking and running among the high schools. Please consider a speed hump at the bottom of the hill on Alameda just before Alta. There is also not a crosswalk between 23rd ave and 26th ave so kids are crossing where they can. you can see the worn out path in the median. finally, all of Alameda needs tighter curbs to reduce speeds turning right at all locations. cars racing down the street not only is unsafe but discourages more walking and biking. Walking 2 146930
A light or stop sign at any part between poplar and peninsula on North Delaware St. the speed of cars and lack of useable sidewalks for young children in strollers or kids coming and going from school is a huge issue 24 hours a day. Driving 1 146960
I have lived on Dwight Road since 1984 and the intersection at Peninsula and Dwight and Delaware has really become dangerous. I walk over to the Starbucks in the Woodlake Shopping Center every day and very often I see cars running the Red Light both coming up and going down Peninsula. I have almost been hit a few times. Since this is the border between San Mateo and Burlingame neither police department seems to be concerned with it. A person was killed a few years ago just one block east at Peninsula and Stanley. That prompted someone to install a flashing light crosswalk. Either the city of San Mateo or the City of Burlingame really needs to take a look at this intersection often and actually witness the people who gun their motors and flagrantly run the light way after it has turned red. I know that going east on Peninsula is The City of San Mateo and going west is The City of Burlingame but someone needs to step up and protect people at this intersection. I would say if a police vehicle was parked near there and was able to view the intersection that within an hour they would see at least 2 high speed red light violations.Since our block has already brought this up at the Lyon Hoag Traffic Calming meetings a couple of years ago and nothing has been done I am not getting my hopes up. There have been many vehicle accidents here and on your map you have it listed as a " Priority Intersection. If at all possibel please see what can be done to help protect us all at this dangerous intersecƟon.

Thank you very much for your time. Walking 1

We need a 4-way stop at this intersection. East/West moving traffic is fast-moving with no stop signs, and there is a lot of foot traffic due to community growth, the Church located at the intersection, and Tilton's role as a thoroughfare for pedestrian traffic to-and-from B St.Driving 12 146962
We live along this 2 block stretch. Cars speed past on their way to the left turn/freeway approach at exorbitant rates! Just today we saw a vehicle nearly get rear-ended by someone doing 50+ along N Delaware Street. At night it sounds like a drag race along this stretch.

Dangerous for those of us backing out of driveways, crossing street on foot, and anyone who is unlucky enough to be in front of these speeders. Driving 3 146963
This intersection is very problematic. As you are aware the turn signal on the south east corner has been knocked down numerous times. In addition school drop off and pick up at Saint Matthews creates congestion and safety risks on El Camino baywood and Baldwin. I have contacted the school numerous times, and they have made no change. Moreover, left hand turns at this light or like a game of chicken or similar to the old video game Frogger. I have personally witnessed two accidents at this intersection in three years of living here and have almost been hit several times by people running the red light when I was turning left. I’m not sure what to suggest, but I hope this intersection will receive some attention. Driving 1 146964
Very unsafe intersection on El Camino Real, Baldwin, Baywood and De Sabla. Lots of car accidents there. My main concern is for pedestrian safety, particularly at night, on the crosswalk parallel to El Camino (western side) connecting De Sabla and Baywood. A number of times I had to run quickly on this crosswalk. Cars, turning left or right to either Baywood or De Sabla have no separate light just for turns. This causes them to turn quickly with no regards to pedestrians on the crosswalk. This is particularly dangerous at night since the awkward intersection for 5 roads is poorly lit. Is there any way to make this intersection safer, particularly for pedestrians? Walking 5

I am a resident of State Street and frequently cross the intersection of State Street and Delaware to go to the grocery store or to the high school track with my toddler. This intersection is absolutely the most dangerous intersection in the area. It is heavily used by pedestrians including families with young children and high school students walking to and from school. Delaware is two lanes on each side and there is no stop sign in either direction.

Visibility is limited due to parked cars. Cars often speed through this intersection and I have personally seen accidents happen at this intersection as well as many near misses. I believe that a stop sign in all directions is necessary in addition to flashing lights for pedestrians to cross such as the flashing lights used further down Delaware near the high school. Walking 1 146966
As a pedestrian, I was nearly struck by an SUV turning left from Hacienda onto W Hillsdale Blvd. While crossing, cars often begin moving towards me from the opposite side of the intersection while I am in their direct path in the crosswalk. This intersection feels incredibly unsafe as a pedestrian, and would benefit from protections and traffic calming.Walking 1 146967
It feels dangerous to be a pedestrian at this multi-lane, four-way stop. Cars have started rolling towards me in many cases. As a major intersection on the path to multiple bus stops and the Hillsdale Caltrain station, this intersection should be safe for pedestrians.Walking 2 146968
I am a resident of state street and there is a huge problem at the intersection of Claremont and state street. Cars use this massive intersection to do donuts at all times of the day. In addition, state street has no stop signs here so it is a huge hazard coming from Claremont and many people run the stop sign coming from Claremont making it dangerous for cars coming down State. I believe either a 4 way stop or a traffic circle would make a huge difference in the safety of this intersection. Driving 2

Crossing El Camino Real on the way to the Hillsdale Caltrain is terrifying as a pedestrian; there are so many lanes of traffic and often a very long wait at the crosswalk. Walking 8

I am a resident of state street and cars are constantly speeding down our street at 50mph+.

They use it as a drag strip because it is so wide, flat, long and straight: I have children and pets and I am extremely concerned for their safety.

Merging north onto 101 from E Hillsdale Blvd during the morning rush hours feels very dangerous. People trying to exit onto 92 will move into the merge lane. When the 92 exit gets backed up, the merge lanes turn into a dead standstill while the left lanes are moving at highway speeds. The merge here is also very short, giving little margin.

Turning from Monte Diablo on to N Amphlett (especially left) is often dangerous due to limited visibility. Cars are often parked illegally further obstructing the view, but even when not, visibility is limited. Maybe some of the convex mirrors mounted along the sound barrier wall could help?

Driving anywhere along Tilton is stressful due to it being a narrow road with cars always parked on it. If there's a vehicle coming in the opposite direction, there's often mere inches of clearance - and drivers often are going too fast for the space and visibility.Driving 3 146994

Currently if you are using the cross walk from the Franklin Templton campus on the south side of this intersection you often seen cars coming through several seconds after the crosswalk light turns on.

I agree. Drivers don't have great visibility when turning right from 31st onto N El Camino.

Maybe one of those larger curbs that make it harder for drivers to turn quickly would help? That might be hard to add due to the unique merge that happens here on northbound traffic.1 147005 146984
Any driver turning right from the 101 north exit onto Hillsdale Blvd has to pull into the crosswalk to get enough visibility to turn right. I have never walked to any of the shops north of 101 from the south because I don't want to play Frogger with cars and die.

Maybe if cars were not able to turn right on red from this off ramp it would be improved, but I'm not sure how to enforce that. 3

This is pretty minor, but drivers turning left from Park Pl onto Saratoga south get confused by the large insertion. Sometimes they stop when they see the red light for Saratoga south, even though it is expected to see a red light from the street you are turning left onto. Maybe add some of those baffles to the stop lights so that drivers turning left are less likely to see the red light? The geometry of this intersection makes that hard to add I'd imagine...Driving 0 147007
Got hit by a car exiting this parking lot a couple months back, thankfully it was a sedan so I managed to go over the hood and not sustain any injury. There's poor visibility for exiting cars and cars generally go way too fast on the ECR which adds to stress. Walking 1 147009
This double stop line is AWFUL. People coming out of the 76 gas station should be forced to turn right and go around the round about instead of trying to turn left. I’ve seen so many accidents here. Also people coming out of the village and just rolling entirely through the 4 way light to try and get up to Hillsdale and out.

There needs to be a safe bike/ped crossing here. It's the obvious place to cross between the paths marked on this map and access to the Village via Curtiss St., especially now that Village residents have to walk farther to the relocated Caltrain stop. Reducing Franklin eastbound to one lane has helped but how about adding a real crosswalk and flashing lights like at Baze Rd.Walking 6 147013
For a pedestrian crossing 4th & El Camino, the experience can be frightening. Cars turning south onto El Camino frequently ignore or discover at a very late time pedestrians crossing El Camino with the light.

I propose that 3rd and 4th Avenues be made one way between El Camino and the the 101, westbound and eastbound respecƟvely.

Not only would this reduce the pedestrian issue at both 3rd and 4th Ave, it would make for tremendously better traffic flow on 3rd & 4th, reduce illegal u-turns into parking places, eliminate waiting to turn left against on-coming traffic, and improve pedestrian safety at every crosswalk Driving 0

Please consider a 4 way stop at this intersection. Currently there are only stop signs on Flores.

Cars are flying through the intersection driving on 29th ave. The stopped cars on Flores also has a hard time seeing the cars driving fast on 29th because of all the parked cars around this intersection. The stopped cars need to inch forward on Flores to see past parked cars and there are many close collisions because of the fast driving 29th cars. Driving 0

I live next to 1st and S Ellsworth and regularly see drivers confused by KEEP CLEAR zone at this intersection. Drivers often mistake the Keep Clear boundary line as a stop line and will pull all the way into the intersection to get to the line.

As a pedestrian crossing 2nd Ave at San Mateo Drive can be scary, especially at night.

Becauseof the weird shape of the intersection, drivers turning right/east from San Mateo Dr onto 2nd Ave cannot see pedestrians in the cross walk until they have completed the turn.

My wife and I live on North Delaware Street between Peninsula Avenue and Poplar Avenue.

This stretch of road has seen its increase in unsafe drivers speeding down this corridor after San Mateo HS school hours are over. A suggestion for solution would be to create roadway speed bumps spread across the Peninsula Avenue/Poplar Avenue corridor especially high enough to reduce vehicle speeds within 15mph. Recommend 2 roadway speed bumps between Peninsula Avenue and State Street. 4 roadway speed bumps between San Mateo Union HS District Building to Poplar Avenue. Driving 1

Please either add stop signs on N Delaware Street at the intersection section with State Street or add Pedestrian Walking Flashing Lights to warn drivers who constantly speed in this area.

When driving Eastbound on 4th in the left lane, if stopped at a red light at Delaware, it looks like you're supposed to go straight, into the right lane after the intersection. However, due to the street becoming a 1-way street, you're supposed to go into the left lane after the intersecƟon.

Please consider making 3rd and 4th Avenues into, two lane, one-way couplets between ECR and 101. A 'green wave' could be installed to time signals for slow progression through downtown. Something like 15MPH would be ideal. This has been done in San Francisco on Valencia, Folsom and other streets and has made traffic way less intimidating. The extra space could be allocated for protected bike lanes. Everybody wins - traffic flows slowly but smoothly, speeding gets reduced so safety increases, people biking finally get some high quality facilities.Driving 3 147098

Flashing lights have been added to this crossing but are not very effective. I cross here almost daily and drivers often ignore the flashing lights. What would be most helpful are two changes:
1) curb extensions into the street so that drivers can see pedestrians waiting to cross and 2) a restriction on parking on the north west side of Delaware. The cars that park on that side near the crossing obstruct the view of pedestrians who are crossing from the northwest corner of the crossing. 4

This crosswalk is extremely dangerous, despite the flashing crosswalk lights. I once was driving and stopped for a pedestrian to cross. The driver behind me sped around to my left into the turning lane (that feeds into the CVS parking lot) to pass me, not aware that there was a pedestrian crossing. The pedestrian was nearly struck by the impatient driver making an illegal pass. This crossing should have those lane dividing cones to prevent cars passing each other thru the crosswalk similar to the ones by the fire station on E 3rd avenue near the approach to 101. Walking 3

Something needs to be added to the blind curves on Palm Ave between 25th and 20th to prevent passing - aggressive drivers regularly pass bicyclists in on-coming traffic. Also, Palm in general needs treatment to make it clear bicyclists are welcome and encouraged.Bicycling 3 147145

This corner of Baldwin and Ellsworth is far too wide to encourage safe driving. Drivers treat the extra wide lane as a right turn lane, and turn right without checking to see if there are pedestrians on their right, regardless of if the pedestrian walk sign is on. Drivers are often unaware that the downtown area has leading pedestrian indicators, as they are more focused on looking at oncoming traffic to their left on Ellsworth. We should narrow the lanes on Baldwin down to force drivers to consider pedestrians as they make their right hand turn on red. 1

Getting off is very challenging. Getting onto it from 3rd is almost impossible.

Cars speed up to approx 35 mph along the street from Alameda to the stop sign at Isabelle.

There are 2 schools along this street, an elementary and a high school. There are also people with physical disabilities who use the sidewalks and cross intersections and at least one person in a motorized wheel chair who uses the street. A stop sign at Stratford or other traffic calming systems would be helpful. Driving 0

Stratford is a narrow street and difficult to drive when there is a lot of activity on the street.

