Executive Summary
The City of Rohnert Park was awarded a state grant from Caltrans to develop a Local Road Safety Plan
(LRSP). The LRSP is a requirement for Cycle 11 of the Highway Safety Improvement Program (HSIP)
grant funding. The LRSP includes a citywide analysis of the roadway system in Rohnert Park comprising
of the current collision patterns and high-risk roadway characteristics (systemic analysis). Rohnert Park’s
goal is to identify safety countermeasures to help mitigate the City’s primary crash type trends and reduce
the overall collision severity.
The LRSP is a collaborative process with representatives for the 5 E’s . The 5 E’s of traffic safety
include Engineering, Enforcement, Education, Emergency Response, and Emerging
Technologies.
This holistic approach allows certain areas of concern not showing a crash pattern to be analyzed. Also, it
fosters local, state, and agency partnerships to advance local road safety.
In following the overall LRSP process, a Stakeholder Working Group (Working Group) was formed with
the City as the lead and local organizations with an interest in improving the City’s roadway safety. This
group gathered for meetings to discuss the overall collision analysis, goals, priorities, safety
recommendations, and overall development of the safety plan.
Based on the past 6 years collision analysis and the City’s Stakeholder Working Group Meetings, this
LRSP will address multiple Strategic Highway Safety Plan (SHSP) Challenge Areas including, but not
limited to:
1. Bicyclists
2. Distracted Driving
3. Aggressive Driving / Speed Management
4. Intersections
5. Pedestrians
In addition, a vision, a mission statement, and goals were established during the development of the
LRSP. It was also decided that the LRSP for the City of Rohnert Park would be a living document with a
recommended formal update every five (5) years.
The following strategies are recommended for the focused study locations and Citywide systemic
applications for the 5 E’s of Traffic Safety.
1. Engineering: Apply safety countermeasures at current locations experiencing collisions and
systemically at locations with similar risks (comprehensive approach).
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan iii
2. Enforcement: Enforce actions that reduce high-risk behaviors to include speeding, distracted
roadway usage, and Driving Under the Influence (DUI).
3. Education: Educate all road users on safe behaviors.
4. Emergency Response: Improve emergency response times and action.
5. Emerging Technologies: Utilize emerging technologies in conveying and collecting information from
the roadway users to improve safety and operations.
Through collision data analysis, public input, and City feedback, priority locations were identified in the
City. These locations, along with their proposed engineering countermeasures, are shown in the tables
below.

1. Introduction
The Local Road Safety Plan (LRSP) is a traffic safety planning document for local agencies to address
unique roadway safety needs in their jurisdictions. This comprehensive document will both help to guide
the City’s implementation of safety countermeasures and allow eligibility for funding in future Highway
Safety Improvement Program (HSIP) grant applications.
Preparing an LRSP facilitates local agency partnerships and collaboration, resulting in a prioritized list of
improvements and actions that contribute to California’s Strategic Highway Safety Plan (SHSP) overall
vision and goals. This SHSP focuses on reducing fatal and severe injury collisions (FSI collisions) with
focused challenge areas with a focus on the Five “E’s” of Traffic Safety (see Figure 1).
Figure 1 California SHSP (2020-2024)
The City and GHD will follow the Federal Highways Administration’s (FHWA) Local Road Safety process
in the following six (6) steps as shown in Figure 2:
Figure 2 FHWA’s LRSP Development Process
In working with the first step of establishing leadership, Jason Sampietro (Project Manager) and Terrie
Zwillinger (Public Works Capital Improvement Project Program Manager) served as Safety
Champions/Leads for this project with a stakeholder working group that consisted of the other E’s
(enforcement, education, emergency response, and emerging technologies) and other important safety
partners. This stakeholder working group was paramount in creating a comprehensive safety plan tailored
to address the local needs and issues.
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 2
2. Background
2.1 Purpose and Need
The City of Rohnert Park is located in Sonoma County, south of Santa Rosa, California with an
approximate population of 42,000. Rohnert Park shares its southwestern border with the City of Cotati.
US Highway 101 crosses through the City in the north-south direction and provides two interchanges in
Rohnert Park: at Golf Course Drive and at Rohnert Park Expressway. Rohnert Park Expressway connects
US 101 to Sonoma State University and is a major thoroughfare through the City.
Focusing in on the roadway safety needs, the past six (6) years of collisions (2015-2020) were evaluated
for City roadways and Caltrans interchange locations. As presented in Figure 3, there were three fatal
and thirty-six severe injury collisions on City roadways. Caltrans interchange locations did not have any
fatal or severe injury collisions within this time period. In improving roadway safety for the City of Rohnert
Park, it is important to focus on mitigating these high injury collisions. More information on these collisions
can be found in Section 4.2: Collision Data.
Figure 3 High Severity Collisions in the City of Rohnert Park
2.2 Guiding Documents
FHWA requires that each state has an SHSP to receive federal funding. The California SHSP is a
statewide safety plan that helps provide a framework to reduce fatal and high severity collisions. Sonoma
County recently completed a countywide Vision Zero Action plan with similar goals (for more information,
see Section 2.2.2). In 2020, the Sonoma County Transportation Authority procured seven (7) LRSPs
throughout Sonoma County. These LRSPs will have similar goals to the California SHSP and Sonoma
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 3
County Vision Zero but will be more tailored to the local roadway needs of each agency.
2.2.1 California Strategic Highway Safety Plan
The Rohnert Park LRSP will complement California’s SHSP 2020-2024. The SHSP recommended
challenge areas are shown in Figure 4. This plan will focus on challenge/emphasis areas that are
determined through data analysis and stakeholder input.
Figure 4 SHSP Challenge Areas
2.2.2 Sonoma County Vision Zero
The Sonoma County Transportation Authority (SCTA) and the Department of Health Services launched a
Vision Zero plan for all of Sonoma County. The Rohnert Park LRSP aims to complement Vision Zero plan
with elements catered specifically for the City of Rohnert Park. SCTA’s goal is to produce “a project that
will focus on action-oriented strategies to reduce serious injuries and fatalities caused by traffic collisions,
and improve health, quality of life and economic vitality, particularly for low-income and disadvantaged
communities”. The vision and goals of the Rohnert Park’s LRSP document will follow similar standards.

