A New AI Traffic Light Could Help Shorten Your Commute Times

A new study out of Germany says having traffic lights use AI technology may keep traffic flowing faster and smoother. Jalopnik reports: One of the partners in the study with an aggressively German name -- the Fraunhofer Institute for Optronics, System Technologies and Image Exploitation -- recently installed high-resolution cameras and radar sensors at a busy intersection with a traffic light in the city of Lemgo, according to New Atlas. The setup recorded the number of vehicles waiting for the light to change, the amount of time each of them had to wait and the average speed a vehicle drove through the intersection. Science wizardry was then used to train a machine-learning based computer algorithm. It experimented with different light-changing patterns. They would continuously adapt to real time traffic conditions and see which ones worked best to keep wait times down. According to the simulations, the best artificial intelligence patterns could improve traffic flow by 10 to 15 percent. That may not sound like a ton, but add up all the time you spend white-knuckled at a long traffic light, and chop 15 percent off. Not too bad. The algorithm will be used to run the traffic lights at actual intersections in Germany for the next few months, and can only get better. The study is also looking to find ways to reduce waiting times at crosswalks for pedestrians. They're using LiDAR sensors among other things to assess the walking speed of pedestrians to make sure they have enough time to cross before the light turns on them.
