If you’ve seen talk about a white traffic light or images of a signal with an unfamiliar fourth color, you’re not imagining it. With everything drivers already pay attention to at intersections, ...

If you're comfortable with the present green, amber, and red traffic lights, be prepared to get uncomfortable. New research suggests that adding a white light will speed up traffic and improve safety ...

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 ...

Development of self-driving technology seems to have slowed down due to the complexity of navigating human-driven traffic. A new paper from the Institute of Electrical and Electronics Engineers ...

As more self-driving cars enter roadways around the world, many aspects of driving could change forever. More electric vehicles (EVs) and autonomous vehicles (AV) are already leading engineers to ...

The classic traffic signal design was internationally recognized in 1931. The ubiquity of stop lights’ Red-Yellow-Green phases aren’t just coincidence—they’re actually codified in an international ...

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 ...

The first tri-color traffic signal that was invented and used in Detroit. (The Henry Ford.) On this day in 1920, the way people drove was changed forever when a Detroit traffic cop installed a ...

If you've ever wondered how traffic lights work and how they can detect your car, you've probably also been curious about those small blue lights mounted above the signals themselves. These blue ...
