Traffic Monitoring Information System (TMIS)

The Michigan Department of Transportation has completed the process of replacing the TMIS website with a new site with improved user experience. During the transition to this new site, traffic information on the TMIS site was not updated after March 20, 2017.

The new site, Transportation Data Management System (TDMS) is now available. Traffic count information dating back to 2008 from TMIS has been migrated into TDMS.

Traffic data is no longer available through the TMIS website.
Additional questions, please contact Kevin Krzeminski (517)335-2274 or Edward Potter (517)335-2942.
