This project will construct 9,000 square feet of bioretention area at an existing 24-inch storm drainpipe in order to treat runoff from five acres of existing impervious public roadway and sidewalks. The existing storm drain will be redirected to the bioretention area for treatment prior to flowing to the existing creek outfall. The existing irrigated grass turf within the bioretention footprint will be replaced with drought-tolerant native plantings. Similarly, irrigated grass turf adjacent to the regional trail and in areas of low activity within the park will be replaced with low-water use native plantings to more closely match the naturalized creek planting along the Regional Trail. Interpretive signage explaining the benefits provided by green infrastructure and associated landscaping. Extension of public sidewalk along Solano Wy to improve pedestrian mobility, the existing pathway connecting the two routes is pedestrian focused and improving the connections at each end of the connecting path will ease the maneuvering and encourage use of the park by cyclists. The park is located close to multiple trail connections, so wayfinding and informational signs are proposed, as well as a water station for cyclists.

Subject: Capital Budget Related Questions from the Mayor--Item 6.b This e-mail is being shared with all Councilmembers

Mayor Nakamura,

Yesterday you asked the following capital project related questions. Each is below with a response from staff.

Will funding sources be shared during the PowerPoint presentation for items proposed for funding:

Staff Response: Yes

Is Turtle Creek planned for a repaving?

Staff Response: Turtle Creek is not in the proposed two-year Capital Budget nor in the five-year Capital Infrastructure Plan. Turtle Creek will be evaluated again, as will all roadways, as the five-year roadway investment plan gets updated later this year and its status could change through that process. Please remember that there are more roadways in need of investment than dollars available. Consequently, the City employs critical point investment strategy, and which roadways are selected for investment depends upon a roadway’s scoring through this process. This will be discussed/presented as part of tonight’s presentation on the Capital Budget.

As a reminder: The five-year Capital Investment Plan (CIP) is the two-year capital budget (the focus of tonight’s presentation) and projects proposed to occur in the three following years. The projects in year 3 thru 5 of the CIP are generally not funded (although some show how they could be funded if it is from a known, reliable funding source—like SB 1 or gas tax). Having certain projects in the five-year plan allows staff to pursue grants and Agenda Item No. 6.b

assists with future planning but they are not active Capital Projects until funded and placed into a two-year Capital Budget.

Is Pine Hollow planned for a repaving?

Staff Response: Pine Hollow is not in the proposed two-year Capital Budget but is in the five-year Capital Infrastructure Plan as a complete streets project—that will rely on obtaining a grant to occur.

You asked for clarity during tonight’s presentation on what projects are pending, in progress, and/or planned.

Staff Response: During the presentation tonight, staff will present projects in groups, as follows: completed projects, upcoming projects that are already fully funded, new and continuing projects that need more funding. These last two categories make up the two-year Capital Budget that Council will be asked to adopt in June. Planned/partially funded projects outside of the 2-yr Capital Budget, but in the CIP in the out three years will not be presented tonight. These projects are listed in Attachment 4 to the staff report.

To: City Council
From: Valerie J. Barone, City Manager
Reviewed by: Kit Jory, Director of Public Works
Prepared by: Abhishek Parikh, Deputy Director PW - Transportation [email protected]

Subject: Considering Adoption of the City of Concord Comprehensive Safety Action Plan (CSAP) developed under the Safe Streets and Roads for All (SS4A) Federal Grant Program.

CEQA: Not a project/exempt per CEQA Guidelines Sections 15060(c), 15061 (b)(3), 15378, and/or Public Resources Code Section 21065.

Report in Brief
The CSAP is grounded in a five-year collision analysis (2021–2025) of 1,804 total injury collisions, of which 164 (9%) involved fatal (19) or severe injuries (145). The Plan (Attachment 2) identifies the corridors where severe collisions are most concentrated, the High Injury Network; lists the fourteen existing Concord plans that align with CSAP’s goals; outlines a Safe Streets Toolkit of evidence-based countermeasures drawn from Federal Highway Administration (FHWA) research; and establishes a project prioritization framework for implementation. Adoption of the CSAP will enable the City to compete for SS4A implementation grants and other Federal and State safety funding for which an adopted comprehensive safety action plan is a prerequisite.

Recommended Action
Adopt a Resolution adopting the City of Concord Comprehensive Safety Action Plan (CSAP) as developed under the Safe Streets and Roads for All (SS4A) Grant Program; authorize the City Manager to submit the adopted Plan to the U.S. Department of

City Council Agenda Report
Agenda Item No. 6.c
May 12, 2026
Transportation in accordance with the Safe Streets for All (SS4A) Grant Program requirements; and make the CEQA determinations as provided in this staff report.

Background
In June 2025, City Council approved a Professional Services Agreement with TJKM Transportation Consultants, who led the development of the CSAP. City staff directed the scope, managed the engagement process, provided local data and policy context, conducted community outreach, and shaped the Plan’s recommendations in alignment with City Council’s priorities and the City’s Vision Zero goals. The CSAP was developed using the Safe System Approach — a framework that acknowledges human error is inevitable and designs the road system to minimize the serious consequences of crashes.

The CSAP project objectives include:

1. Data-Driven Analysis: Conduct a comprehensive five-year assessment of traffic collision data to identify high-risk intersections and corridors, high-injury networks, and prevalent contributing factors across all modes.

2. Community Engagement: Engage diverse community stakeholders to gather insights, reflect the safety needs and priorities of all residents, and ensure the Plan’s strategies are informed by those most affected by traffic safety challenges, including residents in historically underserved communities. The CSAP engagement program included a dedicated project website (concordsafestreets.org), a multi-agency Steering Committee convening representatives from four agencies (BART, County Connection, Contra Costa Fire District and Mount Diablo School District) across three steering committee meetings, three public community outreach meetings, a citywide online safety survey generating 651 responses, a web-based map input platform collecting 77 location-specific comments, and a presentation to the Bicycle and Pedestrian Advisory Committee on May 6, 2026.

3. Existing Plans Review: Review and align the CSAP with fourteen existing City and regional plans, policies, and programs, to ensure the Plan improves upon existing efforts and does not duplicate prior safety investments.

4. Safe System Countermeasures: Develop a Safe Streets Toolkit of evidence-based engineering, enforcement, and education countermeasures drawn from FHWA research and calibrated to Concord’s specific collision patterns and High Injury Network findings.

5. Implementation Framework: Provide a clear roadmap for prioritizing and executing recommended safety measures, including project identification, performance metrics, and potential funding sources.

City Council Agenda Report
Agenda Item No. 6.c
May 12, 2026
Enhanced Collision Dashboard: Upgrade Concord’s existing Collision Dashboard to incorporate CSAP implementation tracking, map countermeasures to collisions, automate project identification for grant applications, provide enforcement analytics for red-light running, and develop a query interface to identify trends and correlations among collision factors.

Analysis
CSAP is organized into the following chapters, each addressing a core component of the City’s comprehensive safety strategy:

Chapter 1 – Introduction establishes the CSAP’s purpose, policy context, and organizing framework. It documents the City’s formal commitment to Vision Zero, presents the Safe System Approach and its five pillars (Safe Road Users, Safe Vehicles, Safe Speeds, Safe Roads, and Post-Crash Care), and situates the Plan within its Federal SS4A program context.

Chapter 2 – Existing Plans, Policies, and Programs inventories and synthesizes fourteen existing plans and programs relevant to transportation safety in Concord.

These include the Concord 2030 General Plan Transportation Element (2015), the Bicycle, Pedestrian & Safe Routes to Transit Plan (2016), the Complete Streets Feasibility Study for Willow Pass Road, Galindo Street and Cowell Road (2020), the Local Roadway Safety Plan (2022), the Pine Hollow Road Complete Streets Feasibility Study (2023), the Contra Costa County Complete Streets Safety Assessment (2024), the Five-Year Capital Improvement Plan FY2025–2029 (2024), and the Safe Trips to BART: An Action Plan for Safer Roadways (2025), among others. Each document is assessed for how it informs the CSAP’s goals, ensuring the Plan builds upon and aligns with prior safety investments without duplication.

Chapter 3 – Data-Driven Safety Analysis presents the technical foundation of the CSAP. Five years of collision records (2021–2025) drawn from the Transportation Injury Mapping System (TIMS), the Statewide Integrated Traffic Records System (SWITRS), and Concord Police Department reports were analyzed across multiple dimensions including severity, mode, time of day, day of week, location type, collision type, and contributing factors. Key findings include:
• 1,804 total collisions were reported over the five-year study period. Of these, 164 (9 percent) involved fatal or severe injuries (KSI), comprising 19 fatal collisions (20 fatalities) and 145 severe injury collisions. An additional 427 collisions resulted in visible injuries, while the remaining 1,213 were classified as complaints of pain.
• Vulnerable road users are significantly overrepresented in severe outcomes relative to their share of total collisions: pedestrian-involved collisions account for 28 percent of KSI while representing only 11 percent of all injury collisions;

City Council Agenda Report
Agenda Item No. 6.c
May 12, 2026
bicyclists account for 13 percent of KSI and 8 percent of injury collisions; motorcyclists account for 19 percent of KSI and 7 percent of injury collisions • Broadside collisions are the most prevalent collision type, accounting for 38 percent of all injury collisions and 29 percent of KSI collisions, consistent with the high concentration of collision activity at intersections and identifying intersection safety as the central focus for safety investment. • The analysis culminates in the identification of Concord’s High Injury Network (HIN) the corridors and intersections where fatal and serious injury collisions are most heavily concentrated — which provides the spatial framework for prioritizing safety investments. Collision profiles were also developed to characterize recurring crash patterns by severity, mode, and contributing factor, directly informing the countermeasure selection Chapter 4 – Community Engagement and Outreach documents a robust community engagement program conducted from February through May 2026 to support development of the CSAP. Recognizing that traffic safety is a shared responsibility, the process prioritized input from residents, partner agencies, and local stakeholders to identify concerns, validate technical analyses, and build support for recommended strategies. Engagement efforts included a dedicated project website (www.concordsafestreets.org), a multi-agency Steering Committee, three public outreach meetings, a citywide online safety survey, an interactive web-based map input tool, and a presentation to the Bicycle and Pedestrian Advisory Committee. The project website served as a central information hub, while the Steering Committee—comprising representatives from key local and regional agencies—provided technical oversight and policy guidance through a series of meetings. Three community outreach meetings, held between March and May 2026, created multiple opportunities for the public to review findings, provide feedback, and shape the Plan’s recommendations.

