Traffic Data

Traffic Monitoring provides for the collection, retention and analysis of data, which indicates the volumes, classification, weights, speeds and other characteristics of motor vehicles that traverse South Dakota highways and streets. This information is necessary for assessing pavement life, pavement design, geometrics, and safety analysis. Traffic movement data is collected at over 7,500 locations throughout the state. In order to maximize data collection efficiency, sampling techniques and automatic recording equipment are utilized whenever possible.
