IBM has recently filed a patent application for a new traffic light system that can remotely start and stop the engines of our vehicles. According to this patent application traffic light system would receive position data from all vehicles waiting at traffic lights and would then send a stop engine notification to all the vehicles waiting for more than a specified period of time. After that when the light turn green a start engine notification would be sent to the front vehicle to start its engine first and another signal would be sent to next vehicle in the waiting row an optimal time later and so on.
This new traffic light system would be very helpful to reduce wastage of fuel. According to IBM this new traffic light system could be applied to traffic signals at railway crossings, intersections or other transportation signals.
