There are approximately 230 traffic data collection sites with permanent traffic data collection devices or Automatic Traffic Recorders (ATR) in the state of Georgia. These devices count the number of vehicles 7 days a week, 24 hours a day, 365 days a year. In addition to permanent counters, there are over 9,000 portable traffic collection devices across Georgia as well. Collected traffic data is used for calculating the Annual Average Daily Traffic (AADT) estimates, determining traffic patterns, and aid in the development of plans for traffic alleviation purposes.
