WORKS/CITY ENGINEER
DATE: AUGUST 27, 2024
SUBJECT: ADOPTION OF RESOLUTIONS CERTIFYING AN UPDATE TO THE CITY’S LOCAL ROAD SAFETY PLAN AND AUTHORIZING THE
SUBMITAL OF APPLICATIONS FOR HIGHWAY SAFETY
IMPROVEMENT PROGRAM FUNDS TO IMPLEMENT VARIOUS
TRAFFIC SAFETY PROJECTS
EXECUTIVE SUMMARY
During Fiscal Year 2023-2024, the City Council requested an analysis of traffic conditions throughout the City, focusing on safety and collision history at various intersections in Downey. In 2022, the City Council adopted the Local Road Safety Plan (LRSP), which focuses on collision history, identifying accident trends, and prioritizing projects based on severity of incidents and developing solutions to mitigate and reduce the likelihood of collisions from occurring. Staff met with its traffic engineering consultant and original author of the LRSP, Willdan Engineering (Willdan), and requested an update to the plan.
The resulting update to the LRSP provides a new list of prioritized intersections and corridors requiring safety improvements based on collision data collected between 2020 and 2023. This report provides a summary of actions that staff has taken since the original LRSP was adopted, as well as plans that are being developed to address the prioritized areas outlined in the update. Examples of other traffic safety projects that are currently underway that fall outside of those identified in the LRSP are discussed, as well how the LRSP data is used to apply for new grant funding under Cycle 12 of the Highway Safety Improvement Program (HSIP).
RECOMMENDATION
That the City Council:
1. Discuss the update to the City’s Local Road Safety Plan;
2. Adopt Resolution No. 24-8265, approving the City’s Updated Local Road Safety Plan; and,
3. Adopt Resolution No. 24-8266, approving the submittal of Highway Safety Improvement Program (HSIP) funding applications.

2 BACKGROUND
At its November 14, 2023 meeting, the City Council requested that staff look at traffic safety throughout the City and provide a report at a future meeting. In 2022, staff prepared the Local Road Safety Plan (LRSP), which provides a framework for cities to prioritize roadway safety improvements based on an evaluation of locations with high collision rates. The City Council originally adopted the LRSP at its September 27, 2022 meeting (LRSP 2022). The completion of this plan was a necessary element required by Caltrans prior to applying for any State or Federal grant funding related to traffic safety projects through the Highway Safety Improvement Program (HSIP) – a common source of traffic safety funding for municipalities. The original plan focused on traffic collision data collected between 2015 and 2020.
As part of LRSP 2022, Willdan identified five traffic safety projects that would be competitive under the HSIP Cycle 11 Call for Projects. These projects included:
1) upgrading traffic signal hardware on Firestone Boulevard; 2) pedestrian crosswalk upgrades with high visibility features; 3) bike lane installation on Old River School Road, Brookshire Avenue, and Foster Road;
4) traffic signal upgrades at 11 intersections Citywide; and 5) installing raised medians on Florence Avenue.
Staff did apply for grant funding for these projects as part of Cycle 11 and was successful in getting funding for the pedestrian crosswalk upgrades at two locations on Gardendale Street (Saint Mathias Academy and Hoover Avenue) and on Downey Avenue (Our Load of Perpetual Help School). The funding secured from Cycle 11 is being used for the design construction for these improvements, which will begin in September 2024.
The HSIP funding program is highly competitive, and staff continually looks for other funding sources to address traffic safety projects, such as funding from Metro for bike lane improvements and State and County local return funds that can be used for traffic signal upgrades and raised medians. As an example, staff has developed CIP projects that focus on three of the intersections along Firestone Boulevard. A combination of local return funds (Measure R and Proposition C) and a grant from Metro will fund intersection improvements along Firestone Boulevard at Lakewood Boulevard, Downey Avenue, and Rives Avenue. The design of Firestone Boulevard and Lakewood Boulevard intersection improvements are near completion, and the project will go out to bid for construction in Fall 2024. This intersection is prioritized in LRSP 2024 based on having the highest weighted collision score in the City. As a result, staff anticipates completing this project by the summer of 2025.

3 In response to the City Council’s request from its November 14, 2023 meeting to look at traffic safety Citywide, staff asked Willdan to update the plan (LRSP 2024) to focus on traffic collision data collected between 2020 and 2023 and identify any new collision trends or potential traffic safety projects (see Attachment A).
ANALYSIS
In reviewing the collision data as part of LRSP 2024 for the 4-year period between 2020 and 2023, a prioritization method was established that first identified the locations with the highest number of incidents and then drilled down deeper to score these locations based on the severity of any collisions (ranging from property damage to fatality) and type of incident (e.g., rear-end or broadside). The more severe the collision, the higher the weighted score that is given to that particular incident. The type of collision and cause is helpful in determining a list of potential mitigations that can be used to reduce the likelihood of the collision occurring in the future. A heatmap was created to visually summarize the collision history across the City between 2020 and 2023 (Attachment B).
Intersection Analysis and Recommended Projects
Using the weighted crash scoring, Willdan was able to develop a list of the following ten intersections as the highest priority for traffic safety mitigation:

