Caltrans Uses Local Road Safety Manual to Improve its Data-driven Approach to Statewide Safety Project Selection

Publication Year:

Summary from Assessment of Local Road Safety Funding, Training, and Technical Assistance: Benefit/Cost Tool and Local Road Safety Manual


Background

Fifty percent of California's Highway Safety Improvement Program (HSIP) funds are dedicated to local roads. The approximately $100 million-per-year program is managed by the Caltrans Division of Local Assistance (DLA), which is responsible for programming the funds to local road safety projects. As a part of the process, DLA sets criteria for HSIP project applications, reviews applications for accuracy, and selects projects. The division does not identify the projects for the local jurisdictions or administer the projects once selected, but instead provides guidance, tools, and training so the local jurisdictions are empowered to make informed decisions on effective safety improvements.

When the HSIP program first started, the application process was very basic, but has evolved into a data-driven process. To improve Caltrans's overall data-driven approach to statewide safety project selection and to maximize the long-term safety improvements across California, DLA developed Local Roadway Safety: A Manual for California’s Local Road Owners. The manual provides an easy-to-use, straightforward, comprehensive framework of the steps and analysis tools local jurisdictions would need to proactively identify locations with roadway safety issues and the appropriate countermeasures.

Benefits

Developing this resource has improved local agencies' ability to perform benefit/cost calculations for project applications. Two-and-a-half years ago, the average benefit/cost ratio on a project was approximately 8, but currently it is approximately 13.5. Local agencies are submitting applications for projects with greater lifesaving benefits. Local agencies understand the necessity of the data-driven process. The division also has seen an increase in positive communication with local agencies.
