AI traffic lights predict pedestrians’ crossing behavior

Researchers in Austria have developed a smart AI traffic lights that analyzes pedestrians’ behavior, spots people who are planning to cross the street, and stops the traffic for them without the need to press a button and wait.

AI traffic lights predict pedestrians' crossing behaviorThe system uses cameras that monitor an area measuring eight by five meters. It monitors the movements of people walking near the road, and recognizes an intention to cross within one second.

“After two seconds the estimation becomes reliable,” says Horst Possegger from Vienna’s Institute of Computer Graphics and Vision, which created the system.

If a large group of people are showing an intention to cross, the light can hold the traffic for longer to give them all time to reach the other side safely.

It can also make accommodations for people with wheelchairs, prams or pushchairs, who will need a little extra time.

The lights also have a system to report faults automatically, so pedestrians aren’t left stranded by the roadside if the camera fails. “This is a double safeguard,” says Possegger.

“The system was developed in such a way that it can work round-the-clock even in a harsh environment and can also deal with voltage fluctuations.”