5 The LRSP goes into detail on the existing conditions and recommended improvements for each of these intersection projects (see pages 37 through 46 of the LRSP). A summary of what actions have been taken by staff already to address some of these intersection projects includes the following:
• Firestone Boulevard at Lakewood Boulevard (to be completed by the summer of 2025) and Firestone Boulevard at Downey Avenue and Rives Avenue intersection improvements. These two intersection improvements are currently in design. Staff will address the Downey Avenue intersection improvements as part of the Downey Avenue Pavement Rehabilitation Project to be completed by the summer of 2025.
The Rives Avenue intersection improvements would be addressed as a separate project to be completed by the end of 2025.
• Fairford Avenue at Cecilia Street is a shared intersection with the City of Norwalk.
Staff took the lead in completing an analysis of traffic safety issues related to this intersection. Since the majority of the project falls under the jurisdiction of Norwalk, staff shared its findings with their staff, and they recently completed their own

6 analysis and the Norwalk City Council approved a street humps project that will be completed by the summer of 2025. The City will be paying its prorated share of between 40 and 50 percent of the project costs, but Norwalk will be taking the lead on construction.
Corridor Analysis and Recommended Projects
Similarly, corridors in the City were also analyzed for frequency, severity, and type of collisions and were ranked according to weighted value per mile, as shown in the following table:
Looking at the types of collisions and their primary causes, Willdan prepared a list of recommended improvements, as shown in the following table:

7 The LRSP goes into detail on the existing conditions and recommended improvements for each of these corridor projects (see pages 47 through 56 of the LRSP). A summary of what actions have been taken by staff already to address some of these corridor projects includes the following:
• Firestone Boulevard corridor improvements are taking place at three of the prioritized intersections at Lakewood Boulevard, Downey Avenue, and Rives Avenue.
Additionally, the entire corridor is being analyzed for improvements and will be part of an HSIP grant funding application submitted by September 9, 2024 to address traffic signal upgrades at the remaining 12 intersections along this corridor. The project will also look at other improvements that could make the area safer for pedestrians.
• Hall Road is being addressed as part of annual miscellaneous projects that will make sidewalk, curb ramp, median, pavement marking, and stop sign improvements along the corridor between Lakewood Boulevard and Woodruff Avenue. In addition to this

8 work, some median improvements are also being implemented as part development in the area. Overall, improvements along this corridor will start taking place in the spring as part of the City’s Annual Miscellaneous Concrete project.
Many of the other corridor projects on this list have some improvements being addressed as part of future CIP projects in the next two to three years. These include:
Intersection Improvement Projects at Paramount Boulevard and Lakewood Boulevard;
Florence Avenue: Traffic Signal and Curb Ramp Improvements at Downey Avenue and Brookshire Avenue; Intersection Improvement Project at Lakewood Boulevard;
Lakewood Boulevard: Intersection Improvements at Firestone Boulevard (to be completed by summer of 2025), Imperial Highway, and Florence Avenue; Traffic Signal upgrades at Rosecrans Avenue, Gardendale Street, Alameda Street, and Cecilia St/5th Street (this project was recently completed in the summer of 2024); Street and Traffic Signal Improvements on Lakewood Boulevard between Century Boulevard and Gardendale Street;
Downey Avenue (South of Firestone Boulevard): Intersection improvement at Firestone Boulevard (to be completed by summer of 2025);
Cecilia Street: As mentioned previously, a speed hump project shared between the City and Norwalk was recently approved by the Norwalk City Council. This project should be completed by summer of 2025 by the City of Norwalk. it is the lead agency with the City of Downey paying its prorated share of between 40 and 50 percent for the construction costs.
Recommended Projects for HSIP Funding Applications
Municipalities commonly use funding available from the Highway Safety Improvement Program (HSIP) to help fund traffic safety projects. Considering this, another purpose of the LRSP is to analyze and develop the project scopes and cost estimates that would be competitive for HSIP funding using a Benefit-Cost Ratio (BCR) score of at least 20. The project is scored by using safety measures that are outlined by HSIP engineers in the Local Road Safety Manual. The HSIP Analyzer Tool is used to quantify the benefit of a particular safety measure, add up the total quantified benefits for all of the proposed safety measures, and then divide the calculated benefit by the costs to implement the safety measures in order to come up with the BCR score. A BCR score of 20 is what is deemed to be necessary to qualify for HSIP funding in the upcoming Cycle 12. Essentially, this is a tool to help jurisdictions determine how likely they are to be considered for funding under the HSIP program. A list of the seven projects with the potential to receive funding through the HSIP program are listed below:

9 The projects that show “N/A” in the table do not have scores as these are set-aside funds that are available over multiple funding cycles, typically for smaller projects. The City was successful in receiving some of these set-aside funds for pedestrian improvement projects in the last funding cycle.

10 The City has had some success in securing HSIP funds in previous cycles, as previously mentioned. The analyses that were completed by Willdan as part of LRSP 2024 will be used as part of the data-based justifications necessary in the HSIP Cycle 12 funding applications due to Caltrans by September 9, 2024. In order to be competitive under the Cycle 12 application period, staff is seeking adoption of Resolution No. 24-XXXX (Attachment C) by the City Council, which officially recognizes the update commissioned by the City Council and provides the most updated collision data for Caltrans to the City’s application. In addition, staff is seeking adoption of Resolution No. 23-XXXX, which is required for submittal of applications under the HSIP program (Attachment D).
This report highlights the City’s current traffic safety projects that address many of the prioritized projects that are based on the collision data trends in the LRSP 2024. There are other traffic safety projects that might fall just outside of these priorities that are nonetheless important in addressing safety concerns of the community and the City Council. Several such projects that staff is working on or has completed include the following:
• South Downey Safe Routes to School Phase I project that improved sidewalks and curb ramps near Ward Elementary, Carpenter Elementary, Imperial Elementary, Old River Elementary, and Stauffer Middle School.
• Staff was successful in securing a grant from Caltrans under ATP Cycle 6 to create a new project under the Safe Routes to School Project. Phase II of this project is currently in the design phase to provide pedestrian improvements at various locations on the way to the Safe Routes to School Phase I schools mentioned above, as well as Alameda Elementary, Saint Raymond Catholic School, and Sussman Middle School.
• In addition to these school safety projects, staff has begun design of the speed humps along Guatemala Avenue, which was initiated through the City’s Traffic Calming Policy. Staff also completed an analysis of the intersection of Suva Street and Guatemala Avenue. It was determined that a traffic signal is warranted at this intersection and the design phase has begun. It is anticipated that the speed hump project will be completed by June 2025. Design of the traffic signal will be completed by December 2024. The traffic signal project will likely take until the end of 2025 to complete construction, as there are lead times of up to 6 months to order and receive the new traffic signal equipment.
Engineering staff from Public Works also works closely with the Police Department’s traffic safety division as part of its work to conduct traffic studies throughout the City.
These include requesting and reviewing new traffic accident reports to identify recent trends and supplementing existing traffic accident data with any new reports to more fully

