Annual Average Daily Traffic (AADT) Maps

Annual Average Daily Traffic (AADT) maps provide traffic volumes based on a 24-hour, two-directional count at a given location. Raw traffic data is mathematically adjusted for vehicle type, determined by an axle correction factor. The data is then statistically corrected by a seasonal variation factor that considers time of year and day of the week.

To see the traffic history of any count station, please remember the Station Count Location Number and open the site - https://www.tdot.tn.gov/APPLICATIONS/traffichistory. At the top of the map in the yellow box of the Traffic History site, choose the County Name and enter the Station Number, then click on “Search.”