Cars going in opposite directions often have to try to pull over and stop for each other, dodge each other, or slowly and carefully creep by each other.

Southbound on N Claremont St entering E Poplar Ave has poor visibility for approaching cars in both directions on Poplar.

This new bike lane is a terrible design. It forces cars to make a right-hand turn in front of cyclist. In a perfect world, everyone should come to a complete stop, look both ways, etc. In reality, most people, cyclists and cars, run this stop sign all day long. As a cyclist, it is much safer to navigate traffic and merge lanes while I'm moving.

Speeding regularly occurs here, as well as families and children walking across the street without crosswalks at this nor the nearby intersection at 2nd/Lawrence Rd and Fremont.

East-bound 31st Ave lane narrows thru Hillsdale Mall then widens to 3 lanes at El Camino making it ver dangerous for cyclist crossing El Camino.

1)There should be a bike lane on the narrow section thru the mall in both directions of 31st Ave

2) To continue E bound on 31st, a cyclist would either have be in the right turn lane, the straight thru lane or try to get to curb and on to sidewalk to await the traffic light. None of the options is safe, especially the right turn lane & sidewalk where driver don’t look for pedestrians or cyclists.

West bound 31st is also a nightmare for cyclist, where there is suddenly 4 lanes after crossing El Camino, one if which is a right turn lane, again endangering cyclist. Then right after Sailer Dr it squeezes to 1 lane and of course no bike lanes. It dangerous for cyclists at the mall underpass as it is poorly lighted and there are no bike lanes. Don’t understand why bike lanes were put in a slightly wider road. Bicycling 2

It would be nice if there were a pedestrian crossing here (preferably grade-separated) to access the entrance to Hillsdale train station. It would also improve access from the station to bus stops on El Camino and save people from needing to walk along El Camino, where cars are speeding by at 40 mph or more.

It would also provide access to the train station for cyclists, so they can cut through the less- busy mall streets instead of riding on El Camino (VERY dangerous) or 31st Ave.Walking 1 147210

This section of Alameda de las Pulgas doesn't see very much traffic for a 4-lane road, so the two outer lanes should be converted into bike lanes. This would make existing traffic drive a little bit slower (people drive too fast) and make it safer for cyclists. Bicycling 5 147212
Put a stop sign here on 28th Ave. Right now it's really confusing because there are already stop signs on 31st Ave. It's quite strange to have a T intersection with a nonstop intersecting route.

To exit the school parking lot, there is a supposedly right turn only when exiting on N Deleware, and there is so much traffic on the other side of the school trying to exit on Poplar, especially when drivers are trying to get to the S bound 101 entrance on Poplar. All this traffic is causing safety hazards for pedestrians and drivers. There needs to be some sort of traffic control at drop off and pick up hours. Lots of traffic equals upset drivers and commuters. More stop signs on N Delaware would be great to slow down drivers and let the pedestrians in the area (students mostly) get around safely. It would also help the locals who walk to shopping.

The volume and speed of the traffic on Bermuda Drive is a safety risk for pedestrians. Drivers routinely treat these three blocks as extended freeway entrance and exit ramps. Horns honk if anyone has to slow down or tap their breaks. In addition, drivers seldom stop at the stop sign at Grant when turning on to Bermuda Dr .

There appears to be no enforcement of speed limits and drivers respond accordingly.

Thank you for the new signage regarding School Speed limits attempting to address this problem further down Bermuda by Fiesta Gardens School. However, the sign on east bound Bermuda just past Texas Way is a bit confusing. It states “School Speed Limit 25 when children are present.†This clearly implies the speed limit is higher when children are not present, but I assume this is not the case! Walking 1

I cross this crosswalk 6 times a week.

I regularly get challenged by cars that are turning across the crosswalk turning from Saratoga onto Hillsdale.

Currently, the intersection of State Street and N. Claremont Street is a 2-WAY STOP causing cars going along N. Claremont Street only to stop.

There's also an increase in jaywalking to the food truck which is extra dangerous for cars turning off of 3rd ave at night. Driving 2

Crossing is a little inconvenient for bikes especially crossing from the east side as only one side has a cross walk. It requires bikes go the opposite direction and either keep going on the side walk or wait to cross again at the light to go to the other lane.

More attractive barriers, like removable cement bollards, would allow bikes to go in and out of B while restricting cars, and be more attractive. Also these areas should be reconfigured so that there is a pull out area for cars, since people and trucks WILL stop there to unload along 2nd and 3rd, which currently causes congestion when crossing B along 2nd and 3rd. So we should make a pull out area veering into B for cars. . 1 147277 146982

This stretch of 25th between el camino and delaware is embarrassing for bike infrastructure. It is brand new and yet nothing is right! First off one of the traffic lanes should be a bike lane.

Secondly, there needs to be a crosswalk under the train line for peds (and I suppose bikes) to cross the street - expecting peds to walk to either end of the block to cross is unreasonable. I'd also love to see signs to discourage cars from simply stopping in the road to drop passengers - is it so hard to pull into the train station??? And lastly the bike racks should have been placed in a more convenient location at the train station... we need to make biking more convenient than driving, which entails locating bike racks in the best places! 4 147283 147207

Hi,

I would like to add my comment regarding the kids live on this block (Cypress Ave / Humboldt st.)
The school bus pick-ups are between 7-8am and drop-offs 12:30-5pm at 15 S. Humboldt st. which causes significant traffic stops on Humboldt street during the rush hours on the main street to get on/off hwy 101.

I live right next to the church and I frequently see drivers running the stop sign while kids are getting on/off the bus. The school bus driver yells at the kids to get on/off the bus and the road. It's not uncommon to hear the bus driver having a heated debate with the drivers ignoring the stop sign attached to the bus. The kids are excited to get off the bus, not paying much attention to the upcoming traffic assuming everyone just stops and wait for them to get off the road. The street vendors selling popsicles and sugary drinks right at the bus drop-off only makes the situaƟon more chaoƟc.

I honestly think the bus pick-up/drop off shouldn't be happening on the main street connecting the neighborhood with hwy 101 for the sake of safety and for preventing accidents from happening.

My quesƟons: Is there a plan to move this pick-ups/drop-offs to a more appropriate place?

Thank you,

Viktor

There is not a good way to get to Laurelwood park by bus. The 250 bus is the closest. Apple Maps says it’s a 12 minute walk, but it is uphill both ways, with hardly any shade. Not a good way to get to the park. Transit 1

A lot of of drivers speed, disregard red lights, stop signs and common sense altogether in this secƟon of Delaware Street.

We have had approximately 10-20 close calls over a period of 3 years, where distracted drivers have almost ran us over while we’re out walking our dog in the morning (7-8am) and evening (4-5pm) hours.

Some traffic cameras, policing, installation of speed bumps could help. Driving 1 147298
I’ve witnessed several close call accidents and near predestians due to illegal U turns on people trying to get parking spots. It is just a matter of time before an accident occurs due to these dangerous driving tactics. I would recommend doubling the fine and excessive enforcement to stop this maneuver which seems to occur everyƟme I am Downtown, which is almost daily. This occurs on 3rd and 4th Avenue between B Street and the El Camino. 1
147299 147009
I see this happen daily. People stop at E. Hillsdale at a red light. When it looks like no one is coming thru the intersection, they go up to the second intersection to make the right turn onto Hillsdale against the red.

There are traffic accidents constantly at this intersection. Some weeks there are 3 or 4 accidents. There is no protected turn so most of the accidents are the result of left turns.

Sometimes they also occur when one car stops to make a turn and another car runs into the back of the stopped car. It is a very dangerous intersection! Driving 0

The option I prefer and think is most pragmatic is to reduce the number of lanes on Franklin leading to Baze from both east and west. This is already done on the westbound approach, but it is "temporary". It should be permanent and the complementary eastbound lanes should be reduced to one starting some distance after Delaware. 0 147304

When City engineers changed this intersection to a two-lane right turn from Saratoga onto Hillsdale, they told the City Council they would include a flashing yellow arrow to alert drivers making the right turn to watch for and yield to pedestrians. This was never installed. Actually installing this warning arrow would help safety. Unfortunately the two-lane right design just favors motor vehicles over people walking. Not good. 0
147306
Bicyclists traveling east on Franklin basically lose the bike path when they reach the Police HQ.

They then have to move into the traffic lane to get across Saratoga and back onto a shared path at Kaiser. This is a pretty scary proposition. I see only the most intrepid cyclists doing it.

There needs to be a continuation of the shared path all the way across Saratoga. This would also work for westbound cyclists too, because the path is supposed to two-way.Bicycling 1 147307 146976
Agree. This is a bike boulevard in name only. It's not especially bike friendly. There is a share path on the north side of 28th for cyclists. Not very obvious tho. 2 147308 147156

As a bicyclist, you get here on Fashion Island and the path just ends.

Living nearby, I've heard and seen numerous car crashes, near misses (screeching tires) at this intersecƟon, generally because cars are speeding on Hillsdale.

I rarely, in my 30+ yrs of cycling in SM, cross over via the Hillsdale/101 overpass. It is suicidal.

The E-bound Hillsdale cars in right lane are turning right to get on to the S-101 ramp, then that lanes disappears and one had to content with cars turning right at the N-101 cloverleaf ramp

I remember one early morning when an Caltrans truck E-bound on Hillsdale, trying to get on to N 101 cloverleaf hit & killed a cyclist right at the entrance to the on-ramp.

I prefer the slightly safer 19th Avenue route. 2

This is an extremely dangerous intersection due to visibility challenges as parked cars make it impossible to see cross-traffic. A 4-way stop would make this much safer. 0 147355 147271
A 4-way stop would be a great improvement, especially due to the lack of parking enforcement of the red curbs. Cars tend to drive fast here due to the wide road but it's difficult to see cross traffic as there are constantly cars parked along the red curbs with seemingly no enforcement.

Either enforce the red curbs or make this a 4-way stop. 0 147358
Need more parking enforcement of red curbs. While the amount of red curbs is sufficient to allow for safe turns there are constantly cars parked in red that make it impossible to see the coming cross-traffic.

I agree. The road is too narrow to have cars parked on both sides, and people drive too fast along the road. This is unsafe for drivers, bicyclists, and pedestrians. I live on Tilton and see parked cars side swiped about three times per year in front of my house alone. Cars also regularly drive up onto the parkways to try to avoid getting side swiped, which detracts from the neighborhood aesthetics and also negatively impacts safety for pedestrians. I would love to see reduced speed limits, speed bumps, parking only permitted on one side, a dedicated bicycle lane along this road, and new/increased regulations and enforcement to reduce parking on parkways. 0

Please consider making all of Ellsworth and b street between 2nd and fourth street closed to vehicle traffic. This would reduce traffic incidents and allow for safer pedestrian walkways throughout the downtown. I’ve observed many near-crashes between cars and pedestrians as people try to turn, make U turns, and reverse to get a parking spot.

The 101 over-crossing is great, but headed westbound on a bike you're all of a sudden stuck at 3rd and Humboldt. There is no safe obvious way to continue along 3rd without crossing all lanes of traffic (to the outside "slow" lane of 3rd).

This crosswalk allows less than 10 seconds for pedestrians to cross 6 lanes of traffic across el camino. Literally (used correctly), every time I see someone crossing here they are either in the way of oncoming traffic or they're in imminent physical danger from cars turning from 25th onto NB el camino. I see a pedestrian have a cross call more than once a month. I was told 2+ years ago that this is a state route so the city can't change the crosswalk timing; that is irrelevant from a pedestrians point of view. I urgently needs adjustment.Walking 2 147504

This is *the most* dangerous part of my daily cross town bike commute (while carrying my daughter on my bike). Drivers through here are out of their minds with frustration because of slow traffic on el camino that they're avoiding, trying to beat lights, etc. And there is no bike at all! I would encourage local traffic only to parking garages, speed bumps, or other large changes to the traffic patterns here.

This street should be one-way between Humboldt and Delaware (or some substantial portion) to control traffic and improve pedestrian safety.

I bike along this route to and from the Hillsdale caltrain daily. There is no bike lane, and cars do not yield to cyclists at all coming on and off the highway.

This issue is BidirecƟonal.

I have had multiple instances where distracted drivers and speeding drivers have switched right in front of me.

The especially bad part is going north on delaware riding past the gas stations. The two right turn lanes make it very difficult for me to continue straight, as drivers will actively cut cyclists off or be siƫng in between two lanes.

As a pedestrian while waiting to cross Saratoga Dr at Park Pl, I see many cars run the red light for a right turn on red. Most drivers don't look for pedestrians and it feels like a tragedy waiting to happen. This intersection needs no right turn on red or enforcement of stopping before turning to be enforced.

