Robotaxis And Driverless Cars Need A Fourth Traffic Light

Cars that drive themselves are no longer just a concept you’d see in sci-fi movies imagining the near future. Companies like Waymo are already using self-driving cars, and you can ride in a robotaxi in various U.S. cities now. The road infrastructure may need to adapt to accommodate the growing fleets of autonomous vehicles (AVs) in the coming years. A team of transportation engineers at North Carolina State University has been working on one part of said infrastructure since 2020: adding a fourth traffic light, which they suggest could be white (though it could really be any new color).
