Average Daily Traffic

« Back to Dictionary Index

Average Daily Traffic (ADT) is a measure used in transportation planning and traffic engineering to quantify the typical traffic volume on a road or section of a road. Here’s how it works:

• Calculation: ADT is calculated by taking the total traffic volume over a specific period (often a week, month, or year) and dividing it by the number of days in that period. This provides an average number of vehicles that pass a certain point on a road each day.
• Usage: ADT is commonly used to assess the capacity, efficiency, and safety of roadways, helping planners and engineers make informed decisions about road design, maintenance, and improvements.

For example, if a road has a total traffic volume of 70,000 vehicles over 7 days, the ADT would be 10,000 vehicles per day (70,000 ÷ 7 = 10,000).
