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.
Average summer daily trafficEdit
Average summer daily traffic (abbreviated to ASDT) is a similar measure to the annual average daily traffic.
