Here’s the truth that most drivers don’t think about: creating new traffic signals isn’t nearly as easy as it looks.

Traffic engineers are quietly working on a radical idea: adding a white signal to the familiar red, yellow, and green. Instead of signaling drivers directly, the extra light would tell humans when to ...

BUFFALO, N.Y. — Technology already installed at hundreds of Western New York intersections — with plans to dramatically expand — will be able to give priority to emergency vehicles and transit, ...

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 ...

What do you think of a fourth traffic light color being added to traffic signals for self-driving vehicles to help control traffic flow? I get that one day a bunch of connected autonomous cars may ...

Microwave radar sensors gained popularity before and during World War II for object detection. Radar sensors are non-intrusive equipment that transmits electromagnetic signals and receives echoes or ...

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 ...