11 analyze a specific location. Staff also conducts engineering speed surveys, as required under the California Vehicle Code, to ensure that the posted speed limits on the City’s streets are calculated based on properly collected data so that the Police Department can legally enforce the limits during their patrols. Staff from both departments coordinate closely to ensure that signage and pavement markings are visible to motorists and pedestrians. Enforcement requests from the community that are made to engineering staff are shared with the Police Department so they can increase patrols or deploy mobile enforcement trailers to help reduce speeding. Engineering staff will coordinate with the Police Department to review any new collision or enforcement data on a quarterly basis for the prioritized locations in the LRSP 2024.
Staff will continue to use the information in the LRSP 2024 as it prioritizes traffic safety projects as part of its Capital Improvement Program in order to meet the goal of reducing traffic collisions throughout the City. Caltrans recommends updating the LRSP every four years, so the effort to update the plan in 2024 rather than 2026 demonstrates the City Council’s commitment to continually evaluating traffic safety throughout the City.

I- Introduction
I- Introduction
The Downey LRSP1 provides a conceptual framework to identify, analyze, and prioritize roadway safety improvements on local roads. Particularly, it provides the opportunity to proactively correct high collision or problem locations and prevent local road fatalities and injuries. It establishes goals, objectives, and emphasis areas. Furthermore, it helps identify appropriate funding sources to reach the City’s safety-related visions and goals.
Beginning in 2021, Caltrans2 requires agencies to have completed an LRSP in order to apply for HSIP3 funding which is a common source of safety project support from the State and Federal Government. Fortunately, the City was awarded grant funding to implement this very LRSP. It has been prepared in accordance with all Caltrans and FHWA4 requirements. Additionally, the City has outlined some of its own goals and visions for the LRSP:
Table I-1: Goals & Visions Outlined by Downey

Data Analysis Methodology
7 8
The quantitative analysis is the process of compiling and studying collision records.
SWITRS and TIMS are very common and reliable sources for collision records. Using this data, we can identify which locations have the greatest number of collisions, the most severe collisions, the collisions with the most injuries, and that have a significant number of certain types of collisions. We also specifically examine collision data involving pedestrians and bicyclists to see if any patterns are prevalent. As the d ata is being reviewed, we consider which mitigations, countermeasures, or strategies can be used to reduce the likelihood of certain types of collisions. We are then able to identify types of locations where collisions in the future are likely to occur and sort them into different projects. Each project employs mitigations specific to those locations. As we identify locations, we share our findings with the Task Force.
7 Statewide Integrated Traffic Records System (SWITRS). SWITRS provides crash data from police or sheriff reports with details including date, time of day, location, number of cars, type of crash, lighting conditions, collision factors, injuries, and injury severity. 8 University of California Berkley’s Transportation Injury Mapping System (TIMS). TIMS uses data from SWITRS to generate interactive maps that provide a better perspective where crashes are occurring. TIMS also eliminates non-injury crashes from its data.

I- Introduction
In addition to in person field reviews and observations, the qualitative analysis considers existing conditions on the roadways as well as insight and input from the Task Force for identifying other factors that might not be understood from the data. Projects are then refined to emphasize safety and accessibility for all.
Both the quantitative analysis and qualitative analysis are used to develop data -driven safety projects that the Task Force support.
II- High Priority Area/ Challenge Areas: Intersections/ Corridors, and Ped/Bike Safety
II- High Priority Area/ Challenge Areas: Intersections/ Corridors, and Ped/Bike Safety
The 6-year collision data was filtered to include only collisions that took place on roadways maintained and operated by the City. The data was studied to identify locations that had a significant number of collisions, injury collisions, and instances of specific types of collisions. Using SWITRS and TIMS, locations with many collisions, locations with high severity collisions, or both can be difficult to spot when simply studying data. To better locate them, a heat map was developed and can be found on the inside cover of this report. Also, collisions involving bicyclists and pedestrians were isolated to determine if any prevailing patterns could be identified.
Severity Trends
When considering all the data, it is important to identify overall trends. Figure II-1 illustrates the proportion of collisions based on the different severity categories. Severity is a significant consideration when applying for project funding , particularly collisions involving injuries. There were 3,272 collisions reported in Downey between 2020 and Figure II-1: Citywide Collisions by Severity

2023. The combined fatal and severe injury collisions made 2% of the total collisions reported, while the collisions without injury made up for 40% of the collisions reported.
A comparison of the total number of fatal and severe injury collisions amongst nearby cities is shown in Figure II-2. This comparison shows that Downey has less fatal and severe injuries than nearby cities of Norwalk, Bellflower, Santa Fe Springs, and Lynwood.
However, Downey has an annual average between 10 -28 fatal and severe injury collisions per year.

