Patent attributes
A traffic control system for a manned vehicle, traveling on one of plural lanes arranged side by side in a mine, and a traffic control device connected with the vehicle. A zone of the lane, on which the vehicle is traveling, is set as a first travel-permitted zone with a travel permission given to the vehicle only. Upon receipt of a request from the vehicle for a travel-permitted zone of another-lane with a travel permission given only to the vehicle on a lane adjacent the lane on which the vehicle is traveling, the traffic control device sets, as the travel-permitted zone of the another-lane, a zone including at least a part of a zone arranged on the adjacent lane side by side with the first travel-permitted zone, and transmits the travel-permitted zone of the another-lane to the vehicle, which the vehicle displays on a display screen.
