The researchers first introduced a “white phase” traffic intersection concept in 2020. What’s important is that there be a signal that is clearly identifiable by drivers.” “And, just to be clear, the color of the ‘white light’ doesn’t matter.

But we think it is important to incorporate the white light concept at intersections because it tells human drivers what’s going on, so that they know what they are supposed to do as they approach the intersection.

“It can be used to coordinate traffic in any scenario involving AVs. “Granting some of the traffic flow control to the AVs is a relatively new idea, called the mobile control paradigm,” Hajbabaie says. When too many vehicles approaching the intersection are being controlled by drivers, rather than AVs, the traffic light would revert to the conventional green-yellow-red signal pattern. Any non-automated vehicles – those being driven by a person – would simply be required to follow the vehicle in front of them: if the car in front of them stops, they stop if the car in front of them goes through the intersection, they go through the intersection. The white light is a signal that AVs are coordinating their movement to facilitate traffic through the intersection more efficiently. When enough AVs are approaching the intersection, this would activate the white light. The white phase concept rests on the fact that it is possible for AVs to communicate wirelessly with both each other and the computer controlling the traffic signal. And white lights will tell human drivers to simply follow the car in front of them.” “The white phase concept also incorporates a new traffic signal, so that human drivers know what they are supposed to do.

“This concept we’re proposing for traffic intersections, which we call a ‘white phase,’ taps into the computing power of autonomous vehicles (AVs) themselves,” says Ali Hajbabaie, corresponding author of the paper and an associate professor of civil, construction and environmental engineering at NC State. In computational simulations, the new approach significantly improves travel time through intersections and reduces fuel consumption. But transportation engineers at North Carolina State University are now proposing a “white light,” which would enable autonomous vehicles to help control traffic flow – and let human drivers know what’s going on.