2.2.2.1 Vision Zero
Vision Zero is a significant departure from the status quo in two major ways:
– Vision Zero recognizes that people will sometimes make mistakes, so the road system and related
policies should be designed to minimize those inevitable mistakes and reduce their likeliness to
result in severe injuries or fatalities. This means that system designers and policymakers are
expected to improve the roadway environment, policies (such as speed management), and other
related systems to lessen the severity of crashes. Roadway users are, however, still responsible for
their mistakes and should follow all applicable laws and use reasonable judgement when conducting
themselves within the public right of way.
– Vision Zero is a multidisciplinary approach, bringing together diverse and necessary stakeholders to
address this complex problem. In the past, meaningful, cross-disciplinary collaboration among local
traffic planners and engineers, policymakers, and public health professionals has not been the norm.
Vision Zero acknowledges that many factors contribute to safe mobility -- including roadway design,
speeds, behaviors, technology, and policies -- and sets clear goals to achieve the shared goal of
zero fatalities and severe injuries.
2.2.3 Safe System Approach
The Federal Highway Administration (FHWA) is using the Safe System approach to work towards their
goal of zero fatalities in vehicles. In providing a comprehensive approach to safety, the Safe
System approach is to design our vehicles and infrastructure in a manner that anticipates human error
and accommodates human tolerances with a goal of reducing fatal and serious injuries. The following
framework is intended to assist the vehicle and infrastructure communities in making decisions that will be
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 5
in alignment with Safe System principles. Implementing and selecting safe system practices and design
will incrementally improve safety over time.
FHWA defines the Safe System Approach Principles and Elements as follows:
– Safe Road Users—The safety of all road users is equitably addressed, including those who walk,
bike, drive, ride transit, or travel by other modes.
– Safe Vehicles—Vehicles are designed and regulated to minimize the frequency and severity of
collisions using safety measures that incorporate the latest technology.
– Safe Speeds—Humans are less likely to survive high-speed crashes. Reducing speeds can
accommodate human-injury tolerances in three ways: reducing impact forces, providing additional
time for drivers to stop, and improving visibility.
– Safe Roads—Designing transportation infrastructure to accommodate human mistakes and injury
tolerances can greatly reduce the severity of crashes that do occur. Examples include physically
separating people traveling at different speeds, providing dedicated times for different users to move
through a space, and alerting users to hazards and other road users.
– Post-Crash Care—People who are injured in collisions rely on emergency first responders to quickly
locate and stabilize their injuries and transport them to medical facilities. Post-crash care also
includes forensic analysis at the crash site, traffic incident management, and other activities.
Adopting a Safe System approach does not absolve users of their responsibility. Other safety practices
such as speed management strategies, driver education, enforcement, and effective emergency
response will remain essential to improving road safety. With the passing of Assembly Bill (AB) 43, new
criteria will be implemented for setting speed limits which can favor lower speed limits and keeping
existing speed limits when no significant roadway developments have occurred.
Figure 6 shows a diagram of the Safe System approach.

3. Safety Partners/Stakeholders
3.1 LRSP Stakeholder Working Group Members
Based on community connections, the City of Rohnert Park led the formation of the LRSP Stakeholder
Working Member Group. This leadership group was crucial in the development of the LRSP and helped in
capturing the safety needs, goals, and priorities, including safety countermeasures for the City of Rohnert
Park.
The following agencies were requested to participate in the LRSP Stakeholder Working Group:
– City of Rohnert Park, Public Works Department

3.2 LRSP Stakeholder Working Group Meetings
One meeting was held with the stakeholder working group. The virtual meeting was as follows:
1. April 25, 2022 – 10 a.m. to 12 p.m.
a. Discussed the LRSP overall process, working group member’s safety priorities, past 6 years
of collisions (City and Caltrans roadways), guiding principles (vision, mission, goals), and
public comments.
The meeting summary for the stakeholder working group meeting is in Appendix A: Stakeholder and
Public Input. The stakeholder working group also provided their feedback and comments on the draft
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 9
Local Road Safety Plan document before the plan was finalized. Since many of the safety
countermeasures incorporate engineering, enforcement, and emergency response strategies,
stakeholder approval is important for understanding how the plan will be implemented.
3.3 Bicycle and Pedestrian Advisory Committee
Meeting
LRSP details and progress were presented to the City’s Bicycle and Pedestrian Advisory Committee at an
in-person meeting on May 9, 2022. Feedback was solicited for the guiding principles, locations of
concern, and preferred countermeasures. The feedback received through this meeting was incorporated
into the draft LRSP.
3.4 SHSP Challenge/Emphasis Areas
Based on the collision data analysis and LRSP Stakeholder Working Group Meetings, this LRSP will
address multiple Strategic Highway Safety Plan (SHSP) Challenge Areas including:
1. Bicyclists
2. Distracted Driving
3. Aggressive Driving / Speed Management
4. Intersections
5. Pedestrians
3.5 Guiding Principles
The members of the stakeholder working group coordinated to establish the vision, mission statement,
and goals that guided the development of the document. Ideally, this document will help the City move
toward Vision Zero. The aim of Vision Zero is to eliminate all traffic fatalities and severe injuries, while
increasing safe, healthy, and equitable mobility for all. Traditionally, traffic deaths and severe injuries
have been considered as inevitable side effects of modern life. The reality is that these tragedies can be
addressed overtime by taking a proactive, preventative approach that prioritizes traffic safety as a public
health issue.