Community input was extensive and directly informed CSAP’s priorities. The online survey generated 651 responses, revealing high levels of concern about traffic safety, with speeding and red-light running identified as top issues and strong support for enforcement and pedestrian-focused improvements. The interactive map tool produced 77 submissions highlighting 106 safety concerns, with the greatest concentration along major corridors such as Willow Pass Road, Concord Boulevard, Treat Boulevard, and Monument Boulevard—locations that align closely with the High Injury Network identified through collision data analysis. Overall, the strong alignment between community-identified concerns and technical findings underscores the validity of the CSAP’s recommendations and reflects a plan that is both data-driven and community- informed.

Chapter 5 – Safe Streets Toolkit presents a comprehensive suite of evidence-based countermeasures drawn from FHWA research, including the Crash Modification Factor (CMF) Clearinghouse, to guide implementation of the CSAP. Countermeasures are

organized into four categories: Signalized Intersections, Unsignalized Intersections, Roadway Segments, and Additional Countermeasures (education, enforcement, and programmatic initiatives). Each countermeasure is characterized by the collision types it addresses, its Crash Reduction Factor (CRF), expected service life, and systemic implementation potential. The Toolkit is designed as a flexible technical resource for City staff to select context-sensitive improvements based on site-specific conditions, collision history, and available resources — not a prescriptive list. Consistent with the Safe System Approach, the Toolkit integrates engineering, enforcement, and education strategies, recognizing that infrastructure improvements must be complemented by behavioral programs to address speeding, impaired driving, distracted driving, and failure to yield.

Chapter 6 - Proposed Safety Projects identifies 16 proposed projects across four categories, informed by 1,804 injury collisions recorded citywide from 2021–2025. All projects are subject to further engineering analysis and environmental review, and implementation is contingent upon the availability of funding for design and construction.

These projects are also presented in Attachment 3.

High Injury Network Corridor Improvements (Projects 1, 4, 5, 6, 7, 8, 9, and 10) • Project 1 would implement targeted multimodal safety improvements along five HIN-priority corridors — Clayton Road, Monument Boulevard, Willow Pass Road, Concord Avenue, and Galindo Street — collectively associated with 687 injury collisions, including 8 fatalities and 52 severe injuries.

Improvements include speed feedback signs, enhanced lighting, LPI, high- visibility crosswalks, ADA curb ramps, HFST, C-V2X technology, EVP GPS, and access management medians. This project is to be proposed under an SS4A Implementation Grant anticipated to be submitted on June 26. • Project 4 would close bicycle facility gaps on Monument Boulevard, Cowell Road, Galindo Street, Diamond Boulevard, Market Street, and Clayton Road through shared-use path enhancements, protected bike lane intersection treatments, and crossing improvements.
• Project 5 would address Concord Boulevard (SR-242 to Kirker Pass Road) with sidewalk gap closures, HAWK/beacon crosswalk upgrades, and speed feedback signs near two schools.
• Project 6 would implement median, signal, and pedestrian crossing improvements on Port Chicago Highway, including at Bonifacio Street and North 6th Street, where broadside and pedestrian collision patterns exist. • Project 7 would improve delineation, edge lines, rumble strips, and lighting on the northern segment of Willow Pass Road.

City Council Agenda Report
Agenda Item No. 6.c
May 12, 2026
• Project 8 would address Treat Boulevard (Winton Drive to Clayton Road) with signal upgrades, Lead Pedestrian Interval (LPI), Pedestrian Hybrid Beacon (HAWK signals), High Friction Surface Treatment (HFST) and a feasibility study for a bicycle and pedestrian connection between San Miguel Road and Marietta Circle.
• Project 9 would install a raised median, speed feedback signs, and crosswalk enhancements on Oak Grove Road, including at the Contra Costa Trail crossing.
• Project 10 would address geometric, signing, striping, HFST, guardrail, and median improvements on Ygnacio Valley Road and Kirker Pass Road.

Complete Streets and Active Transportation (Projects 2 and 3) • Project 2 would advance design and construction of complete street improvements on Monument Boulevard (Iron Horse Trail to Walters Way), Cowell Road, and Galindo Street, building on an existing feasibility study implementation of the projects listed in this section is anticipated through a combination of competitive Federal, State and Regional funding program. • Project 3 would implement a Safe Routes to School program citywide, including curb reconfiguration, raised crosswalks, advanced stop bars, dynamic signage, and bike lanes near schools.

Citywide Safety Programs (Projects 11 and 12)
• Project 11 would fill sidewalk gaps citywide, prioritizing HIN corridors with pedestrian collision history — including Clayton Road, 6th Street, and Cowell Road.
• Project 12 would install LPI and right-turn-on-red restrictions at approximately 15 intersections with recorded pedestrian severe-injury collisions.

Planning and Policy Initiatives (Projects 13, 14, 15, and 16) • Project 13 would fund complete street feasibility studies and preliminary design on seven HIN corridors — Clayton Road, Willow Pass Road, Treat Boulevard, Concord Avenue, Market Street, Detroit Avenue, and Diamond Boulevard (approximately 12+ miles combined) to establish the engineering foundation for future capital investment.
• Project 14 would establish a corridor speed management program with data collection, hotspot identification, and speed feedback deployment, responding to unsafe speed as a contributing factor in collisions.

City Council Agenda Report
Agenda Item No. 6.c
May 12, 2026
• Project 15 would create a formal citywide traffic calming policy and program for residential neighborhoods, defining program criteria, eligible treatments, and a prioritization process.
• Project 16 would deploy machine-learning traffic conflict sensors and smart infrastructure on key corridors and school zones to identify near-miss patterns and guide future investment, consistent with the City's Transportation Management Center vision and SMART grant eligibility.

Chapter 7 – Implementation, Evaluation, and Funding Strategy establishes the framework for implementing, monitoring, and evaluating the CSAP to ensure continued progress toward the City’s safety goals. Consistent with SS4A program requirements, the CSAP is intended to function as a living document, with periodic updates to incorporate new collision data, assess the performance of implemented projects, and reflect evolving best practices. Implementation of CSAP recommendations will be coordinated with the City’s Capital Improvement Program (CIP) and prioritized using a data-driven methodology that emphasizes collision frequency and severity, project readiness, and cost-effectiveness, with a focus on locations within the City’s High Injury Network. The chapter establishes a performance monitoring framework that includes tracking key measures such as reductions in fatal and serious injury collisions and implementation progress for prioritized projects. Concords enhanced collision dashboard will support ongoing monitoring and public reporting.

Relationship to Grant Funding
Adoption of this CSAP satisfies SS4A Action Plan requirements and positions the City to compete for SS4A Implementation Grant funding, with awards ranging from $2.5 million to $25 million on an 80/20 Federal-to-local cost split, and a Federal application deadline of May 26, 2026. In addition to SS4A, the Chapter identifies a diversified funding strategy spanning the Highway Safety Improvement Program (HSIP), Active Transportation Program (ATP), Office of Traffic Safety (OTS) grants, One Bay Area Grant (OBAG) program, CCTA Measure J and Measure X, and other Federal and State sources aligned with CSAP project types.

Financial Impact
There is no additional financial impact associated with adopting the CSAP. The total project budget of $445,928.89 was previously approved by City Council in June 2025 and is funded by $400,000 in USDOT SS4A grant funds and $100,000 in local matching funds set aside in CIP Project No. 2782. Adoption of the CSAP will position the City to apply for SS4A implementation grants and other Federal and State safety funding opportunities for which an adopted comprehensive safety action plan is a prerequisite.

________________, 2026
Dear Members of the Community,
I am writing to affirm the City of Concord’s commitment to the goals established in Resolution No. 26-__, adopted by the City Council on May 12, 2026, which adopts the Comprehensive Safety Action Plan (CSAP) and commits the City to a Vision Zero goal of reducing traffic-related fatalities and severe injuries (also referred to as serious injuries under the Safe Streets and Roads for All program) on City streets by fifty (50) percent by the year 2040, with the eventual goal of eliminating all such fatalities and severe injuries on City streets by the year 2050.

The CSAP responds to a documented and significant roadway safety pattern. Between 2021 and 2025, the City of Concord recorded 1,804 injury collisions, including 164 incidents resulting in fatalities or severe injuries, and 19 fatalities. The CSAP provides a data-driven framework grounded in the Safe System Approach to address this pattern. The Plan draws on a five-year collision review using SWITRS and TIMS data, identifies a High Injury Network where the most significant safety needs are concentrated, and selects FHWA Proven Safety Countermeasures appropriate to local roadway conditions.

As City Manager, I am directing City staff to implement the CSAP through a coordinated, multidisciplinary effort that integrates engineering improvements, education and outreach, enforcement coordination, emergency response collaboration with public safety partners, and post- crash care. Implementation will include sustained interagency coordination with regional, State, and Federal partners, including the Contra Costa Transportation Authority, the Metropolitan Transportation Commission, and the California Department of Transportation, as well as coordination with adjacent jurisdictions and roadway owners on shared corridors and facilities within or affecting the City.

The CSAP was developed through a comprehensive public engagement process. The City conducted three multi-agency Steering Committee meetings with representatives from BART, County Connection, the Contra Costa County Fire Protection District, and the Mount Diablo Unified School District; three public community outreach meetings; a citywide online safety survey that generated 651 responses; a web-based map input platform that collected 77 location-specific comments; and a presentation to the Bicycle and Pedestrian Advisory Committee. This process produced a Plan that reflects the safety priorities of the broader Concord community and its institutional partners.

Building on this foundation, the City of Concord intends to pursue Federal funding under the Safe Streets and Roads for All (SS4A) Implementation Grant program to advance the highest-priority projects identified in the CSAP, with non-Federal matching funds committed in accordance with applicable program requirements. To ensure continued accountability, City staff will conduct annual public reporting on progress toward reducing roadway fatalities and severe injuries and will maintain the CSAP publicly accessible online.

I extend my appreciation to the Mayor and City Council for adopting Resolution No. 26-__, to the multi- agency Steering Committee for its substantive contributions, and to the residents and businesses of Concord who participated in the engagement process. This effort reflects a shared commitment to safer streets for everyone who lives, works, learns, and travels in the City of Concord.

Sincerely,
City Manager, City of Concord

Dear Members of the Community,
On behalf of the City Council of the City of Concord, we reaffirm our commitment to the goals established in Resolution No. 26-__, which adopts the Comprehensive Safety Action Plan (CSAP) and commits the City to a Vision Zero goal of reducing traffic-related fatalities and severe injuries (also referred to as serious injuries under the Safe Streets and Roads for All program) on Concord streets by fifty (50) percent by the year 2040, with the eventual goal of eliminating all such fatalities and severe injuries by 2050. We adopted this resolution at our regular meeting on May 12, 2026.

The safety of every person traveling through Concord remains among the City Council’s highest responsibilities. Each fatality and severe injury represents a preventable loss to a family, a neighborhood, and the broader Concord community. Through the CSAP, the City Council has formalized a commitment to address these losses through proactive, data-driven, and coordinated action. The Plan focuses on the safety of all roadway users, including pedestrians, bicyclists, motorcyclists, motorists, transit users, children, older adults, and people with disabilities.

