TxDOT 24hr Truck Volume and Percent

This is a public and downloadable traffic data product providing a 24-hour snapshot of commercial vehicle activity across the statewide roadway network. Unlike annual averages, this layer focuses exclusively on truck traffic volumes and percentages recorded over a single 24-hour period. The data includes detailed classification breakdowns to distinguish between specific truck types and configurations. The values in this layer represent raw 24-hour truck counts and are not adjusted by monthly or axle correction factors. Calculation methods vary based on the specific classification equipment used at each monitoring site, or by other approved data collection procedures at TxDOT's discretion.
