The aim is to reduce phantom traffic jams — the start-and-stop congestion on crowded roads that has no obvious cause.

In a study, the cars' cruise control was modified to react to the overall flow of traffic using artificial intelligence. The aim is to influence a phenomenon called a phantom traffic jam — the start-and-stop congestion on crowded roads that has no obvious cause. (AP Photo/Mark Humphrey)
