AI is revolutionizing traffic lights—no more fixed timers. Researchers at Queensland University of Technology are testing smart systems that “see” real-time traffic (cars, bikes, pedestrians) and adjust signals on the fly. A major Australian first kicks off later this year in Petrie, with a $170K trial running until early 2029, aiming to slash wait times and turn reactive traffic control into proactive management. While some see it as a game-changer, experts like Professor Mohsen Ramezani caution that coordinating AI across busy city intersections is complex. The tech, already proven in Denmark and Pittsburgh (where travel times dropped 25%), is also set for a bigger Brisbane trial—$15 million over two years—to optimize entire road corridors. Could this be the future of smoother, smarter commutes?