When crossing Park Pl as a pedestrian, the crosswalks do not give enough time to cross the entire intersection. You often have to wait through 2 light cycles- one for each direction of Park Pl. 0

This intersection has been a complete mess ever since the (seemingly never to be finished) construction of Fremont Terrace began. The fence and food truck don’t help safety for cyclists 0

It would be nice to have speed bumps on W Hillsdale Blvd and a marked crosswalk here to make accessing Monterey St and the Creek Overlook Trail safer. Cars flying down the hill on W Hillsdale Blvd make this feel unsafe trying to look both ways to cross the street. Walking 0 147541 147476

This is a very dangerous intersection for cars on Poplar trying to get onto 101 S. 101 traffic exiting alters the sequence of cars trying to get on from Poplar and Amphlet. Drivers on Amphlett do not always stop and follow right of way trying to get onto 101.Driving 0 147544
This intersection is extremely busy and causes blockages for cars exiting 101. Traffic on Poplar trying to get on Humbolt are stuck in a long line of cars trying to get onto 101.

Weds street sweeping occurs in this neighborhood twice a month from 11-1 pm which coincides with the 12:25 and 12:35 pick up time for College Park Elementary. This creates a lot of additional congestion as neighborhood families and those doing pick up struggle to find parking.

If street sweeping can be adjusted to be done by 12, or after 12:35, it would alleviate congestion. 1

This street is pretty narrow in the morning and drivers going both directions have to wait and/or take turns passing by to go either direction. This is noticeable in the morning as there are a few schools in the area. 0

Change N. Eldorado, San Antonio, N. Fremont, and N. Grant to one way. Changing streets to one-way will help traffic flow through these narrow streets. Drivers get very aggressive on these streets trying to rush to next pinch point (where cars are parked on both sides) and try to get through pinch point instead of waiting for car coming in opposite direction. These streets are nearly impassable if garbage truck, school bus, or other large vechicle is driving towards you. Driving 0

To avoid the red light, Drivers heading east on Tilton Ave regularly cut through parking lot and then turn south onto San Mateo Drive. And often not stopping while driving out of parking lot.

I think this should be expensive traffic ticket (~$2000), the drivers are knowingly not following traffic laws Driving 0

For Poplar, driving NE (from ECR to 101), approaching the San Mateo Drive intersection, traffic backs up at the morning in the straight lane, but not in the left turn lane. Drivers who want to turn left will often travel into the oncoming traffic lane to get in front of the backup and make the left turn lane/light. This is extremely dangerous given the bike lane and volume of traffic here. There should be bollards on the center line to prevent drivers from doing this.Driving 0 147582
The Town of Hillsborough will be adding several dozen new units in Tobin Clark, next to CSM, as part of its housing element. I believe that new residents will drive via CSM.

There is a ChickFilA coming to Bridgepointe. Per the experience of Redwood City, there will be a huge amount of traffic generated. Much of this will be teenagers, who often aren't the best drivers.

There needs to be a crosswalk here for all of the Aragon HS students walking to school. It is unreasonable to ask them to walk that far to the next crosswalks in order to cross the street.

This comment is for the downtown as a whole. I regularly walk around downtown from my apartment and now that includes w my infant son in his stroller. The number 1 thing we could do to improve pedestrian and biking safety downtown is get rid of right in red. I cannot tell you how many times I have almost been hit by a driver turning right in red in Dan Mateo (and actually was hit once). It doesn’t matter if you have the crosswalk, it’s it’s broad daylight, if you’re walking w your 6†5†spouse who is in dayglow yellow, and a stroller that you’ve attached reflective tape a lights to, they will still act like they never saw you.

When I was 6 mo pregnant I was almost hit 5 times between Mounds Rd and Central Park - broad daylight, I always had the crosswalk light / 2x drivers never saw me (too busy looking for cars instead of pedestrians), 1 didn’t see me but their passenger did and screamed for them to stop and 2
Saw me in the crosswalk, made eye contact and still almost hit me bc it was more important for them to get were they were going faster than my safety.

Right on red is a failed experiment that study after study has shown leads to vastly increased pedestrian and cyclist injury and death. 0

This overpass would be improved greatly for bicyclists if they were grade-separated from 35mph+ car traffic. Instead they are at the same grade, while pedestrians on the sidewalk are above grade.

The speed cushions work, but only for the areas they are in. As soon as drivers get past them, they increase speed rapidly. They should be extended, probably up to Mason, and there should be regular patrol or speed traps in the afternoons on side streets. 1 147638
Fernwood, like all of the narrow streets north of 31st, is filled with students at school start and end times, frequent speeding, and there is low visibility at corners because students often park close to corners and driveways. Sideswipes are very common on Fernwood. Enforcement is an answer, so is possible signage or red curbs. 2

Sylvan receives speeders at high school start and end times. Students sometimes achieve 50mph on this narrow street - it is intermittent.

Suggest regular enforcement, and possible changes to the intersection at Fernwood, which can become impassible. Driving 3 147640
This intersection often gets drivers who do not yield to pedestrians at all. I once was walking to school with 4 children and a driver completely ignored the stop sign, came to a stop only when I yelled, and missed a child by only about 10 feet. I think the crosswalk should be raised. Again, once the speed bumps end, drivers immediately speed up until they get to Mason. Walking 1

The entire street should be highlighted for problems of visibility for drivers and pedestrians due to speeding and excessive parking - which is always better at the start of the school year, but gets worse as more students start driving throughout the year. Walking 0 147642 147211
I have seen a lot of speeding between 28th and 31st avenue. Switching to 2 lanes might work, but maybe if some left turn lanes were preserved so drivers from Sylvan, 30th, 29th, and others could enter Alameda from the opposite direction. The 2nd lane serves as a landing lane in this situation. But too much speeding overall - crossing as a pedestrian is frightening even at the official crosswalks. 0

I am dismayed that Hillsdale High School does not encourage, advertise, or allow students to park in this parking lot. Instead, they over-park in the neighborhood immediately to the north of the school. Students should be using this lot, and families should also drop off kids on Alameda (yes, and then walk for 3 minutes), rather than idling and inching along in the neighborhoods north of the campus for even longer periods of time just to get to a close drop off point.

Over the past several months, I've been concerned about pedestrian safety at the exits of the multiple parking towers, not just this one.

If you are walking up or down 31st avenue across Beverly, Landsdale, or any of the other streets, it is frightening because the young drivers that make up most of the drivers do not know to respect pedestrians (in addition to speeding). Possibly should have a crosswalk at every intersection in this area - that might remind the drivers to stay out of the intersection when pedestrians are present. Then you can also enforce this. Enforcement should be daily, by the way, not occasionally. 0

The high school is not asking its students to park on this section of 31st (same as the parking lot off Alameda), there are usually 20-30 open spots - instead, the students park in the neighborhood north of the school, affecting residents ability to drive and walk safely in the AM and afternoon. Yes it's a longer walk for students, but their convenience comes at the expense of our safety, and these spots sit empty. 0

Though the intersection is a 4-way stop, cars on Edison don't slow down much and visibility is bad coming in and out of the Hillsdale garage. Cars don't really expect people to be here and we've had a couple of near misses.

Technical Memorandum

INTRODUCTION
Kittelson & Associates, Inc. (“Kittelson”) is working with the City of San Mateo (“City”) to identify countermeasures to improve roadway safety performance as part of their Local Road Safety Plan (LRSP).

This memorandum summarizes the engineering and non-engineering treatments that could be implemented by the City to reduce crash frequency, severity, and risk throughout the City.

This memorandum begins with a discussion of engineering treatments/countermeasures identified for the City based on the crash patterns and trends analysis, as well as a review of characteristics at high priority intersections and roadway segments identified through the citywide network screening evaluation. This is followed by a discussion of potential education, enforcement, equity, and emerging technology strategies to partner with engineering countermeasures in working towards improving roadway safety performance across the City.

ENGINEERING TREATMENTS
This section presents engineering safety treatments identified to address citywide crash patterns and trends and potential emphasis areas as documented in the Crash Patterns and Trends Technical Memorandum.

The emphasis areas are identified based on the analysis of crash types, locations, movements, and behavioral factors and are considered in identifying the treatment groups in this stage of the LRSP development. These emphasis areas are as follows:
 Pedestrians and Bicyclists
 Intersections
 Improper Turning
 Driver Speed
 Alcohol and drug involvement
 Aging and young drivers

The treatments have been grouped into five treatment groups that most directly address the City’s crash patterns and trends for fatal and severe injury crashes, and overall crashes.

The five treatment groups identified include:

San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.
 Pedestrian Related Treatments
 Bicycle Related Treatments
 Signalized Intersection Treatments
 Unsignalized Intersection Treatments
 Roadway Segment Treatments

For each of these treatment groupings, priority countermeasures have been identified and summarized based on the crash types addressed, quantitative effectiveness of the treatment, and implementation considerations.

Pedestrian Related Treatments
Pedestrian related treatments were identified as one of the priority countermeasures for the City because pedestrian-involved crashes were overrepresented among fatal and serious injury crashes in the City.

Pedestrian-involved crashes make up nearly 36% of all fatal and severe injury crashes but only 9% of total crashes.

The following countermeasures were identified for potential application in San Mateo:
 Install Sidewalk/Pathway
 Crosswalk visibility enhancements
 Additional Pedestrian Crossing Improvements
a. Pedestrian Refuge Island

Install Sidewalk/Pathway
Description: Sidewalks and walkways provide people walking or rolling with a separated space to travel within the public right-of-way.

Purpose: Crash analysis patterns and trends for the City of San Mateo show that the third most frequently reported pedestrian action for total reported crashes and second most frequently reported pedestrian action for fatal/severe injury reported crashes was “In Road, including shoulder” (14% and 16%, respectively). According to the California LRSM, the presence of sidewalks on both sides of the street results in significant reductions in “walking along roadway” pedestrian crash risk compared to locations where no sidewalks or walkways exist.

Application: Per LRSM guidance document, this treatment may be considered for application under the following roadway context to be eligible for Highway Safety Improvement Program (HSIP) funding:
• Pedestrian and bicycle crashes have occurred within the limits of the new walkway; and, • An existing narrow sidewalk is not being replaced with a wider one.

Considerations: This treatment can be considered in locations with high pedestrian volumes, areas noted as not having adequate or no sidewalks, and a history of walking along roadway pedestrian crashes.

Systemic Application: Sidewalks are most likely to be integrated as part of larger capital improvement projects or installed as their own capital improvements. This treatment may be better suited as a spot treatment or a treatment package.

Crash Reduction Factor: 80% (California LRSM, 2020).

Planning Level Cost: Varies. The costs will vary depending upon factors such as sidewalk width, materials, and existence of curb, gutter, and drainage. Asphalt curbs and walkways are less expensive when compared to sidewalks but require more regular maintenance.

Crosswalk Visibility Enhancements
Description: This group of countermeasures includes high-visibility crosswalk markings, improved nighttime lighting, advance or in-street warning signage, curb extensions, and parking restrictions. For locations with unmarked crosswalks, lighting, curb extensions, and parking restrictions may be considered to improve sight distance and visibility of pedestrians. Figure 1 shows an example of a high-visibility pedestrian crosswalk treatment and Figure 2 shows an example of curb extensions combined with a raised crosswalk.

Figure 1: High-Visibility Crosswalk

Source: City of Sacramento, CA
Figure 2: Curb Extensions and Raised Crosswalk

Source: FHWA

Purpose: Analysis showed that the most frequently reported pedestrian action for total and fatal/severe injury crashes is “Crossing in crosswalk at intersection” (64% and 68%, respectively). Crosswalk visibility enhancements may be used to indicate preferred locations for people to cross, to increase visibility of the crossing location, and to help reinforce the driver requirement to yield the right-of-way to pedestrians at crossing locations.

Application: FHWA Field Guide recommends the following countermeasures at all established midblock or uncontrolled crosswalk locations:
• High-visibility crosswalk markings

242 of 337

February 10, 2023 Page 4
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.
• Overhead lighting
• On-street parking restrictions or curb extensions

Additionally, adding advance Yield Here to Pedestrian sign and yield line should be considered for the following roadway combinations of average daily traffic (ADT), number of travel lanes, and posted speed limit conditions:
o Any ADT + 4 or more lanes (with or without a raised median) + any posted speed limit o Any ADT + any number of lanes + ≥ 35 mph posted speed limit Per FHWA Field Guide, on roadways with 4 or more lanes and more than 9,000 vehicles per day, the risk for pedestrian crashes could increase if uncontrolled marked crosswalks are not combined with other treatments, such as refuge islands or Pedestrian Hybrid Beacons.

Considerations: These treatments may help address most traffic behaviors or safety issues but are most needed when the following conditions are observed at the site:
• Drivers not yielding to pedestrians in crosswalks
• Inadequate conspicuity/visibility of the crosswalk and pedestrian • Noted conflicts at crossing locations.

Systemic Application: Low-cost crosswalk visibility enhancements may easily be integrated into other ongoing maintenance or capital improvement projects. This could include integration into routine restriping or resurfacing activities. Markings would likely have to be redone on a regular basis, which may increase maintenance costs.

