Caltrans Fact Booklet (CFB)
DRISI collects and analyzes report statistics related to the fiscal status, physical and geometric extent, performance, and designation of the State's roadway systems. We research and provide ways in which our customers can access, display, and use these statistics. The CFB was formerly the Executive Fact Booklet.
California Quick Facts
California Quick Facts consist of commonly requested information compiled from many different sources within the state, both Caltrans and other California Agencies. Compiled by the Data Analysis and Reporting Branch.
California Road System (CRS) Maps
The California Road System (CRS) Maps display the official functional classification of each road. The Federal Highway Administration [FHWA) identifies functional classification as a key item in transportation data. Streets and highways are grouped into classes according to the service they provide.The functional classification is used by the Federal government in determining funding allocations which help local and State agencies pay for the maintenance of roads throughout their jurisdictions.
Geospatial Information Systems (GIS)
Highway Performance Monitoring System (HPMS) Data
The HPMS is a federally mandated planning study designed by the Federal Highway Administration (FHWA) and implemented as a continuing information system that encompasses data collection, data analysis, and analytical modeling. Authority for the study is vested in Section 307 of Title 23, United States Code.
Highway System Engineering Products Data is in the Office of Highway System Information and Performance.
Data on highways and highway systems, the Strategic Highway Network (STRAHNET), National Highway System (NHS), California Road System (CRS) maps and route descriptions and route numbering for state highways. Highway System Engineering is now part of the Office of Highway System Information and Performance.

Traffic Accident Surveillance and Analysis System (TASAS)
The TASAS Branch maintains TSN (Transportation System Network) database with highway inventory for all State highway facilities in California, which consists of over 15,000 miles of State highways, 15,000 ramps and 17,000 intersections. The inventory data (e.g. district, county, route, post mile, number of lanes, geometric attributes of lanes, shoulders, medians, intersections and ramps) are being continuously maintained and updated on a daily basis.
Travel and Related Factors in California
The Data Analysis and Reporting Branch (DARB) collects many varied data sets and compiles them into impressive reports on California Demographics, California Fuel Usage throughout the State, and California Multi-Modal Transit.