The City Council supports implementation of the CSAP through a Safe System Approach that recognizes that human error is inevitable but the consequences of that error do not have to be fatal. We have directed City staff to implement the strategies, programs, and projects identified in the Plan, and to assess relevant transportation policies, plans, design guidelines, and standards to identify opportunities to prioritize roadway safety in City operations and decision-making.

The City Council has authorized the City Manager, or her designee, to submit the adopted Plan to the Federal Highway Administration and the U.S. Department of Transportation, and to apply for, accept, and execute grant agreements under the Safe Streets and Roads for All (SS4A) Implementation Grant program and other Federal and State transportation safety funding to advance implementation of the CSAP. We acknowledge that achieving the Vision Zero goal requires significant and sustained effort, resources, and dedicated safety planning activities, and we are committed to allocating appropriate City resources toward this end.

To ensure ongoing transparency and accountability to the residents we serve, the City Council has directed staff to conduct annual public reporting on progress toward reducing roadway fatalities and severe injuries, to maintain the CSAP publicly accessible online, and to communicate findings to the City Council, partner agencies, and the public. Continued public engagement will remain central to this effort.

We commend the work of City staff, the multi-agency Steering Committee, and the residents, businesses, and stakeholders who contributed to the development of the Comprehensive Safety Action Plan. Their dedication has produced a foundation upon which the City Council, in partnership with our regional, State, and Federal transportation agencies, can advance meaningful safety improvements on the streets of Concord.

This Comprehensive Safety Action Plan (CSAP) was developed by the City of Concord with funding provided through a Safe Streets and Roads for All (SS4A) grant awarded by the Federal Highway Administration (FHWA), which is a testament to the City’s commitment to making its streets safer for every resident and visitor.

The CSAP builds on a strong foundation of prior planning work, including the Concord Bicycle, Pedestrian, and Safe Routes to Transit Plan (2016), the Complete Streets Feasibility Study for Willow Pass Road, Galindo Street, and Cowell Road (2020), and the Safe Trips to BART Action Plan (2025). It is further anchored in the principles of Vision Zero, the global movement committed to eliminating all traffic fatalities and severe injuries from our transportation network.

The City of Concord extends its sincere gratitude to the regional partner agencies and community organizations whose
engagement and expertise were indispensable in shaping this plan. The perspectives of stakeholders and community members across Concord ensured that the CSAP reflects the real safety needs and priorities of all residents, whether they travel by foot, bicycle, transit, or car.

The City of Concord is fully committed to implementing
the strategies set forth in this CSAP and to working in close partnership with its partner agencies to achieve the ultimate goal:
zero traffic fatalities and serious injuries on Concord’s streets.

The City of Concord’s CSAP was developed with the guidance and oversight of a multidisciplinary Steering Committee representing key municipal, regional, and institutional stakeholders. The committee provided strategic direction throughout the planning process, contributing expertise in public works, transportation, emergency services, transit operations, and school safety to ensure the CSAP reflects the diverse needs of the Concord community.

Concord Comprehensive Safety Action Plan

EXECUTIVE SUMMARY
SS4A ACTION PLAN COMPONENTS
The City of Concord has developed this Comprehensive Safety Action Plan (CSAP) in accordance with the requirements of the Safe Streets and Roads for All (SS4A) grant program administered by the U.S.

Department of Transportation. The CSAP is guided by the Safe System Approach and the City’s formal commitment to Vision Zero. Through a City Council Resolution adopted in May 2026, Concord has committed to reducing traffic-related fatalities and serious injuries by 50 percent by 2040, with the ultimate goal of eliminating all such outcomes on City streets by 2050.

The primary objectives of the CSAP are to:
• Conduct a comprehensive, data driven safety analysis of Concord’s transportation network for the period January 2021 through December 2025.
• Identify the City’s High Injury Network (HIN), comprising the corridors and intersections where fatal and serious injury (KSI) collisions are most heavily concentrated. • Develop a Safe Streets Toolkit of evidence-based countermeasures organized under the Safe System Approach to address identified collision patterns and systemic risk factors. • Identify and prioritize a portfolio of actionable safety projects and programs, including both systemic network-wide improvements and targeted interventions at high-injury corridors and intersections. • Establish a framework for implementation, performance monitoring, and funding to ensure sustained, accountable progress toward the City’s Vision Zero goals.

Between January 1, 2021 and December 31, 2025, a total of 1,804 traffic collisions were reported in Concord, of which 164 (approximately nine percent) resulted in KSI, including 19 fatalities and 145 severe injuries. The safety analysis culminates in the identification of the City’s HIN, comprising 15 high-priority corridors and 12 high-priority intersections. Clayton Road rank as the highest-priority corridor, followed by Monument Boulevard, Willow Pass Road, Concord Boulevard, and Treat Boulevard. Together, these corridors and intersections account for a disproportionate share of KSI outcomes citywide and form the spatial foundation for the CSAP’s safety investment strategy.

The CSAP was informed by an inclusive community engagement process encompassing an interactive map-based public survey, community workshops, and a multidisciplinary Steering Committee representing City departments, law enforcement, EMS, schools, regional transportation partners, and community advocacy organizations. Special efforts were made to reach historically underserved communities and to ensure that safety investments reflect both collision data and the lived experiences of all Concord residents. The resulting safety project portfolio spans systemic improvements that proactively address risk across the transportation network and targeted design projects at specific HIN locations, each documented with proposed countermeasures and planning-level cost estimates. Project prioritization weighs safety performance, benefit to vulnerable road users, and proximity to schools, disadvantaged population impacts, and ease of implementation.

The CSAP aligns with the Safe System Approach and the SS4A program requirements, and is intended to function as a living document updated every two to five years. Implementation will be coordinated with the City’s Capital Improvement Program and supported by partnerships with Caltrans District 4, CCTA, MTC, the Concord Unified School District, and law enforcement. Annual performance monitoring will track reductions in KSI collisions and implementation progress, with findings reported publicly to ensure accountability. Through this commitment, the City of Concord aims to serve as a model for other Bay Area communities in achieving the goal of zero traffic fatalities and serious injuries.

CHAPTER ONE

Concord Comprehensive Safety Action Plan

The City of Concord is the largest City in Contra Costa County and a major regional hub within the San Francisco Bay Area.

Incorporated in 1905 as an agricultural community, Concord experienced substantial residential and commercial growth following the launch of Bay Area Rapid Transit (BART) service in 1973. With a 2020 U.S. Census population of approximately 125,410 residents and a total area of approximately 30.5 square miles in central Contra Costa County, Concord has developed into a significant regional center for commerce, employment, and transit.

As a general law city under California state law, Concord’s transportation responsibilities encompass planning and
maintaining the local street network, delivering capital improvement projects, and ensuring compliance with federal and state requirements related to transportation planning and environmental justice. The City maintains close coordination with the Contra Costa Transportation Authority (CCTA) which is the county’s Congestion Management Agency as well as with the Metropolitan Transportation Commission (MTC), Caltrans District 4, and BART on the full range of regional transportation priorities.

Concord’s transportation network is shaped by its
predominantly suburban land use pattern, where more than 70 percent of parcels are devoted to single-family residential uses and commercial activity is concentrated along principal arterials. The City’s most travelled corridors, namely Monument Boulevard, Clayton Road, Willow Pass Road, Galindo Street, Salvio Street, and Concord Boulevard form the backbone of daily movement for tens of thousands of residents. Two BART stations anchor the multimodal network: the Concord Station adjacent to the historic downtown, and the North Concord/ Martinez Station along Port Chicago Highway, both of which serve as critical destinations and transfer points for commuters and residents alike.

Traffic safety is not an abstract policy objective, but it is a direct expression of a community’s values. Every fatality on a public road represents a preventable loss; every severe injury carries consequences that ripple through families and communities for years. Despite sustained investment at the federal, state, and local levels, traffic- related collisions continue to exact an enormous toll in human suffering, economic cost, and diminished quality of life across California and the nation.

The consequences of traffic-related incidents are not borne equally across the community. Pedestrians, cyclists, older adults, children, and individuals with disabilities face a disproportionate share of fatal and serious injuries, and these impacts are most concentrated in communities that have experienced historic underinvestment in transportation infrastructure. In Concord, as in many Bay Area cities, these disparities are most pronounced along high-volume arterial corridors and in lower-income neighborhoods where residents depend most heavily on walking, cycling, and transit for their daily travel needs.

Improving transportation safety is both a civic responsibility and a practical foundation for building livable, sustainable, and inclusive communities. The Safe System Approach provides a proven framework for achieving this goal by shifting primary responsibility from individual road users to the design of the transportation system itself, ensuring that the network is forgiving of human error and that mistakes do not routinely result in death or severe injury. By embracing this approach, the City of Concord can achieve meaningful, lasting reductions in traffic-related fatalities and serious injuries while creating an environment that supports walking, cycling, and transit as safe and viable modes of travel.

The City of Concord recognizes that safe streets are fundamental to the health and vitality of its community. Through this CSAP, the City commits to a proactive, data-driven strategy for eliminating traffic fatalities and serious injuries that is grounded in evidence, guided by community need, and built for lasting impact.

The City of Concord is committed to improving safety across its entire transportation network, in alignment with the statewide goals established under California’s Strategic Highway Safety Plan and the principles of Vision Zero. With a clear recognition of the urgent need to reduce traffic fatalities and serious injuries, the City has set an ambitious but achievable goal: the reduction of traffic related fatalities and severe injuries on City streets by 50 percent by the year 2040, with the eventual goal of eliminating all traffic related fatalities and severe injuries on City streets by the year 2050.

The Concord City Council has formally adopted a Resolution committing to Vision Zero and endorsing this Comprehensive Safety Action Plan as the City’s roadmap for achieving that goal. The full text of the Resolution, together with the City’s Vision Zero policy commitment, is included in Appendix A. In adopting this resolution, the City affirms its resolve to serve as a regional leader in roadway safety, leveraging engineering solutions, sound policy, and sustained investment to fundamentally improve the safety of its streets.

This commitment reflects the City’s core value of prioritizing the safety and wellbeing of all Concord residents, regardless of how they choose to travel. To achieve its Vision Zero goal, the City will pursue a comprehensive, data-driven approach that addresses the full range of factors contributing to traffic collisions from engineering improvements at high-risk locations to education initiatives that promote safe road-user behavior and enforcement efforts that uphold traffic safety laws.

City leadership is fully committed to this vision and has dedicated the resources and institutional will necessary to drive meaningful, measurable progress. Ongoing performance monitoring, rigorous data analysis, and sustained stakeholder engagement will ensure that Concord remains on track toward its safety targets. Through this commitment, the City aims to serve as a model for other communities across the Bay Area and California in achieving the goal of zero traffic fatalities and serious injuries.

