TxDOT annually collects, on average, 82,000 short-term traffic volume counts and around 1,000 vehicle classification counts. These short-term counts are augmented by over 300 permanent count locations that collect data 24 hours a day, 365 days a year. Annual average daily traffic (AADT) can be viewed in the District Traffic and Urban Saturation Web Map, and additional traffic data statistics are available in the STARS II System.
District Traffic Urban and Saturation Count Web Map
The district traffic and urban saturation web map displays AADTs on TxDOT maintained roads, county roads and city streets that were collected in the reporting year. Counts include frontage roads when present. This is a user-friendly web map that displays AADTs on state owned and non-state owned roads where data is available. To request maps for additional historical data years, please contact TPP Traffic Section.

Statewide Traffic Analysis and Reporting System (STARS II) is a TPP Statewide Traffic Monitoring Program database with detailed traffic data and statistics.
