Description from the original website

State highway agencies collect traffic volume data through both temporary traffic counting and continuous traffic counting programs and report their continuous counting data to FHWA on a monthly basis. Data listed here are reported by states following data format prescribed in FHWA's 2001 Traffic Monitoring Guide. Starting with the 2020 datasets, the traffic monitoring data released is piped delimited, quality reviewed and used in the Traffic Volume Trends (TVT) process with the same field names as contained in the 2001 TMG (the original data [prior to 2020] with the rigid fixed column format).
