Abstract

See full text

With respect to each of trains, a ground device 6 detects a train location in the control section on the basis of a propagation time of a radio wave between a vehicle radio set 4 and a wayside radio set 5, in the case in which the ground device 6 determines that the number of trains has reached the controllable number of trains or there is the possibility that the number of trains reaches the controllable number of trains in its own control section, a ground device 6 disposed in an adjacent control section to the control section in which the number of trains is reaching the controllable number of trains, when a train 2 scheduled to travel toward the control section stops in a station 8, prevents departure of the train 2 scheduled to pass through the border of the control section by making the train 2 wait at the station 8.
