Traverse City — The Michigan Department of Transportation will unveil "smart traffic signals" on a five-mile stretch of Telegraph Road this fall — a move to smooth traffic flow along the busy Oakland County thoroughfare.
The signals, stretching from Nine Mile to 14 Mile roads, will alert drivers of next-generation vehicles about coming red lights and tell them to slow down or speed up to avoid stopping, said Kirk Steudle, director of MDOT.
"In this case, the traffic signal sends out a beacon that says, ‘I’m green and I’m going to be green for 20 seconds,’ " Steudle said. "The car might say on the dashboard, ‘if you go 44 or 42 miles an hour, you will make all the lights.’ "
