East Avenue O Bike Lane Project East Avenue O Bike Lane Project Scope: Widen roadway and install bike lanes Total Project Cost: $791,000 Benefit/Cost ratio of 7.36 LA County HSIP Grants9
10
Project Case Study #1 Project Inception Obtained pedestrian and bicycle related Statewide Integrated Traffic Records System (SWITRS) collisions for the last 10 years from tims.berkeley.edu Performed GIS analysis to identify proposed bike lanes in the 2012 Los Angeles County Bicycle Master Plan that had the highest rates of pedestrian and bicycle related collisions. 10LA County HSIP Grants
11
Project Case Study #1 Benefit/Cost Ratio Calculation Benefit/Cost Ratio Calculation Selection of project corridors: Select bike lanes proposed in the bike plan where safety improvements are required to reduce pedestrian and bicycle related collisions. Identification of countermeasure: Based on the collision data, bicycle lanes along widened shoulders was selected as the preferred countermeasure for reducing future collisions and fatalities 11LA County HSIP Grants

Project Case Study #1 Benefit Calculation: TIMS site tims.berkeley.edu 12LA County HSIP Grants
13
Project Case Study #1 B/C Ratio Calculation: TIMS site was used to calculate the benefit to cost ratio, where a higher B/C Ratio improved funding eligibility. 13LA County HSIP Grants

Project Case Study #2 Bouquet Canyon Road and San Francisquito Canyon Road Improvements Project Scope: Install guardrails, centerline rumble strips/stripes, and/or recessed pavement markers Total Project Cost: $1,132,000 Benefit/Cost ratio of 25.0 17LA County HSIP Grants
18
Project Case Study #2 Project Inception Project Inception Due to community concerns regarding high number of collisions and speeding along Bouquet Canyon and San Francisquito Canyon Roads, the County of Los Angeles conducted a Road Safety Audit (RSA) on these roadways. Recommendations from the RSA spearheaded the effort to apply for the Cycle 6 HSIP Grant. 18LA County HSIP Grants

Typical LA County Process The County obtains the CHP traffic collision reports for collisions within the unincorporated County areas and codes them in our in-house database. The information in these reports are utilized in various ways to assist us in identifying those areas that should be evaluated to determine if safety enhancements are recommended, including : LA County HSIP Grants26
27
Typical LA County Process Traffic studies that are conducted in response to requests for traffic control devices from the public. The County initiates traffic studies to determine if improvements are recommended following all collisions that resulted in fatal and/or severe injuries, as noted in the CHP reports. LA County HSIP Grants27
28
Typical LA County Process The County’s collision database generates reports annually to identify intersections with a recurrence of a specific collision pattern. The County will then evaluate the “top 5 percent” of patterns found to determine if improvements are recommended. In addition, the County will review patterns, regardless of ranking, when a location is included in an upcoming road construction project. 28LA County HSIP Grants
29
Typical LA County Process Each year the County calculates the collision rates for rural and mountain roadways that have an ADT of 2,000 vehicles or more and at least 2 miles in length. For roadways where the actual collision rates exceed the expected/average collision rates for similar roadways, Road Safety Audits may be performed. The County’s crash rate calculation for Year 2014 are listed on the ftp site located at: ftp://dpw.co.la.ca.us/pub/PDD/AACE LA County HSIP Grants29