Crash Reduction Factor: 25 - 40% depending on the treatments selected.

Planning Level Cost: Varies - $5,000 – 20,000 depending on the treatments selected.

Additional Pedestrian Crossing Improvements
Pedestrian Refuge Island
Description: A pedestrian refuge island is a median with a dedicated separated space for pedestrians to protect pedestrians who are crossing the street. This countermeasure is also referred to as a crossing island or pedestrian island. Figure 3 shows an example of a pedestrian refuge island treatment.

Purpose: Analysis showed that the 11% of the total pedestrian crashes are “Crossing not in crosswalk” and the most frequently reported pedestrian action for total and fatal/severe injury crashes is “Crossing in crosswalk at intersection” (64% and 68%, respectively). These treatments are add-ons to address these pedestrian-related crashes and to address issues discussed earlier in this section. Refuge islands allow pedestrians a place for refuge during multiple-stage crossings and to focus on identifying adequate gaps in traffic for one direction of vehicular travel to cross at a time. This treatment also reduces the crossing distance for pedestrians. Refuge island also positions crossing pedestrians in the sightline of drivers approaching the intersection, potentially reducing conflicts.

Application: Per FHWA Field Guide, refuge islands may be considered under the following roadway conditions:
• Any ADT + 2 or 3 lanes (without a raised median) + any posted speed limit

243 of 337

February 10, 2023 Page 5
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.
• ADT ≥ 9,000 + 4 or more lanes (without a raised median) + any posted speed limit • Any ADT + 4 or more lanes (without a raised median) + ≥ 35 mph posted speed limit

Figure 3: Pedestrian Refuge Island

Source: NACTO

Considerations: This countermeasure is most effective where the following are observed at the site:
• Inadequate conspicuity/visibility of the crosswalk and/or crossing pedestrian • Excessive vehicle speeds or traffic volumes
• Insufficient pedestrian separation from traffic during long crossings

Systemic Application: Raised concrete medians are most likely installed as their own capital improvement projects and are usually installed in conjunction with a marked crosswalk and warning sign. Interim crossing islands can be implemented systemically using flexible delineators and temporary curbing.

Crash Reduction Factor: 45% (California LRSM, 2020).

Planning-Level Cost: $2,000 - $41,000 per island, depending on the length of the island (the average cost of the island is $13,500 with an average cost per square foot of $10). The costs for concrete islands will be higher than for asphalt islands, though the lifespan of concrete is longer when compared to the lifespan of asphalt. 
Rectangular Rapid Flashing Beacons (RRFBs)
Description: Rectangular Rapid Flashing Beacons (RRFB) include pedestrian-activated flashing lights and additional signage that enhance the visibility of marked crosswalks and alert motorists to pedestrian crossings. They use an irregular flash pattern that is similar to emergency flashers on police vehicles. RRFBs may be installed at unsignalized intersections and at mid-block pedestrian crossings. Figure 4 shows an example of a RRFB treatment.

Figure 4: Rectangular Rapid Flashing Beacons

Source: Texas A & M Transportation Institute

Purpose: RRFBs have been shown to significantly increase driver yielding behavior at uncontrolled crosswalks, with motorist yielding rates ranging from 34% to over 90% (NCHRP, 2020). This treatment helps reduce pedestrian-vehicle conflicts and increases the visibility of pedestrian crossing locations.

Application: Per FHWA guidance, RRFBs may be considered for the below conditions:
• ADT ≤ 15,000 + 2 lanes or one lane in each direction with a raised median + ≥ 40 mph posted speed limit
• ADT 9,000 – 15,000 + one lane in each direction with or without median + ≥ 35 mph posted speed limit
• Multilane (more than one lane in each direction) with <40 mph posted speed limit

Considerations: This treatment may be considered for potential RRFB installation locations:
• RRFBs shall not be used without the presence of a pedestrian crossing sign. • An RRFB should be installed in the median rather than the far-side of the roadway if there is a pedestrian refuge or other type of median.
• Advance yield pavement markings and signs may be used to supplement RRFBs. • Solar-power panels can be used to eliminate the need for a power source. • Other treatments may be more appropriate in locations with sight distance constraints.

Systemic Application: RRFBs are mostly likely to be integrated as part of larger capital improvement projects or installed as their own capital improvements. This treatment may be better suited as a spot treatment or a treatment package.

Crash Reduction Factor: 35% (California LRSM, 2020).

245 of 337

San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Planning Level Cost: $4,500 to $52,000 each, with the average cost estimated at $22,250. These costs include the complete system installation with labor and materials.

Pedestrian Hybrid Beacons (PHBs)
Description: A Pedestrian Hybrid Beacon (PHB) is a traffic control device that uses beacons to control traffic when activated. PHBs are used to control traffic and revert to all dark until a pedestrian activates it via a push button or other form of detection. When activated, the beacon displays a sequence of flashing and solid lights that indicate when vehicles must stop and when pedestrians should cross. Figure 5 shows an example of a Pedestrian Hybrid Beacon.

Figure 5: Pedestrian Hybrid Beacon

Source: City of San Luis Obispo, CA

Purpose: PHBs provide active warning to drivers and control their movements when a pedestrian is in the crosswalk. PHBs have been shown to significantly increase driver yielding behavior at uncontrolled crosswalks, with motorist yielding rates exceeding 90% (FHWA 2014). These devices have been successfully used at school crossings, parks, senior centers, mid-block crossings, and other pedestrian crossings on multilane or higher-speed streets.

Application: Per FHWA guidance, PHBs may be considered in the following conditions:
• AADT of at least 15,000 + 4 or more lanes + any speed limit • AADT of at least 9,000 + 3 or more lanes (with or without median) + ≥ 35 mph speed limit • Any AADT + any number of lanes + ≥ 40 mph speed limit Considerations: This treatment may be considered when the following factors are observed on site:
• Long pedestrian delay due to few available gaps in traffic • Drivers not yielding to pedestrians in crosswalks
• Noted vehicle-pedestrian conflicts at crossing locations.

Systemic Application: PHBs are most likely installed as their own capital improvement projects.

Crash Reduction Factor: 15 - 69% (California LRSM, 2020).

Planning Level Cost: $21,000 - $128,000 with an average per unit cost of $57,680.

Signalized Intersection Pedestrian Treatments
Description: This group of treatments include strategies for enhancing pedestrian crossings at signalized intersections, including: implementing leading pedestrian intervals, prohibiting right-turns on red, pedestrian countdown signal heads, and pedestrian scramble. Each of these strategies is summarized below:
• Leading Pedestrian Interval (LPI): A leading pedestrian interval (LPI) gives pedestrians the opportunity to begin crossing 3-7 seconds before vehicles are given a green indication. With this head start, pedestrians can better establish their presence in the crosswalk before vehicles have priority to turn left to increase their visibility and reduce potential conflicts. • No Right-Turn on Red (no RTOR): This treatment restricts motorists from turning right during a red phase. The posting of “No Turn on Red” signs (static or dynamic) may be posted to restrict these turns, according to the specifications set forth in the California Manual on Uniform Traffic Control Devices (CA MUTCD). Dynamic signs may be used to restrict right turns during certain times of day or during certain signal phases.
• Pedestrian Countdown Signal Heads: A pedestrian countdown signal contains a timer display and counts down the number of seconds left in the crossing phase. Countdown signals can reassure pedestrians who are in the crosswalk when the flashing "DON’T WALK" interval appears that they still have time to finish crossing. Countdown signals may begin counting down either when the "WALK" or when the flashing "DON’T WALK" interval appears and stop at the beginning of the steady "DON’T WALK" interval. Figure 6 shows an example of a pedestrian countdown signal head.

• Pedestrian Scramble: Pedestrian scramble (also known as Barnes Dance) is a form of the pedestrian “WALK” phase at a signalized intersection in which all vehicular traffic is stopped, allowing pedestrians to safely cross through the intersection in all directions simultaneously, including diagonally. Figure 7 shows an example of a pedestrian scramble treatment.

Figure 7: Pedestrian Scramble
Source: Virginia Department of Transportation (VDOT)
Purpose:
• LPIs increase visibility of crossing pedestrians and reduce conflicts between pedestrians and vehicles. This treatment increases the likelihood of motorists yielding to pedestrians because pedestrians are in the crosswalk by the time traffic signal turns green for parallel vehicle movements3.
• No RTOR eliminates conflicts between right-turning vehicles and pedestrians and bicyclists traveling through.
• Pedestrian countdown signal heads have been shown to encourage more pedestrians to use the pushbutton rather than cross against the signal. These countdown signals provide information to pedestrians about the amount of time remaining to safely cross the street at signalized intersections.
• A pedestrian scramble reduces conflicts between vehicles and pedestrians and improves pedestrian access and safety.

Application: Per NCHRP guidance document4, the following treatments may be considered for application under the following roadway contexts:
• LPIs and No RTOR treatments may be considered at signalized intersections with medium to high motor vehicle turning volumes and pedestrian volumes.
• Pedestrian countdown signal heads may be considered at any signalized intersections where they do not exist. These can be prioritized to locations used by mobility-challenged, elderly pedestrians, or adults accompanying small children.
• Pedestrian scramble may be considered at intersections where pedestrian volumes outnumber vehicular volumes.

Systemic Application: LPIs and pedestrian countdown signal heads are better suited as systemic treatments in areas where there are existing pedestrian signals and high volumes of pedestrians and turning vehicles.

No RTOR may be implemented as a systemic treatment, paired with a solution to address higher right-turn on green needs, if needed. Pedestrian scrambles are typically implemented as spot treatments or a treatment package in areas with very high pedestrian activity.

Crash Reduction Factor: LPI – 59%; No RTOR – 25%; Pedestrian Countdown Signal Heads – 25%; Pedestrian scramble – 40%
Planning-Level Cost: LPIs: $550 - $6,000, including countdown timer, controller, signal head and software upgrade; No RTOR: $200 - $6,000 depending on the type of sign (electronic vs. others); Pedestrian countdown signal heads: $190 - $1,930; Pedestrian scramble: $5,000 - $15,000 depending on signal timing modifications and pavement markings.

Bicycle Related Treatments
Bicycle-related treatments were identified as one of the priority countermeasures for the City because bicyclist-involved crashes were overrepresented as compared to other crash types among fatal and serious injury crashes in the City. Bicyclist-involved crashes are 6% of total crashes but account for 19% of the total fatal and severe injury crashes in the City.

The following countermeasures were identified in bicycle related treatments:
 Install bike lanes
 Extend bike lanes through intersection
 Road diets (Reduction of vehicle travel lanes)
 Install advance stop bar before crosswalk (Bike boxes)  Install bicycle signal heads
The information provided in the sections below is adapted from the Federal Highway Administration (FHWA) Safety Guide and Countermeasure Selected System (FHWA BIKESAFE)5 and National Cooperative Highway Research Program (NCHRP) Guidance to Improve Pedestrian and Bicyclist Safety at Intersections (NCHRP, 2020), National Association of City Transportation Officials (NACTO) Urban Bikeway Design Guide (NACTO, 2011)6 and California Local Roadway Safety Manual (California LRSM).

Install Bike Lanes
Description: This treatment designates a portion of roadway for the preferential or exclusive use of bicyclists through striping, signage, and pavement markings. Bike lanes typically run in the same direction of traffic, though they may be configured in the contra-flow direction on low-traffic corridors for the connectivity of a particular bicycle route. Different types of bike lanes are as follows:

• Conventional Bike Lanes: These bike lanes designate an exclusive space for bicyclists using pavement markings and signage. These are located adjacent to motor vehicle travel lanes and flow in the same direction as motor vehicle traffic.
• Buffered Bike Lanes: These bike lanes are conventional bike lanes paired with a designated buffer space separating the bike lane from motor vehicle travel lanes and/or parking lane. Figure 8 shows an example of a buffered bike lane.
• Contra-Flow Bike Lanes: These bike lanes allow bicyclists to ride in the opposite direction of motor vehicle traffic. They convert a one-way street into a two-way street: one direction for motor

San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.
vehicles and bikes, and the other for bikes only. Figure 9 shows an example of a contra-flow bike lane.
• Left-Side Bike Lanes: These bike lanes are conventional bike lanes placed on the left-side of one- way streets or two-way median divided streets. Figure 10 shows an example of a left-side bike lane.

Purpose: Bike lanes provide separation from vehicular traffic, and help bicyclists to ride at their preferred speed without interference from prevailing traffic conditions. They also facilitate predictable behavior and movements between bicyclists and motorists and reduces potential conflicts between motorists and bicyclists.

