Will Another Color Be Added to Traffic Lights?

In a future where self-driving cars race up and down our busy streets, a fourth color could be added to traffic lights. At this point, researchers at North Carolina State University propose a white traffic light system based on the intelligent management of traffic flow by autonomous vehicles. Self-driving cars and trucks won’t have to “look” at the white traffic light because they’ll be communicating with it wirelessly. White Light Project Relies on Computing Power of Autonomous Vehicles“Red lights will continue to mean stop, green lights will continue to mean go. If 70 percent of the vehicles in traffic are autonomous vehicles, the intersection can operate in fully automatic white phase mode.
