A train crossing control database 12 that stores information on the surplus time used when calculating the start / end timing of the crossing that indicates the period during which the crossing 3 is cut off from the train crossing arrival time and the crossing crossing time, and train operation from the operation management system 2 The operation information acquisition unit 15 that acquires operation information including schedule information and train traveling result information that is a schedule, the crossing arrival time and crossing time of the train, and the allowance time are used to calculate the shutoff start / end timing, As a result of calculating the stop start / end timing of the current train, if the crossing stop time of the crossing 3 obtained from the start / stop timing of a plurality of trains is greater than the specified stop time threshold, the operation information of the first train that arrives first at the crossing 3 If it is judged that the arrival time at the next station is not delayed even if the arrival time at the railroad crossing is delayed for the first train It includes a timing calculation unit 14 for determining the speed reduction of the first-arrival train, the.