Application: Per the NACTO Urban Bikeway Design Guide, the following treatments may be considered for application under the following roadway contexts:
• Conventional Bike Lanes: ADT ≥ 3,000 + ≥ 25 mph posted speed limit + high transit vehicle volumes • Buffered Bike Lanes: ADT ≥ 3,000 + ≥ 35 mph posted speed limit • Contra-Flow Bike Lanes: On streets where bicyclists are already riding the wrong way, and on low- speed and low volume streets
• Left-Side Bike Lanes: ADT ≥ 3,000 + ≥ 35 mph posted speed limit + one-way or median divided streets + frequent transit stops or loading zones on right side of street.

Considerations: These treatments may be considered when any of the following factors are observed on site:
• Presence of sidewalk or wrong-way riding behavior by bicyclists; • Limited connectivity and access to bicyclists; or,
• Presence of right or left-turning conflicts between bicyclists and motor vehicles at intersections and/or driveways.

Systemic Application: Low-cost bike lane installations may easily be integrated into other ongoing maintenance or capital improvement projects, provided it involves striping the roadway and minor signing.

This could include integration into routine restriping or resurfacing activities. Bikeway projects that require roadway widening, right-of-way acquisition and environmental impacts are most likely addressed as capital improvement projects given the increased cost and complexity of these improvements.

Crash Reduction Factor: 35 - 45% depending on the treatments selected.

Planning-Level Cost: Varies – approximately $55,000 per 100 feet, depending on treatments selected and existing roadway configuration.

Extend Bike Lanes through Intersection
Description: Bicycle pavement markings through intersections indicate the intended path of bicyclists through an intersection or across a driveway or ramp. They guide bicyclists on a safe and direct path through the intersection and provide clear boundary between paths of bicyclists and motorists. Figure 11 shows an example of bicycle pavement markings through intersections.

Purpose: Crash patterns analysis for the City of San Mateo shows that the most frequently reported crash type for total and fatal and severe injury bicyclist-involved crashes is broadside crashes (48% and 32% respectively). The use of bicycle pavement markings through intersections helps raise awareness for both bicyclists and motorists to potential conflict areas. This treatment also reinforces that the through bicyclists have priority over turning motor vehicles.

Application: Per the NACTO Urban Bikeway Design Guide, bicycle pavement markings may be considered for application at particularly wide or complex signalized intersections, where the bicycle path may be unclear.

Figure 11: Bike Lane markings through intersections

Source: Maricopa Association of Governments

Considerations: This treatment may be considered when any of the following factors are observed:
• Presence of right or left-turning vehicle conflicts with through bicyclists; or, • Locations with bicycle lanes or separated bike lanes where it is desired to delineate the bicycle crossing;
Since the effectiveness of markings depends entirely on their visibility, maintaining markings should be a high priority where this treatment is considered.

Systemic Application: Bicycle pavement markings are mostly likely to be integrated as part of larger capital improvement projects along major bike routes. This treatment may be better suited as a treatment package in urban neighborhoods.

Crash Reduction Factor: 39% (ODOT, 2021)

252 of 337

February 10, 2023 Page 14
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Planning-Level Cost: Varies. $200 - $5,000 per intersection depending on surface area of markings, materials used, and the color of markings.

Road Diets (Reduction of Vehicle Travel Lanes)
Description: Road diets reduce the number of travel lanes on the roadway and provide space to implement pedestrian and bicyclist related treatments, including adding bike lanes and median crossing islands. The most common road diet configuration involves converting a four-lane roadway into three travel lanes (with one lane in each direction and a two-way center-turn lane to facilitate turning movements), often supplemented with bike lanes, pedestrian refuge islands, and crosswalk visibility enhancements.

Figure 12 shows an example of a road diet i.e., reconfiguration of a roadway.

Purpose: From the crash patterns analysis for the City of San Mateo:
• Head-on crashes comprise 16% of the fatal and severe injury bicyclist-involved crashes; • Unsafe motor vehicle speed is the most frequently reported primary crash factor for fatal and severe injury bicyclist-involved crashes (26%) and is the third most frequently reported primary crash factor for total bicyclist-involved crashes (10%); • Walking in Road – including shoulder, crossing not in a crosswalk and crossing in a crosswalk not at an intersection are among the most frequently reported pedestrian actions for pedestrian- involved crashes.

Road Diets are intended to improve access management, increase pedestrian and bicyclist access, and enhance roadway safety. Studies indicate a 19 to 47 percent reduction in overall crashes when a Road Diet is installed on a previously four-lane undivided facility as well as a decrease in crashes involving drivers under 35 years of age and over 65 years of age7. Road Diets can reduce the vehicle speed differential, which can reduce the number and severity of crashes8.

Figure 12: Road Diet

Source: FHWA
Application: Per the NCHRP Guide, road diets may be considered for application for the following contexts:
• At priority pedestrian and bicycle routes; or,

San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.
• In urban and suburban areas with multilane roadways that are designed for vehicle throughput rather than multiple modes of travel.

Considerations: This treatment may be considered when any of the following factors are observed on site:
• Presence of left-turning conflicts between bicyclists and motor vehicles; or • Desire to better accommodate pedestrians and bicycle traffic.

Systemic Application: Road diets are most likely addressed as their own capital improvement projects and are usually installed in conjunction with bicycle lanes and/or a pedestrian refuge island. However, they may be implemented as part of resurfacing or other minor capital improvement projects where restriping and minor signs are the only elements needed for the road diet implementation.

Crash Reduction Factor: 26 - 43%
Planning-Level Cost: Varies. $25,000 - $40,000 per mile, depending on context and configuration.

Bike Box
Description: A bike box is a designated area at the head of a traffic lane at a signalized intersection that provides bicyclists with a safe and visible way to get ahead of queuing traffic during the red signal phase.

Figure 13 shows an example of a bike box.

Figure 13: Bike Box

Source: NACTO
Purpose: Crash patterns analysis for the City of San Mateo shows that:
• Broadside crashes are the most frequently reported crash type for total and fatal and severe injury bicyclist-involved crashes (48% and 32% respectively).
• Automobile right of way is the second most frequently reported primary crash factor for bicyclist- involved crashes.

The use of bike boxes increases visibility of bicyclists and helps prevent “right-hook” or “left-hook” conflicts with turning vehicles at the start of the green indication. In addition to increasing the visibility of bicyclists, bike boxes provide priority for bicyclists by allowing them to come to the front of a queue.

254 of 337

February 10, 2023 Page 16
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Application: Per the NACTO Urban Bikeway Design Guide, bike boxes may be considered for application at signalized intersections with high volumes of bicyclists and/or motor vehicles, especially those with frequent bicyclist left-turns and/or motorist right-turns.

Considerations: This treatment may be considered when any of the following factors are observed on site:

• Presence of right- or left-turning conflicts between bicyclists and motor vehicles; • Desire to accommodate left-turning bicycle traffic;
• A situation where the dominant motor vehicle traffic flows right and bicycle traffic continues through (such as a Y intersection or access ramp).

Systemic Application: Bike Boxes are most likely to be integrated as part of capital improvement projects along major bike-routes. This treatment may be better suited as a treatment package in urban neighborhoods.

Crash Reduction Factor: 35% (ODOT, 2021)
Planning-Level Cost: $5,000 per box, including green thermoplastic, pavement markings and signage.

Install Bicycle Signal Heads
Description: Bicycle signal heads are an additional traffic-control device installed at signalized intersections to provide guidance and right-of-way control to bicyclists in specific circumstances. Figure 14 shows an example of a bicycle signal head.

Figure 14: Bicycle Signal Head

Source: NACTO

Purpose: Bicycle signal heads may be used to improve safety and operations at signalized intersections where bicycles require specific guidance.

Applications: Bicycle signal heads may be considered for application under the following contexts:
• At intersections with bicycle-specific movements such as contraflow bike lane or separated bike lanes where bicycle-specific control is required
• At intersections where bicycle movements need to be separated in time from a conflicting vehicular movement, such as locations with a high volume of left- or right-turns • At intersections with high bicycle volumes where bicyclists would otherwise follow the pedestrian indication (such as shared-use path crossings) or vehicular indication Considerations: This treatment may be considered when any of the following factors are observed on site:

• Presence of intersections where a bicycle facility transitions from a cycle track to a bicycle lane; or, • Locations with highly used bicycle route that must cross a major signalized intersection to connect users to the rest of the route.

255 of 337

February 10, 2023 Page 17
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Systemic Application: Bike signals are better suited as a spot or corridor treatment at intersections that are complicated for bicyclists to navigate, intersect a primary bicycle route, and have high bicycle volumes.

This treatment may be used as a treatment package in cases where agencies want to create a “green wave” effect by timing bicycle signals along the corridor to allow bicyclists to move through intersections at a consistent speed.

Crash Reduction Factor: 45% (ODOT, 2021)

Planning-Level Cost: Varies. $1,000 per signal face and increases with the number of signal heads and bicycle detection required.

Signalized Intersection Treatments
Crashes within the influence area of a signalized intersection represent 28% of total crashes and 39% of fatal and severe injury crashes in the City of San Mateo. Reducing conflicts with non-motorists, right angle, and rear-end crashes, crashes during dusk/dawn and dark without street lighting have been identified as priority areas for signalized intersection treatments in San Mateo. The countermeasures in this section seek to improve the visibility of the intersection and reduce the potential for conflicting movements within the intersection.

The following treatments were identified for signalized intersections in the City of San Mateo:
 Install intersection lighting
 Improve signal hardware
 Provide advanced dilemma zone detection
 Install left-turn lane and add turn phase (signal has no left-turn lane or phase before)  Provide protected left-turn phase (left turn lane already exists) The information provided in the sections below is adapted from FHWA Signalized Intersections:

Informational Guide9, California Local Roadway Safety Manual (California LRSM) and current research.

Install Intersection Lighting
Description: This treatment involves adding intersection lighting to improve safety during nighttime conditions.

Purpose: In the City of San Mateo, 32% of fatal and severe injury pedestrian-involved crashes occurred in the evening when it is dark, and 14% of fatal and severe injury bicyclist-involved crashes occurred when it is dark. Providing intersection lighting improves safety during nighttime conditions by:
• Making drivers more aware of their surroundings, which improves perception-reaction times; • Enhancing drivers’ available sight distances to perceive roadway and intersection characteristics in advance of the change; or
• Improving non-motorists’ visibility and navigation.

Application: This treatment may be considered at locations with crashes that may indicate that night-time drivers are unaware of the roadway characteristics.

256 of 337

February 10, 2023 Page 18
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Considerations: This treatment may be considered at intersections with disproportionate number of night- time crashes and do not currently have lighting at the intersection or on its approaches.

Systemic Application: This treatment may be implemented to upgrade intersections that have experienced nighttime crashes and have no or limited lighting. New signal or signal modifications should consider installing adequate street lighting as a proactive measure to prevent crashes.

Crash Reduction Factor: 20 - 74%
Planning- Level Cost: $7,000 to $10,000 per light
Improve Signal Hardware
Description: This treatment involves installing new LED lighting, signal back plates, retro-reflective tape outlining the back plates, or additional signal heads to increase signal visibility.

Purpose: Providing better visibility of intersection signals aids drivers’ advance perception of the upcoming intersection. Visibility and clarity of the signal should be improved without creating additional confusion for drivers.

Application: This treatment may be considered at signalized intersections with a high frequency of broadside and rear-end crashes.

Considerations: This treatment is a human factors enhancement of a traffic signal’s visibility, conspicuity, and orientation for all drivers. This treatment may also improve intersection awareness during periods of power outages or during evening and night conditions, when the signals would otherwise be dark, providing a visible cue for drivers to stop at the intersection ahead.

Systemic Applications: Due to the low cost of this treatment, it may be implemented systemically throughout the city.

Crash Reduction Factor: 0 – 46%
Planning-Level Cost: $1,500 to $3,000 per signal head
Provide Advanced Dilemma Zone Detection
Description: The Advanced Dilemma-Zone Detection system enhances safety at signalized intersections by modifying traffic control signal timing to reduce the number of drivers that may have difficulty deciding whether to stop or proceed during a yellow phase. This system uses pulse (or advanced) detectors placed at one or more locations on the intersection approach to extend the green phase and prevent the onset of yellow while approaching vehicles are in the dilemma zone. Figure 15 shows an example of an Advanced Dilemma Zone Detection System.

Purpose: This treatment may reduce rear-end crashes associated with unsafe stopping and angle crashes due to illegally continuing into the intersection during the red phase. Advanced dilemma-zone detection uses the speed, location, and length of vehicles to calculate the location of the dilemma zone relative to both vehicle speeds and their intersection approach.

Figure 15: Advanced Dilemma Zone Detection System

Source: FHWA

Application: This treatment may be applied at intersections that have a high frequency of broadside and rear-end crashes.

Considerations: Installation costs should be low and the time to implement short. Additional modifications to the traffic signal controller may also be necessary.

Systemic Applications: This treatment can be very effective as a systemic approach. Video detection equipment is now available for this purpose, making installation and maintenance more efficient and cost effective.

Crash Reduction Factor: 39%

Planning-Level Cost: $25,000 to $30,000 per system. If a system is already in place, signal timing updates would be $5,000 - $8,000.