4. Analyze Safety Data
4.1 Existing Safety Efforts
The City of Rohnert Park is actively implementing various safety policies/guidelines from their General
Plan and Countywide Bicycle and Pedestrian Master Plan. There are several safety projects and
programs that are currently in progress, nearly complete, recently completed or will begin in the near
future. Some of these projects include:
– Improving pathways, removing old asphalt, and pouring concrete for 10-foot-wide multi-use
pathways along creeks and drainages
– Improving sidewalks in the public right-of-way, replacing sidewalk flags that are broken, lifting, and/or
sinking
– Replacing pedestrian ramps with modern ramps brought up to ADA standards
– Installing rectangular rapid flashing beacons (RRFBs) at specific pedestrian crossings
– Minimum green times updated to allow for bicycle users to cross at specific intersections
– School and bike safety engagement
The Rohnert Park Police Department conducts yearly presentations to local schools about
drinking and driving
– Rohnert Park Police Department and City Public Works partnership
– Every Fifteen Minutes program
An event conducted at high schools that simulates the psychological effects of student fatalities
as a result of traffic collisions
– US 101 Bike and Pedestrian Crossing study
– Pedestrian crossing enhancements (median refuge and RRFB) at Golf Course Drive and Hacienda
Way
– East Cotati Avenue, west of Camino Colegio
Paving improvements are in progress
4.1.1 HSIP, Cycle 10
Three HSIP applications were submitted by the City of Rohnert Park for Cycle 10. The applications were
for a signalized intersection improvement project, a roundabout project, and a Sonoma-Marin Area Rail
Transit (SMART) crossings enhancement project. Out of the three applications, only the signalized
intersection improvement project was funded through HSIP. The projects that were not funded through
HSIP will be locally funded. Details on these projects are provided in the sections below.
4.1.1.1 Signalized Intersection Improvement Project
The signalized intersection improvement project includes upgrades for hardware on traffic signals such as
12-inch vehicle heads, retroreflective yellow tape, countdown pedestrian signal heads, and accessible
pedestrian signals. This project also includes upgrades to detection and emergency preemption
equipment, updates to signal controllers, and installation of a battery backup system. These
countermeasures will be incorporated at forty signalized intersections throughout the City of Rohnert
Park. Figure 8 shows the locations for this project.
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 12
Figure 8 Locations of Signalized Intersection Improvement Project
4.1.1.2 Roundabout Project
The City applied for HSIP funding to convert the intersection of Southwest Boulevard and Commerce
Boulevard from all-way stop control to a roundabout. This project was not awarded HSIP funding, and
other funding sources were utilized to complete the project. Construction was completed in May 2022.
4.1.1.3 SMART Crossings Enhancement Project
Upgrades are planned for enhancing the at-grade crossings for the SMART rail at Golf Course Drive,
Rohnert Park Expressway, and Southwest Boulevard (see locations in Figure 9 below).
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 13
Figure 9 Locations of SMART Crossings in Rohnert Park
Grade crossings were evaluated for potential vehicular, bicycle, and pedestrian enhancement
recommendations. Based on the evaluation, vehicular, pedestrian, and bicycle recommendations are
provided for each grade crossing mentioned above.
4.1.2 US 101 Bike and Pedestrian Overcrossing Study
The City is assessing seven potential locations to install a bicycle and pedestrian overcrossing at US 101.
These seven locations include at Golf Course Drive, Business Park/State Farm, Industrial Park,
Hinebaugh Creek, Rohnert Park Expressway, Copeland Creek, and Cotati/Neighborhood-A. Figure 10
shows further information about each of the potential locations.

4.1.3 Central Rohnert Park Priority Development Area (PDA)
Plan
The Central Rohnert Park PDA Plan was adopted in 2016. A key component of the Central Rohnert Park
PDA Plan is an interconnected multimodal transportation network of sidewalks, bicycle, and pedestrian
paths. Some of the projects identified in this plan include:
– Slip Street construction
– State Farm Drive pavement rehabilitation
The proposed project includes pavement preventative maintenance along State Farm Drive,
Enterprise Drive, and Rohnert Park Expressway and redefining the roadways to prioritize zero-
emission users through complete streets concepts such as buffered bicycle lanes, green bike
lanes, sidewalk accessibility improvements, traffic calming, and other enhanced safety features
for bicycles and pedestrians
– Commerce Boulevard / Hunter Drive median
– Signals and other various pedestrian improvements
– State Farm Drive road-diet and rehabilitation
– Various striping projects
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 15
4.1.4 Pedestrian and Bicycle Safety Improvements Project
The Pedestrian and Bicycle Safety Improvements Project is a suite of physical improvements to improve
safety and convenience for pedestrians and bicyclists traveling within and to the Central Rohnert Park
Priority Development Area, and at other select locations of off-street pedestrian/ bicycle facilities
intersecting with streets. Improvements include but are not limited to: enhanced street crossings with
warning devices (e.g. rectangular rapid flashing beacons), pedestrian median refuge, restriping
crosswalks, traffic signal video programming modifications and signage; advanced “yield here to
pedestrians” signage & striping; parking restrictions, curb ADA upgrades; and signage geared toward
pedestrians and bicyclists on both on-street and off-street facilities.
City Staff identified 13 locations where safety improvements would be highly beneficial:
- Coleman Creek Path at Snyder Lane
- Hinebaugh Creek Path at Country Club Drive
- Hinebaugh Creek Path at State Farm Drive
- Hinebaugh Creek Path at Commerce Boulevard
- Rancho Cotate High School Path at Snyder Lane
- Copeland Creek Path at Snyder Lane
- Copeland Creek Path Connector at Camino Coronado
- Copeland Creek Path at Country Club Drive
- Copeland Creek Path at Seed Farm Drive
- Santa Alicia Drive at Arlen Drive
- Santa Alicia Drive at Avram Avenue
- Southwest Boulevard at Almond Street
- Rohnert Park Expressway at Commerce Boulevard west crosswalk (pedestrian refuge)
4.2 Collision Data
The City of Rohnert Park collision data was gathered using collisions from the City’s Crossroads collision
database. The data set contains six complete years’ worth of collisions spanning from January 1, 2015, to
December 31, 2020. Collision data on the US 101 mainline was removed, due to the lack of interaction
with the local roadways. However, the collision data at the US 101 ramps with local roads was captured in
the analysis.
During this period, a total of 1,406 collisions were reported in the City of Rohnert Park. These collisions
were classified based on location: intersection, segment, or interchange. Locations identified as an
interchange are defined as intersections where US 101 ramps meet City roadways.
The chart in Figure 11 depicts the number of collisions by collision location. The highest number of
collisions were at intersections.

