SUBJECT: POLICY RECOMMENDATIONS & IMPLEMENTATION PLAN FOR THE CITYWIDE
SPEED REDUCTION PROGRAM, CITY OF RIVERSIDE
Dear Mr. Nitollama:
INTRODUCTION
RK ENGINEERING GROUP, INC. (RK) is pleased to submit this Implementation Plan and Policy Recommendations for the City of Riverside Speed Reduction Program. The purpose of the Citywide Speed Reduction Program was to evaluate the posted speed limits for 319 roadway segments and provide an engineering and traffic survey (E&TS) per the requirements of the California Vehicle Code (CVC) and the California Manual on Uniform Traffic Control Devices (CA MUTCD). This work has been funded through the FY 2023 Safe Streets for All (SS4A) Supplemental Planning Grant, which supports local initiatives aimed at improving roadway safety through data-driven planning and the Safe System Approach. The overarching intent of the program has been to improve safety for all roadway users by identifying opportunities to reduce vehicle speeds where appropriate.
The purpose of this report is to present policy recommendations that serve as a guide for the prioritization of roadway segments that will require the implementation of speed management treatments as part of the Citywide Speed Reduction Program. These recommendations are intended to promote consistency by outlining steps for identifying, evaluating, and implementing speed management treatments. This includes using documented speed data to select candidate corridors, applying the appropriate criteria to prioritize roadway segments, and coordinating with capital improvement planning to integrate treatments into resurfacing, restriping, or reconstruction projects.
BACKGROUND
Managing vehicle speeds is a critical component of roadway safety, particularly on corridors with mixed land uses and multimodal activity. Excessive vehicle speeds increase the likelihood and severity of collisions and reduce safety for pedestrians and bicyclists.
RK21228.2 // 0619-2025-01 2
The Citywide Speed Reduction Program establishes a technical basis for identifying appropriate speed limits and this report builds upon that effort by providing guidance and implementation recommendations to support the systematic implementation of speed management treatments.
POLICY RECOMMENDATIONS
Based on engineering judgement and city coordination, it is recommended that roadway segments are prioritized for the implementation of speed management treatments based on varying criteria.
Priority Criteria
Roadway segments should be evaluated and prioritized using the following criteria, with excessive speeding serving as the primary basis:
1. Excessive Speeding
The 85th percentile speed exceeds the recommended speed limit by at least eight (8) miles per hour (mph) or more, based on the Citywide Speed Limit Reduction Program. The roadway segments that meet the excessive speeding criteria are listed in Table A.
2. Safety Corridor Designation
Per the MUTCD, Safety Corridors are defined as “a roadway segment within an overall roadway network where the highest number of serious injury and fatality crashes occur.” The MUTCD further details that the Safety Corridors must not exceed one-fifth of the overall roadway network and that one or more crash weighting factors from MUTCD Table 2B-105(CA) are applied to prioritize roadway segments.
Pursuant to these guidelines, Safety Corridors were designated as part of the Citywide Speed Limit Reduction Program and are listed in Table B and Exhibits A-1, A-2, and A-3.
3. Roadway Classification
Arterial and collector roadways where excessive speeds increase safety risks due to:
o Traffic volumes
o Corridor length and lane geometry
o Transitions between higher speed and lower speed segments
4. Presence of Vulnerable Road Users
Roadway segments adjacent to land uses that generate pedestrian, bicycle, or transit activity, including schools, parks, transit stops, senior centers, and neighborhood commercial areas.
5. Lack of Active Transportation Infrastructure
Roadway segments that lack a presence of sidewalks or bike lanes forcing pedestrians or bicyclists to travel within the same lane as vehicles increasing their vulnerability.
RK21228.2 // 0619-2025-01 3
Priority Tiers
To support consistent and transparent implementation of speed management treatments, roadway segments shall be categorized into priority tiers based on the criteria listed above. These tiers are intended to guide sequencing on implementation.
Tier 1 – High Priority
Tier 1 roadway segments include roadway segments that meet all of the following criteria:
Excessive speeding by 10 mph or more over the recommended speed limit, as highlighted in Table A; and
Designated Safety Corridor; and
Classification as a major arterial roadway; and
Presence of Vulnerable Users; and
Lack of Active Transportation Infrastructure.
Tier 1 roadway segments represent the highest priority for implementation of speed management treatments due to the combination of speed related risk, corridor importance, and roadway function.