Install left-turn lane and add turn phase (signal has no left-turn lane or phase before)
Description: Provides exclusive left-turn lanes and appropriate signal phasing for left-turning vehicles.

Purpose: Left-turn lane allows separation of left-turn and through-traffic streams, thus reducing the potential for rear-end crashes. Left-turn phasing also provides a safer opportunity for drivers to make a left-turn. The combination of left-turn storage and a left turn signal has the potential to reduce many crashes between left-turning vehicles and through vehicles and/or non-motorized road users.

Application: Left-turn lanes may be considered at intersections which have difficulties in accommodating left-turning vehicles and have high angle, rear-end, and sideswipe crashes.

According to the FHWA Signalized Intersections: Informational Guide, left turn phasing may be applied at intersections under the following contexts:

• The left-turning movement crosses 3 or more lanes of opposing through traffic • The posted speed of opposing traffic exceeds 45mph
• A minimum of 2 left-turning vehicles per cycle and the product of opposing and left-turn hourly volumes exceeds

258 of 337

February 10, 2023 Page 20
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.
o Random arrivals (no other traffic signals within 0.5 miles): One opposing lane – 50,000 vehicles per hour and two opposing lanes – 90,000 vehicles per hour o Platoon arrivals (other traffic signals within 0.5 miles): One opposing lane – 50,000 vehicles per hour and two opposing lanes – 90,000 vehicles per hour

Considerations: Left-turn lanes increase the capacity of the approach by adding an additional approach lane; they allow for a wider variety of phasing options. On the other hand, left-turn lanes may increase the overall intersection cycle length, adding delay to all users.

Crash Reduction Factor: 17 – 58%

Planning-Level Cost: Varies. $25,000 – $200,000 per approach for restriping the left-turn lane and adding left-turn phase.

Provide Protected left-turn phase (left-turn lane already exists) Description: The protected left turn phase provides a green arrow for left turning vehicles while stopping both on-coming traffic and parallel pedestrian crossings to eliminate conflicts.

Purpose: A properly timed protected left-turn phase can help reduce rear-end and sideswipe crashes between left-turning vehicles and the through vehicles as well as vehicles behind them and reduce conflicts with pedestrians crossing parallel to vehicular traffic.

Application: This treatment may be considered in the following contexts:
• The pedestrian and bicyclist crossing phase often conflicts with left-turn maneuvers • Providing protected left-turn phases can significantly improve the safety for left-turn maneuvers by removing the need for the drivers to navigate through gaps in oncoming/opposing through vehicles.

Considerations: Protected left-turn phases are warranted based on factors such as turning volumes, delay, visibility, opposing vehicle speed, distance to travel through the intersection, presence of non-motorized road users, and safety experience of the intersections. Protected left-turn phasing may reduce intersection capacity or require longer lengths and may impact signal system coordination.

Systemic Application: Adding a protected left-turn phase where a left-turn currently exist may be implemented systemically at signalized intersections or integrated with capital improvements at the signal due to the limited needs for the additional phase (adjusting signal timing and dedicated left-turn signal heads).

Crash Reduction Factor: 16 – 99%
Planning-Level Cost: Adjusting signal phasing/timing is very low cost. New signal equipment can range from $8,000 to $150,000 depending on what materials are needed.

Unsignalized Intersection Treatments
Crashes within the influence area of an unsignalized intersection represent 65% of total crashes and 54% of fatal and severe injury crashes in the City of San Mateo. From the crash patterns analysis for the City of San Mateo, reducing conflicts with non-motorists, improper turning, rear-end crashes, unsafe speed, crashes during dusk/dawn and dark without street lighting are identified as priority areas for unsignalized intersections’ treatment. The countermeasures suggested in this section seek to improve the visibility of the intersection, reduce the potential for conflicting movements within the intersection, thereby reducing the number of conflict points within the influence area of the intersection.

The following treatments were identified for unsignalized intersections in the City of San Mateo:
 Install intersection lighting
 Convert to all-way STOP control (from 2-way or Yield control)  Install roundabouts
 Install or upgrade intersection signage and/or pavement markings  Improve sight distance to intersection (clear sight triangles)  Install right turn/left-turn lane
 Create directional median openings to allow (and restrict) left-turns and U-turns Install Intersection Lighting
Description: This treatment involves adding intersection lighting to improve safety during nighttime conditions.

Purpose: In the City of San Mateo, 32% of fatal and severe injury pedestrian-involved crashes occurred in the evening when it is dark, and 14% of fatal and severe injury bicyclist-involved crashes occurred when it is dark. Providing intersection lighting improves safety during nighttime conditions by:
• Making drivers more aware of their surroundings, which improves perception-reaction times; • Enhancing drivers’ available sight distances to perceive roadway and intersection characteristics in advance of the change; or
• Improving non-motorists’ visibility and navigation.

Application: This treatment may be considered at locations with crashes that may indicate that night-time drivers are unaware of the roadway characteristics.

Considerations: This treatment may be considered along unsignalized intersection approaches with disproportionate number of night-time crashes and do not currently have lighting at the intersection or at its approaches.

Systemic Application: This treatment may be implemented to upgrade the City’s existing unsignalized intersections that have experienced nighttime crashes.

Crash Reduction Factor: 20 - 50%

Planning- Level Cost: $7,000 to $10,000 per light

260 of 337

February 10, 2023 Page 22
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Convert to all-way STOP control (from 2-way or Yield control) Description: STOP sign at intersection approaches warns drivers to slow down and prepare to stop.

Purpose: All-way stop control can reduce broadside and improper turning crashes at unsignalized intersections by providing more orderly movement at an intersection, reducing through, and turning speeds, and minimizing the safety effect of any sight distance restrictions that may be present.

Application: This treatment may be considered at unsignalized intersections that have broadside and improper turning crashes and have no controls on major roadway approaches.

Considerations: All-way stop control is suitable only at intersections with moderate and relatively balanced volume levels on the intersection approaches. Under other conditions, the use of all-way stop control may create unnecessary delays and aggressive driver behavior. This countermeasure only applies to crashes occurring in the intersection and/or influence area of the new control. California MUTCD warrants must always be followed.

Systemic Application: This treatment may be implemented as a systemic approach but is most often implemented as a spot treatment.

Crash Reduction Factor: 50%
Planning-Level Cost: Varies. $500 per sign which does not include the installation cost.

Install Roundabouts
Description: This treatment consists of installing a roundabout as traffic control at an intersection. A roundabout is a type of circular intersection without traffic signals or stop signs, where drivers travel counterclockwise around a center island. When entering the roundabout, drivers yield to existing traffic, then enter the intersection and exit in their desired direction. Figure 16 shows an example of a roundabout.

Figure 16: Roundabout

Source: FHWA
Purpose: Roundabouts are designed to eliminate left turns by requiring traffic to exit to the right of the circle. Roundabouts are installed to manage vehicular speeds through the intersection, improve safety at

261 of 337

February 10, 2023 Page 23
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.
intersections by eliminating broadside and head-on crashes, reducing the severity of crashes, and helping the traffic to flow more efficiently.

Application: This treatment may be considered at any intersection with a high frequency of reported crashes, traffic delays, complex geometry (more than four approach roads), frequent left-turns, and/or relatively balanced traffic flows.

Considerations: Roundabouts work well for intersections with low-to-moderate traffic speeds, and lower traffic volumes. Per NCHRP 672 Roundabouts: Informational Guide, typical daily service volume on 4-leg single lane roundabouts is 25,000 vehicles/day and on 4-leg two-lane roundabouts is 45,000 vehicles/day.

Systemic Application: Due to the need to design roundabouts for the context of each location, this treatment is best implemented as part of a site-specific capital improvement.

Crash Reduction Factor: 12 - 78%
Planning-Level Cost: $45,000 - $500,000 depending on the size, site conditions, and right-of-way acquisition and needs.

Install or upgrade intersection signage and/or pavement markings Description: This treatment consists of adding or upgrading signage and pavement markings at and on the approach to an unsignalized intersection. This can include advance intersection warning signs, STOP AHEAD pavement markings, transverse rumble strips on the approach, stop bars, and upgraded warning or control signs.

Purpose: This treatment is particularly suited for unsignalized intersections with patterns of rear-end, broadside, and turning-related crashes that occurred due to lack of driver awareness of the presence of the intersection. Unsignalized intersections that are not clearly visible to approaching motorists, particularly approaching motorists on the major road are good candidates for this treatment.

Application: This treatment may be considered at any unsignalized intersection, especially intersections with higher speed, curved, or skewed approaches, or locations with other sight distance or visibility limitations.

Considerations: These treatments may be considered when high frequencies of crashes are related to visibility of the intersection, or the intersection footprint is not clearly delineated by striping or pavement markings.

Systemic Application: New or upgraded signs and pavements markings are low-cost treatments that can be implemented systemically and integrated into ongoing maintenance and capital improvement projects.

Crash Reduction Factor: 13 - 60%
Planning-Level Cost: $500 - $5,000 per approach depending on the combination of signing and striping implemented.

262 of 337

February 10, 2023 Page 24
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Improve Sight Distance to Intersection (clear sight triangles) Description: This treatment consists of clearing vegetation, roadside objects, on-street parking, fences, buildings, or other objects in the right-of-way.

Purpose: Clearing obstructions within the vicinity of the intersection improves sight distance at the intersection by providing clear sight triangles on the approach or adjacent to the intersection.

Application: These treatments may be considered at any unsignalized intersection where intersection sight distance is limited by on-street parking or other obstacles.

Considerations: These treatments may be considered when high frequencies of crashes are related to conflicting movements that may be impacted by limited visibility at the intersection. However, sight- distance improvements should be balanced with other concerns (such as the loss of on-street parking) to balance competing needs of the City.

Systemic Application: Some obstructions and on-street parking may be removed from the right-of-way at low cost and implemented systemically. Some obstructions such as earthen berms or buildings may require separate capital improvements to implement.

Crash Reduction Factor: 11 – 56%
Planning-Level Cost: $200 - $50,000 per approach, depending on the extent and type of obstruction.

Install Right Turn/Left Turn Lane
Description: Add an exclusive right turn/left turn lane(s).

Purpose: Sideswipe crashes have been identified as the most frequent crash type reported in the City of San Mateo and improper turning is the primary crash factor for 50% of the sideswipe crashes. 14% of the rear-end crashes and 13% of the broadside crashes have improper turning as a primary crash factor.

Adding a right turn lane is targeted to reduce the frequency of rear-end crashes or conflicts between vehicles turning right and following vehicles; or through vehicles coming from the left on the cross street.

Right-turn lanes also remove slow vehicles that are decelerating to turn right from the through-traffic stream, thus reducing the potential for rear-end collisions.

Adding left-turn lanes removes vehicles waiting to turn left from the through-traffic stream, thus reducing the potential for rear-end collisions. Because they provide a sheltered location for drivers to wait for a gap in opposing traffic, left-turn lanes may encourage drivers to be more selective in choosing a gap to complete the left-turn maneuver.

Application: These treatments may be considered on high-volume and high-speed major-road approaches.

Considerations: When considering new right-turn/left-turn lanes, potential impacts to non-motorized users should be considered and mitigated as appropriate. New lanes can increase the length of the intersection crossing and create an additional potential conflict point for non-motorized users.

263 of 337

February 10, 2023 Page 25
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Systemic Application: If the right-of-way is available, restriping can be a low-cost improvement systemically.

If the treatment involves widening the roadway or acquisition of additional right-of-way, this treatment can be integrated into capital improvement projects.

Crash Reduction Factor: Right turn lane:14-26%; Left turn lane: 9 – 55%

Planning-Level Cost: Varies. Implementing this strategy may take from months to years. At some locations, right-turn/left-turn lanes can be quickly and simply installed by restriping the roadway. At other locations, widening of the roadway, acquisition of additional right-of-way, and extensive environmental processes may be needed.

Create directional median openings to allow (and restrict) left-turns and U-turns
Description: Directional median openings are usually designed to restrict left-turn and U-turn movements at intersections, to help avoid potential traffic conflicts. Figure 17 shows an example of directional median openings at an unsignalized intersection.

Figure 17: Directional Median Openings at Unsignalized Intersection

Source: FDOT
Purpose: Broadside, rear-end, sideswipe, pedestrian-involved and bicyclist-involved crashes are priority areas to reduce crashes in the City of San Mateo. The number of access points, coupled with the speed differential between through and turning vehicles traveling along a roadway, contributes to crashes at higher volumes intersections. Directional median openings that restrict turning movement into and out of an intersection can help reduce conflicts between through and turning traffic.

Application: This treatment may be considered at unsignalized intersections noted as having turning- related crashes on the approaches to the intersection. Directional median openings may be most effective in retrofit situations where high volumes of turning vehicles have impacted safety, and where more extensive countermeasures would be cost prohibitive because of limited right-of-way and constrains of the built environment.

