The Wisconsin Department of Transportation (WisDOT) collects continuous count data from approximately 370 permanent data collection sites primarily located on the State Trunk Highway System. Data at continuous count sites are scheduled to be collected in hourly intervals each day of the year.
Continuous count AADT’s as well as short duration AADT’s dating back to 2001 can be found using TCMap, WisDOT’s interactive traffic count map application.
Please reach out to the DOT Traffic Data Unit for any specific traffic data requests (hourly data, truck data, data prior to 2001, etc).
