A motion-detecting camera, LiDar scanner, infrared sensor, weather probe, and sound detector variously measure pedestrian and traffic counts, air quality, odd noises, and vehicles turning in the wrong ...

Researchers have developed a smart sensor for DARPA that’s capable of identifying infrared -- without having to have its own power source.

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.

Traffic signals equipped with pre-emption systems bear a telltale infrared sensor mounted on top. View Slideshow If you've ever been stuck in traffic longing for a magic box that could turn all ...

Traffic lights with artificial intelligence could improve traffic flows in cities, advocates say.

The technology could also help improve safety by transmitting information about traffic conditions directly to the driver. Volkswagen and Siemens are using sensors to detect pedestrians and ...