Concord Comprehensive Safety Action Plan

This regional roadway safety action plan was developed by the San Francisco Bay Area Rapid Transit District (BART). It is the first plan of its kind developed by a transit operator in the United States. Guided by the Safe System Approach, the plan analyzed five years of injury crash data (2019–2023) on public streets surrounding all 48 non-airport BART stations across five Bay Area counties to identify a system wide High Injury Network (HIN). The plan produced a four- tier Systemic Roadway Safety Measures Toolbox of more than 30 engineering countermeasures aligned with the FHWA Safe System Roadway Design Hierarchy, and developed Focus Station Area Action Plans (FSAAPs) for seven representative stations, including Concord.

The Five-Year Capital Improvement Plan (CIP) FY2025–FY2029, adopted by City Council in June 2024, provides the financial and programmatic framework for implementing CSAP strategies through capital investments in transportation infrastructure. The CIP evaluation criteria explicitly prioritize projects that implement Complete Streets policy goals and Climate Action Plan strategies, ensuring the systematic integration of safety considerations into all capital planning decisions.

The Contra Costa County Complete Streets Safety Assessment (CSSA), conducted by UC Berkeley SafeTREC, evaluates pedestrian and bicycle safety along Concord Avenue from Contra Costa Boulevard to downtown Concord.

The assessment applies the Safe System Approach, integrating safe road users, safe vehicles, safe speeds, safe roads, and post-crash care. Through crash data analysis, policy benchmarking, and field audits of three focus areas, the CSSA identifies infrastructure countermeasures including Leading Pedestrian Intervals, protected left turns, roundabouts, medians, and enhanced crossings.

The Concord FSAAP directly supports the CSAP by identifying six priority locations on HIN corridors. For each location, the FSAAP provides site-specific countermeasure recommendations organized by Safe System tier with capital cost estimates, offering a ready implementation framework consistent with the CSAP’s Safe System approach. The plan’s system wide finding that arterials and higher-speed roads disproportionately concentrate KSI collisions aligns directly with the CSAP’s goals of targeting investment on high-injury corridors. The plan also provides a documented regional evidence base the City can reference when pursuing federal and state safety grant funding to implement CSAP projects.

The CIP includes dedicated programs that directly advance CSAP objectives, including the School Safety Assessment Program addressing infrastructure conditions at all 50 schools citywide, the street lighting and safety improvement project, and the traffic safety and traffic calming program providing systemic solutions for high-risk areas. These programmatic investments complement project-specific safety improvements across the bicycle and pedestrian network, creating a comprehensive capital framework that translates the CSAP’s vision and goals into funded infrastructure improvements over the five-year planning horizon.

This assessment directly advances CSAP strategies by addressing crossing barriers at I-680 and SR-242, implementing traffic calming through lane narrowing, providing separated bicycle facilities, and enhancing signalized intersection safety. The CSSA’s alignment with the County Vision Zero Resolution adopted in December 2023 demonstrates the regional coordination essential to CSAP success.

The Pine Hollow Road Complete Streets Feasibility Study addresses a critical 2.2- mile corridor segment from Clayton Valley Charter High School to Mount Diablo Elementary School. The study was identified in the City’s Bicycle, Pedestrian and Safe Routes to Transit Plan (2016) as a priority corridor lacking continuous sidewalks or bike lanes and facing challenges from high traffic speeds, heavy truck traffic, and frequent collisions. The study conducted extensive stakeholder engagement, analyzed existing corridor conditions, and recommended innovative and context-sensitive multimodal improvements to enhance bicycle and pedestrian safety, improve auto circulation, enhance trail connectivity, and improve residential and school access.

The Concord Local Roadway Safety Plan (LRSP) provides a systematic, data- driven approach to identifying roadway safety issues and developing targeted countermeasures to reduce fatal and serious injury (KSI) collisions. The LRSP analyzed collision data, identified high-risk locations, and developed emphasis areas focused on Safe System elements including safe road users, safe vehicles, safe speeds, safe roads, and post-crash care. The LRSP establishes a framework to systematically identify and analyze safety problems and recommend improvements following the Safe System approach, which acknowledges that human error is inevitable and designs the road system to minimize the serious consequences of collisions.

The Complete Streets Feasibility Study, completed in February 2020 with Caltrans funding, develops design concepts for 2.4 miles of Willow Pass Road, 1.2 miles of Galindo Street, and 2.1 miles of Cowell Road. The study provides engineering analysis and community-driven recommendations applying complete streets principles including travel lane narrowing to 10–11 feet, widened sidewalks, separated bicycle facilities, curb extensions, green infrastructure, street trees at 25–30 foot spacing, and improved signal timing.

This feasibility study exemplifies the CSAP’s comprehensive approach to corridor safety by addressing multiple modes of transportation, prioritizing vulnerable users near schools, and incorporating community input into design solutions. The study’s focus on complete streets principles and accessibility improvements directly supports the CSAP’s Safe System approach and demonstrates the City’s commitment to the systematic evaluation and improvement of high-priority corridors identified through data analysis and community concern.

The LRSP serves as a critical foundation document for the CSAP, providing detailed collision analysis, proven countermeasures, and implementation roadmaps that directly support the CSAP’s goals. The CSAP builds upon the LRSP’s data-driven approach while expanding its scope to include comprehensive community safetyw analysis, and broader stakeholder and public engagement consistent with SS4A program requirements. The LRSP’s emphasis on Vision Zero principles and the Safe System approach provides the philosophical and technical foundation for the CSAP’s comprehensive safety strategy.

This study supports the CSAP through phased implementation leveraging existing CIP repaving projects, medium-term network connectivity improvements, and long-term road diets converting vehicle capacity to pedestrian and bicycle space. The community engagement process provides a model for incorporating resident priorities into CSAP implementation while addressing documented safety needs.

The Monument Corridor Community-Based Transportation Plan addresses mobility and accessibility challenges along a key corridor in the City of Concord. The plan identified several mobility goals, with community concerns focused specifically on bicycle and pedestrian safety. Users of active transportation are disproportionately affected by collisions in the study area.

Drawing on extensive public feedback, the plan recommends comprehensive actions to improve transportation safety, including Safe Routes to School improvements, enhanced crossings, traffic signal coordination, sidewalk gap closure, commercial driveway consolidation, separated bikeways, wayfinding signage, and volunteer driver programs.

The Bicycle, Pedestrian & Safe Routes to Transit Plan establishes a 20-year vision for improving the walking and bicycling environment throughout Concord.

To achieve a safe and efficient multimodal transportation system, the City recognizes that new streets will need to be developed and existing streets selectively retrofitted through road diets, lane narrowing, traffic calming, and other safety improvements. The plan places safety as its highest priority, developing project recommendations that address known safety challenges based on available collision data. The plan prioritizes travel safety for all modes of transportation and designs active transportation projects that are accessible and comfortable for people of all ages and abilities.

The Downtown Corridors Plan focuses on revitalizing Concord’s downtown area by enhancing three critical corridors: Oak Street, Grant Street from Oak Street to Salvio Street, and Salvio Street from Grant Street to Broadway. These corridors form the eastern half of the green frame conceptualized in the Downtown Specific Plan. The plan aims to improve key pedestrian and bicycle connections between Todos Santos Plaza, employment centers, residential neighborhoods, and regional transit. The design applies familiar materials while establishing more consistent standards, better legibility and accessibility, and improved safety for all users.

This community-based plan demonstrates the CSAP’s commitment to engaging directly with residents and addressing their specific safety concerns. The plan’s emphasis on protecting vulnerable users, particularly pedestrians and cyclists, aligns with Safe System principles and provides a model for comprehensive corridor improvements that balance multiple transportation modes while prioritizing safety. The plan’s recommendations for infrastructure improvements combined with educational and enforcement programs support the CSAP’s multifaceted approach to transportation safety.

This comprehensive plan provides the strategic framework for the CSAP’s active transportation safety goals.

The Transportation Element of the Concord 2030 General Plan, amended in 2015, provides comprehensive guidance to ensure that people and goods can safely and efficiently move within Concord and connect to the regional transportation system. The Element defines clear priorities within the transportation system, placing pedestrians and cyclists first and prioritizing pedestrian facilities above dedicated bicycle facilities, and both above street trees and parking. The Element incorporates complete streets policies as required by state law, recognizing that roads should be designed to meet the needs of multiple users including motorists, bicyclists, pedestrians, transit users, and persons of different physical capabilities.

The Concord Complete Streets Study provides comprehensive analysis and recommendations for implementing complete streets principles throughout the City. The study examined existing conditions, analyzed collision data from the Transportation Injury Mapping System (TIMS) for pedestrian and bicycle collisions, identified twelve target intersections for safety improvements, and developed specific design recommendations.

The Downtown Specific Plan, adopted in 2014 and amended in 2021, articulates a comprehensive vision to revitalize Downtown Concord and accommodate growth in future population and employment. As a designated Priority Development Area and BART Station Planning Area, Downtown Concord represents a critical opportunity for transit-oriented development. The plan contains specific circulation objectives including developing a green street framework, designing and constructing streets that integrate green streets principles supporting pedestrian, biking, transit, and green infrastructure, and improving access to and from the Downtown Concord BART Station.

This foundational planning document establishes the policy framework that guides all transportation planning and implementation in Concord.

The Element’s clear prioritization of vulnerable users, commitment to complete streets principles, and emphasis on multimodal transportation provide the overarching policy foundation for the CSAP. The specific policies addressing pedestrian circulation, bicycle network development, traffic calming, and safe routes to schools create the regulatory and planning framework necessary to systematically implement the CSAP’s comprehensive safety strategies while ensuring consistency with broader community planning goals.

This study provides detailed technical analysis and specific design solutions that support the CSAP’s implementation strategy. The study’s recommendations for establishing clear ADA accessibility plans, evaluating lower-volume streets as boulevards, implementing consistent bike lanes and sharrows, and creating programs to educate residents and foster a culture of active transportation directly inform the CSAP’s comprehensive approach. The collision data analysis and identification of high-priority intersections provide a data-driven foundation for targeting safety improvements where they are needed most.

This specific plan provides the land use and development framework that supports the CSAP’s comprehensive safety goals. By promoting higher- density, mixed-use development around transit stations and creating walkable, bikeable environments, the plan reduces vehicle miles traveled and creates opportunities for safe active transportation.

CHAPTER THREE

Concord Comprehensive Safety Action Plan

The analysis applied a range of complementary techniques to evaluate collision patterns and contributing factors across multiple The CSAP employs a systematic, data-driven methodology to evaluate roadway safety conditions across the City of Concord. Five years of collision records were analyzed to identify trends, recurring patterns, and contributing factors affecting all categories of road users. The findings directly inform the identification of priority safety concerns and the development of targeted, evidence-based countermeasures.

