• More than 150 spread spectrum radio links, and coaxial cable

SEMTOC facilitates area-wide management of traffic through shared connections with:

The system is being continually expanded to include coverage along all Metro Detroit area freeways. ITS devices have expanded on I-94 and I-69 in St. Clair County, providing motorists with real-time information regarding conditions at the Blue Water Bridge and surrounding freeways. MITS will continue to close the gaps of the coverage area in the upcoming years.
