Abstract
A ground apparatus system performs polling communication in which ground apparatuses are set as primary stations and trains are set as secondary stations. The ground apparatus stores a train list of train IDs of trains to be managed. The ground apparatus acquires, train information including train location information from the train to determine a train location of each train included in the train list. The ground apparatus calculates a coming-in allowable range of each train to generate traveling control information, and transmits the traveling control information to the train. The ground apparatus updates the train list by adding a train ID of a train that comes in a radio communication control region of the ground apparatus and deleting a train ID of a train that goes out from the radio communication control region by performing handover control of the trains to be managed with an adjacent ground apparatus.
