Traffic Counts (Model)

Feature layer containing authoritative traffic count points for the traffic model for Sioux Falls, South Dakota. The data in the traffic counts model feature layer is collected for traffic count modeling and transportation planning. This data is collected on a five-to-seven-year basis, with data from 2001, 2008, 2013, 2018, and 2023. The traffic counts are 24-hour, weekday, two-directional counts. Traffic counts are normally collected during the summer months, but may be taken any season, as weather permits. The traffic counts are factored by the day of the week as well as by the month of the year to become an Average Annual Daily Total (AADT). Traffic volumes (i.e., count data) can fluctuate depending on the month, week, day of collection, the weather, type of road surface, nearby construction, etc. All the historical data should be averaged to reflect the "normal" traffic count. More specific count data (time, date, hourly volume) can be obtained from the Sioux Falls Engineering Division at 605-367-8601.