This chapter presents the results of the safety analysis conducted for the City of Concord as part of the Comprehensive Safety Action Plan (CSAP). Grounded in the Safe Streets and Roads for All (SS4A) program requirements and the Safe System Approach, the analysis provides the technical foundation for identifying high-risk locations, understanding systemic safety patterns, and guiding the selection and prioritization of countermeasures.

The analysis is structured around three primary components: (1) collision analysis, (2) High-Injury Network (HIN) identification, and (3) development of collision profiles.

Collision data were drawn from three primary sources: the Transportation Injury Mapping System (TIMS), the Statewide Integrated Traffic Records System (SWITRS), and records maintained by the Concord Police Department. Police reports were used to supplement and validate individual collision details. Together, these sources yield a five-year dataset spanning January 1, 2021, through December 31, 2025, a sufficiently robust timeframe to evaluate long-term safety trends, seasonal patterns, and location-specific risk concentrations.

Drawing on the results of the collision analysis, the City identified a High-Injury Network (HIN) is a defined set of roadway segments and intersections where fatal and severe injury collisions are disproportionately concentrated. The HIN serves as the primary tool for directing safety investments and prioritizing targeted interventions toward the locations where the potential to reduce serious harm is greatest.

Collision profiles were developed to characterize recurring patterns in roadway incidents, capturing key dimensions including collision severity, mode involvement, and contributing factors. These profiles deepen the understanding of systemic safety challenges and directly inform the selection of countermeasures suited to specific collision types and roadway contexts.

The California Office of Traffic Safety (OTS) publishes annual rankings that enable cities to benchmark their traffic safety performance against peers of comparable population. These rankings are produced using an Empirical Bayesian methodology that accounts for population size, vehicle miles traveled, and collision frequency, providing a statistically grounded basis for comparison.

For 2023, the most recent year for which OTS rankings are available, Concord’s results identify several areas warranting focused attention:
• Pedestrian collisions (age 65 and older): 4th out of 62 cities • Speed-related collisions: 15th out of 62 cities
• Hit-and-run collisions: 16th out of 62 cities
• DUI collisions (drivers under age 21): 18th out of 62 cities A full list of all categories is posted on California OTS’s website. These rankings serve as high-level indicators of safety performance and are considered alongside the City’s own local collision analysis to inform planning priorities and funding strategies.

Fatal and serious injury (KSI) collisions peaked in 2022, with 39 incidents recorded, which is the highest annual total in the five-year study period. Both 2021 and 2025 followed with 34 KSI collisions each.

Total injury collisions rose from 315 in 2021 to a five-year peak of 383 in both 2022 and 2024, before declining to 341 in 2025. This year-to-year variability reflects the complexity of roadway safety and reinforces the case for sustained, data- informed interventions rather than single-point responses.

KSI collisions are most frequent on Mondays and Sundays, with 28 incidents recorded on each day over the study period.

Total injury collisions follow a different distribution, peaking on weekdays, with Thursday recording the highest volume at 310 collisions, while weekend totals are lower, with 235 on Saturday and 206 on Sunday.

This divergence between weekday and weekend patterns
reflects differences in travel volume and trip purpose.

Weekday commuting drives higher overall collision counts, while severe collisions are distributed more evenly across all days of the week, indicating that high-speed or high-risk travel behaviors are not limited to peak commute periods.

Both KSI and total injury collisions are most frequent during the afternoon and early evening hours. The period between 2:00 p.m. and 5:00 p.m. records the highest activity, with 36 KSI collisions and 420 injury collisions over the five-year study period.

This concentration aligns with the combined pressures
of afternoon commuter traffic and school dismissal trips which is a period of elevated roadway demand that warrants focused safety measures and targeted enforcement during peak hours.

KSI collisions are most frequent in June, with 19 incidents recorded over the five-year period, followed by August and December with 17 each.

Total injury collisions are broadly consistent across the calendar year, though a seasonal pattern is evident: collision frequency rises during the warmer months of May through October. Monthly totals range from a low of 126 in February to a peak of 165 in both September and October.

This seasonal pattern likely reflects the increase in travel activity, including recreational trips and pedestrian
and bicycle use during warmer months. This pattern
underscores the value of heightened safety outreach and targeted interventions timed to peak travel periods.

Collisions were categorized by location type to distinguish between intersection-related and mid-block incidents. Consistent with standard practice, any collision occurring within 250 feet of an intersection was classified as an intersection collision.

Of the 1,804 reported collisions, 1,518 (84 percent) occurred at or near intersections, with the remaining 286 (16 percent) occurring along mid-block segments. This pronounced concentration at intersections identifies them as the primary locus of collision risk in Concord and a central focus for safety investment. The table below summarizes injury collisions by severity and location type.

Concord Comprehensive Safety Action Plan

Mode Collision Type
Passenger vehicles are the most frequently involved mode, accounting for 37 percent of KSI collisions and 71 percent of total injury collisions.

Vulnerable road users are significantly overrepresented in severe outcomes relative to their share of total collisions. Pedestrian-involved collisions account for 28 percent of KSI collisions while representing only 11 percent of all injury collisions. Bicyclists account for 13 percent of KSI collisions and 8 percent of injury collisions, and motorcyclists account for 19 percent of KSI collisions and 7 percent of injury collisions. In each case, the gap between KSI share and overall collision share reflects the heightened physical vulnerability of these road users in the event of a collision.

These results affirm the need for safety strategies that specifically address pedestrian, bicycle, and motorcycle safety, consistent with the Safe System Approach’s priority of protecting those most at risk of serious harm.

Broadside collisions are the most prevalent collision type, accounting for 29 percent of KSI collisions and 38 percent of all injury collisions, which shows a consistent pattern with Concord’s high concentration of collision activity at intersections.

Vehicle-pedestrian collisions account for 27 percent of KSI collisions which reflects the physical vulnerability of pedestrians and the severity of outcomes when they are involved in collisions. Rear-end collisions represent 25 percent of total injury collisions but only 10 percent of KSI collisions, indicating that while they are common, they tend to produce less severe outcomes than intersection-related conflict types.

Collisions involving vehicles striking fixed objects contribute 16 percent of KSI collisions and 9 percent of total injury collisions, representing a meaningful share of severe outcomes that warrants attention in roadway design and speed management strategies.

Taken together, these patterns point to the need for countermeasures that address intersection conflict, pedestrian exposure, and roadway departure risk, the three collision types responsible for the greatest share of fatal and severe injury outcomes in Concord.

Unsafe speed is the leading contributing factor in Concord collisions, associated with 14 percent of KSI collisions and 23 percent of all injury collisions. Traffic signal and sign violations are equally prevalent in severe collisions, contributing to 14 percent of KSI collisions and 16 percent of total injury collisions.

Improper turning movements account for 14 percent of KSI collisions and 15 percent of injury collisions, while automobile right-of-way violations contribute 11 percent of KSI and 13 percent of injury collisions. Driving under the influence (DUI) is implicated in 12 percent of KSI collisions and 8 percent of total injury collisions, which shows a disproportionate share given DUI’s share of all trips, underscoring its outsized role in serious collision outcomes.

Pedestrian violations account for 13 percent of KSI collisions, a figure that reflects the complexity of pedestrian-vehicle interactions and the shared responsibility between road users and system design in preventing serious outcomes.

The breadth and variety of contributing factors confirm that no single intervention will resolve Concord’s safety challenges. Effective improvement requires a coordinated combination of engineering measures, targeted enforcement, and public education, each addressing different behaviors and roadway conditions.

COLLISION BY VIOLATION CATEGORY
Violation Lighting
Most collisions occur during daylight hours, accounting for 56 percent of KSI collisions and 70 percent of total injury collisions, a reflection of the greater volume of travel that occurs in daylight rather than any protective quality of darkness.

Collisions under dark conditions with street lighting present a disproportionate risk: they account for 34 percent of KSI collisions while representing only 24 percent of injury collisions overall. This gap indicates that nighttime conditions meaningfully increase the severity risk of a collision even when street lighting is present, reinforcing the importance of roadway lighting quality, visibility enhancements, and treatments that reduce vehicle speeds during low-light hours.

Weather
The overwhelming majority of collisions occurred under clear weather conditions, with 88 percent of KSI and 85 percent of all injury collisions.

Cloudy conditions account for 7 percent of both KSI and total injury collisions, while all other weather conditions contribute a minimal share.

The data confirm that adverse weather is not a primary driver of collision risk in Concord. Rather, collisions are concentrated under the everyday travel conditions that most residents experience most of the time, which reinforces the importance of systemic infrastructure improvements that perform under normal operating conditions, not just edge-case scenarios.

COLLISION BY WEATHER CONDITION
Moto Vehicle
Motor vehicle-to-motor vehicle incidents account for the largest share of collisions, with 39 percent of KSI and 65 percent of total injury collisions, reflecting the dominant role of vehicle-to-vehicle conflict in Concord’s collision landscape.

Pedestrian-involved collisions are strongly overrepresented in severe outcomes: they account for 27 percent of KSI collisions while comprising only 10 percent of total injury collisions. Collisions with fixed objects similarly punch above their weight, representing 16 percent of KSI collisions against 9 percent of total injury collisions.

Bicycle-involved collisions account for 11 percent of KSI and 8 percent of injury collisions. Across all vulnerable road user categories, the data consistently show a gap between collision frequency and collision severity, a pattern that directly informs the Safe System priority of designing the transportation network to protect those most at risk.

Age Group
Over the five-year study period, a total of 2,385 individuals were involved in injury collisions within the City of Concord, resulting in 20 fatalities and 2,365 reported injuries. Of those injuries, 152 were classified as severe, 473 as visible, and 1,740 as complaints of pain.

Age and gender data were unavailable for 103 individuals. Among those with complete records, adults aged 20 to 29 account for the largest share of those involved, at 425 individuals (19 percent), followed by those aged 30 to 39 with 404 individuals (18 percent) and those aged 40 to 49 with 346 individuals (15 percent).

Gender distribution is broadly balanced, with males accounting for 51 percent and females for 49 percent of involved individuals.

The concentration of collision involvement among working-age adults aged 20 to 49 is consistent with their higher rates of driving and active transportation use. This age distribution should inform both outreach strategies and the design of safety improvements along corridors most heavily used by this population.

Concord Comprehensive Safety Action Plan

The collision analysis culminates in the identification of Concord’s High-Injury Network (HIN) corridors and intersections where fatal and serious injury collisions are most heavily concentrated. Consistent with SS4A guidance and Safe System principles, the HIN provides the spatial framework for prioritizing safety investments and directing resources to locations where the potential for impact is greatest.

