Benefit Summary HTML

The Multipath Signal Phase and Timing (SPAT) Broadcast Project demonstrated the Safe Green Passage traffic signal application, which provides speed guidance to an approaching driver so that a vehicle may safely pass through the green phase of an upcoming traffic signal. This is accomplished by the signal system’s ability to send SPAT information to approaching vehicles even when they are several miles or multiple signals away. The simulation performed to evaluate performance of the Safe Green Passage application used three intersections along Grand River in Novi, Michigan (Drake Road, Halstead Road, and an M-5 exit ramp). This site was chosen because accurate signal timing information was available. Field testing of the application occurred at two signalized intersections in Oakland County, Michigan.
