Abstract

In a train control system, in position estimating methods by a tacho-generator, an acceleration sensor, and the like, since estimation accuracy always changes because of a train state, a surrounding environment, and the like, it is difficult to assume an appropriate error and set the error as the safety margin distance, an excess safety margin distance is set, and service density is deteriorated. On-board equipment 2 0 of a train 2 includes an on-board clock 22 that specifies track information and transmission time information from a GPS satellite la and reception time of the information, an on-rail range calculating section 23 that calculates an on-rail range according to the received information and the reception time, an on-board communication section 24 that performs transmission of own train on-rail range information to track-side equipment 30 and reception of stop target information from the track-side equipment 30, and a speed control section 25 that controls traveling speed of the own train on the basis of the stop target information. The track-side equipment 30 includes a stop target calculating section 32 that calculates stop targets according to on-rail range information of respective trains. The track-side equipment 30 transmits the stop target information to the trains to attain an optimum service with high safety and service density and energy saving.
