Traffic Monitoring Information System (TMIS)

The Michigan Department of Transportation is in the process of replacing the TMIS website with a new site with improved user experience. As we transition to this new site, traffic information on the TMIS site will not be updated after March 20, 2017. This transition will be occurring as the collection program transitions into the 2017 collection season. The TMIS site will continue to provide historical traffic information for the next year.
Additional questions, please contact Kevin Krzeminski (517)335-2274 or Edward Potter (517)335-2942.
