How do you find average daily traffic?
Annual Average Daily Traffic (AADT) is one of the most important parameters in transportation engineering. It is calculated by adding the total vehicle volume of a highway for a year divided by 365 days.
What do you mean by average daily traffic?
Average Daily Traffic (ADT) means the volume of traffic passing a point or segment of a road, in both directions, during a period of time, divided by the number of days in the period and factored to represent an estimate of traffic volume for an average day of the year.

What is VMT used for?
Vehicle miles traveled (VMT) is a measure used extensively in transportation planning for a variety of purposes. It measures the amount of travel for all vehicles in a geographic region over a given period of time, typically a one-year period. It is calculated as the sum of the number of miles traveled by each vehicle.
