What is AADT (Annual Average Daily Traffic) in Traffic Engineering?

Annual Average Daily Traffic (AADT) is one of the most fundamental measures in traffic engineering and transportation planning. It represents the average number of vehicles that travel on a roadway segment each day over the course of an entire year. Put simply, it is a way to smooth out traffic variations across weekdays, weekends, and […]

Understanding the K-Factor in Traffic Engineering

In traffic engineering, the K-factor is a critical parameter used in roadway design and traffic analysis. It represents the proportion of Annual Average Daily Traffic (AADT) that occurs during the design hour, and it allows engineers to size and evaluate roadways for their most critical operating conditions.