4.2.1 Collisions on City Maintained Roadways
There were 1,313 collisions recorded on the City roadways between 2015 and 2020. Figure 13 shows
the breakdown of collisions by year and severity. The highest number of collisions was reported in 2018.
The number of collisions trended downward since the peak in 2018. However, there was an increase in
the number of severe injury collisions in 2019 and 2020 (8 severe injury collisions in each year) when
compared to 2018 (4 severe injury collisions). Fatalities occurred in 2016, 2017, and 2018.
Figure 13 Collisions by Year on City of Rohnert Park Roadways (2015-2020)
As shown on the collision density map (see Figure 14 below), areas with high density of collisions
include:
– Rohnert Park Expressway at Redwood Drive,
– Rohnert Park Expressway at Commerce Boulevard,
– Rohnert Park Expressway at State Farm Drive,
– Rohnert Park Expressway at Country Club Drive, and
– Golf Course Drive at Commerce Boulevard.
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 18
Figure 14 Collision Density on City Roads (2015-2020)
Rear end collisions were the most common collision type, closely followed by broadside collisions. Other
common collision types include sideswipe and hit object. Figure 15 summarizes the City collisions based
on severity and type.
Figure 15 Collision Severity and Type for City Roadways (2015-2020)
The majority of collisions were recorded as property damage only with 38% of the collisions in the past six
years recorded as injury or fatal collisions. Figure 16 displays the top five violation categories (not
including unknown/not stated) and the number of collision types per category. Improper turning was the
top violation category with sideswipe collisions as the common cause.
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 19
Figure 16 Top Five Violation Categories for Collisions on City Roadways (2015-2020)
The total number of collisions and severity ranking were assessed at the City intersection locations to aid
in the determination of the top study intersections (refer to Appendix B: Collision Data for the
breakdown of collision severity and violation type by intersection). Per the Caltrans Local Roadway Safety
Manual, it is recommended to rank locations with higher severity as higher focus.
The Highway Safety Manual (HSM) methodology of Equivalent Property Damage Only (EPDO) ranking
assigns a weight to collisions by capturing the relative severity in equivalent property damage only where
a property damage only collision is given a weight of 1. This weighting helps the locations with highest
collision severity to rank the highest.
The Local Roadway Safety Manual (LRSM) identifies a similar method for calculating EPDO, but instead
of having individual crash costs for fatal and severe injury collisions, it combines the cost of these high-
severity collisions. This is the method used to calculate the Benefit-to-Cost Ratio (BCR) in HSIP grant
applications.
To view the crash costs and associated EPDO (severity ranking) for each of these methods, see Table 1
below. Collision costs include both direct and indirect costs. Direct crash costs include ambulance
service, police and fire services, property damage, insurance, and other costs directly related to the
crashes. Indirect collision costs account for the value society would place on pain and suffering or loss of
life associated with the crash.
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 20
Table 1 Comprehensive Collision Costs and EPDO Weights
Although the past six years of data (2015-2020) was initially analyzed for the LRSP, only the past five
years of collision data was considered for countermeasure development, per HSIP grant requirements.
The collisions between 2015 and 2019 were higher than between 2016 and 2020, so the 2015 to 2019
dataset was chosen. The decrease in collisions in 2020 was likely due to the traffic pattern changes due
to the COVID 19 pandemic.
For the purposes of identifying priority locations for the LRSP, the intersections and segments with
collisions on City roadways were analyzed based off of HSM EPDO ranking, LRSM EPDO ranking, and
total collisions. The top five intersections and segments in each of these three categories were identified
as a priority. After removing duplicates between the lists, six unique City intersections, three unique City
intersections with Caltrans roadways, and seven unique City road segments were identified.
The intersection of Rohnert Park Expressway and Country Club Drive had the highest EPDO using the
HSM methodology (655) due to a fatality at that location, and the intersection of Rohnert Park
Expressway and Commerce Boulevard had highest EPDO using the LRSM methodology (355). The
intersection of Rohnert Park Expressway and Redwood Drive had the highest number of collisions (46).
Table 2 shows the top intersections, per collision analysis. Further detailed collision analysis is in
Appendix B: Collision Data.
Table 2 Top Intersections, per Collision Analysis
The segment collisions were also analyzed by EPDO and total number of collisions. Table 3 shows the
top segments, per collision analysis. Rohnert Park Expressway from State Farm Drive to Country Club
Drive had the highest EPDO rating using the HSM methodology (634) due to a fatality and Redwood
Drive from Willis Avenue to the southern City limit had the highest EPDO rating using the LRSM

4.2.2 Collisions on Caltrans Maintained Roadways
For the purpose of this plan, the only collision location analyzed under Caltrans maintained roadways was
interchanges (intersections where US 101 ramps meet with City roadways). There were 93 collisions at
interchanges between 2015 and 2020.
Figure 17 displays the top four violation categories (not including unknown/not stated) and the number of
collision types per category. Traffic signals and signs was the top violation category with the majority of
collisions cited as broadsides.

4.2.3.2 Distracted Driving
Distracted driving is categorized in collision data as inattention. Categories for inattention include cell
phones (handheld or hands-free), electronic equipment, smoking, eating, children, animals, personal
hygiene, and reading. From 2015 to 2020, there were 156 collisions with at least one party cited due to
inattention. This is approximately 11 percent of all collisions (including interchange collisions). There were
five severe injury collisions as a result of inattention (see Figure 22 for a breakdown of collision severity
with inattention as a factor).

GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 25
4.2.3.3 Aggressive Driving / Speed Management
Aggressive driving can be quantified through collision data through unsafe speed violations. There were
218 collisions on City roadways and 20 collisions on Caltrans roadways due to unsafe speed between
2015 and 2020. This is approximately 17% of all collisions on City roadways and 22% of all collisions on
Caltrans roadways. The majority of these collisions resulted in rear end collisions. There were no fatal
and six severe injury collisions as a result of unsafe speed – all occurring on City roadways.
4.2.3.4 Intersections
As mentioned in Section 4.2, there were 758 collisions at City intersections during the study period.
These account for approximately 58% of all collisions on City roadways. The top collision type was rear
end, followed by broadside. The top violation category was unsafe speed, with many of these violations
resulting in rear end collisions. Figure 23 outlines the top five violation categories and their associated
collision types for the intersection-related collisions.
Figure 23 Top Violation Categories for Intersection Collisions
4.2.3.5 Pedestrians
Pedestrian-to-vehicle collisions were approximately 3% of the total collisions and there were 43 total
pedestrian collisions on the City roadways and none on Caltrans roadways. The year 2017 had the
highest collision severity with two severe injury collisions and 2018 had the highest number of pedestrian
collisions. The number of pedestrian collisions trended downwards since 2018, with the lowest number of
pedestrian collisions in 2020. Figure 24 presents the pedestrian collision severity by year.

GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 32
6. Identify Strategies
Through coordination and feedback from the City of Rohnert Park, LRSP working group, and public
outreach; safety projects and strategies were identified for the Local Road Safety Plan. Countermeasure
development was coordinated with the City to collect feedback and identify recommended
countermeasures.
The LRSP will reference specific location engineering projects and systemic safety applications. In
addition, safety strategies and projects that address the other E’s to include Enforcement, Education,
Emergency Response, and Emerging Technologies will be discussed below.
6.1 Engineering Strategies
Per the HSIP program, engineering countermeasures are available for grant funding. Recommended
countermeasures for the priority locations were chosen per the most recent Caltrans, Local Roadway
Safety Manual (Version 1.6), April 2022, guidance from the stakeholders on preferred countermeasures,
crash characteristics, public input from the project website, and observations from Google Maps. To view
the list of available countermeasures from the LRSM, see Appendix C: Countermeasures from the
LRSM.

In general, at all major roadways, rear end collisions can be countered by consistent improvement of
signal timing (coordination, phases, red, yellow, or operation). Table 6 presents a list of possible
recommended safety countermeasures for each priority intersection, along with a subsequent Crash
Reduction Factor (CRF). The countermeasures eligible for HSIP funding have corresponding
countermeasure numbers. The countermeasure numbers can be used to find further information about
the intended use about each countermeasure in the LRSM.
One or many of the countermeasures can be selected for grant applications. It is noted that if more than
one countermeasure is applied at a location, the Combined Crash Reduction Factor (CCRF) is adjusted
multiplicatively by the following equation (CCRFi = 1- [(1-CRF1)*(1-CRF2)*(1-CRF3)] etc.).
Table 6 Recommended Countermeasures for Priority Intersections
Countermeasures were also recommended for some intersections that had high densities of collisions or
that had high numbers of bicycle or pedestrian collisions. Table 7 includes the lists of these
countermeasures.

6.1.3 Interchange Projects
There are three priority interchange locations (shared jurisdiction between Caltrans and the City) in
Rohnert Park: Rohnert Park Expressway and US 101 northbound ramps, Golf Course Drive W at US 101
southbound ramps, and Rohnert Park Expressway at US 101 southbound ramps. These locations have
many unsafe speed and traffic signals and signs violations, primarily resulting in rear end and broadside
collisions. These intersections are all signalized, and the recent signal timing improvements along
Rohnert Park Expressway and Golf Course Drive should help to mitigate the collision patterns at these
locations. Therefore, monitoring these intersections and the effect of the improvements is recommended.
6.1.4 Identified Challenge/Emphasis Areas
Per the SHSP, the identified challenge/emphasis areas for the LRSP were as follows:
1. Bicycling – Bicycling safety countermeasures/projects were recommended at multiple
locations.
2. Distracted Driving – Prevention of distracted roadway usage is addressed though education
and enforcement component of the non-engineering strategies. These strategies can be
communicated through the police department, social media channels, and through the schools.
3. Aggressive Driving / Speed Management – Aggressive driving can include higher speeds and
improper turning and passing. Engineering strategies were identified for intersections and
segments at locations where these issues were identified. Non-engineering strategies to prevent
aggressive driving includes enforcement in selective areas with a speed management education
campaign.
4. Intersections – Projects were identified for the top intersections with collision severity and
frequency.
5. Pedestrians – Providing pedestrian accommodations to include crossing enhancements. Other
locations for pedestrian improvements are identified in the engineering strategies. Non-
engineering strategies to improve pedestrian safety will be discussed in a later section of the
document.
6.1.5 Systemic Safety Countermeasures
When selecting countermeasures, just focusing on locations with a current collision issue is a reactive
approach to roadway safety planning. A reactive approach targets recent hot-spots and specific problems
that are associated with these locations; as a result of this approach, locations with low traffic volumes but
with similar safety issues as hot spot locations are not addressed. In order to mitigate collisions in a both

a reactive and proactive approach, Caltrans’ Local Roadway Safety Manual suggests agencies utilize a
comprehensive approach that includes systemic and hot spot location improvements in developing a
safety plan.
While analyzing crash characteristics at the priority locations in the City, patterns in crashes were also
identified. Potential countermeasures that can be applied systemically throughout various locations in the
City are presented in Table 11 below.
Table 11 Recommended Systemic Countermeasures
6.1.5.1 Install/Upgrade Signs with New Fluorescent Sheeting
The countermeasure to install/upgrade street signs with new fluorescent sheeting (R22) has the following
guidance, per the LRSM:
“This CM only applies to crashes occurring within the influence area of the new/upgraded signs.
This CM is not intended for maintenance upgrades of street-name, parking, guide, or any other
signs without a primary focus on roadway safety. This CM is not eligible unless it is done as
part of a larger sign audit project, including the study of: 1) the existing signs' locations, sizes
and information per MUTCD standards, 2) missing signs per MUTCD standards, and 3) sign
retroreflectivity. The overall sign audit scope (or a special exception from the HSIP program
manager) must be documented in the Narrative Questions in the application. Based on the scope
of the project/audit, it may be appropriate to combine other CMs in the B/C calculation.”
When requested, Caltrans provided further detail on what can be funded through the countermeasure
(see text below).
“This sign audit and the associated studies are fundable through the HSIP. It will not be a
separate application but will be included in the application to install/upgrade signs with new
fluorescent sheeting as its PE cost.
For an application, the HSIP amount for PE normally should not exceed 25% of the HSIP amount
for Construction Items. But if it does go over 25% due to the sign audit and studies, it should be
explained in the application.”

