Annual Average Daily Traffic (AADT) volume is useful for the project planning process to predict and provide projected future traffic volume. The given below is the annual average daily traffic AADT formula which shows you how to calculate the annual average daily traffic on your own. From the AADT equation, it is obvious that annual average daily traffic is the total volume of vehicle traffic of a highway or road for a year divided by 365 days.

Where,

V = Total Volume of Vehicle Traffic for a Year

This annual average daily traffic AADT formula will be a very useful one for the public welfare department (PWD) officers to plan the traffic and take necessary measures to improve the infrastructure.
