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.

Drivers traveling along South Rampart across Canal Street have just 10 seconds to make it through the stoplight.

RTMS is usually positioned at the side of the road, sensing perpendicular to the movement of traffic. Available sensors like the Sx-300 boast capabilities like “per-lane presence as well as ...

Mercedes-Benz has just received approval to add a fourth color: turquoise blue lights that indicate when a Mercedes car is driving itself. Only California and Nevada have approved the new light color.

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 ...

Researchers propose fourth traffic signal light for hypothetical self-driving car future It's called 'white' for now, until a color that 'does not create confusion' is picked. By Andrew Paul ...

The adventurous motorist thus tries to trick these sensors by rapidly flashing his car's high beams as he approaches a red-lighted intersection, and voilà — the light turns from red to green ...

The sensors feed information about road use to traffic light controllers. The vulnerabilities mean that data can be monitored or changed, researcher Cesar Cerrudo said.

Local authorities are responsible for a great many tasks and regulatory actions in their communities, and one of those responsibilities is the maintenance of traffic lights. Red light sensors are ...
