The TxDOT Roadway Inventory is a statewide dataset of attribute data routed to TxDOT's roadway network linework using linear referencing. Roadways are dynamically segmented whenever a single attribute changes, resulting in a highly segmented network that can be queried and filtered for specific attribute values. Attributes such as functional system, traffic counts, surface type, speed limits and many more are contained within. This layer is published annually based on end-of-year data that is reported to the Federal Highway Administration. This layer is highly segmented and thus in a different format than most of our regularly published datasets, which are segmented based on a single attribute. The TxDOT Roadway Inventory layer can also be found on txdot.gov and TxDOT’s Open Data Portal. This product is created annually by the Transportation Planning and Programming Division at TxDOT in the Data Analysis, Mapping and Reporting Branch for internal and public use.Last Revision: 09/12/2024TxDOT Roadway Inventory Specifications 2023 AGO OverviewTxDOT Roadway Inventory Specifications 2023 PDF link in AGO Update Frequency: 1 YearsSource: Geospatial Roadway Inventory Database (GRID)Security Level: PublicOwned by TxDOT: TrueRelated LinksData Dictionary PDF [Generated 2025/04/24]