Comparative to the fatal and severe injury collision map, Figure II-3 shows the total number of fatal and all types of injury collisions compared with nearby cities. Downy is amongst the Cities with the highest amount of collisions with Bell Gardens, Pico Rivera, Cudahy, and Paramount having less collisions than Downey.

Pedestrian and Bicycle Trends
Reviewing trends involving pedestrians and bicyclists is pertinent to reach the City’s goal of zero traffic-related deaths. Although pedestrian and bicycle related crashes only take 7% of the City’s crashes, they should be considered a priority as crashes involving pedestrians and bicyclists are more likely to result in fatal or severe injury collisions than crashes only involving motorized vehicles. Figure II-8 shows the severity of pedestrians and bicycle collisions compared to all other collision types, showing if a pedestrian is involved in a crash, it is much more likely to result in a fatality or severe injury.
Pedestrian Crash Trends
Between 2020 and 2023, there were 138 pedestrian crashes in the City of Downey, with 12% of the crashes resulting in a fatality or severe injury, as displayed in Figure II-8. All injury collisions involving pedestrians are shown in the map in Figure II-9. A complete table of the crashes involving pedestrians is found in Appendix X.

Crash Priority Methodology
Building on the overall collision analysis for 2020-2023, specific locations were studied.
The top intersections considered were based on the following metrics:
• Intersection collisions include those occurring either at or within 250 feet of the intersection.
• Intersections were sorted by the sum of the weighted collision severity. Weighted crash severity is a value assigned based on the crash severity. The values shown in Table II-6 are assigned for each type of crash severity. These crash severity weighted values were based on the HSIP analyzer to identify the project benefit.
A high weighted collision severity coupled with the low number of collisions indicates that the collision is more likely to be severe or fatal.
Table II-6: Weighted Crash Severity Values
Property
Damage Only
Complaint of
Pain Other Injury Severe Injury Fatal
1 6 11 126 126
• Intersection locations where collisions have been recently mitigated with infrastructure projects were removed from this analysis and are not included in the top intersections list. This includes locations that have had projects funded by past HSIP calls for projects.

Top 10 Intersections
Table II-7 lists the top 10 intersections with the highest weighted severity based on the metrics listed above. A deeper look into each location and possible mitigations can be found in Section III- Top Intersection and Corridor Spotlight.
Every intersection in the top 10 intersections with the highest weighted severity has a trend of mostly broadside collisions. Common primary collision factors that occurred at these intersections are automobile right of way violations, unsafe speeding and improper turning. These trends are consistent with the Citywide trends identified earlier in the report.

IV- Project Scopes
IV- Project Scopes
A list of potential project locations was developed considering the intersections and corridors with the highest weighted severity collisions and with the help of the Task Force.
These locations were then compared and grouped based on a systemic approach.
Because a LRSP is required for HSIP funding and has related objectives and goals, all of these projects were developed for HSIP funding.
The HSIP program has requirements to be eligible to compete for HSIP funding. These include:
• The total project costs must be greater than $100,000 for competitive BCR9 applications
• The BCR must be over 4.0
• Mitigations or project scopes must be selected from the LRSM10
A variety of methods to determine viable project scopes were used. Consideration was made of the locations of fatal and severe injury crashes, high-density crash locations, and the countermeasures identified to address the City’s safety issues. The LRSM was used to identify countermeasures to address qualitative and quantitative safety measures and select viable projects for the LRSP.
The project’s BCR must be calculated using the HSIP Analyzer11 by inputting the crashes and their severity, and the project’s cost estimate. Projects are weighed and selectively chosen by their BCR to compete for limited grant funding.
The BCR threshold of projects that were funded through previous HSIP funding cycles has been increasing recently. Projects in last cycle’s HSIP cycle 11 required a BCR of
9 Benefit-Cost Ratio (BCR) For some of the projects the cost summary will include a BCR value depending on the likely funding source. BCR is an important figure for determining the effectiveness of a proposed project. The benefit is based on many factors including collision history, collision severity, systemic approach, the crash reduction factor associated with the applied countermeasures, and whether the types of collisions can be mitigated with countermeasures being applied for the project. A higher BCR is considered a more favorable project.
10 Local Roadway Safety Manual (LRSM) is a document published by Caltrans identifying HSIP eligible mitigation measures, their collision reduction factors, and what type of collisions are most impacted by the mitigation measures. The mitigation measures are referred as countermeasures. The latest LRSM version and version 1.7 used in the LRSP is from April 2024.
11 HSIP Analyzer is a required document for HSIP projects which determines the project’s benefit based on the total crashes within the project area and their crash severity. The HSIP Analyzer is a tool used to calculate the project BCR.

18.0 and above to be awarded funding. Due to the increasing BCR threshold, projects with a BCR of 20.0 and above were considered competitive in this analysis.
A total of 7 project scopes were proposed with a BCR over 20.0 and met the minimum requested project cost. Each proposed project has a BCR that is historically competitive in HSIP funding.

