Travel Monitoring Analysis System Stations Table

The Travel Monitoring Analysis System (TMAS) - Stations Table dataset was compiled on December 31, 2024 and was published on September 25, 2025 from the Federal Highway Administration (FHWA), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The data included in this table have been collected by the FHWA from State DOTs through 24/7 permanent count data. The attributes are used by FHWA for its Travel Monitoring Analysis System and external agencies and have been intentionally limited to location referencing attributes since the core station description attribute data are contained within TMAS. The attributes in the Station data correspond with the Station file format found in Chapter 6 of the 2001 Traffic Monitoring Guide (https://doi.org/10.21949/1519109). A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529084
