With the advent of autonomous vehicles on the roads of the world, a fourth traffic light may soon appear – white. According to Gismeteo, it will help control traffic, save time and fuel.
According to the author of the project, Ali Khadzhbabai, the red signal, as before, will indicate a stop, the green one will allow you to start moving, and the white one will recommend ordinary car drivers to simply follow the car in front of them.
If several unmanned vehicles drive up to the intersection, they will coordinate the best traffic flow based on their own computing power, and the white light will tell the person to follow this plan. If there are no drones nearby, the traffic will be controlled by signals of the traditional three colors.
When tested on a small simulation using computer models, white light accelerated traffic by a small but significant amount when autonomous vehicles accounted for 10–30% of total vehicles.
The concept will significantly speed up traffic lights, as self-driving cars will be able to determine the best course of action compared to a simple start-stop system.
