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.
