Traffic lights might see a fourth signal as self-driving cars become more practical. Getty Images/iStockphoto. The researcher’s latest plans differ from a 2020 model of a four-light intersection.

Current traffic control methods, such as traffic lights, have limited effectiveness in reducing delays and congestion. Expand to continue reading ↓ Sign up for our weekly tech digest.

Their ability to communicate with each other and traffic control systems makes the whole thing go quickly and smoothly. But that’s only the case when there aren’t human drivers in the mix.

The Uasin Gishu government has completed the installation of traffic lights on major road junctions in Eldoret City to help control the flow of increasing vehicles.The installation has been going ...

In order to optimize traffic flow, many autonomous vehicles communicate with one another and with traffic control systems. Scientists are now suggesting that an extra white light at intersections ...

NEW BRAUNFELS, Texas — In an effort to enhance traffic management and safety, the New Braunfels City Council has approved a contract to update the city's advanced traffic management system. The ...

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 ...

Red, amber, green – traffic lights are pretty much the same the world over, and have been for more than a century. However, they could one day have a fourth colour added to help traffic flow ...

These simulators are showing researchers that traffic improves with the presence of AVs and a fourth traffic light and that fuel consumption is much lower as there is much less stop-and-go movement.

The tech giant is working with 13 cities around the world — with Seattle being the first in the U.S. — to help optimize traffic lights and make traffic flow more efficiently.
