Executive Summary
The objective of the City of San Pablo Local Roadway Safety Plan (LRSP) is to establish a safe transportation environment that has safer roads, safer people, safer speeds, and safer vehicles.
As part of this safety plan for the City of San Pablo, Minagar & Associates, Inc. identified, prioritized, and analyzed roadway safety improvements on the City of San Pablo’s intersections and roadway segments. This safety plan also provides the proposed countermeasures to ultimately reduce collisions in the City’s high collision locations. From January 1, 2018 until December 31, 2022, there were a total of 1,823 collisions that included 13 fatalities and 800 injured victims. The most common types of collision were Rear End (553), Sideswipe (460), Broadside (260), and Hit-Object (224) Collisions. Primary Collision Factor (PCF) violations that caused the most collisions were Unsafe Speed (543), Improper Turning (269), and Unsafe Lane Change (237), and Victims were mostly drivers (473) and passengers (212). There have been 87 collisions involved with pedestrians. Within the jurisdictions of San Pablo’s local roadways, of the 1,823 collisions, 617 collisions were on state highways while 1,206 collisions were on local roadways. The highest number of victims happened to be in the age range of 20 to 24 years old. The Local Road Safety Plan is a major element to ameliorate transportation and traffic safety within a city. This LRSP was prepared and developed in compliance with the State and Federal guidelines for eligibility to apply for the funding of Highway Safety Improvement Program (HSIP). In addition to the provided countermeasures for collision patterns, this Safety Plan also provides the corresponding cost estimates and benefit-cost ratios, to support applications for the Highway Safety Improvement Program (HSIP).

1. Introduction
The City of San Pablo is taking the initiative to improve the City’s traffic safety by implementing a Local Roadway Safety Plan that aims to reduce traffic collisions by analyzing the factors that previously impacted prominent intersections and roadway segments in the City. This report documents the City of San Pablo’s work to assess and improve transportation safety conditions.
In this Safety Plan, a systemic approach was utilized to identify and analyze collision patterns that had impacted high collision intersections and roadway segments. For each high collision location, whether it was an intersection or a roadway segment, a table of number of collisions with the corresponding primary collision factor has been provided to understand the prominent collision factors. As part of the collision analysis, collision diagrams have been provided for high collision intersections and roadway segments in the City of San Pablo.
Following the understanding and acknowledgement of collision patterns, countermeasures for each of the identified high collision intersections and roadway segments were developed to potentially reduce traffic collisions in the future and ameliorate active transportation within the City. Furthermore, this Local Roadway Safety Plan includes collision data for high collision locations between January 1, 2018 and December 31, 2022, the analysis of collision data, and the proposed countermeasures for collision patterns. Depicted below in Figure 1 is the Local Road Safety Plan process provided by the Federal Highway Administration (FHWA).

2. Vision and Goals
The objective of this plan is to strive towards a safer transportation environment by analyzing crash data and implementing countermeasures to eliminate traffic fatalities and severe injuries while assuring efficient and equitable mobility for all road users. The City of San Pablo plans to implement systemic countermeasures to target factors affecting citywide prominent intersections and roadways segments. This safety plan aims to reduce the risk of tragedies by taking a proactive, preventative approach that prioritizes traffic safety.
Vision Zero is an initiative approach to eliminate traffic fatalities and severe injuries. However, road users will sometimes make mistakes.
Therefore, the road system, traffic control devices, and traffic laws should be designed to minimize those unavoidable mistakes and reduce their probability to result in severe injuries or fatalities.
Transportation and traffic engineers are expected to improve the general traffic environment by ameliorating existing traffic geometries and laws based on a good engineering judgement.
However, the roadway users of the City of San Pablo are still responsible for their mistakes and should follow all traffic laws.
Vision Zero identifies stakeholders to address
the factors causing collisions when it comes to
traffic safety. It recognizes that many factors
contribute to safe mobility including roadway
design, speeds, behaviors, technology, and
enforced laws. As a result and as part of this
safety plan, it sets goals to achieve zero
fatalities and severe injuries.
One of the City’s visions is to collaborate
with local agencies to promote a culture of
continuous transportation safety
improvement by coordinating with San
Pablo Police Department, Contra Costa
Public Health, and West Contra Costa
Unified School District.
The aforementioned Vision shall eliminate traffic fatalities and severe injuries by achieving the following goals:
• Obtain accurate collision databases. Systematically identify and prioritize the City’s highest collision locations based on a 5-year collision history. • Engage with the local community, stakeholders, and City management to better understand factors that are affecting the traffic safety within the City of San Pablo. • Utilize countermeasure strategies across all traffic safety disciplines, engineering, enforcement, education, emergency medical services, and emerging technologies. • Strive to reduce the City’s primary contributing factors in traffic collisions by ensuring the automobile right of way, maintaining a safe speed, and clear traffic signals and signs.

