What is Annual average daily traffic?
'''Annual average daily traffic''', abbreviated '''AADT''', is a measure used primarily in transportation planning and transportation engineering. Traditionally, it is the total volume of vehicle traffic of a [[highway]] or [[road]] for a year divided by 365 days. AADT is a useful and simple measurement of how busy the road is. Newer advances from traffic data providers are now providing AADT by side of the road, by day of week and by time of day.
