- 2009 Traffic Volumes [Michigan]
- Description
- The Annual Average Daily Traffic (AADT) is the estimated mean daily traffic volume and the Commercial Annual Average Daily Traffic (CAADT) is the estimated mean daily traffic volume for commercial vehicles. For continuous sites, estimates are calculated by summing the Annual Average Days of the Week and dividing by seven. For short-count sites, estimates are made by factoring a short count using seasonal and day-of-week adjustment factors. Data Coverage: The dataset covers the entire Federal Aid System in the State of Michigan. Update Cycle: AADT & CAADT volumes are created and released every year.
