County annual average daily traffic (AADT) maps
Following recent enhancements to the Iowa Traffic Data online interactive map, the production of static City and County Annual Average Daily Traffic (AADT) maps has been discontinued. We encourage users to reference the Iowa Traffic Data online interactive map for comprehensive traffic information.
Information about the Iowa DOT’s traffic counting process, traffic reports, and vehicle classification can be found here. For additional traffic information, or to request a static PDF map, contact Jorge Zamora at 515-239-1323 or or Jorge.Zamora@iowadot.us.