Collision locations were mapped and spatially analyzed using ArcGIS to identify areas of elevated KSI and total injury concentration. Each location was evaluated on both collision frequency and severity to ensure that the resulting network reflects the full spectrum of safety risk rather than volume alone.

The output of this analysis is a prioritized list of high-injury corridors and intersections that forms the foundation for the safety project recommendations in Chapter 6 and guides the allocation of limited resources toward locations with the greatest demonstrated need.

The resulting composite Safe System
score for Clayton Road is 11.36.

With a composite score of 11.36,
Clayton Road ranks as the highest-
priority corridor in the network. This
ranking reflects both its substantial
share of fatal and serious injury
collisions and its elevated involvement
of pedestrians and bicyclists, precisely
the combination of factors the Safe
System scoring methodology is
designed to surface.

For Clayton Road, the observed collision data includes:
• Fatal and serious injury (KSI) collisions: 16
• Total injury collisions: 224
• Intersection-related collisions: 208
• Pedestrian-involved collisions: 18
• Bicycle-involved collisions: 20
To identify and prioritize high-injury locations, the City applied a weighted ranking methodology consistent with Safe System principles and FHWA guidance. The approach is designed to reflect the dual priorities of reducing the most severe collisions and protecting vulnerable road users.

The scoring model draws on five collision indicators: KSI collisions, total injury collisions, intersection- related collisions, pedestrian-involved collisions, and bicycle-involved collisions. Each indicator carries a weight that reflects its relative importance to overall safety performance.

KSI collisions carry the highest weight of 30, reflecting the Safe System imperative to eliminate fatal and severe outcomes above all else. Pedestrian and bicycle collisions each receive a weight of 20, consistent with the elevated severity risk these users face. Total injury collisions are also weighted at 20 to capture overall safety performance, while intersection-related collisions receive a weight of 10.

To enable fair comparison across locations of different sizes and volumes, each indicator value is normalized proportionally: the count at each location is divided by the citywide total for that indicator, then multiplied by its assigned weight. The five weighted components are summed to produce a composite Safe System score for each corridor and intersection.

The Safe System score is calculated as follows:

METHODOLOGY
EXAMPLE CALCULATION – Clayton Road (Rank A)
High Injury Network
Locations are ranked by their composite score, with higher scores indicating a greater concentration of severe collisions and a correspondingly higher priority for safety investment.

This transparent, data-driven framework ensures that safety resources are directed to the locations where they can achieve the greatest reductions in fatalities and serious injuries, directly fulfilling SS4A program objectives and the core principles of the Safe System Approach.

These values were normalized using systemwide totals:
• Total KSI collisions: 164
• Total injury collisions: 1,804
• Total intersection collisions: 1,518
• Total pedestrian collisions: 190
• Total bicycle collisions: 149
Each component was weighted and calculated as follows:
• KSI contribution: (16 / 164) × 30 = 2.93
• Injury contribution: (224 / 1,804) × 20 = 2.48
• Intersection contribution: (208 / 1,518) × 10 = 1.37
• Pedestrian contribution: (18 / 190) × 20 = 1.89
• Bicycle contribution: (20 / 149) × 20 = 2.68

Concord Comprehensive Safety Action Plan

Collision profiles distill five years of collision data into a set of clearly defined, recurring safety patterns within the City of Concord. Each profile captures a distinct type of collision risk and serves as the analytical basis for selecting targeted countermeasures in the Comprehensive Safety Action Plan (CSAP).

Drawing on collision records from January 2021 through December 2025, the City identified consistent patterns in collision type, contributing factors, road user behavior, and roadway characteristics. These systemic patterns are the focus of the profiles, supporting countermeasure selection that addresses both collision frequency and severity across the network.

The profiles are designed to deepen understanding of the underlying causes of injury collisions and to anchor safety decision-making in evidence. By synthesizing trends across collision type, violation category, travel mode, location context, and lighting conditions, they surface the most effective and context-appropriate safety strategies for each identified risk area.

Rather than organizing safety issues by roadway classification, Concord’s profiles are developed on a citywide basis. This approach captures the most prevalent and severe patterns across the entire transportation network and allows the City to address systemic challenges that cut across roadway types and geographic areas.

Each collision profile is structured around four elements:
• Total number of injury collisions, including those involving fatal and serious injury (KSI) • Key collision trends, including collision types, violation factors, location characteristics, and lighting conditions
• Primary travel modes involved, such as motor vehicles, pedestrians, bicyclists, and motorcyclists • A geographic representation illustrating the spatial distribution of collisions associated with the profile
Together, these elements provide a complete picture of each safety challenge and the evidence base needed to identify effective countermeasures.

The analysis identified ten priority collision profiles representing the most significant and persistent safety challenges on Concord’s roadway network:

Collectively, these ten profiles define the safety priorities that shape every subsequent element of the CSAP, from infrastructure investments and project selection to education campaigns and enforcement strategies. By aligning resources with the conditions and behaviors most strongly associated with fatal and serious injury outcomes, the City can ensure that every safety dollar delivers the greatest possible reduction in harm.

CSAP

Concord Comprehensive Safety Action Plan

The development of the Concord Comprehensive Safety Action Plan (CSAP) involved extensive community engagement and close collaboration with stakeholders and residents. Recognizing that traffic safety is a shared responsibility, the process prioritized input from community members, partner agencies, and local stakeholders to identify key concerns, validate technical analyses, and build support for recommended strategies. Incorporating lived experiences from those who use Concord’s streets daily is essential to both the safety analysis and the identification of priority projects.

The CSAP engagement program was designed to reach a broad cross-section of the community and included four primary components:

The following table summarizes all engagement activities.

OVERVIEW SUMMARY OF ENGAGEMENT AND OUTREACH ACTIVITIES

Concord Comprehensive Safety Action Plan

The Steering Committee was established as part of the Concord Comprehensive Safety Action Plan (CSAP) to provide technical oversight and stakeholder guidance throughout the plan’s development.

The committee brings together representatives from municipal departments, regional transportation agencies, emergency services, and local institutions to support a coordinated and collaborative approach to improving traffic safety in Concord.

The formation of the Steering Committee reflected the understanding that traffic safety is a shared responsibility that requires coordination across multiple agencies and disciplines. Representatives from the City of Concord Public Works Department, the Contra Costa Transportation Authority (CCTA), Bay Area Rapid Transit (BART), the Contra Costa County Fire Protection District, and the Mt. Diablo Unified School District were convened to contribute their expertise and perspectives. This structure allowed the City to draw on a broad range of institutional knowledge and resources to identify and advance strategies to reduce serious injuries and fatalities on Concord’s roadways.

During the preparation of the CSAP, the Steering Committee played a central role in providing policy direction and technical input. Members contributed insights related to infrastructure, transit operations, emergency response, and school travel safety, helping to develop a comprehensive understanding of Concord’s safety challenges. The committee’s diverse representation ensured that the action plan reflected a wide range of considerations, including capital improvements, corridor redesigns, education, enforcement, and emergency response coordination.

The following table lists Steering Committee members and their affiliated agencies.

A dedicated project website (concordsafestreets.org) was developed to provide residents with ongoing access to CSAP information throughout the planning process. The website served as a central hub for project materials, including a project overview, a preliminary collision analysis summary with an interactive collision map, links to the community survey and map-based input tools, and updates on the project schedule.

The website was promoted through City communication channels and partner agency networks to reach a broad cross-section of Concord residents and encourage participation in the planning process.

By providing accessible and up-to-date information, the website supported transparency and facilitated ongoing community engagement.

AGENCYREPRESENTATIVE

Concord Comprehensive Safety Action Plan

A web-based public map input platform was
made available to allow residents to identify
specific locations and corridors where they had
observed or experienced traffic safety issues.

The platform was open from March 11 to April 20,
2026.

A total of 77 map-based comments were
received during this period. Analysis of these
submissions resulted in 106 categorized safety
concern responses, as individual comments
often referenced multiple issue types. For
example, a single comment at a given location
might identify concerns related to speeding,
school safety, and inadequate street lighting,
with each concern categorized separately in the
analysis. All subsequent analysis in this section is
based on these 106 categorized responses.

The following map illustrates the locations of
all community input comments across the city.

Appendix E contains the complete log of map
input comments and their associated safety
concern categories.

Concord Comprehensive Safety Action Plan

An online community safety survey was administered citywide from March 11 to April 20, 2026, generating a total of 651 responses. The survey collected information on travel behavior, safety concerns, personal experiences with traffic incidents, school zone conditions, geographic priorities, and preferred safety improvements.

Key findings from the survey are summarized below. A complete tabulation of results, including cross-tabulation analyses by age, trip purpose, and collision experience, is provided in Appendix F.

COMMUNITY SAFETY SURVEY HIGHLIGHTS COMMUNITY SAFETY SURVEY: HIGHLIGHTS BY TOPIC Respondent
Profile
651 responses collected March 11 to April 20, 2026. 51 percent of respondents were aged 55 or older. 94 percent traveled primarily by personal vehicle, consistent with Concord's auto-oriented street network.

Top Safety
Concerns
Speeding (66 percent) and red-light running (60 percent) are the dominant concerns across all road user groups and represent the clearest, most consistent signal in the survey. Distracted driving (39 percent) and illegal or unsafe e-bike operations (24 percent) are the next most frequently cited concerns.

Pedestrian
Safety
Failure to yield at crosswalks (37 percent) and turning vehicle conflicts (32 percent) are the leading pedestrian safety concerns. Missing sidewalks (19 percent) and missing crossings (13 percent) indicate unmet infrastructure needs.

Bicycle Safety
Cyclists not following traffic rules ranked first (26 percent), followed by absence of bike lanes (18 percent), poor road conditions (15 percent), and no safe routes (12 percent). Multiple open-ended responses noted e-bikes operating on sidewalks, particularly near schools, and called for consistent enforcement of e-bike regulations.

Personal
Incident
Experience
74 percent of respondents reported direct personal experience with a traffic incident on Concord streets. Near-misses (30 percent) and witnessed collisions (30 percent) were most commonly reported, followed by direct collision involvement (11 percent). Only 26 percent reported no personal incident experience.

Time-of-Day
Risk
The afternoon period (3 PM to 6 PM) was the highest-risk window across all modes: 62 percent of drivers, 33 percent of pedestrians, and 26 percent of cyclists identified it as the most dangerous time. Morning commute hours (6 AM to 9 AM) and school hours were the next most-cited periods.

School Zone
Safety
72 percent of respondents expressed concern about school-area safety. Speeding near schools (41 percent), traffic backup at drop-off/ pick-up (36 percent), and double-parking blocking sight lines (29 percent) were the top driver issues. Drivers failing to yield to children (30 percent) and absence of a dedicated bike route to school (19 percent) were prominent pedestrian and bicycle concerns.

