Transportation System Performance

Congestion & Reliability Performance Report

This performance measure report is for internal use to help MDOT regions, Transportation Service Centers (TSCs), and planners expand their knowledge on how Michigan freeways are operating over time and how they compare to each other. This information helps identify congested areas, when congestion occurs and how often, corridor rankings, cause of delay, and more. The report is only a starting point, with the potential for a more in depth analysis. If your area has plans to share this information externally, contact the Congestion and Mobility Unit to ensure the correct measures are being used. Each performance measure provides a view of how freeways may be operating. Looking at it from many perspectives can give a more complete picture and better understanding of what is going on.