Overview
The Firestone Corridor Traffic Signal Improvements project was developed based on guidelines and funding eligibility of HSIP Cycle 12. The Firestone Corridor Traffic Signal Improvements project scope consists of the following LRSM Countermeasures:
2024 LRSM
Countermeasure ID Countermeasure Description
SI02 Upgrade Signal Hardware
SI18PB Pedestrian Countdown Heads
S22PB Modify Signal Timing to Implement an
LPI12
The upgrade signal hardware countermeasure will provide better visibility of intersection signals and will aid drivers’ advance perception of the upcoming intersection. This countermeasure involves upgrading signal back plates, larger signal heads, relocating signal heads or adding additional signal heads to an intersection.
A pedestrian countdown signal contains a timer display and counts down the number of seconds left to finish crossing the street. Countdown signals can reassure pedestrians who are in the crosswalk when the flashing “DON’T WALK” interval appears that they still have time to finish crossing. These signals have been shown to encourage more pedestrians to use the pushbutton.
An LPI gives pedestrians the opportunity to enter the intersection 3 -7 seconds before vehicles are given a green indication. With this head start, pedestrians can better establish their presence in the crosswalk before vehicles have priority to turn left o r right through the crosswalk. LPIs provide increased visibility of crossing pedestrians, reduce conflicts between pedestrians and vehicles, increase the likelihood of motorists yielding to pedestrians, and enhance safety for pedestrians who may be slower to start into the intersection.
12 Leading Pedestrian Interval (LPI) gives pedestrians the opportunity to enter an intersection 3 -7 seconds before vehicles are given a green indication.
100- Firestone Corridor Traffic Signal Improvements
The proposed scope of work is to:
Based on the LRSP analysis, the Firestone Boulevard corridor is the second highest weighted collision corridor in the City and four of the intersections (Firestone Boulevard/ Lakewood Boulevard, Firestone Boulevard/ Downey Avenue, Firestone Boulevard/ Rives Avenue, and Firestone Boulevard/ Ryerson Avenue) are in the top 10 highest weighted collision intersections in the City. These trends highlighted Firestone Boulevard as a corridor to investigate for LRSP project selection. In meetings with the Task Force , staff was interested in prioritizing signal upgrades to all the signalized intersections on Firestone Boulevard. Figure 100-1 identifies the 15 signalized intersections on Firestone Boulevard within Downey City Limits.
Scope of Work:
Upgrade signal hardware, upgrade to pedestrian countdown signal heads, and implement a leading pedestrian interval to the corridor timing at the following 15 signalized intersections on Firestone Boulevard within the Downey City Limits.
1. Firestone Boulevard & Arnett Street
2. Firestone Boulevard & Ryerson Avenue

Project Area Collision Trends
The Firestone Boulevard corridor is the second highest ranked roadway segment in the City and includes four of the top collision intersections from this LRSP analysis.
The LRSM identifies that signalized intersections with a high frequency of broadside and rear-end crashes that occur because drivers are unable to see traffic signal sufficiently in advance to safely negotiate the intersection being approached can be mitig ated with improving the signal hardware. There is a 15% collision reduction factor when upgrading traffic signal hardware.
The LRSM identifies that pedestrian countdown signal heads should be installed at signalized intersections where pedestrian vs. vehicle collisions have been reported. There is a 25% collision reduction factor in pedestrian and bicycle crashes with the inst allation of pedestrian countdown signal heads.
The LRSM identifies that LPIs should be installed in intersections with signalized pedestrian crossings that have high turning vehicular volumes and have had pedestrian vs. vehicle crashes. There is a 60% collision reduction factor in pedestrian and bicycl e crashes with the installation of LPIs.
At the 15 intersections identified in the scope of work, SWITRS data indicated that there were 357 collisions between 2020 and 2023. The HSIP Analyzer was used to calculate
100- Firestone Corridor Traffic Signal Improvements
the project benefit including these 357 total collisions broken down by collision severity, shown in Table 100-2.

200- Pedestrian Crosswalk Set Aside
200- Pedestrian Crosswalk Set Aside
Overview
The City of Downey applied for Pedestrian set -aside funding in HSIP Cycle 11 in 2022, using the scope of work identified in the 2022 LRSP. There is still one location identified that has yet to be funded, shown below in the proposed scope of work.
The Pedestrian Crosswalk Set Aside project was developed based on guidelines and historic funding eligibility of HSIP Cycle 12. The set-aside funding category is only available for certain types of safety projects, including pedestrian crossing enhancements. The maximum funding available for pedestrian crossing enhancements is $350,000. This funding can be awarded to a City one time per HSIP cycle and is typically awarded to any agency that requests it. This type of funding does not require a BCR calculation or detailed collision data. The Pedestrian Crosswalk Set Aside project scope consists of upgrading existing uncontrolled pedestrian crosswalks with RRFB 13, high visibility signage, and high visibility striping. The project scope consists of the following countermeasure:
2024 HSIP Funding Set-asides
Set-aside for Pedestrian Crosswalk
Enhancements
Upgrading pedestrian crossings will improve safety for pedestrians and biyclists. The enhanced pedestrian crossings make motorists more aware of pedestrians in the roadway at uncontrolled crosswalk locations. The proposed scope of work is to:
13 Rectangular Rapid Flashing Beacon (RRFB)
Scope of Work:
Upgrade existing uncontrolled pedestrian crosswalks at 2 locations. Upgrades include bulb-outs, RRFBs, advance overhead flashing beacons, and high visibility signing and striping.
• Rives Avenue at Adwen Street
• Conrad Street at Montgomery Street
200- Pedestrian Crosswalk Set Aside
Bulb-outs and curb extensions narrow the roadway to create a shorter distance for pedestrians to cross. Also, the narrowed roadway leads motorists to driving slower. The RRFBs, over-head flashing beacons, and high visibility striping make it easier for dri vers to see crossings and pedestrians in the roadway. An example of signing and striping enhancements can be found at the crosswalk on Brookshire Avenue at Everest Street in the City of Downey. The improvements include RRFBs, advance overhead flashing beacons, signs and pavement markings include a yield bar and “Slow School Crossing” and “Wait Here” pavement markings and signs, shown in Figure 200-1.
Figure 200-1: Example of pedestrian crosswalk enhancements on Brookshire Avenue at Everest Street
Task Force members were present in the development of this project and shared school crosswalk locations which could benefit most from these enhancements and ensure that all recommendations are consistent with the City’s Road and Street Standards. These discussions helped determine the crosswalks prioritized for this project. The following list of uncontrolled crosswalks were identified for pedestrian crossing enhancements from the Task Force meeting:

