Travel Monitoring Analysis System (TMAS)

Voluntary monthly reporting of agency (state DOT, MPO and/or local agencies) traffic management system data to FHWA through the Travel Monitoring Analysis System (TMAS) is done for their permanent volume, speed, classification, weight and micromobility data (including portable for micromobility) collection sites. Traffic data formats used in TMAS all follow the FHWA Traffic Monitoring Guide (TMG) formats. FHWA is the receiver of all data reported by agencies and TMAS traffic data is provided out to any public user who would need the traffic data. The data submitted through TMAS will provide the amount and nature of vehicular travel at the national, regional, and state levels. The data also provide information on how vehicular travel pattern varies by hour of the day, day of the week, the month of the year, and year to year.
