Document Type and Number:
WIPO Patent Application WO/2016/132758
Kind Code:
A1
Abstract:
In order to prevent interference between manned vehicles and unmanned vehicles with a simple operation and without causing a reduction in work efficiency, this traffic management system includes a dump truck terminal device 26 in an unmanned vehicle 20 that travels autonomously in a mine, a traffic management server 31, and a manned vehicle terminal device 76 mounted in a manned vehicle 70, with the vehicles and the server communicably connected to each other. The traffic management server 31 is equipped with a travel permission granting unit 311f that grants travel permission to the unmanned vehicle 20, and an interference control unit 311d that sets work area data to a closed state in which entry by the unmanned vehicle 20 into a residence work area within the mine in which the manned vehicle 70 is permitted to travel or work is prohibited or an open state in which entry is permitted, said work area data indicating the state of the residence work area. When a closing request signal is received from the manned vehicle terminal device 76 and the unmanned vehicle 20 is outside of the residence work area, the work area data is set to the closed state, and when an opening request signal is received and the manned vehicle 76 is outside of the residence work area, the work area data is set to the open state. During the closed state the travel permission granting unit 311f does not grant travel permission within the residence work area. The travel permission granting unit grants travel permission within the residence work area only during the open state.