Priority
Improvements
Crash-prone intersections (54 percent) and commercial corridors (36 percent) were the most frequently selected geographic focus areas. Increased police enforcement (52 percent), pedestrian signal improvements (38 percent), and high-visibility crosswalks (34 percent) are the most requested interventions.

Behavior
Change
92 percent of respondents modified their travel behavior due to safety concerns. The most common adaptations were avoiding certain streets (32 percent), traveling more cautiously (30 percent), and avoiding certain times of day (30 percent). Corridors most frequently cited for avoidance included Ygnacio Valley Road, Clayton Road, and Treat Boulevard.

Key FindingTopic
Note: Survey data collected via the City of Concord CSAP public engagement platform, March 11–April 20, 2026. Total valid responses: 651. Survey used multi- select, single-select, and open-text question formats. Percentages for multi-select questions exceed 100% as respondents could select multiple options.

Concord Comprehensive Safety Action Plan

Engagement findings were directly integrated into the CSAP’s analytical and planning framework. Input from the community survey and map-based platform both corroborated and enriched the technical collision data analysis. Corridors most frequently identified by residents as areas of concern, including Willow Pass Road, Concord Boulevard, Treat Boulevard, and Monument Boulevard, align closely with the High Injury Network corridors identified through quantitative analysis. Consistent emphasis on issues such as speeding, intersection conflicts, crosswalk violations, and gaps in pedestrian and bicycle infrastructure across both engagement tools further reinforced these concerns as citywide priorities.

Steering Committee guidance helped ensure that engagement outcomes were interpreted within the context of existing plans, programs, and funding opportunities. This coordination supported the development of recommendations that were
feasible within the City’s capital improvement programming and grant funding framework. In addition, three community outreach meetings provided opportunities for the public to review and comment on draft findings and emerging project recommendations, allowing the planning team to refine
priorities through direct dialogue with residents prior to finalizing the CSAP.

HOW ENGAGEMENT & OUTREACH

INFORMED THE CSAP

KEY TAKEAWAYS
Enforcement is the most requested improvement across all contexts.

Speeding and red-light running are the most prevalent safety concerns.

Traffic safety issues are widely experienced by residents.

The afternoon peak period presents the greatest safety risk.

Residents are actively adapting their behavior in response to safety concerns.

It ranked as the top priority in every geographic category, including residential streets, intersections, school zones, and commercial corridors. Support for physical infrastructure improvements was also strong, with pedestrian signals and high-visibility crosswalks consistently ranking second and third.

These issues were cited across all road user groups and geographic areas, indicating that any effective safety strategy should prioritize these behaviors through both enforcement and engineering countermeasures.

Three out of four respondents reported having direct or indirect experience with a traffic incident on Concord streets, indicating that safety concerns are grounded in direct experience rather than perception alone.

Between 3:00 PM and 6:00 PM, the highest share of drivers, pedestrians, and cyclists reported elevated safety concerns. Targeting enforcement, signal operations, and school zone measures during peak periods would benefit the broadest range of users.

The 92 percent rate of behavioral changes, such as avoiding certain routes or shifting travel times, highlights a substantial, often unmeasured burden that extends beyond reported collision data. 1 2

Safe Street Toolkit

CHAPTER FIVE
CSAP

Concord Comprehensive Safety Action Plan

Consistent with SS4A guidance, the Toolkit supports a
multidisciplinary approach to safety that integrates Engineering, Enforcement, and Education strategies. While engineering countermeasures form the core of the Toolkit, complementary measures including targeted enforcement and public education campaigns are essential for addressing behavioral risk factors such as The Safe Streets Toolkit presents a comprehensive suite of safety countermeasures to support implementation of the CSAP. The countermeasures are drawn from evidence-based strategies identified by the Federal Highway Administration (FHWA), including the Crash Modification Factor (CMF) Clearinghouse and FHWA guidance documents related to roadway departure, intersection safety, and roadway safety analysis. A complete listing of FHWA Proven Safety Countermeasures is provided in Appendix X.

The Toolkit serves as a technical resource to guide the selection and application of safety treatments that address identified collision patterns and systemic risk factors across the City’s transportation network.

The Safe Streets Toolkit is designed as a flexible reference document rather than a prescriptive list of improvements. All countermeasures are supported by research and have demonstrated safety benefits; however, their applicability varies depending on site-specific conditions, community context, and implementation feasibility.

In accordance with the Safe System Approach, the Toolkit enables City staff to select context-sensitive countermeasures based on factors such as roadway characteristics, user needs, collision history, and available resources. Inclusion of a countermeasure in the Toolkit does not constitute a formal recommendation for implementation; rather, it provides a range of viable options to be considered during project development and design.

For ease of application, countermeasures are organized into the following categories:

Each countermeasure included in the Toolkit is characterized using a standardized set of evaluation criteria to support informed decision-making:

The Toolkit supports both location-specific and systemic safety improvements within Concord. By leveraging data from the High Injury Network (HIN) and broader collision analysis, City staff can identify appropriate countermeasures to address priority safety concerns while also proactively deploying treatments across similar roadway contexts.

The following sections present detailed descriptions of individual countermeasures and provide guidance on their applicability within the City of Concord.

COMPREHENSIVE SAFETY APPROACH

TOOLKIT PURPOSE & APPLICATION

ORGANIZATION OF COUNTERMEASURES

COUNTERMEASURE EVALUATION CRITERIA

APPLICATION IN CONCORD
speeding, impaired driving, distracted driving, and failure to yield.

Implementing these strategies will require coordination with law enforcement agencies, community organizations, and regional partners to ensure a comprehensive and effective response to identified safety challenges.

Signalized Intersections: Treatments applicable to
intersections controlled by traffic signals, including
signal timing modifications, enhanced signage and
pavement markings, and geometric improvements.

Collision Types Addressed: Identifies the types
of collisions the countermeasure is intended to
mitigate, such as all collisions, pedestrian and bicycle collisions, or nighttime crashes.

Unsignalized Intersections: Countermeasures
for stop-controlled or uncontrolled intersections,
including signal installation, roundabouts, and
improved signing and striping.

Crash Reduction Factor (CRF): Provides the expected
percentage reduction in collisions based on empirical
research and national studies.

Roadway Segments: Treatments designed to improve
safety along roadway corridors between intersections,
such as rumble strips, roadway lighting, guardrails, and geometric realignments.

Expected Service Life: Indicates the anticipated
functional lifespan of the countermeasure, typically
ranging from 10 to 20 years, before major rehabilitation or replacement is required.

Additional Countermeasures: Non-infrastructure
strategies, including education, enforcement, and
programmatic initiatives.

Systemic Implementation Potential: Assesses the
suitability of applying the countermeasure using a
systemic, risk-based approach across multiple locations, categorized as Very High, High, Medium, or Low.

Concord Comprehensive Safety Action Plan

Includes the installation of new
streetlights, upgraded lighting fixtures,
or the enhancement of existing
lighting to improve visibility for all road
users at intersections. This may involve
increasing the number of luminaires,
improving lighting levels, or adjusting
lighting patterns to enhance visibility
and safety for all road users.

Includes New LED lighting, signal back
plates, retro-reflective tape outlining
the back plates, or visors to increase
signal visibility, larger signal heads,
relocation of the signal heads, or
additional signal heads.

Includes adding phases, lengthening

SIGNALIZED INTERSECTION COUNTERMEASURES
Corridors that have a history of collisions
involving emergency response
vehicles. The target of this strategy is
signalized intersections where normal
traffic operations impede emergency
vehicles and where traffic conditions
create a potential for conflicts between
emergency and nonemergency
vehicles. These conflicts could lead
to almost any type of crash, due to
the potential for erratic maneuvers of
vehicles moving out of the paths of
emergency vehicles.

Intersections that do not currently have
a left turn lane or a related left-turn
phase that are experiencing a large
number of collisions. Many intersection
safety problems can be traced to
difficulties in accommodating left-
turning vehicles, in particular where
there is currently no accommodation
for left turning traffic. A key strategy
for minimizing collisions related to
left-turning vehicles (angle, rear-end,
sideswipe) is to provide exclusive
left-turn lanes and the appropriate
signal phasing, particularly on high-
volume and high-speed major-road
approaches.

Left turns are widely recognized as the
highest-risk movements at signalized
intersections. Providing Protected left-
turn phases for signalized intersections
with existing left turn pockets
significantly improve the safety for left-
turn maneuvers by removing the need
for the drivers to navigate through
gaps in oncoming/opposing through
vehicles.

Converting a signal to a mast arm
from a pedestal-mounted base
provides better visibility of intersection
signs and signals that aid the drivers’
advance perception of the upcoming
intersection. Visibility and clarity of the
signal should be improved without
creating additional confusion or
distraction for drivers.

Includes the installation of flashing
beacons (e.g., yellow beacons,
LED beacons) to alert drivers to an
upcoming signalized intersection or
stop sign. This provides drivers with
increased visual cues, allowing for
earlier identification of the upcoming
intersection and improved reaction

Collisions related to turning maneuvers
include angle, rear-end, pedestrian,
and sideswipe (involving opposing
left turns) type collisions. If any of
these crash types are an issue at an
intersection, restriction or elimination
of the turning maneuver may be the
best way to improve the safety of the
intersection.

The addition of LPI gives pedestrians
the opportunity to enter an intersection
3-7 seconds before vehicles are given
a green indication; only minor signal
timing alteration is required.

For signalized intersections that have
a significant crash problem, one
alternative to change the nature of
the intersection itself is to convert
the intersection into a roundabout.

Roundabouts can also be very
effective at intersections with complex
geometry and intersections with
frequent left-turn movements.

Installing pedestrian countdown
signal heads at signalized pedestrian
crossings with walk/don’t walk
indicators, particularly at locations
with a history of pedestrian-vehicle
collisions, provides pedestrians with
a countdown of remaining crossing
time, encouraging safer and more
timely crossing decisions.

Accessible pedestrian signals provide
information in alternative formats such
as verbal message, audible tones and
vibrating surfaces to communicate
information on the status of pedestrian
crossing (Walk, Flashing Don’t Walk,
or Don’t Walk) to people who are
visually impaired. Speech messages
and wayfinding tones aid in navigation
to the pedestrian push button and
to the far side of the street. Speech
messages also aid sighted pedestrians
by alerting them to the pedestrian
signal indication changing from Don’t
Walk to Walk, reducing instances of
late crossings. Messaging that includes
street names aids in wayfinding and
orientation.

Signalized Intersections with no
marked crossing and pedestrian signal
heads, where pedestrians are known to
be crossing intersections that involve
significant turning movements.

They are especially important at
intersections with (1) multiphase traffic
signals, such as left-turn arrows and
split phases, (2) school crossings, and
(3) double-right or double-left turns.

