Adding a fourth light to traffic signals would not only be good for autonomous vehicles and human drivers, it would also benefit pedestrians.

Self-driving cars that are "connected" can cut down on travel time, but when they don't communicate, AVs can actually slow things down.

Researchers used fMRI to test ideas about complex decision-making.

Self-driving cars fall short when it comes to understanding the social codes in traffic that tell human drivers to yield or continue driving.

An extra light on traffic signals could let self-driving cars control traffic flow and give a heads up to human drivers.

Our existing social contract around driving should apply to automated vehicles, say researchers, essentially solving the "trolley problem."

A technique that allows autonomous cars to make relevant calculations more quickly showed it improves both traffic and safety in simulated situations.

Ordinary objects like bikes and cones on the side of the road can cause driverless cars to stop abruptly, report researchers.

What are the ramifications of the first US felony prosecution of a fatal crash involving a Tesla driver-assist system? A law professor weighs in.

"Our new paper defines how light interacts with microscale concave interfaces." The material may be useful for autonomous vehicles.