264 of 337

February 10, 2023 Page 26
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Considerations: This treatment may be considered when there is a clustering of similar turning movement- related crashes on an approach to or at the intersection. Impacts to businesses and other land uses closer to the intersection must be considered.

Systemic Application: This treatment may be more suitable as a spot treatment at intersections with high traffic volumes and high turning movement crashes.

Crash Reduction Factor: 51%

Planning Level Cost: $20,000 per opening

Roadway Segment Treatments
Roadway segment related crashes account for 7% of the total and fatal and severe injury crashes in the City of San Mateo. With the crash patterns analysis, increasing driver awareness and speed management have been identified as potential emphasis areas to reduce roadway segment related crashes.

The following two countermeasure categories were identified for the City of San Mateo:
 Install Street lighting
 Speed Management
a. Install Dynamic Speed Feedback Signs
b. Traffic Calming
Street Lighting
Description: This treatment involves adding roadway lighting to improve safety during nighttime conditions.

Purpose: Evenings, dark and no lighting conditions are associated with high pedestrian – involved and bicycle-involved crashes. Crash frequency analysis by time of day has shown that the highest frequencies of crashes occur during 10 PM – 12AM on a typical weekday, 5 – 7 PM and 9 PM – 12 AM on a typical weekend when the conditions are dark.

Providing roadway lighting improves safety during nighttime conditions by:

• Making drivers more aware of their surroundings, which improves perception-reaction times; • Enhancing drivers’ available sight distances to perceive roadway characteristics in advance of the change; or
• Improving non-motorists’ visibility and navigation.

Application: This treatment may be considered at locations with night-time crashes to make drivers aware of the roadway characteristics in the night.

Considerations: This treatment may be considered along segments with notable substantial patterns of nighttime crashes.

Systemic Application: Due to the low cost of installing lighting, this treatment may be implemented systematically or integrated with ongoing maintenance or capital improvement projects.

Crash Reduction Factor: 35%
Planning-Level Cost: $7,000 to $10,000 per light
Speed Management
Unsafe speed was identified as a primary crash factor for 15% of the total crashes and 11% of the fatal and severe injury crashes in the City of San Mateo. Speed management treatments seek to lower vehicular speeds on the roadway, thereby reducing speeding related crashes. Speed management should be addressed comprehensively to encompass all the factors that may influence travel speeds, including road user/driver behavior, roadway design, surrounding land use context, traffic, roadway conditions, posted speed limits, and enforcement.

The following two countermeasures were identified for the City of San Mateo:

1. Install Dynamic Speed Feedback Signs

2. Traffic Calming
Install Dynamic Speed Feedback Signs
Description: This treatment consists of installing dynamic or variable speed feedback signs on the roadway.

Figure 18 shows an example of a dynamic speed feedback sign.

Purpose: Speed feedback signs provide drivers with feedback about their speed in relationship to the posted speed limit. This treatment primarily addresses crashes caused by motorists traveling too fast around sharp curves. It is intended to get the drivers attention and give them a visual warning that they may be traveling over the recommended speed for the approaching curve.

Application: Curvilinear roadways that have an unacceptable level of crashes due to excessive speeds on relatively sharp curves.

Considerations: These treatments may be considered on roadways that have higher incidence of crashes due to excessive speeds, and on relatively sharp curves.

February 10, 2023 Page 28
San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Engineering treatments Kittelson & Associates, Inc.

Systemic Application: This treatment is a relatively low-cost implementation that can easily be implemented systemically or integrated with capital improvement projects.

Crash Reduction Factor: 0 - 41%
Planning-Level Cost: $2,000 - $11,000 per display, depending on whether it is solar powered or AC.

Traffic Calming
Traffic calming is the use of mainly physical roadway design measures to slow motor vehicles as they move through urban, commercial, and residential neighborhoods. These treatments also help to reduce cut- through traffic and improve the safety of non-motorized users by reducing the potential for higher speed and higher severity conflicts. This section describes additional engineering measures that can be used for traffic calming. Many pedestrian and bicycle related treatments also provide traffic calming benefits.

Other speed management treatments such as dynamic speed feedback signs can also be effective for traffic calming.

Description: This group of treatments include Speed Hump, Chicane, Bulb-out, Raised intersections, Mid- block Pedestrian Crossing, and Choker/Pinch Point. The detailed explanation for each of the treatments is below:

• Speed Hump: Rounded (vertically along travel path) raised areas of pavement typically 12 to 14 feet in length and often placed in a series (typically spaced 260 to 500 feet apart) • Chicane: Roadway treatment that creates shifting deviations in the street by the implementation of curb extensions or islands
• Bulb-out: A bulb-out or curb extension visually or physically narrows the roadway to reduce vehicle speeds and create shorter crossings for pedestrians.
• Raised Intersection: Raised area for an entire intersection used to reduced vehicle speeds and create additional awareness of pedestrians at the intersection • Mid-block Pedestrian Crossing: Designated space for pedestrians to cross the street at locations where the nearest signalized intersection is too far to walk to and includes striping and physical features that reduce vehicle speeds.
• Choker/Pinch Point: Mid-block narrowing of roadway that requires drivers to slow down or yield to each other to maneuver through the area.

Purpose: Traffic calming is the combination of measures that lower vehicle speeds, alter driver behavior, and improve conditions for non-motorized street users.

Considerations: Traffic calming has many potential applications, especially in residential neighborhoods and small commercial centers. Some treatments may impact existing roadway drainage and on-street parking.

Systemic Application: These treatments are relatively low-cost implementations that can easily be implemented systemically or integrated with capital improvement projects.

Crash Reduction Factor: Varies by treatments
Planning-Level Cost: $5,000 - $25,000 per location

City of San Mateo Neighborhood Traffic Calming Policy: In October 2006, San Mateo City Council adopted a Neighborhood Traffic Calming Policy as part of its overall neighborhood traffic mitigation efforts. The goal of this policy is to enhance traffic and pedestrian safety and preserve neighborhood character and livability. Traffic calming measures adopted by the City are primarily engineering measures divided into two categories:

• Step 1: This category includes easy to implement, low-cost tools such as radar speed display signs, most sign installations (excluding stop signs and turn-prohibition signs), high visibility crosswalks, narrow lane striping, neighborhood traffic safety campaigns, neighborhood speed watch programs and targeted police enforcement.
• Step 2: This category includes measures that alter street configuration, impede traffic flow, and change travel patterns such as stop signs, curb extensions, speed cushions, traffic circles and roundabouts, median barriers, etc. In general, these measures are more expensive than Step 1 measures.

In 2015, the City of San Mateo developed an outreach program to gather inputs from various neighborhoods within the City regarding their traffic safety concerns. The City utilized each neighborhood’s concerns and feedback on traffic calming measures and drafted 13 Traffic Action Plans specific to each neighborhood.

EDUCATION STRATEGIES
Education strategies are focused on teaching road users, road safety principles. These strategies can be developed to include interactive activities, comprehensive teaching notes, and information on road safety messages and concepts that can be taught at school or in off-school activities. The following six education- related strategies were identified for the City of San Mateo.

 Road Safety Education to Children
 Speed Monitoring Awareness Radar Trailer
 Conspicuity Enhancements and Education
 Vulnerable Road User Education
 High-Visibility Cell Phone and Text Messaging Media Campaign  DUI Educational Programs
Road Safety Education to Children
Road safety education to children includes strategies such as safe routes to school, walking school bus, and bicycle trains that promote road safety to all users, particularly for pedestrians and bicyclists. A ‘safe routes to school’ program would encourage and enable children to walk and bike to school. This can improve their health, well-being, and safety. This also results in less traffic congestion and emissions caused by school-related travel. Walking school buses and bicycle trains encourage groups of children walking or biking to school, with one or more adults.

As part of the Safe Routes to School program10, the City of San Mateo has conducted pedestrian and bicycling safety workshops to create safety awareness and encourage students to get to school by means other than a car. The San Mateo County Safe Routes to School Five-Year Education program11 has implemented walk and bike to school day, bike and helmet giveaways, walking school buses, bike rodeos,

pedestrian safety month and walking and biking audits12. . A parent survey in 2014-2015 school year identified the following issues for walking/biking to and from school in San Mateo County:
• Speeding traffic along route
• Unsafe intersections
• Too much traffic along route
• Stranger danger
• Distance to school
• Lack of adults to walk with
Speed Monitoring Awareness Radar Trailer
The speed trailer is an educational device that helps drivers become more aware of their speed in relation to the posted speed. This awareness tool can also help residents survey the traffic speeds in their own neighborhood. This trailer is usually deployed in a street or neighborhood for a few days so the residents can monitor the speeds on their own streets and become aware of their own driving behaviors.

Conspicuity Enhancements and Education
The purpose of enhancing conspicuity for pedestrians is to increase the opportunity for drivers to see and avoid pedestrians, particularly when it is dark. In the City of San Mateo, 32% of fatal and severe injury pedestrian -involved crashes occurred in the evening when it is dark and it is 4.0 times more likely for a pedestrian-involved crash that occurs when it is dark with no lighting to result in a fatal or sever injury..

Educating pedestrians to wear reflective clothing and walk in well-lit areas can be implemented as targeted campaigns. The use of high visibility clothing and protective gear enhances safety. There is some limited evidence to suggest that a program aimed at increasing conspicuous and protective clothing could be successful.

Vulnerable Road User Education
The road safety education regarding vulnerable road users like pedestrians and bicyclists includes strategies involving education from police officers. If the driver encroaches into the bike lane or fails to yield to the pedestrian at the crossing, the police officer pulls the driver over and hands them a flyer that has the information for drivers to adapt their behavior towards all road users; this can be in addition to a citation.

High-Visibility Cell Phone and Text Messaging Media Campaign The High Visibility Enforcement model combines dedicated law enforcement with paid and earned media supporting the enforcement activity. Paid media includes advertisements on TV, radio, online, and via billboards, while earned media includes things like press events and news releases covering the efforts. Both types of media support enforcement activities are needed to ensure the public is aware of the enforcement activity, and to create the impression that violators will be caught.

DUI Educational Programs
An educational program to reduce driving under the influence of drugs or alcohol may help improve safety throughout the County. A DUI program may involve working with stakeholder partners to identify

San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Enforcement Strategies Kittelson & Associates, Inc.
opportunities to influence driving under the influence behaviors, as well as coordinating with enforcement to identify focus locations for enforcement activities and education opportunities. It may also be beneficial to implement educational programs with local school districts to target underage impaired driving.

ENFORCEMENT STRATEGIES
Even when engineering countermeasures are implemented, road users failing to adhere to traffic laws can result in crashes of varying severity. Police enforcement can increase driver awareness and consequently reduce traffic crashes. Potential enforcement strategies to address crash patterns and trends in City of San Mateo are presented below. However, enforcement strategies should be undertaken with due caution to avoid inequitable enforcement activities and evaluated to determine the strategy’s impact.

The following considerations can help lead to more successful outcomes for roadway safety enforcement strategies:
 Police officers should be trained properly beforehand.  Campaigns should be tailored to suit the needs of different neighborhoods and demographics and should be designed and carried out to avoid targeting disadvantaged communities.  Enforcement should be conducted with the help of staff support and awareness of the courts.  Enforcement operations should begin with warnings and flyers before moving on to issuing citations.

City staff can also help monitor the impact of the enforcement strategy by coordinating with the City of San Mateo Police Department to obtain and analyze enforcement records to help evaluate effectiveness and equity considerations.

The following enforcement strategies have been identified for the City of San Mateo:
 Progressive Ticketing
 Speed Enforcement in School Zones
 High Visibility Saturation Patrols
Progressive Ticketing
Progressive ticketing is a method for introducing ticketing through a three-staged process. Issuing tickets is the strongest strategy of an enforcement program and it is usually reserved for changing unsafe behaviors that other strategies failed to change or that pose a real threat to the safety of road users. There are three main steps of an effective progressive ticketing program:

• Educating - Establish community awareness of the problem. The public needs to understand that drivers are speeding and the consequences of this speeding for road safety. Raising awareness about the problem will change some behaviors and create public support for the enforcement efforts to follow.
• Warning - Announce what action will be taken and why. Give the public time to change behaviors before ticketing starts. Fliers, signs, newspaper stories and official warnings from officers can all serve as reminders.
• Ticketing – After the “warning” period, hold a press conference announcing when and where the police operations will occur. If offenders continue their unsafe behaviors, officers issue tickets.

San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Equity Strategies Kittelson & Associates, Inc.

Speed Enforcement in School Zones
Strict enforcement of speed laws in school zones is one law enforcement tool that can improve the safety for children walking and bicycling to school as well as drivers. A ‘zero tolerance’ policy for speeders in school zones and even an increase in fines for drivers who violate the posted school zone speed limit are potential approaches.

