White light will indicate that AVs are planning their movements in order to improve the flow of traffic through the intersection

Green denotes "go," yellow denotes "slow down," and red denotes "stop" in terms of the regulations of the road. But those fundamental traffic laws could change as artificial intelligence becomes more prevalent.
Researchers from North Carolina State University suggest introducing a white light as a fourth colour to traffic signals so that autonomous vehicles can help manage traffic flow and inform other drivers of what is happening.

Researchers from North Carolina State University suggest introducing a white light as a fourth colour to traffic signals so that autonomous vehicles can help manage traffic flow and inform other drivers of what is happening.
The addition of this fourth white light dramatically reduced fuel usage and increased travel time through intersections, according to a series of computer simulations conducted by the study's authors.
This concept were proposing for traffic intersections, which we call a white phase, taps into the computing power of autonomous vehicles (AVs) themselves, said Ali Hajbabaie, corresponding author of the paper and an associate professor of civil, construction and environmental engineering at NC State, in a university release.

I remember reading a long time ago that traffic lights are not actually "red" and "green"...

...due to the high prevalence of red-green color blindness in humans, but rather off shades designed to thwart red-green color blindness.