6.1.6 Active Transportation
Rohnert Park has an active walking and biking community, with many multimodal improvements already
on the roadways or in planning and design phases. In evaluating future transportation projects, it is
important to look for opportunities to incorporate facilities and safety improvements for bicycle,
pedestrians, and transit, including evaluating protected bikeways and separated pedestrian pathways.
This will help to provide a safe alternative to driving and reduce greenhouse gases while increasing the
health and vitality of the community.
6.2 Non-Engineering Strategies
A comprehensive approach to selecting countermeasures recognizes that not all safety issues can be
addressed through infrastructure improvement. The comprehensive approach to safety involves the 5 E’s
of traffic safety. Besides engineering safety countermeasures, it is important to recommend safety
countermeasures to coincide with the other safety E’s. Table 12 shows some of the identified non-
engineering strategies.
Table 12 Non-Engineering Strategies
6.3 Projects Suggested Through Public Input
The interactive map tool on the public website for the plan gathered many suggestions from community
members for areas of improvement. These suggestions were summarized and are shown in Table 13

7. Prioritize and Incorporate Strategies
7.1 Funding Sources
The City of Rohnert Park can look for opportunities to incorporate safety enhancements with the City’s
Capital Improvement Program. However, it is noted that funding is limited and typically used for roadway
maintenance. Additional funding opportunities can come through grant funding to include HSIP, ATP,
OBAG, and CMAQ.
The primary source of potential funding for projects recommended in this plan is HSIP funding. Each
cycle has available project funding for Benefit to Cost Ratio (BCR) and funding set-aside projects. BCR
projects use expected benefit and estimated cost to determine eligibility and likelihood for receiving
funding. The expected benefit is determined using the crash history and the predicted collision reduction
from the recommended countermeasures. On the other hand, funding set-aside projects do not require a
collision history. The set-aside countermeasures available to agencies for HSIP Cycle 11 include
guardrail upgrades, pedestrian crossing enhancements, installing edgelines, bike safety improvements,
and tribes. These set-aside countermeasures can be applied at multiple locations (systemically) as long
as the requested funding is still within the maximum funding amount available per agency.
ATP funding for engineering projects is primarily for installing or improving non-mobilized transportation
infrastructure. Projects are more likely to receive this type of funding if it helps to increase the number of
walkers and bikers in a disadvantaged community, or improves the safety of children, specifically at
school zones. Ultimately, the goal of this type of funding is to increase the use of active transportation.
For funding for the non-engineering strategies, the California Office of Traffic Safety has grant
opportunities the City’s Police Department can pursue for additional enforcement and traffic safety
education. Some campaigns highlighted in their website include impaired driving, distracted driving,
pedestrian and bicycle safety, and speeding. The website provides educational materials, safety tips,
facts, and resources to use in educating the public on traffic safety.
7.2 Prioritized Projects
In evaluating how to implement safety projects, preliminary benefit-to-cost ratios (BCRs) for priority
intersection and segment projects were calculated using the HSIP Cycle 11 Analyzer. Tables 14 and 15
contain lists of the proposed intersection and segment projects and their corresponding BCRs. These
tables also show potential funding opportunities. It should be noted that some of the recommended
countermeasures are not current HSIP countermeasures. However, these improvements can typically be
included in an HSIP project provided the cost does not exceed 20% of the total project cost.
In addition, the awarded projects through the BCR application for HSIP Cycle 10 started at a BCR of 12.
Although the minimum for the grant application was a BCR of 3.5, the projects submitted were very
competitive. Some of this was due to funding shortfalls with COVID lockdowns and the HSIP grant
application deadline extension which allowed more agencies to submit. Therefore, the maximum project
cost is also included for a BCR of 10.
Costs used to estimate the preliminary BCRs are planning-level construction costs with a 30%
contingency.

8. Evaluation Process
To evaluate the success of this plan, yearly collision analysis, along with requests for public feedback,
can take place and be compared to the established goals.
Goal 1
Maintain existing Crossroads collision database and standardized reporting practices.
Measure of Success: Crossroads collision database has an increase in accurately reported collision
information including coordinates, collision types, violation categories, etc.
Goal 2
Revaluate collision trends and associated countermeasures in the LRSP every 5 years and engage
community, stakeholders, and City management.
Measure of Success: Collisions are reviewed every 5 years and LRSP is updated accordingly.
Goal 3
Develop an implementation priority for identified countermeasures. Implement countermeasures utilizing
strategies across all traffic safety E’s; engineering, emerging technologies, enforcement, education, and
emergency response.
Measure of Success: Priority for implementing countermeasures is planned. Implemented
countermeasures not only incorporate engineering strategies, but also other disciplines such as emerging
technologies, enforcement, education, and emergency response.
Goal 4
Reduce rear end collisions with intersection operational improvements.
Measure of Success: Collisions resulting in rear ends reduce after improvements to intersection
operations are completed. This could be quantified by a 5% decrease in rear end collisions after two
years.
Goal 5
Implement speed management strategies and increase enforcement presence.
Measure of Success: Road users increasingly obey traffic laws, specifically related to speed. Strategies
targeted towards managing speed are prioritized with a reduction in speed related collisions.
Goal 6
Reduce pedestrian and bicycle collisions with improved accommodations.
Measure of Success: Pedestrian and bicycle collisions trend downward in a 5-year period.
GHD | City of Rohnert Park | June 2022 | Local Road Safety Plan 46
Goal 7
Improve safety and accessibility for vulnerable road users.
Measure of Success: The number of residents choosing active transportation more often noticeably
increases. This can be captured through a public survey.
Goal 8
Improve safety around schools with a connected multimodal system, enhanced crossings, enforcement of
school zones, education campaigns about school drop off/pick up, bicycle and pedestrian safety, and
driver awareness.
Measure of Success: Residents will feel more comfortable choosing multimodal transportation to travel
to and from school destinations and express an increased feeling of safety in these areas. This can be
captured through a public survey administered by the school districts.

9. Next Steps
The Draft Local Road Safety Plan will be presented to City Council for comments on July 26, 2022. This
will be an informational meeting to gather direction from City Council before the Final Local Road Safety
Plan is presented for adoption on August 9, 2022. This safety plan will be a living document and will guide
the City’s roadway safety needs for the next five years. It will be updated as needed and the goals will be
monitored.

