City annual average daily traffic (AADT) maps
City and county traffic maps are updated every four years. We also provide statewide vehicular, truck and interstate traffic maps, as well as interactive statewide traffic maps for all roadways and the turning movement counts for select intersections. Information about the Iowa DOT’s traffic counting process, traffic reports and vehicle classification can be found here.