Overview
The Systemic Bike Lane Corridor project was developed based on the City of Downey Bicycle Master Plan and collision history. The Systemic Bike Lane Corridor project scope consists of the following LRSM Countermeasure(s):
2024 LRSM Countermeasure ID Countermeasure Description
R33PB
and/or Bike Safety Set Aside Install bike lanes
A bike lane project can get funding either through a traditional BCR HSIP application or using the Bicycle Safety Set Aside project funding based on eligibility of HSIP Cycle 12.
The set-aside funding category is only available for certain types of safety projects, including installing bike lanes. The maximum funding available for bicycle safety is $350,000. This funding can be awarded to a City one time per HSIP cycle and is typically awarded to any agency that requests it. This type of funding does not re quire a BCR calculation or detailed collision data. Due to only Downey Avenue having a recent collision history along the project corridor, it is recommended to break this project into two HSIP applications in order to optimize the amount of funding that can be secured.
This countermeasure is used on roadway segments with crashes between bicycles and vehicles or crashes that may be preventable with a buffer/ shoulder. Most studies suggest that bike lanes may provide protection against bicycle/motor vehicle collisions. Str iped bike lanes can be incorporated into a roadway when it is desirable to delineate which available road space is for exclusive or preferential use by bicyclists. The scope of work for this project is listed below:
300- Systemic Bike Lane Corridor
These four proposed segments are good candidates for Class II bike lanes based on their collision history and are identified as planned bicycle projects in the Downey Bicycle Master Plan. Based on input from the Task Force, it is imperative to keep on -street parking in place on these segments. The proposed bike lanes will be installed by implementing a lane reduction on these segments by reducing the through lanes to one lane in each direction and installing a two-way left turn lane in the middle of the roadway to make available space for the bike lanes and on -street parking. The intersection lane configuration should remain in place to avoid congestion on these three segments.
Figure 300-1 Highlights the locations of the 4 proposed bike lane segments in the City of Downey overlaid on the City of Downey’s Bicycle Master Plan map. The Bicycle Master Plan Map identifies where existing bicycle facilities are and shows how these proposed bike lanes will close gaps in the bicycle system.
Scope of Work:
Install Class II bike lanes with a lane reduction, keeping parking at the following 4 roadway segments:
• Using a BCR Application:
o Downey Avenue between Firestone and the South City Limit • Using a Bike Safety Set Aside Application:
o Old River School Road between Firestone Place and Florence Avenue o Brookshire Avenue between Imperial Highway and Iowa Street o Foster Road between Lakewood Boulevard and the East City Limit

The third scenario is the optimal scenario for the City to apply for HSIP Cycle 12 funding.
This countermeasure is eligible for 90% funding through HSIP. Therefore, the City would have to provide a local match of $ 59,720 to receive funding for this project. An expanded cost estimate is included in Appendix III.
It should be noted that historically, HSIP has $350,000 of set aside funding available that each City can apply for in each funding cycle. This set aside funding is typically awarded to any jurisdiction that applies for it. The City may be awarded the maximum set aside funding each HSIP Cycle for consecutive HSIP Cycles, if the City wishes to apply for pedestrian crossing enhancement funding in phases.
300- Systemic Bike Lane Corridor
Existing Conditions
The existing roadway conditions on the three segments are shown in the figures below:
Figure 300-2: The existing roadway configuration on Old River School Road between Firestone Boulevard and Florence Avenue. There are currently two through lanes in each direction with parking on both sides of the street and cyclists share the road with motor vehicles. The proposed project will reduce the roadway to one through lane in each direction with parking and bike lanes on both sides of the street, and a two-way left turn lane. This proposed bike lane segment is consistent with the planned bike lane with road diet identified in the Downey Bicycle Master Plan.

This proposed bike lane will be a gap closure, connecting with the existing bike route on Gardendale Street.
300- Systemic Bike Lane Corridor
South of the proposed Brookshire Avenue segment on Brookshire Avenue between Gardendale Street and Imperial Highway, there are existing bike lanes with a road diet, shown in Figure 300-6. The proposed bike lanes with a road diet on the 3 proposed segments will look very similar to this existing stretch.
Project Area Collision Trends
The countermeasures for the Systemic Bike Lane Corridor project provide improvements for pedestrians and bicyclists. However, this means only collisions involving pedestrians and bicyclists can be considered. The LRSM identifies that installing bike lanes would likely provide a 35% collision reduction factor for pedestrian and bicycle related collisions.
Bike lanes will reduce the width of travel lanes and likely have a traffic calming effect. The HSIP Analyzer was used to calculate the project benefit including the 5 total bicycle and pedestrian and bicycle-involved collisions broken down by severity below in Table 300-
3. Only Downey Avenue had reported bicycle or pedestrian involved collisions within the project area.

