DRIVING OPERATION DETERMINATION TABLE DATA CREATION UNIT, TRAIN OPERATION ASSISTANCE SYSTEM, AND TRAIN OPERATION ASSISTANCE METHOD

A train operation support device (driving operation determination table data creation unit 11) provides driving operation determination table data information 119 which constitutes one of predetermined input information and provides a determination criterion of a driving operation, to a train system that determines the driving operation of a train based on the predetermined input information. The driving operation determination table data creation unit 11 includes an overall table creation unit 115 that creates overall table information 116 according to table information related to an entire target section on which the train travels, and a table region limiting unit 118 that limits, from the overall table information 116, table information of a region where switching of the driving operation is performed within the fluctuation range of the external factor that affects traveling of the train, and outputs the limited table information as the driving operation determination table data information 119.
