August 6 is 100th anniversary of the traffic light at an intersection in Cleveland, Ohio. Today, traffic lights are controlled by sensors that include proximity sensors with some intelligent sensors using localized software. In the future, traffic lights may make driving safer, reduce commutes, save time and lower emissions.
Researchers at MIT have developed a means of computing optimal timings for city stoplights that can significantly reduce drivers’ average travel times. The software adjusts signal times at intersections distributed across the entire city, with the objective of trying to improve conditions across the entire city, while present systems are timed to local information