4. Process
This section describes the steps involved in preparing the safety plan, including a systemic approach that involves the analysis of collision data to identify high crash locations and prioritize countermeasures.
4.1 Systemic Approach
The systemic approach in preparing the safety plan comprises the following steps:
I. Develop Plan Goals and Objectives
Review the City’s existing planning documents to ensure the LRSP visions and goals align with planning effort and that the potential 5Es: Engineering, Education, Enforcement, Emergency Medical Services, and Emerging Technologies are consistent with local traffic safety and policies.
II. Analyze Collision Data
Obtain the latest 5-year collision data and analyze the collision factors. Determine high-risk intersections and roadway segments and identify significant risk factors.
III. Determine Focus Areas and Identify Crash Reduction Measures Identify emphasis areas and recommend feasible countermeasures at high-risk locations.
Evaluate Crash Reduction Factor (CRF) and the effectiveness of each countermeasure.
IV. Prioritize countermeasures/projects
Conduct Benefit-Cost Ratio (BCR) analysis on all countermeasures and projects. Prioritize projects that are most beneficial to the City’s roadway and intersection safety using BCR.
V. Prepare the Local Roadway Safety Plan
Prepare the LRSP that includes effective and efficient measures and implementation plan.
Identify priority projects for state or federal programming, grant funding opportunities, and implementation.

5. Existing Efforts
This section summarizes the findings from various planning documents for the City of San Pablo. The purpose of reviewing existing planning efforts is to ensure the LRSP goals and objectives along with recommended improvements are aligned with recent planning efforts for transportation safety.
The City of San Pablo has identified several goals and policies from the following documents:
• City of San Pablo Bicycle and Pedestrian Corridor Study (2022) This Report builds upon the recommendations and findings of previous planning efforts concerned with walking and bicycling (active transportation) in San Pablo, most notably the 2017 San Pablo Bicycle and Pedestrian Master Plan (BPMP). This Corridor Study is the result of over a year of robust community engagement and detailed analysis of existing conditions. By using this Report as a blueprint, the City will be well equipped to expand its active transportation network, thereby providing residents with comfortable, convenient, and healthy
alternatives to driving.
• City of San Pablo Safe Routes to School Master Plan (2022) The purpose of this Safe Routes to School Master
Plan (SR2S Plan) is to identify ways to make walking
and bicycling safer, more comfortable, and more
enjoyable for students, families, and school staff in
San Pablo. Safe Routes to School (SR2S) is an
international movement that uses programming and
infrastructure to improve safety and encourage
students to walk and bicycle to school. This
evaluation was centered around virtual and in
person walk audits that allowed students, families,
teachers, and principals to document their experiences walking and bicycling to school.

6. Data Analysis and Summary
This section summarizes the results of a citywide collision analysis for the time period between January 1, 2018 and December 31, 2022. The purpose of studying the collision patterns and trends is to identify the factors that caused collisions to occur within the study timeframe. The focus is to identify high crash locations in the City in order to target the factors that are affecting these prominent locations.
As part of the City’s Local Roadway Safety Plan, data that displays collisions on State Routes or Interstate Freeways will be part of the overall data presentation. However, countermeasures on intersections and roadway segments will be performed only on San Pablo’s local roadways.
Therefore, data used and analyzed on the selection of top intersections and roadway segments will be 100% within city boundaries and on local roads.
6.1 Overall Summary
According to the California Highway Patrol (CHP) Statewide Integrated Traffic Records System (SWITRS) as of June 23, 2023, during the period of January 1, 2018 to December 31, 2022, there were 1,823 collisions in total, where collisions included fatal, serious injury, visible injury, complaint of pain, and property damage only (PDO). In regards to location, 1,206 collisions occurred on local roadways and 617 occurred on state highways. Of the total number of crashes that happened, there were 13 victims killed and 800 victims injured. There were 87 pedestrian collisions, 34 bike collisions, and 41 motorcycle collisions. Maps from the University of California, Berkeley Transportation Injury Mapping System (TIMS) displaying Non-PDO collisions by point as well as by cluster are shown in Figures 2 and 3 respectively.

