Cal. SHC § 2331

The Safe, Accountable, Flexible, Efficient Transportation Equity Act-A Legacy for Users of 2005 (Public Law 109-059), also known as SAFETEA-LU, elevated the Highway Safety Improvement Program (HSIP) to a core program (23 U.S.C. Sec. 148). SAFETEA-LU authorized appropriations for programs relating to highway safety improvements that can reduce the number of fatal and serious injury accidents. The core HSIP program includes two set-aside programs: the railway-highway crossing program (23 U.S.C. Sec. 130) and the high-risk rural roads program (23 U.S.C. Sec. 148(f)). The purpose of this chapter is to implement these programs in this state. The commission, the department, boards of supervisors, and city councils are authorized to do all things necessary in their respective jurisdictions to secure and expend federal funds in accordance with the intent of that federal act and this chapter, and to coordinate with local law enforcement agencies’ community policing efforts.
