What does ADT stand for in transportation engineering?

In transportation engineering, ADT stands for Average Daily Traffic. This term is crucial as it refers to the total volume of vehicle traffic on a highway or road segment averaged over a typical day. Understanding ADT is important for traffic management, roadway design, and planning, as it helps engineers and planners assess traffic patterns and determine the capacity needs of road infrastructure.

The concept of Average Daily Traffic is used in various applications, including the evaluation of roadway performance, the analysis of safety data, and making decisions related to construction and maintenance. By calculating ADT, engineers can identify trends in traffic flow and make informed decisions regarding upgrades or alterations to roadways to improve safety and efficiency.

This understanding of ADT supports effective planning and resource allocation in transportation projects, ensuring that roads can handle current and future traffic demands.
