If implemented, the white traffic light might reshape people's behavior in a world where more driverless vehicles travel on public roads. However, the chances of this happening are slim.

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 ...

Researchers propose fourth traffic signal light for hypothetical self-driving car future It's called 'white' for now, until a color that 'does not create confusion' is picked. Andrew Paul ...
