An implementation with means for controlling traffic signals at the intersection to permit vehicles in each of the intersecting traffic lanes a time period to pass through the intersection, means for detecting the presence of a vehicle in the intersection beyond said permitted time period, and means responsive to a detection of the presence of the vehicle, for controlling the traffic signals to stop other vehicles from passing through the intersection.