High Visibility Saturation Patrols
A saturation patrol (also called a blanket patrol or dedicated DWI patrol) consists of many law enforcement officers patrolling a specific area to look for drivers who may be impaired. These patrols usually take place at times and locations where impaired driving crashes commonly occur. Like publicized sobriety checkpoint programs, the primary purpose of publicized saturation patrol programs is to deter driving after drinking by increasing the perceived risk of arrest.

The City of San Mateo’s Neighborhood Traffic Management Program13 identifies “Enforcement” as one of the key strategies to address speeding problems. The Traffic Action Plan for Sunnybrae Neighborhood in the City of San Mateo14 has identified speeding as one of the key areas of concern for traffic safety and recommended targeted police enforcement based on time of day and vehicle speeds on select roadways in the neighborhood. City Staff worked with other City’s neighborhoods to develop similar enforcement strategies that would address speeding issues specific to each community and incorporated these strategies into respective neighborhood’s Traffic Action Plans.

San Mateo Police Department held a traffic enforcement day throughout the city in April 202115, during which the police cited 45 drivers and warned pedestrians at-fault. Traffic enforcement operation was taken up after the Police Department held several traffic education programs, with the police giving out more than 100 warnings over three days. Traffic enforcement was also based on data-driven times, peak hours and peak crash times. With the observations from traffic enforcement day, the City plans to enhance pedestrian safety enforcement operations and increase safety awareness for drivers.

EQUITY STRATEGIES
Equity is defined as the fairness with which benefits, and burdens are distributed and how disparities, including those based on age, race/ethnicity, income and gender, are identified and addressed within specific populations (National Safety Council16).

Notable statistics from crash patterns analysis for the City of San Mateo regarding population demographics of involved party members include:
• Only 16% of the City’s population are 65 years old and over. But they are over-represented in number of pedestrian-involved crashes (25%) and bicycle-involved crashes (29%) fatal and severe injury crashes,
• Considering that 7% of the City’s population were considered between the ages of 18 and 24 years, there were a significantly high number of drivers (17%) and bicyclists (21%) between 18 and 24 years of age involved in a fatal or severe injury crash,

• Pedestrians under 18 were also involved in a relatively high number of fatal and severe injury crashes (25%),
• Hispanic and Black populations were overrepresented by at least 20% and 50%, respectively, in crashes across all party types.

Incorporating equity as part of engineering, education and enforcement strategies discussed above can help address these and other existing disparities in the City.

The following equity strategies have been identified for the City of San Mateo:
• Engineering: An equitable approach to engineering countermeasures must consider and should include, but is not limited to:
o Investing in infrastructure in an equitable manner to reduce traffic accidents, prioritizing historically disinvested neighborhoods, or neighborhoods overrepresented for crashes; o Creating contextually sensitive plans and solutions and avoiding one-size-fits-all-solutions.

For instance, infrastructure plans can be designed keeping in mind different kinds of roadway users including children, senior citizens, people with disabilities; o Involving a diversity of people in testing and design to increase safety. • Education: An equitable approach to education strategies must consider and should include, but is not limited to:
o Developing, executing, and implementing programming with community voices included in the process, particularly those representing disadvantaged and/or highly impacted communities;
o Using images, language, and media that is reflective of the community and audience; o Working with trusted ambassadors, spokespeople, and community leaders to help in the execution of any campaigns or programs.
• Enforcement: An equitable approach to enforcement strategies must consider and should include, but is not limited to,
o Adopting income-based repayment for traffic tickets;
o Understanding whether and how enforcement of traffic safety laws or regulations can exacerbate existing racial, socioeconomic, or accessibility issues, and subsequently working with stakeholders to identify solutions;
o Educating and training those working on enforcement on equitable enforcement practices and techniques;
o Assessing whether new or alternative forms of enforcement can be deployed to effectively address the issue at hand, including automated enforcement and community policing.

As part of its data transparency efforts, the City of San Mateo collects and reports policing data and data on traffic collisions17. To further the data collection and transparency efforts and to improve its equity in transportation, the City may consider reporting all traffic stops and searches. Stop records should include the location of the stop, demographic information about the stopped person, the reason of the stop, the outcome of the stop, whether any searches were conducted and the outcome of any searches, The information provided in the sections above is adapted from Center for Policing Equity: Traffic Safety Recommendations18 and National Safety Council: Equity in Transportation Best Practices Framework19.

San Mateo Local Roadway Safety Plan - Safety Countermeasures Toolbox Memorandum Emerging Technologies Strategies
Kittelson & Associates, Inc.

EMERGING TECHNOLOGIES STRATEGIES
This section notes innovative approaches to improve roadway safety by accelerating road safety understanding using technology, thereby helping transition to safer transportation systems. Focus areas include but are not limited to:

 Artificial Intelligence and Deep Learning
 Big Data
 Fleet Related Technology
 Touchless Tire Pressure Monitoring
The Road Safety Innovation List (2021) identified the following new technologies and approaches for safety management.

Artificial Intelligence and Deep Learning
This technology applies artificial intelligence and deep learning on traffic video feed (such as existing CCTV traffic cameras) to perform automated video analysis of traffic flow for effective and immediate road safety diagnosis and evaluation of conflicts. The combination of artificial intelligence and vehicle-to- everything (V2X) technology is designed to predict vehicles and pedestrians’ intent and prevent conflicts that may result in crashes. This technology is now being tested in autonomous vehicles and applications are being developed for use by jurisdictions to apply at intersections or networks. (https://trid.trb.org/view/772920).

Big Data
New “Big Data” information measures all kinds of activity in streets including volumes, paths, speeds, and behaviors of pedestrians, bicycles, different types of vehicles, wheelchairs, and scooters on the roadway.

These data platforms provide data on curb-level activity and help engineers and planners design safer and more efficient streets by helping to detect conflicts and address potential road user behaviors and patterns before crashes occur.

Mobile phone data and machine learning algorithms are being designed to identify high-risk driver behavior before a crash occurs. Using the smart phone sensors, the behavioral data provides actionable insights that improve safety for all road users.

Fleet Related Technology
Vehicle fleet technology integrates the driver-assisting platooning system to all commercial fleets, and links the active safety systems between freight trucks, detects oncoming vehicles, pedestrians, and bicyclists and alerts drivers in advance to avoid them with real-time warnings.

Touchless Tire Pressure Monitoring
Touchless tire pressure monitoring is a new technology which measures tire pressure in real time. This has been implemented in two locations near the turnpike in Central Florida. Drivers must simply drive over the “Wheel Right” station to learn what their current tire pressure is and if the tires are ready for the road or low

on pressure. This is a safety feature that can help prevent blowouts and accidents on the road by warning drivers ahead of time when they need to maintain their vehicle.

NEXT STEPS
This memorandum summarizes the prioritized engineering and non-engineering countermeasures that could be implemented across the City of San Mateo as well as considerations for their application.

Combined with the results of the Crash Data Analysis Memorandum, these countermeasures will form the basis for identifying treatments at priority intersections and roadways across the City. Following review by City staff, Kittelson will finalize the countermeasure memo and develop safety projects for the priority locations as identified in collaboration with City staff.

SUBJECT:

Local Roadway Safety Plan Introduction
RECOMMENDATION:

Receive information about the Local Roadway Safety Plan BACKGROUND:

The California Transportation Commission allocated $18 million of State funds in 2019 and 2020 for the purpose of assisting local agencies in developing Local Roadway Safety Plans (LRSPs) based on new statewide requirements for cities to have an LRSP or equivalent plan to be eligible to apply for federal Highway Safety Improvement Program (HSIP) funds.

LRSPs utilize crash data to help identify safety goals for reducing fatal and severe injury crashes, identify roadway safety emphasis areas, and prioritize safety improvements with the help of community feedback and stakeholders representing engineering, law enforcement, education, and emergency response personnel.

Staff applied for $72,000 in grant funds to develop a LRSP in March 2020 and was awarded the grant in early 2021. Due to staffing constraints and shifted priorities due to the COVID-19 pandemic, the project was initiated in August 2022. To date, the project team has completed initial parts of the project including review of relevant safety-related policies from the local level through the federal level, identification of crash trends in the city based on collision data, created a draft toolkit of measures to address crash trends, and developed a community outreach plan. In the meeting, the project team will present some of the early findings from the analysis completed to-date and discuss the project’s next steps, including an overview of community outreach and a timeline for the draft plan.

BUDGET IMPACT:

There are no budget impacts for receiving information about the Local Roadway Safety Plan.

ENVIRONMENTAL DETERMINATION:

This informational update is not a project subject to CEQA, because it is an organizational or administrative activity that will not result in direct or indirect physical changes in the environment. (CEQA Guidelines Section 15378(b)(5).)

SUBJECT:

Draft Local Roadway Safety Plan - Update
RECOMMENDATION:

Receive an update on the draft Local Roadway Safety Plan and provide feedback.

BACKGROUND:

The City’s Local Roadway Safety Plan (LRSP) creates a data-driven and community-informed decision-making framework that will work toward the goal of eliminating fatal and severe injury collisions on local roadways. The LRSP uses historical collision data and an understanding of local context to assess existing roadway safety conditions in San Mateo, identifies areas for improvement, and provides recommended actions and an implementation plan that will help create a Safe System (an approach to roadway safety adopted by the United States Department of Transportation and Caltrans) and culture of roadway safety in the City of San Mateo. Additionally, having an approved LRSP qualifies the City for certain types of grant funding, such as the Highway Safety Improvement Program (HSIP) and Safe Streets for All (SS4A) grant programs.

In July 2023, staff gave an informational presentation to the Sustainability and Infrastructure Commission on initial LRSP development efforts, including outlining collision analysis findings, the community outreach plan, and project timeline.

Since that meeting, community outreach has been completed and the draft LRSP has been completed. The LRSP is organized into five sections:

1.Vision, Mission, and Goals – Establishes a larger vision for transportation safety in San Mateo and sets goals for how to get there.

2.Plan Development Process – Details the collaborative data-driven and community-informed planning process.

3.Existing Safety Conditions – Provides an analysis of collisions in San Mateo.

4.Emphasis Areas, Countermeasures, and Strategies – Details the emphasis areas and lists proven countermeasures and strategies that can improve roadway safety.

5.Recommendations, Actions, and Implementation – Prioritizes short- and long-term projects and sets a strategy for assessing progress toward established goals.

The project team will present the draft LRSP, including information about site-specific improvements recommended at priority locations. The presentation will also include systemic safety improvements, which are improvements that can be made proactively at locations that don’t have collision data trends but have similar characteristics to locations that do.

Staff will be seeking both broad feedback about the entirety of the Draft LRSP, as well as specific feedback about proposed systemic treatments to confirm that they are appropriate measures for the identified data trends and community feedback received. Following the meeting the project team will incorporate Commission feedback, then will bring the Local Roadway

Safety Plan to City Council in the next few months.

BUDGET IMPACT:

There are no budget impacts for receiving an informational presentation about the Local Roadway Safety Plan. The project is funded through Caltrans grant funds, matching funds from the Citywide Traffic Calming project (466600) and supplementing funds from the Neighborhood Traffic Management project (462226).

Hello council, two thoughts on the LRSP to be discussed this evening. Please don't hesitate to reach out on either topic. I would love to discuss further with all of you!

1. No Right Turn On Red (No RTOR) specifically for our Downtown Core We currently have Lead Pedestrian Intervals (LPI) in our Downtown Core. The LPIs allow for visibility and safety of pedestrians while walking downtown which is unique compared to other areas I've visited on the peninsula. As the LRSP mentions No RTOR is another low cost and high impact option in addition to our current LPIs for making our Downtown Core even safer for all users (drivers, pedestrians, etc...). San Francisco has studied this change extensively and found that in areas where they were implemented No RTOR 92% of motorists compiled with No RTOR, “close calls” between cars and people walking decreased by 80%, and cars blocking or encroaching crosswalks during a red light decreased more than 70% [1]. Similar results in Washington DC showed a 97% decrease in conflicts between cars as well [2]. This policy helps create safer streets for all users including drivers and would be a common sense and low cost option for making our Downtown Core even more amazing! Multiple cities in the United States have approved and/or implemented No Turn On Red policies — some of which are citywide policies, some are specific areas — including New York City, Cambridge, Massachusetts, Washington, District of Columbia, and Ann Arbor Michigan.

2. Safe Systems Pyramid
As you are considering different options for making our streets safer and more accessible please keep the Safe Systems Pyramid in mind. Safe Systems approaches are mentioned in the document for discussion tonight but not this detail which I find helps pull apart the impact and expectations we should have for different approaches.

Two examples (stolen from [3] if you want more detail):

An individual-level strategy is encouraging people to drive a safe speed via education campaigns (billboards, radio ads) and the threat of getting speeding tickets. These have some, but not widespread, deep and lasting impacts.

A population-level strategy would be road designers physically separating people driving from people walking and biking wherever possible with fully separated,