Interactive Map CommentsID Created on Type CommentUp VotesDown VotesLatitude Longitude Location Response to Comment1 6/21/2021 16:56Pedestrian Safety CommentThe pedestrian crossing here needs some visibility enhancement. Because it's on a tight horizontal curve and there is a fair amount of speeding on Golf Course, I have witnessed and been victim of several near misses. This crossing is especially precarious at night. I think this could be a good candidate for additional illumination and possibly an RRFB. Also, some pedestrian crossing yield triangles wouldn't hurt.1 0 38.365736 -122.691616Golf Course Drive / Halcyon PlaceThank you for sharing your suggestion.

It was considered in the development of the Local Road Safety Plan (LRSP). 12 6/21/2021 20:09Vehicle Safety CommentThere is a very unnatural flow of southbound traffic in this stretch. The lane with most of the traffic turns into a left turn lane, while the right lane is directed to merge into it. So, you've got cards suddenly moving right to avoid the turn lane, with others merging towards the left. I could see this causing accidents.0 1 38.361205 -122.712308Southbound Commerce Boulevard, south of US 101 NB RampsThank you for sharing your observation.

This is a residential area with children walking to and from school. There is also a very popular walking path to this park here. We need speed humps and fast. It will stop people that down live down this street from using it as a quick way to get past the lights on golf course.3 0 38.367355 -122.692866 Hudis StreetThank you for sharing your concern.

It was considered in the development of the Local Road Safety Plan (LRSP). 17 6/22/2021 8:13Vehicle Safety CommentInstall a roundabout to improve visibility to oncoming traffic, improve pedestrian safety in crossing SW Blvd,, and to slow speed on this section of SW Blvd. SW Blvd has become a raceway with speeds commonly close to 50 mph by some motorists and cyclists. Am a 40+ year resident in this neighborhood. Roundabout slows speed, there is room for one at this intersection, and is cheaper in long run than a traffic signal.0 1 38.339584 -122.687832Southwest Boulevard / Avenida CalaThank you for sharing your suggestion. It was considered in the development of the Local Road Safety Plan (LRSP). 18 6/22/2021 8:17Vehicle Safety CommentSpeed bumps needed on this section of Avenida Cala to slow speed of cars. With in-class education resuming at the Ranch, this is a "short-cut" street used by parents/students to avoid intersections governed by traffic signals and wait times. Camino Coronado has street bumps for same reason, for cars coming off Country Club Dr. Camino Corto is also a a good candidate as cars speed from stop sign to the Camino Corto/Snyder intersection.2 1 38.340259 -122.687955Avenida Cala, north of Southwest BoulevardThank you for sharing your suggestion. It was considered in the development of the Local Road Safety Plan (LRSP). 19 6/22/2021 8:24Bicycle Safety CommentIs the north side of this road going to be striped with a bike lane? When reaching the signal, many cars still try to create a 3rd lane, a right-turn lane, onto Seed Farm Drive, even tho the bike lane markings have been removed. If no bike lane, is it possible to safely create a right hand turn lane to alleviate backup and to make clear there is either 1 lane or 2.1 0 38.341294 -122.696632Westbound approach to Southwest Boulevard / Seed Farm DriveThank you for sharing your observation.

Add to that the people that are trying to drop off their kids at school, the distracted drivers, the annual Sonoma State renters, the sun in your eyes when headed West, no posted speed limits or traffic enforcement, and you get real sketchy stretch of road.0 0 38.351467 -122.694068Emily Avenue near Country Club DriveThank you for sharing your concern.

I have crossed this intersection on foot nearly every day for 18 years, and I can say that the number of times cars have stopped for a pedestrian crossing has only been a handful in all that time. It is also in close proximity to two schools, and there tends to be a lot of children crossing the street in this location as well.1 0 38.339555 -122.687942Southwest Boulevard / Avenida CalaThank you for sharing your suggestion.

