MDOT analyzes and reports on TIM performance on a monthly and annual basis. Once implemented, MDOT will be able to filter, track, and analyze the total number of secondary crashes, those resulting from previous crashes, and those resulting from previous incidents. MDOT has worked with the MSP to create an online training course for the new crash report. There is also an option for the officer to manually enter a more relevant circumstance, if necessary. Under this category, law enforcement officers are able to choose up to two circumstances from the following pre-defined list: prior crash, backup due to regular congestion, backup due to other incident, glare, traffic control device inoperative or missing, or shoulders. On January 1, 2016, the state of Michigan implemented a revised traffic crash report that now allows law enforcement officers to designate a crash as secondary under a “contributing circumstances” category.

Operators at the WMTOC capture and record secondary crashes through visual verification on the CCTVs. Having data from both the TOC and the CAD system provides increased incident awareness, and the data and information about each incident are more accurate as compared to the data from just one of the systems. Operations at the TOC are able to review the information from the CAD system as it comes in and subsequently enter the relevant information into the ATMS. In Southeast Michigan, the MSP are co-located with the DOT at the SEMTOC, and they share a (non-integrated) computer-aided dispatch (CAD) feed. There have been discussions about collecting data for all three TIM performance measures statewide.ĭata for TIM performance reporting are gathered at the TOCs and entered into the advanced traffic management system (ATMS) by TOC operators. The SEMTOC collects data and reports on roadway clearance time (RCT) and incident clearance time (ICT), and the statewide TOC collects data and reports on ICT only. The WMTOC has collected data and reported on all three national TIM performance measures since 2010. The team works together to find comprehensive solutions to traffic safety challenges that are being experienced throughout the state. This team has a broad representation of local, state, federal, and private partners – including DOT staff, police, and various other first responders – and is an emphasis area in the Strategic Highway Safety Plan. Also, the Governor’s Traffic Safety Advisory Commission works in collaboration with the Michigan Statewide TIM Action Team, which meets every other month. These coalition meetings have a wide variety of representation, including the Michigan State Police (MSP), the Southeast Michigan Council of Governments (SEMCOG), the city of Detroit, AAA Michigan, Emergency Road Response, Michigan State University, the Federal Highway Administration (FHWA), WWJ news station, and other surrounding city and county governments. MDOT hosts Metro Detroit Incident Management coalition meetings in Detroit quarterly and annually. Figure 1 shows the coverage areas for each of the TOCs in Michigan, including the Blue Water Bridge TOC in Port Huron. In addition to traffic and incident management activities at the SEMTOC, the Detroit-area Freeway Courtesy Patrol (FCP) covers 300 miles of freeway operates 24 hours, 7 days a week and averages about 50,000 assists per year. Also, because the WMTOC only operates during daytime hours, the STOC covers overnight operations in the Grand Region.
The STOC covers the remaining five regions in the state (Southwest, University, Bay, North, and Superior Regions). The Statewide TOC (STOC) covers approximately 1200 miles of freeways and operates around the clock, every day of the year. The WMTOC is monitored 14 hours a day on weekdays and 8 hours a day on weekends. The Western Michigan TOC (WMTOC) covers 45 miles of freeways and 18 miles of non-freeway state trunkline in eight counties in the Grand Rapids and Grand Haven areas (Grand Region). The SEMTOC is staffed 24 hours a day, 7 days a week. The Southeastern Michigan TOC (SEMTOC) covers 200 miles of freeways around the Detroit metropolitan area (Metro Region). The Michigan Department of Transportation (MDOT) operates three traffic operations centers (TOC) – two regional TOCs and one statewide TOC.
