Highway Safety Improvement Program

SRTS Toolkit

The California Department of Transportation (Caltrans) administers the Highway Safety Improvement Program (HSIP), a core federal-aid program. The purpose of the Highway Safety Improvement Program is to achieve a significant reduction in traffic fatalities and serious injuries on all public roads, including non-State-owned public roads and roads on tribal land, and rural roadways functionally classified as a rural major or minor collector, or rural local road.

Highway Safety Improvement Program applications are scored solely on a project’s benefit-cost ratio, a calculation that utilizes crash data. The higher the benefit-cost, the more competitive the project is for funding. Highway Safety Improvement Program funding has been successfully used to support safe routes to school projects where crash data exists on routes to school. Additionally, an Highway Safety Improvement Program funded project could be located at one or multiple locations benefiting a single school, multiple schools, or district-wide.


Caltrans is encouraging a proactive and systemic method for these applications.  If there is a location with a history of injuries or fatalities, improvements at other locations that have similar roadway characteristics should also be considered in the application, even if injuries or fatalities have not occurred there yet. 

Cities, counties and tribal governments are eligible for this funding.  This means that school districts would need to partner with one of these agencies to submit an application.