Tier 2 – Priority
Tier 2 roadway segments include locations that have excessive speeding and meet at least one of the following criteria:
Excessive speeding by 8 mph or more over the recommended speed limit; and Designated Safety Corridor; or
Classification as a major arterial roadway; or
Presence of Vulnerable Users; or
Lack of Active Transportation Infrastructure.
Tier 2 roadway segments warrant consideration for implementation based on available funding, project timing, and engineering judgment.
Tier 3 – All Other Segments
Tier 3 roadway segments include all remaining locations that do not meet Tier 1 or Tier 2 criteria.
These roadway segments may be considered for speed management treatments on an opportunistic basis, including through future studies, community requests supported by data, or as part of broader corridor or neighborhood improvement efforts.
RK21228.2 // 0619-2025-01 4
IMPLEMENTATION PLAN
The following implementation plan outlines recommended speed management treatments for prioritized roadway segments identified through the Citywide Speed Reduction Program. These treatments are intended to reinforce posted speed limits, improve driver awareness, and encourage speed compliance using easily deployable measures.
Objective 1: Pavement markings are recommended on prioritized roadway segments to reinforce regulatory signage and communicate speed expectations at key transition points.
Action Plan 1.1: Pavement markings with appropriate numerals may be used to supplement speed limit signs a points of change from one speed limit to another or at the downstream, end of the section to which a particular speed limit applies.
Action Plan 1.2: Pavement markings shall be consistent with applicable CA MUTCD standards and guidance.
Objective 2: Vehicle Speed Feedback signs (W13-20) or plaques (W13-20aP) display the speed of an approaching vehicle to provide warning to drivers of their speed in relation to the speed limit. Vehicle Speed Feedback signs or plaques are recommended on prioritized roadway segments to provide real-time feedback to motorists and encourage voluntary speed compliance.
Action Plan 2.1: Locations should be selected based on documented speed data, roadway context, and engineering judgment.
Action Plan 2.2: Vehicle Speed Feedback signs (W13-20) or plaques (W13-20aP) shall be installed per CA MUTCD standards and guidance.
Objective 3: Pursuant to California Assembly Bill 382 (AB 382) local authorities are authorized to implement 20 mph speed limits in school zones to enhance safety for students and other vulnerable road users.
Action Plan 3.1: Prior to January 1, 2031, the City of Riverside may, by ordinance or resolution, determine and declare a prima facie speed limit of 20 mph in school zones. School zone locations shall be evaluated to confirm eligibility and ensure that signage placement, limits, and operational conditions are consistent with state law and engineering judgment.
Action Plan 3.2: After January 1, 2031, the prima facie speed limit will be 20 mph in all school zones. Replace speed limit signs in accordance with the new laws.
RK21228.2 // 0619-2025-01 5
Objective 4: Mobile speed radar trailers are recommended on roadway segments to provide temporary, highly visible speed feedback to motorists and increase overall awareness of operating speeds.
Action Plan 4.1: Implement mobile speed radar trailers on a rotating basis to address multiple locations and response to community concerns.
Action Plan 4.2: Locations and durations should be determined based on documented speed data, roadway characteristics, and operational considerations, allowing for flexible and rapid implementation.
FUNDING AND FUTURE CONSIDERATIONS
The successful implementation of the recommended speed management treatments will depend on strategic coordination with existing and planned transportation projects. To maximize efficiency and minimize costs, it is recommended that treatments identified through this implementation plan be incorporated, where feasible, into the following:
Roadway resurfacing, restriping, or reconstruction projects Corridor improvement projects
Grant funded projects
Conditions of approval for land development projects
Other planned transportation improvements where scope and timing allow This approach supports efficient implementation while minimizing the need for standalone projects.
Implementation of the recommended treatments may be supported through local capital programs and external funding opportunities. The prioritization criteria and documented speed data established through the Citywide Speed Reduction Program may be used to support future project development and funding applications. These policy recommendations and implementation guidance may be refined over time to reflect updated data, performance outcomes, and evolving best practices in speed management.
RK21228.2 // 0619-2025-01 6
CONCLUSION
This memorandum provides policy recommendations and an implementation plan to support the Citywide Speed Reduction Program. By prioritizing roadway segments based on documented excessive speeding and integrating speed management treatments into planned transportation projects, the City can systematically address speed-related safety concerns in a consistent and effective manner.
