What is the Highway Safety Improvement Program?

The Highway Safety Improvement Program (HSIP) is a core federal-aid program with the purpose to achieve a significant reduction in traffic fatalities and serious injuries on all public roads. The HSIP is legislated under Section 148 of Title 23, United Stated Code (23 U.S.C. 148) and regulated under Part 924 of Title 23. The California HSIP consists of three primary components:

  • Strategic Highway Safety Plan (SHSP) - development is led by Caltrans in concert with other federal/state/local and private safety partners; the SHSP is a major component and requirement of the Highway Safety Improvement Program (23 U.S.C. § 148). It is a statewide-coordinated safety plan that provides a comprehensive framework for reducing fatalities and serious injuries on all public roads. The SHSP identifies California’s key safety needs and guides investment decisions towards strategies and countermeasures with the most potential to save lives and prevent injuries.
  • Program of Highway Safety Improvement Projects
    • State Highway System – HSIP funds are allocated to and administered by Caltrans Division of Financial Programming. Caltrans Division of Traffic Operations is the program manager for safety projects on the State Highway System which account for 15,100 centerline miles.
    • Non-State Highway – administered by Caltrans Division of Local Assistance for local roadways which account for 159,630 centerline miles.

  • Railroad-Highway Grade Crossing Program – jointly administered by the California Public Utilities Commission and Caltrans Division of Rail and Mass Transportation, it generates a program of highway safety improvement projects at railroad-highway grade crossings, which are funded via a set-aside from the HSIP apportionment.