400- Systemic Traffic Signal Improvement Project
400- Systemic Traffic Signal Improvement Project
Overview
The Systemic Traffic Signal Improvement Project was developed based on a systemic approach of selecting intersections with outdated signal hardware throughout the City of Downey and selecting 8 intersections that could be upgraded to a protected left turn phase from protected permissive from the top 10 intersections identified in the collision analysis. This project consists of 19 signalized intersections. The project scope consists of the following LRSM Countermeasures:

400- Systemic Traffic Signal Improvement Project
This countermeasure will improve visibility of traffic signals for motorists to see from greater distances. The proposed scope of work is as follows:
The upgrade signal hardware countermeasure will provide better visibility of intersection signals and will aid drivers’ advance perception of the upcoming intersection. This countermeasure involves upgrading signal back plates, larger signal heads, relocat ing signal heads or providing additional signal heads to an intersection. Figure 400-1 identifies the location of the 11 intersections that will receive traffic signal improvements.
Scope of Work:
Remove and replace existing traffic signal hardware with upgraded hardware at the 1 2 intersections listed below. These upgrades include 12-inch traffic signal heads where 8-inch traffic signal heads are still in use and new signal backplates that will replace signals with missing, faded, or damaged backplates.

400- Systemic Traffic Signal Improvement Project
The protected left turn phase countermeasure will improve the safety for left-turn maneuvers by removing the need for drivers to navigate through gaps in oncoming/ opposing through vehicles. Where left-turn pockets are not protected the pedestrian and bicyclist crossing phase often conflicts with these left-turn movements. Drivers focused on navigating the gaps of oncoming cars may not anticipate or perceive the non - motorized users. Figure 400-1 identifies the location of the 8 intersections that will receive protected left turn phasing improvements.

Project Area Collision Trends
The City of Downey’s collision data included in this project occurred at or within 250 feet from the intersection.
The LRSM identifies that signalized intersections with a high frequency of broadside and rear-end crashes that occur because drivers are unable to see traffic signal sufficiently in advance to safely negotiate the intersection being approached can be mitig ated with improving the signal hardware. There is a 15% collision reduction factor when upgrading traffic signal hardware.
The LRSM identifies that providing protected left turn phases would likely mitigate rear - end, sideswipe and broadside crashes. There is a 30% collision reduction factor when providing protected left turn phasing to an intersection.
At the 19 intersections identified in the scope of work, there were 229 collisions between 2020 and 2023. The HSIP Analyzer was used to calculate the project benefit including these 329 total collisions broken down by severity in Table 400-2.

39% of the collision types (shown in Figure 400-8) were broadside collisions. The second most common type was a rear-end collision. Upgrading the signal hardware and providing protected left turn phasing is best used on signalized intersections with a high frequency of broadside and rear-end crashes.
400- Systemic Traffic Signal Improvement Project
Figure 400-8: Collision Types at the 19 Project Intersections Using the HSIP Cycle 12 BCR Analyzer, the calculated benefit for the project is shown in Table 100-3. The project benefit is $50,424,888, so a BCR of 20 would allow for this project to cost up to $2,521,244.

500- Florence Median Project
Overview
Florence Avenue corridor has the 5th highest collision weighted value in the City. The Florence Median project was developed based on recommendations from the Task Force. The project scope consists of the following LRSM Countermeasures:
2024 LRSM
Countermeasure ID Countermeasure Description
R08 Install raised median
Installing raised medians is an effective strategy in reducing head on, sideswipe and broadside collisions outside of intersections as it reallocates the existing cross section to incorporate a buffer between the opposing travel lanes and reinforces the limits of the travel lane. Raised medians may also be used to limit unsafe turing movements along a roadway.
Based on comments from the Task Force, the emergency services departments should be invited to comment throughout the design process of this project to ensure emergency vehicles will have space to move through this segment. The concept map of the proposed raised median is below in Figure 500-1.
Scope of Work:
Install a raised median on Florence Avenue between Vultee Avenue and Woodruff Avenue.

This countermeasure is eligible for 90% funding through HSIP. Therefore, the City would have to provide a local match of $ 55,510 to receive funding for this project. An expanded cost estimate is included in Appendix V.
Existing Conditions
Florence Avenue currently has three through lanes in each direction with a painted median separating directions of travel. The third travel lane acts as a parking lane during off-peak hours. Florence Avenue fronts some apartment complexes and a church with in the project segment. The painted median does not allow left -turning movements mid- block.

Project Area Collision Trends
The countermeasure for the Florence Median Project reduces the possibility of midblock collisions. The countermeasure to install raised medians is best used in areas experiencing head-on collisions that may be affected by both the number of vehicles that cross the centerline and by the speed of oncoming vehicles. The LRSM identifies that the installing raised medians would likely provide a 25% collision reduction factor for mid - block collisions.
The HSIP Analyzer was used to calculate the project benefit including the 25 total collisions broken down by severity below. The collisions identified in the table below were from a 4.6 year period, with the years 2020 and 2021 skipped due to lower collision rates due to the change in traffic conditions from the COVID-19 pandemic. The highest possible project benefit identified 25 collisions between 7/3/2016 -9/14/2019, skipping 2020 and 2021, and including collisions between 1/5/2022-6/1/2023.

