Abstract
An on-board system increases a forward margin distance and a backward margin distance to expand an train occupancy range, when it is determined that position correction communications with a balise fail to be performed when a train passes through an installation position of the balise, that is, when it is determined that a detection failure has occurred. The expanded train occupancy range is restored to the train occupancy range before being expanded, when it is determined that the position correction communications have been successfully performed with a next balise, that is, when detection has been successfully performed.
