A “white light” added to traffic signals could enable self-driving vehicles to help control traffic flow—and let human drivers know what’s going on. In computational simulations, the new approach ...

Traffic signal timing technology from the University of Michigan could cut down on congestion, To operate, the system uses vehicle Global Positioning System data. Traffic signal timing technology that ...

Inductive loop detectors were introduced in the early 1960s and have been one of the most widely used sensors for traffic management on freeways, arterials, and intersections. These sensors are used ...

A surprising amount of technology might be making that red light hold you up. Here's how traffic lights detect (or don't detect) your vehicle.