600- Sidewalk Install Project
600- Sidewalk Install Project
Overview
This project was identified from the spot location analysis when reviewing the top 10 corridors with the highest weighted collision severity between 2020 and 2023. This project needs to be further discussed with the Task Force before proceeding with finalizing the project and prioritizing it. The project scope consists of the following LRSM Countermeasures:
2024 LRSM
Countermeasure ID Countermeasure Description
R20 Convert from two-way to one-way
traffic
R35PB Install sidewalk/pathway (to avoid
walking along roadway)
NS23PB
Install pedestrian crossing at
uncontrolled locations with
enhanced safety features
The top ranked corridor was along Klondike Avenue with a severe injury collision involving a pedestrian. The 7th ranked corridor along Vista Del Rio Drive showed similar characteristics to Klondike Avenue, so these two locations were combined to make a systemic project. Installing raised medians is an effective strategy in reducing head on, sideswipe and broadside collisions outside of intersections as it reallocates the existing cross section to incorporate a buffer between the opposing travel lanes and reinforces the limits of the travel lane. Raised medians may also be used to limit unsafe turing movements along a roadway.
600- Sidewalk Install Project
Project Area Collision Trends
Two severe injury/ fatal collisions were identified within the project limits of Klondike Avenue and Vista Del Rio Drive. Both of these collisions involved a pedestrian walking in the street.
Using the HSIP Cycle 12 BCR Analyzer, the calculated benefit for the project is shown in Table 600-1. The project benefit is $41,219,379, so a BCR of 20 would allow for this project to cost up to $2,408,720.
Table 600-1: Project Benefit by Countermeasures

R35PB: Install sidewalk $26,230,356
R20: Convert from two-way traffic to one-way traffic $6,955,019 Total $41,219,379
Scope of Work:
Install a sidewalk on the following 3 roadways:
1. Klondike Avenue (both sides of the roadway)
2. Bixler Avenue (both sides of the roadway)
3. Vista Del Rio Drive (one side of the roadway)
To accommodate the sidewalk width and keep parking on Klondike Avenue and Bixler Avenue, both parallel roadways will be converted to opposing one -way streets.
A high visibility crosswalk will be installed at the intersection of Vista Del Rio Drive at Lemoran Avenue where the pedestrian bridge leads into the roadway.
V- Next Steps
V- Next Steps
The objective of this chapter is to account for safety ideas that were not able to be developed into projects. Some of these ideas came from the goals and visions outlined by the City, discussions with the Task Force, and data analysis. These ideas can evo lve when reviewing future data and how the emphasis of state funding progresses. Also, these ideas can be coupled with new trends that may emerge.
Citywide Lighting Program: City Staff had interest in reducing night time collisions with a project that would install lighting across dark corridors in the City. However, there was a very low night-time collision rate. Future collision data should be monitored for new collision trends showing an increase in night-time collisions in unlit corridors within the City.
This has been revisited and there were only 20 reported collisions occurring at night with no street lights on the roadway. Of the 3,266 collisions reported Citywide between 2020 and 2023, this only effects less than 1% of the total collisions
This report should be re-evaluated and updated every few years. New collision trends can develop with time and should be evaluated, and projects and programs relating to new trends should be proactively developed to reach the City’s safety visions and goal s. and goals.

Countermeasure and Project Review
Meeting Minutes
September 22, 2021
Attendees: Nicolle, Jeff, Ed, Amaka
- Top Intersections & Corridors Review (see Attached tables for summary and comments)
- Countermeasure Selection Review (see Attached project table for summary) o Look into a street lighting project on Alameda Street and Old River School Road. This is a top priority to the City to install street lighting midblock.
The City already did a LED lighting conversion to City-owned street lighting.
▪ The below map identifies the night-time collisions that occurred in the City between 2015-2019 where there were no street lights, or street lights were not functioning. There were only 26 collisions that occurred Citywide in the 5-year study period where there were no street lights at the crash site. All of those 26 collisions were property damage only collisions. Any street lighting project will not be competitive in HSIP due to the low number of collisions Citywide.
▪ Edison owns 2/3 of the street lights in the City. The city owns the other 1/3.
o Brookshire- stick with the first project
o Pedestrian crossing project- construction costs are skyrocketing. ▪ Willdan will develop a prioritized list of locations for a set aside project
o Traffic signal project- inflate construction costs
o Paramount Gardendale project is complete- remove from list o Firestone- add hardware and controller/detection upgrades to the project o Firestone median project- Willdan can look into breaking the project into segments/ hot spots to make a lower cost project to inflate the BCR to be more competitive.
o Willdan will prioritize street lighting and the Firestone corridor projects, then other projects will be prioritized based on BCR.
- Next Steps
o Core Team meetings. Incorporate stakeholders from the following:
▪ Police Department
▪ Fire Department
▪ School Districts
▪ Parks and Recreation Department
▪ Bike Coalition
▪ Community Development Department
▪ PIH Hospital or Keiser Permanente
o Draft Report complete in November
- Action Items:
o City of Downey- will contact stakeholders listed below to set up a meeting in October
▪ Police Department
▪ Fire Department
▪ School Districts
▪ Parks and Recreation Department
▪ Bike Coalition
▪ Community Development Department
▪ PIH Hospital or Keiser Permanente
o Willdan- will continue to develop and prioritize projects for the LRSP and will check in on the first week of October to schedule the first stakeholder meeting.

Good project opportunity- signal upgrades & speed feedback signs. -- Medians constructed 8 years ago. Lakewood Boulevard to Old River School Road has some median openings.

There were
only 2
collisions at
Woodruff/ Hall
in a 12-month
period so the
traffic signal
warrant would
not be met for
HISP purposes.
Woodruff at Hall Road (stop
controlled currently) could
be a good candidate for a
traffic signal project. There
are a lot of trucks going
through there with lots of
broadside collisions. Vertical
curve causes visibility issues
