These AI Traffic Lights Could Shorten Your Commute

Your commute could get a lot shorter without you even knowing thanks to traffic lights with artificial intelligence brains inside. Over the past couple years, a startup named Surtrac has been mentally upgrading traffic lights in Pittsburgh with artificial intelligence. These lights collect data on the amount of traffic from cameras and radar signals, and the network of lights coordinates to ensure that all the traffic passes through intersections as fast as possible. The AI system began with nine intersections in Pittsburgh's East Liberty neighborhood in 2012 and has quietly expanded to 50 intersections. The startup plans to implement their network across the whole city.
