Annual average daily traffic, abbreviated AADT, is a measure used primarily in transportation planning, transportation engineering and retail location selection. Traditionally, it is the total volume of vehicle traffic of a highway or road for a year divided by 365 days. AADT is a simple, but useful, measurement of how busy the road is.
AADT is the standard measurement for vehicle traffic load on a section of road, and the basis for some decisions regarding transport planning, or to the environmental hazards of pollution related to road transport.[1][2]
