Abstract:
1. An estimated train occupancy range determination device that determines an estimated train occupancy range in which a train may be present, the train including a measurement section that measures a train position, a correction coil communication section that communicates with a correction coil when the train passes through an installation point of the correction coil, and a correction section that corrects the train position based on a communication result of the correction coil communication section, the estimated train occupancy range determination device comprising: a processor that is configured to: detect whether or not the train position has been corrected to a position in a backward direction relative to a train traveling direction; and determine the estimated train occupancy range using the train position, the processor maintaining the estimated train occupancy range when the processor has detected that the train position has been corrected to the corrected position until a latest train position reaches the train position immediately before the train position is corrected to the corrected position.
