摘要： PURPOSE:To shorten the time required for going-in and going-out, and to efficiently execute a running test for an unmanned vehicle, by stopping temporarily an unmanned automatic vehicle at a scheduled interval at the time of going-in and going-out. CONSTITUTION:A running path 1 is divided into section of A1-An, a siding course 2 is divided into sections of P1-Pn, and by an operation controller 5, a block control and a speed control are executed. In case of a going-in operation, an unmanned automatic vehicle which is running is stopped temporarily at a scheduled interval, a loop switching device 3 is switched to the Pn side, and a vehicle for which it is desired to go in from the section Pn-2 is allowed to go in and stopped at the section A3. Thereafter, the device 3 is returned to its original state, and all the cars are started simultaneously. On the other hand, in case of a going-out operation, the vehicle which is running is stopped temporarily and a loop switching device 4 is switched to the P1 side, and a vehicle whose shunting is desired is stopped at Pn-2. Thereafter, the device 4 is returned to its original state again and all the cars are started simultaneously.

摘要： PURPOSE:To prevent the unmanned self-propelled vehicle from running away in a section wherein an ATC limit high-speed signal is not outputted by provid ing the section at an intermediate part of one ATC loop for the transmission of the ATC limit high-speed signal. CONSTITUTION:A travel path is divided into many sections, ATC loops 6 which transmit ATC limit high-speed signals are provided for the respective sections, and one ATC loop 7 is twisted at part of a stand-by course 2. The same limit speed is outputted at the parts of both end sides where the ATC loop is not twisted, but at the part 9 where the ATC loop is twisted, outputs cancel each other with the induced electromotive forces of mutual loops and no ATC limit high-speed signal is outputted. Consequently, the unmanned free-running vehicle entering this part is disabled to receive the ATC limit high-speed signal and stops so even if an ATC ground device malfunctions, the unmanned self-propelled vehicle is stopped without fail.

摘要： PURPOSE:To obtain an inexpensive system by receiving a signal, which shows a destination, from a bus to a guiding and displaying device on the ground and executing the broadcast and display, etc., of guidance to passengers waiting for the bus. CONSTITUTION:When a bus 1 approaches in the measure of 100m before the bus stop, a reception antenna 11 and a ground receiver 9 of a guiding and displaying device 7 to be set in the bus stop on the ground receive the signal showing a route number from the bus and it in inputted to a controller 8 which route bus 1 approaches. The controller 8 checks whether the inputted route number is a route number corresponding to the controller 8 itself or not. When it is judged that the bus 1 of the route approaches, a command is outputted to a guidance broadcasting and displaying device so that the prescribed guidance can be broadcasted and displayed. The guidance broadcasting and displaying device executes the broadcast and display of the guidance based on the command of the controller 8 and executes the service guidance to the passengers waiting for the bus. Thus, the cost of equipment and construction can be reduced.
