Abstract
An onboard system transmits a train occupancy range based on a measured train position to a ground system. The ground system provisionally detects the occupancy state of each block section based on the train occupancy range acquired from the onboard system. Exit detection points (Qh, Qr) are set at a position outside each block section. It is determined that the train has left the block section when the entirety of the train occupancy range has passed the exit detection point (Qh, Qr). When the provisional detection result indicates that the detection target block section is not occupied, and it has been determined that the train has left the detection target block section, it is determined that the detection target block section is not occupied.
