ABSTRACT:
Systems, methods, and programs of producing and using traffic signal information take, when a vehicle is closely approaching a traffic signal, an image of traffic signal lamps disposed on the traffic signal. The systems, methods, and programs produce image data of the traffic signal lamps, based on the taken image and analyze the image data. The systems, methods, and programs produce traffic signal state information, the traffic signal state information including a state of the traffic signal as of the time of taking the image of the traffic signal lamps. The systems, methods, and programs store traffic signal information, the traffic signal information including the produced traffic signal state information, traffic signal location information, and time information in a memory.
