Caltrans highway sequence listing The goal of this project was to explore development of methods that would facilitate data extraction from TCRs and automate or semi-automate the collision postmile coding and sequence of events coding of TCRs. The postmile, once established, becomes a permanent record and/or address in the highway database. What do Odometer values specify? Each route is linearly referenced by PM as well as an odometer reading. Enter the coordinates to find the PM info of the location (s). This research study also investigated automatic population of other items in the TASAS accident database including generating accident summaries, latitude and longitude information for Oct 16, 2006 · The TASAS Branch generates a TSN Highway Sequence Listing for all 12 Districts. Caltrans is awaiting final approval of those listings. The results will display a red dot which indicates the location of the typed coords, and the green flags which indicate the result (s) Aug 22, 2021 · The Route 33 and Route 71 exits were missed when the list was created. The unit performs location coding and sequence of event coding for crashes delivered to Caltrans by CHP and local law enforcement agencies. OHSIP provides transportation data from TSN to state and federal legislators, the Governor’s office, and FHWA for determining transportation funding for California Highway System and meeting federal Functional Classification is used in determining eligibility for Federal funding programs. Oct 17, 2025 · The Caltrans All Roads Linear Referencing Services (LRS) dataset provides the base geometry for federally required Highway Performance Monitoring System (HPMS) business data, functionally classified roads for the California Roads System (CRS) (a requirement for federal funding of local agency projects), and the State Highway Network (SHN), which supports a wide range of internal Caltrans Click Image To Enlarge The California Department of Transportation (Caltrans) is responsible for planning, design, construction, maintenance and operation of the state highway system. California Road System (CRS) maps - The FHWA stamp of approval is in the lower left corner of each CRS The Crash Coding and Data Analysis Branch coordinates with the California Highway Patrol (CHP) and Caltrans IT to collect and process crash on or associated with a State highway facility.

State-furnished materials and expenses, as well as supplemental work items and descriptions. If you wish to increase/decrease the search from the location of the coordinates, enter a new tolerance. Each segment is coded with the district, county, route, postmile prefix (if any), begin postmile, end postmile, and postmile suffix Oct 16, 2006 · Transportation System Network (TSN) database. How do I validate post miles? Validate post miles by using Caltrans’ Highway Sequence Listing and/or Caltrans’ GIS Services’ Postmile Tool. Default tolerance is 32 feet (10 meter) from the coords entered. Incorrectly reported exits - There are a number of exits that just simply do not exist or are somehow incorrectly listed. Contract Cost Data Item Code SearchEnter the item description of the code you wish to search for: (You may enter part of the word or the whole phrase) All items. . The State Odometer is a distance reading (in miles) with the beginning of the route as zero. Postmiles are coded with the district, county, route, postmile prefix (if any), postmile, and postmile suffix (if any). This listing is used throughout Caltrans to identify projects or reference locations along a State Highway. The Federal Highway Administration (FHWA) identifies functional classification as a key item in transportation data. Each record represents a segment of California state highway where the county, route, postmile prefix, and postmile suffix are unchanging, and there are no gaps or overlaps in the postmiles. Standard contract items and descriptions for Caltrans projects. The source of data is the Caltrans TSN 7. The "Highway Sequence Listing" formerly referred to, as the "California State Highway Log" and the "California Log of Bridges on State Highways" should be used to identify post mile of reference points used in a project. The Office of Highway System Information and Performance collects, manages, and maintains the Transportation System Network (TSN) data systems. The TASAS Branch generates a TSN Highway Sequence Listing for all 12 Districts. The materials included on these lists are authorized for use on Caltrans construction projects. Each segment is coded with the district, county, route, postmile prefix (if any), begin postmile, end postmile, and postmile suffix Jan 3, 2020 · Highway Sequence Listing (aka Postmile Log) Collision Coding Unit Collision Data on California State Highways -Annual collision summaries on SHS Division of Traffic Operations (DTO) Reports Traffic Data Branch Annual Publications for Traffic Volumes and Truck Volumes Traffic Volumes Authorized Materials Lists (AML) Authorized Material Lists are specified in Caltrans specifications and are primarily a proactive measure used in conjunction with other acceptance activities as outlined in Department standards and guidance documents. Department of TransportationWelcome to the Postmile Services Postmile Query Tool postmile or geo-coordinate.

District 7, which includes Los Angeles and Ventura counties, has the second largest workforce of the 12 Caltrans districts statewide. Route 125 is still under construction, and they are awaiting a final list of all exits. Streets and highways are grouped into classes according to the service they provide.
