High-tech system manages County traffic flow

The Road Commission for Oakland County’s FAST-TRAC system is evolving to optimize the management of traffic flow on 675 signaled road intersections throughout the county.

Although FAST-TRAC, an acronym for Faster And Safer Travel Through Routing and Advanced Controls, started out in 1992 with just 28 intersections located in Troy, the high-tech system has since grown in prominence and capability across the county. The system is composed of video image processing programmed to respond to actual traffic flow and regional computers that monitor and adjust traffic along major roads, also taking accidents into account.

“It adjusts the green time based on traffic flow, and it also provides progression along corridors,” said Road Commission signal systems engineer Danielle Deneau.

Originally, funding for the system came from $55 million in federal money with a required local match of 20 percent but now FAST-TRAC is converting to full federal funding, which is a welcomed change for the county’s residents.


“‘I was here before SCATS and FAST-TRAC, and believe me, traffic used to be just horrible,’ Rochester Hills Council member James Rosen said. ‘In the mid-80s through mid-90s, the traffic times on Adams Road heading northbound were agonizing. It could be an hour from M-59 to Tienken Road. Nowadays, it’s a lot better. One of the things I notice, every once in awhile, you see a signal that is haywire.'”
