Office of Highway System Information and Performance (OHSIP)


This office collects and analyzes report statistics related to the fiscal status, physical and geometric extent, performance, and designation of the State's roadway systems. This enables decision makers and system users to take advantage of quality transportation information to make performance-based decisions about transportation services and infrastructure.

What We Do:

  • Administer public roads functional classification and designation approvals to secure and distribute State and federal funding;
  • Manage naming of State roadways, structures, and appurtenances;
  • Partner with federal and local agencies, managing urban and rural area designations and maintains the official California Road System map set;
  • Maintain Condition and performance data in the Federally mandated Highway Performance Monitoring System (HPMS), and officially certifies the annual report on maintained public road mileage for the State of California; and
  • Support performance-based decision making by exercising leadership in implementing Transportation System Performance Measures at the national, state, and regional levels.
