TxDOT 5-Year Counts 2024

Historical Data from 2024 This is a public and downloadable traffic data product of statewide average annual daily traffic (AADT) counts. Annual average daily traffic is a measure of transportation system use that represents the typical traffic volume at a location. Standard traffic monitoring AADT calculation methods vary depending on traffic data collection equipment, data type, and frequency. The TxDOT AADT count data in this layer is calculated as 24 hour volume pneumatic tube count x Axle Correction Factor x Monthly Adjustment Factor. In a small number of cases, other methods may be used at TxDOT's discretion.