_____________________________________________________________________________________ 48 MINAGAR & ASSOCIATES, INC.
The City of San Pablo with a composite score of 8/91 with 68 victims killed or injured (Below 25%) is below average in comparison to other incorporated cities with similar population in the most recent OTS ranking as of 2020. Based on “Types of Crashes”, total fatal and injury resulted to be 78 victims killed or injured, which ranked 44/91, which places the city below 50%.
The City of San Pablo performed poor in speed related crashes with 15 fatal or injury crashes, ranking the City 28/91. Nighttime (9:00pm to 2:59 am) crashes has 12 fatal or injury crashes, ranking the City 19/91. There were also 15 fatal or injury hit and run crashes that ranked the City 13/91 (Bottom 14%).
Number 1 in the rankings is the highest, or “worst.” For example, a ranking of 1/74 is the highest or worst, 45/74 is average, and 74/74 is the lowest or best. The OTS Rankings were developed so that individual cities could compare their city’s traffic safety statistics to those of other cities with similar-sized populations. Cities could use these comparisons to see what areas they may have problems in and which they were doing well in. The results helped both cities and OTS identify emerging or on-going traffic safety problem areas in order to help plan how to combat the problems and help with the possibility of facilitating grants. It should be noted that OTS rankings are only indicators of potential problems; there are many factors that may either understate or overstate a city/county ranking that must be evaluated based on local circumstances. City rankings are for incorporated cities only, for local streets in those cities, and state highways that run through cities with shared jurisdiction with the CHP and the city.
Crash rankings are based on the Empirical Bayesian Ranking Method, which adds weights to d
ifferent statistical categories including observed crash counts, population and vehicle miles traveled. The crash counts reflect the aggregated impacts of all influential factors containing even the unrecognized or unmeasurable ones (e.g. level of enforcement). The population and vehicle miles traveled represent the important traffic exposure factors that affect crash occurrence. Counties are assigned statewide rankings, while cities are assigned population group rankings. In Table 3, Population – estimates matched to “Year”. DVMT – Daily Vehicle Miles Traveled. Caltrans estimate of the total number of miles all vehicles traveled on that city’s streets on an average day during that year. The number of cities in each group varies by year.
Cities are grouped by 2020 population: Group A – 15 cities, populations over 250,000, Group B – 61 cities, population 100,001-250,000, Group C – 106 cities, population 50,001-100,000, Group D – 91 cities, population 25,001-50,000, Group E – 103 cities, population 10,001-25,000, Group F – 74 cities, population 2,501-10,000, Group G – 32 cities, population 1-2,500. City of San Pablo is in Group D with an average population of 31,793. • Type of Crash – This column delineates the different types of crashes OTS has chosen to show in the rankings.

8. High Collision Locations Identification, Pattern Analysis, and Recommended Improvements
As part of the quantitative analysis, high collision intersections and roadway segments were identified and prioritized using the Crash Frequency methodology as described in the Local Roadway Safety Manual. Crash Frequency is defined as the number of crashes occurring within a determined study area. Minagar & Associates, Inc. took a further step and included the number of victims and their corresponding degree of injury for each intersection and roadway segment. Conceptual plans were developed and updated with these safety countermeasures.
For each of the identified high collision locations (intersections and roadway segments), prominent locations in the City were identified and ranked based on the following criteria:
1. Number of Collisions
2. Victim Degree of Injury
2.1. Killed
2.2. Suspected Serious Injury
2.3. Suspected Minor Injury
2.4. Possible Injury
2.5. Property Damage Only
Upon identifyi
ng and ranking prominent intersections and roadway segments, collisions were analyzed by identifying the Primary Collision Factor (PCF). Upon completion of the analysis, recommendations were developed as safety mitigation measures to potentially mitigate similar collisions in the future. Countermeasures have been proposed in complaince with the California Manual on Uniform Traffic Control Devices. It is important to utilize Crash Modification Factor (CMF) when identifying potential systemic safety improvements. The CMF method is found in Part D of the American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM). CMFs are defined as the ratio of effectiveness of expected crashes with treatment in comparison to expected crashes without treatment. Furthermore, CMF is a multiplicative factor used to determine the expected number of crashes after implementing the proposed countermeasures.

Countermeasures with CMFs less than one are expected to reduce crashes. On the other hand, countermeasures with CMFs greater than one are expected to increase crashes. CMFs are calculated as follows:
A Crash Reduction Factor (CRF) is similar and related to a CMF but stated in different terms. A CRF is defined as a percentage of crash reduction that might be expected after the implementation of a given countermeasure at a specific site. CRFs are calculated as follows:
Appropriate CMFs shall be used with caution. CMFs should be selected from the Highway Safety Manual (HSM) Part D, the Local Roadway Safety Manual (LRSM), or from the Federal Highway Administration (FHWA) Crash Modification Factor (CMF) Clearinghouse website (http://www.cmfclearinghouse.org
).

9. Collision Diagrams, Preliminary Conceptual Plans for Recommended Improvements at High Collision Intersections and High Collision Roadway Segments, Cost Estimates, and Benefit Cost Ratios
At each of the aforementioned high collision intersections and roadway segments, the collision patterns have been evaluated and countermeasures to those patterns have been developed through a preliminary conceptual plan and the preliminary cost of those measures has been estimated. This section of this report summarizes those results.
This Highway Safety Improvement Program (HSIP) is a federal program that aims to reduce traffic fatalities and serious injuries on all public roads. The HSIP uses a data-driven approach to improve highway safety. HSIP grant funding is prioritized and awarded based on the grant funding's economic effectiveness, which is established by a benefit to cost ratio. Under the most recent HSIP Cycle 11 call for projects, the minimum Benefit to Cost Ratio is 3.5. A summary of the benefit to cost ratios is provided in this section. Project cost estimates are calculated on a line-item basis using the Caltrans Contract Cost Database. In some cases, recent construction bids and benefit values are calculated based on Caltrans established countermeasure values. A summation of the total construction cost of all intersections and road segments are displayed at the end of the report.
The cost estimate used in this analysis is used to develop benefit to cost ratio comparison for concept plans and do not reflect actual cost of implementation or construction.
Depending on the City’s priorities, it is highly recommended that multiple projects as provided below are grouped into one HSIP application to maximize potential funding allocations.
