Can ‘smart’ traffic lights ease Toronto’s road congestion?

But what if you could actually teach those stupid lights a lesson? Literally. What if you could significantly shorten the delays you face on those fitful rides to work? Baher Abdulhai, head of the University of Toronto’s Intelligent Transportation Centre, says he and his team can do just that. Abdulhai’s group has developed a system that would use small, artificial-intelligence-based computers to improve an intersection’s throughput efficiency as much as 60 per cent. “On average on (simulated) tests in downtown Toronto, we found reductions in queuing delays at intersections of about 40 per cent overall,” Abdulhai says.
