flag Louisiana proposes white traffic light phase to boost self-driving car efficiency and cut delays and fuel use.

flag Louisiana researchers propose adding a white light to traffic signals to improve efficiency for self-driving cars, signaling human drivers to follow the vehicle ahead. flag The white phase could reduce travel delays by up to 10% when half of vehicles are autonomous and cut fuel use by 13% at 90% autonomy. flag The change would not alter existing traffic laws for human drivers but aims to support the growing use of connected and autonomous vehicles through smarter traffic systems.
