PROBLEM TO BE SOLVED: To achieve a system in consideration of upbound and downbound trains on a single-track line.;SOLUTION: At a station where single-track lines cross each other, when the arrival of a train 30a at a predetermined position in the area is detected, the blockage of an in-area blocked section A2 at the arrival position is temporarily cancelled. The temporary cancellation means a blocking state which is considered to secure blockage in the same direction and to cancel blockage in the opposite direction. Thus, a train 30b in the opposite direction (downbound direction), which is on rail at the same station, can secure the blockage of the next blocked section (inter-station blocked section) B1 although the next blocked section B1 competes against the in-area blocked section A2 in the opposite direction.;COPYRIGHT: (C)2013,JPO&INPIT
