A traffic monitoring system that reads Bluetooth signals from mobile devices inside cars is being implemented around Boston and other cities to predict highway travel times through construction zones and on highways.
The BlueTOAD traffic-monitoring system was created by TrafficCast, Madison, Wis. "It's very, very accurate," says Taylor Stukes, senior engineer of information technology services with KCUS Consulting, Boston. "We're covering roads from Boston to Cape Cod with it, and MassDOT has aggressive expansion planned for the program."