At signalized intersections, pedestrian
crossings are often safer when the left
turns have protected phases that do
not overlap the pedestrian walk phase.

Pedestrian Scramble is a form
of pedestrian “WALK” phase at a
signalized intersection in which all
vehicular traffic is required to stop,
allowing pedestrians/bicyclists to
safely cross through the intersection
in any direction, including diagonally.

Pedestrian Scramble may be
considered at signalized intersections
with very high pedestrian/bicycle
volumes, e.g. in an urban business
district.

Installing an advance stop bar
before the crosswalk at signalized
intersections with marked crossings,
particularly where significant bicycle
and/or pedestrian volumes are known
to occur, helps to improve driver
compliance with the red light and
enhance pedestrian safety.

A designated, painted box at signalized
intersections that offers bicyclists
a multi-stage process to safely and
more visibly make a left turn across an
intersection from a bike lane.

Overhead-mounted LED luminaires
that activate upon pedestrian
pushbutton press, providing
targeted crosswalk illumination
during pedestrian crossing phases.

Unlike static intersection lighting,
PPLS concentrates high-intensity
illumination directly on the crosswalk
zone only when a pedestrian is present,
providing a dynamic visual cue to
drivers that a pedestrian is actively
crossing. Particularly effective at
intersections with high percentages of
nighttime or dark-condition pedestrian
collisions. PPLS is most effective when
integrated with APS and LPI timing
to provide a coordinated pedestrian
safety package.

Extending the all-red clearance
interval adds additional time after
one phase ends and before the
conflicting phase begins, allowing
vehicles that entered the intersection
during the yellow change interval to
clear before cross-traffic receives a
green indication. This low-cost signal
timing adjustment is particularly
effective at wide intersections and
locations with a high proportion of
angle and red-light-running collisions.

It can be implemented with existing
signal hardware through controller
programming changes only.

AI-powered video analytics platforms
use computer vision and machine
learning to continuously monitor
intersection operations and detect
near-miss events, traffic conflicts,
and unsafe behaviors in real time.

These systems analyze multimodal
interactions between vehicles,
pedestrians, and bicyclists to generate
conflict heatmaps, identify root
causes of recurring safety issues,
and quantify risk before collisions
occur. Near-miss analytics provide a
proactive, data-driven foundation for
selecting and prioritizing engineering
countermeasures, validating the
effectiveness of implemented safety
treatments, and supporting grant
applications with quantitative safety
evidence. Systems can integrate with
existing traffic cameras or deploy
dedicated sensors, and typically
include automated signal performance
measures (ATSPM) and dashboard
reporting capabilities.

NON-SIGNALIZED INTERSECTION COUNTERMEASURES
Intersections that have a high
frequency of right-angle and left-
turn type collisions. Whether such
intersections have existing crash
patterns or not, a roundabout provides
an alternative to signalization.

The primary target locations for
roundabouts should be moderate-
volume unsignalized intersections.

Installing/upgrading larger or
additional stop signs or other
intersection warning/regulatory signs
at or prior to intersections will enhance
the ability of approaching drivers
to perceive them, improving driver
awareness and reducing the risk of
collisions.

Upgrading intersection pavement
markings, which typically includes the
addition of “Stop Ahead” markings,
centerlines, and stop bars, can improve
driver guidance, reduce confusion,
and enhance overall safety at the
intersection.

Advance pedestrian warning systems
are activated signs installed upstream
(typically 100–150 feet) of a marked
crosswalk to alert approaching drivers that
a pedestrian is actively in the crosswalk
ahead. Activated by pushbutton, passive
infrared detection, or radar-based
pedestrian sensing, these systems display
flashing W11-2 pedestrian warning signs
with “AHEAD” or distance supplemental
plaques and/or LED-enhanced border
lighting. They are especially effective
on multilane roads where a driver in a
far travel lane may not see a pedestrian
already crossing in front of a stopped
vehicle in a near lane (the “multiple-threat”
scenario). Per MUTCD guidance, advance
RRFBs may also be installed upstream of
the crosswalk to supplement the warning
when sight distance is limited. These
systems are applicable at both signalized
and unsignalized crossings and are distinct
from static pedestrian warning signs by
providing a dynamic, real-time alert only
when a pedestrian is present.

Unsignalized intersection locations
that have a crash history and have
no controls on the major roadway
approaches. However, 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.

Flashing beacons can reinforce driver
awareness of the Non-Signalized
intersection control and can help
mitigate patterns of right-angle
collisions related to stop sign violations.

Post-mounted advanced flashing
beacons or overhead flashing beacons
can be used at stop-controlled
intersections to supplement and call
driver attention to stop signs.

Installing flashing beacons as advance
warning, such as yellow beacons, to
call drivers’ attention to intersection
control signs, provides increased visual
cues and improves driver awareness of
upcoming intersections.

Curb Extensions (also called Bulb-outs)
extend the sidewalk into the parking
lane at intersections, narrowing the
effective street width and shortening
pedestrian crossing distances. This
countermeasure improves pedestrian
visibility by positioning waiting
pedestrians at the edge of the parking
lane, slows turning vehicle speeds by
reducing corner radii, and reduces
pedestrian exposure time when
crossing the roadway. Bulb-outs also
provide additional space for accessible
curb ramps and prevent parking
encroachment on crosswalks.

CHAPTER SIX
CSAP

Concord Comprehensive Safety Action Plan

Systemic projects consist of citywide initiatives designed to address recurring collision risk factors through consistent improvements across the transportation network. Rather than focusing on individual locations, these projects target common deficiencies that contribute to collisions throughout the city, such as pedestrian safety at signalized intersections and gaps in sidewalk infrastructure.

In Concord, systemic projects were identified based on recurring collision patterns observed in the five- year collision analysis. Community input reinforced these findings, with residents highlighting concerns related to pedestrian safety at signalized intersections and the need for improved and continuous sidewalks.

The systemic projects recommended in this CSAP include:

While systemic projects address network-wide risks, design projects focus on specific corridors and intersections where collision concentrations and operational challenges are more pronounced. These targeted improvements respond to unique roadway conditions, traffic patterns, surrounding land uses, and multimodal travel demands.

Design projects were identified through a detailed evaluation of collision history, roadway characteristics, and community-identified safety concerns. High-injury corridors and areas near schools were prioritized due to their disproportionate share of severe collisions and their critical role within the City’s transportation network.

The design projects recommended in this CSAP include:

This chapter outlines a comprehensive, data-driven strategy to reduce traffic collisions, including fatalities and serious injuries within the City of Concord. Guided by the principles of the Safe System approach and informed by detailed collision analysis covering the period from January 2021 through December 2025, the recommended projects translate identified safety challenges into targeted, implementable improvements.

The proposed location-specific countermeasures respond directly to documented collision trends, including a high incidence of broadside and rear-end collisions, unsafe speed-related violations, vehicle–pedestrian conflicts, nighttime visibility concerns, and traffic signal and/or sign violations at both signalized and unsignalized intersections. These recommendations also reflect priorities identified through stakeholder engagement and community feedback.

To effectively address these safety challenges, the CSAP organizes recommended improvements into two categories:

Together, these approaches provide a balanced framework that addresses both widespread risk factors across the transportation network and location-specific collision patterns along high-injury corridors and intersections. This strategy enables the City to strengthen overall network safety while prioritizing investments in areas where they will have the greatest impact.

The Concord Comprehensive Safety Action Plan (CSAP) identifies 16 proposed projects organized into four categories: High Injury Network (HIN) Corridor Improvements, Complete Streets and Active Transportation, Citywide Safety Programs, and Planning and Policy Initiatives. These projects are designed to address collision patterns observed citywide during the study period, with a focus on corridors and locations where injury data indicates elevated risk for all roadway users.

All projects are conceptual and will require further feasibility analysis, preliminary engineering, and environmental review to define final scope, design, and cost. Implementation is contingent upon securing funding for both design and construction phases, and project prioritization may evolve based on additional technical analysis, community input, and emerging funding opportunities.

These corridors and locations account for a significant share of injury and KSI (Killed or Seriously Injured) collisions within the City. Corridors identified along the High Injury Network represent a disproportionate share of all KSI collisions citywide, underscoring the need for focused safety investments.

Unlike systemic projects, which address risks across the broader network, design projects deliver targeted solutions at locations where data indicates elevated safety risks. These interventions aim to reduce both the frequency and severity of collisions while improving accessibility, connectivity, and overall user comfort.

Together, systemic and design projects form a comprehensive safety framework for the City of Concord.

Systemic projects address widespread collision risk factors across the transportation network, while design projects focus resources on high-injury corridors and intersections with documented safety concerns.

This integrated strategy ensures that safety investments are both proactive and responsive. Systemic improvements aim to prevent future collisions by addressing common roadway deficiencies, while design projects target locations with a demonstrated history of collisions. By combining detailed data analysis, engineering best practices, and community input, the City establishes a strategic roadmap for reducing fatalities and serious injuries across the transportation network.

High Injury Corridor Improvements (Monument Boulevard, Concord Avenue, Galindo Street, Willow Pass Road, Clayton Road) 1 Project 1 would deliver targeted safety improvements along five HIN-priority corridors: Clayton Road (SR-242 to Washington Boulevard), Monument Boulevard (Cowell Road to Mohr Lane), Willow Pass Road (I-680 to Avila Road), Concord Avenue (John Glenn Drive to Salvio Street), and Galindo Street (Salvio Street to Cowell Road). Potential improvements identified for further design evaluation include speed feedback signs, enhanced street and intersection lighting, pedestrian passive detection, leading pedestrian intervals (LPI), high-visibility crosswalks, ADA-compliant curb ramps, curb reconfiguration, sidewalk gap closures, access management medians, high-friction surface treatment (HFST), intersection safety analytics, protected intersection design, connected vehicle (C-V2X) technology, and emergency vehicle preemption (EVP GPS) at priority
intersections. Collectively, these five corridors are associated with 687 injury collisions over the study period, including 8 fatalities and 52 severe injuries.

Treat Boulevard Safety
Improvements 8
Project 8 would address the Treat Boulevard corridor (Winton Drive to Clayton Road, approximately

3.1 miles) through a combination of planning and physical improvements. Potential elements identified for design consideration include a complete street feasibility study and preliminary design, mast-arm signal head upgrades, sidewalk improvements and gap closures, HAWK signal installation, leading pedestrian intervals (LPI) corridor-wide, speed feedback signs, and curve safety treatments including high-friction surface treatment (HFST) and warning beacons. Evaluation of a bicycle and pedestrian connection between San Miguel Road and Marietta Circle is also identified for further study. This corridor is associated with 76 total injury collisions over the study period, including 5 pedestrian-involved, 5 bicycle-involved, and 1 bus-involved collision.