Project Survey
Are there additional safety concerns that you think the City should be considering? If so,
describe below.
Response
Plan streetwork better...for a while recently we only had one north-south street free.
Potholes are a BIG issue. Also bushes/trees need to be trimmed where they grow over and get in the
way of street signs.
Positioning of light stands and other sidewalk signage frequently pushes pedestrians into the street and
blocks driver and pedestrian views of each other.
The city doesn’t do enough to trim trees, shrubs at street corners, all over the city. Stop signs, street
lights and speed limit signs are obscured. Not only is this an issue surrounding this city but speeding is
as well.
Enforcement supports the engineering, but in the long run, the engineering solutions are cheapest and
support 24/7 safety
I could pick only one issue, but really there should be two: speeding and texting. What do you mean by
most affective? Did you mean effective. We could use more visibility of our enforcement officers.
Speeding and running stop signs has been horrid the past 16 months. Step up enforcement, raise the
fines. Anyone who talks back, arrest them.
I have been walking with a stroller AND driving near the Jr High at the end of the day and have nearly
been hit by boys riding there bikes on the sidewalk (which I don't mind, except they ride two and three
abreast and don't yield to pedestrians. These same boys and done wheelies on the sidewalks AND in
the bike lane and nearly hit me in my 3/4 to pickup. Perhaps have an officer cleverly placed so they can
see the kids and the kids can't see them....for all I know, these boys may be in High School now. But it
has been dangerous.
...again
YES! -- now that they have widened Expressway all the way to Pet-Hill-Road? Every intersection has a
stop-light - as they should to manage speeders - BUT, why did they NOT put one in at the 3-way of
Expressway/Jasmine Circle/&/Oak-View-Circle?
.
This is just NUTZ that they did NOT put one in.
.
So - now you have your night-time balls-to the walls drivers heading east on expressway from Snyder g-
u-n-n-i-n-g it ...sigh -vs- managing them dang speeders with a light at that three way - Now the addition
of a traffic light at the three way of "Expressway/Jasmine Circle/&/Oak-View-Circle" IS a must to be
added to the City of R.P. 'Roadway Safety Plan'!
Speeding. Many people speed on the roadways. So many in residential areas.
So much speeding throughout the city! I live on Southwest Blvd between Camino Colegio and Country
Club,m which has become a drag strip straightaway in recent years and rarely, if ever do I see any patrol
cars parked in Camino Vista Park. Maybe some strategically placed license plate cameras are called for
in this town. Maybe a good muffler shop as well!!
At intersections with a yellow flashing left turn signal, there should be a 4 light fixture instead of a 3 light,
so one can call a green left turn signal if opposing traffic is busy. It appears that only in A section these 3
light fixtures are used while in other sections there are 4 light fixtures. This shows where the City's
priorities are, not with minority neighborhoods obviously.
safer bike trails. East West trail connector.
Page 1 of 3
On Golf Course Drive in the front of the golf course there is a merge and people acclerate their speed to
pass the other aggressively. It is ridiculous how some people think they own the road. I almost want to
add the lack of education but it is also a lack of decency towards others. There needs to be
enforcement before another fatality.
Seems like nobody through our town likes to make a stop at stop sign intersections.
ALL crosswalks should be zebra striped and those near schools and bus stops equipt w/flashing lights,
cameras need to be in parks and trails, and ALL signals need reflective outlines.
All too often tree or foliage block the view of stop signs.
Some speed limit signs are obscured by trees. Obstructions to views of road signs should be removed.
residents in new housing on north side of expressway are using the walking path along hinebaugh
creek. There is no crossing protection for them on Snyder and I am one of the very few that will yield to
allow the to cross snyder. Ther needs to be cross walk and signage for their protection.
The streetlights seem to be brighter in Cotati than in Rohnert Park. I am concerned about pedestrian
safety at night throughout the City, but in particular on busy roads.
Potholes and conditions of the roads need addressing.
Expressway and Snyder. If Police would just park here, I guarantee they would make a lot of money for
the city. It is a raceway here. I'm afraid to cross the street!
There are seldom any patrol cars driving around. If there is a presence, there would be more people
falling driving laws. Stop signs need to be well marked, some signs are blocked and the white that states
stops are very faded.
There are multiple intersections that need attention...especially in the area of Redwood/Golf
Course...also the nonsense that is the area of Krispy Kreme/In&Out Burger
Impaired drivers coming from the casino through town on Golf Course Dr. to avoid the freeway. Blind
corners due to vegetation.
More police officers dedicated to traffic enforcement; more intersections controlled by stop signs, signals
or roundabouts (yes, a pain to stop, but they SLOW traffic); more traffic signs that warn of curves in the
roadway; as roads are repaved or improved around town, look for ways to better stripe the roads,
straighten out weird curves, would rather see roads narrowed to one lane than have merge arrows as
drivers simply speed up instead of merging.
Increased enforcement once fall term starts for the schools. It was great 3-4 years ago and then slowly
tapered off. My child attended Monte Vista and there were consistently issues with drivers making illegal
u-turns, dangerous maneuvers out of parking spaces, unsafe pedestrian movements, and drivers
passing lines of cars on the wrong side of the road. If all/most patrol officers were dedicated to schools
in the 20 minutes prior to the start of school, families would be safer and the efforts of your officers
would be front and center.
Paved roads are important. Visabilty at night with lighted signs. RP Expressway is a problem with
speeding at night. As a resident at Oak View Apartments, this is an issue. Please install more Speed
Monitors in that area on both sides of the street.

Oh I have a couple. 1. Turning left (south) from RP Expressway on to Commerce Blvd, there is ONE
turn lane and often I see people using the lane next to the turn lane to turn left as well, because there
are 2 lanes on Commerce. I have seen a collision as a result of this. There needs to be better signage
above the light I think. 2. Visibility / Speeding on that stretch of Commerce Blvd. between RP
Expressway and Hunter Drive is Awful and there are so many ins & outs. I'm not sure how to fix this but I
have been in TWO collisions, neither of which were my fault - the first was someone turning into the
Safeway parking lot while I was going straight, the second was someone coming from the Grocery
Outlet parking lot who struck my vehicle and then fled the scene. That one totaled my car and I'm still
really upset about it. I avoid this stretch of road now as much as possible.
Posted speed limits and enforcement, especially the residential sections.
There's considerable speeding on Rohnert Park Expressway above Snyder and a fair amount of
speeding on Snyder as well. I've not often seen a police car in these areas.
Many STOP sign are hidden by growing tree. Even though letter STOP are painted on the street, many
out of city driver cannot see these painted sign until they are too close to the intersection. I wish these
branches hiding the STOP sign should be trimmed.
Bike lanes need to be a priority. It's far too dangerous to ride a bike in some areas
Daniel Drive has become a speedway for residents in D section who bypass Country Club Dr., often at
speeds above 35 mph. It's a long stretch of roadway and I highly recommend that a speed bump be
placed somewhere in mid-block before someone is seriously injured!
more cross walk lights for pedestrians--- also more benches on main streets for the elderly--- between
bus stops maybe---and also BIG THING FOR DEPRESSION AND SUICIDE---GET BLUE LIGHTS OR
FILTERS FOR THE STREET LIGHTS----- STUDIES SHOW LESS SUICIDES WHERE CITIES HAVE
BLUE LIGHTS IN ALL STREET LIGHTS. we have a lot of train track suicides in this town
Cars are running red lights on a regular basis.
Safe access to and from the SMART bike trail, for cyclists.
Upkeep and maintainance in bike lanes on roads, to keep them clear of debris. In places cars parked in
bike lanes are a hazard, and people leaving trash cans etc. in bike lanes.

There needs to be a crosswalk at hinebaugh
creek and snyder lane with illuminated singal.
Every day during school there are kids
waiting on their bikes who cross over snyder
from k section to continue down hinebaugh
creek to evergreen school.
Thank you for sharing your feedback. The
City is evaluating this crossing location.

There is a ton of information in this draft.
Many changes involve things that I am not
clear exactly what they are. I think the public
needs for a presenter with each project
separately with a picture of what it would look
like highlighting with the changes are so we
can actually know what this plan is going to
do.
The plan identifies traffic safety needs and
possible improvements the City could
implement to improve safety.
