TRAFFIC COUNTS
Vehicle volume data (number of vehicles on any given roadway section) are collected by machines at approximately 4000 locations across the state. Of these locations, 44 sites are equipped in such a way that enables the collection of vehicle volumes by type of vehicle (e.g. motorcycles, passenger cars, and various sizes of trucks). At 30 sites, the instruments are also able to automatically weigh vehicles. Depending on the type of site, traffic is monitored anywhere from 24 hours to continually throughout the year. The continual traffic counters are referred to as Automatic Traffic Recorders (ATRs) and a report of the traffic data collected at these 58 sites can be viewed in the links below. Hard copies of this report are available for $10 each by calling 406.444.7217.



The TDCS also collects speed data at 41 sites and vehicle occupancy on a limited basis. A hardcopy of a report entitled Traffic By Sections is published every year. It includes weighted traffic volumes by specific route segments on all routes of the National Highway, Primary, Secondary and Urban highway systems. Hard copies of this report are available for $50 each by calling 406.444.7217.
