Traffic data collection

To collect accurate and continuous traffic data, TxDOT maintains a network of over 350 permanent count sites along various roadway segments throughout the state. The data collected are used to measure the distribution and variation of traffic patterns at a particular roadway segment. 

This data then provides a general description of the roadway segment characteristics, which can then be applied to any similar roadway segment throughout the state. The data collected at each of the permanent count sites provides FHWA and TxDOT with current and past performance, which helps establish future needs and improvements of the various roadway segments in Texas.

Standard sheets

Traffic data collection sheets are for use in major pavement construction projects in truck corridors and construction or maintenance projects impacting existing traffic data collection sites or for new site installations.
