Claims

1 . A train operation support system for outputting a rescheduled timetable for a planned timetable of a train from a computer by using the planned timetable and an actual timetable of the train, the train operation support system comprising:a timetable modification unit that modifies, upon receiving new transport disorder information, the planned timetable by using a given timetable modification method;a passenger flow prediction unit that calculates passenger staying information containing information indicating the number of passengers in each time slot staying at each station, by using demand information indicating an expected destination of each passenger in each time slot at each station where the train stops;a timetable rescheduling unit that modifies the demand information in reference to the planned timetable modified by the timetable modification unit, inputs the modified demand information to the passenger flow prediction unit, and creates the rescheduled timetable for the planned timetable by using the passenger staying information output from the passenger flow prediction unit; and2025201234   21 Feb 2025timetable created by the timetable rescheduling unit based on the planned timetable modified by the timetable modification unit to a traffic management system to be used for controlling a plurality of trains, wherein the traffic management system causes the plurality of trains to operate in accordance with the rescheduled timetable;wherein the train operation support system further comprises :a storage unit that stores a plurality of passenger models indicating how each passenger changes his or her travel behavior according to traffic conditions, each of the passenger models including information representing a pair of transfer stations and a detour time associated with a combination of a suspended section and a waiting time for each passenger, wherein the timetable rescheduling unit modifies the demand information by identifying, from the plurality of passenger models, a relevant passenger model that has the suspended section and the waiting time consistent with a corresponding suspended section and a corresponding waiting time associated with the planned timetable modified by the timetable modification unit, and updating the demand information based on the suspended section, the pair of transfer stations and the detour time of the relevant passenger model.2025201234   21 Feb 20252 . The train operation support system according to claim 1, further comprising:a storage unit that stores a statistic containing information indicating a probability associated with a travel behavior selected by the passenger for traffic conditions of the train, whereinthe timetable rescheduling unit modifies the demand information by using the planned timetable modified by the timetable modification unit and the statistic.

3. The train operation support system according to claim 1, wherein the timetable rescheduling unit estimates, by using the passenger staying information output from the passenger flow prediction unit, a staying amount containing either one of or both the number of passengers indicating the number of passengers in each time slot staying at each station and density indicating a level of congestion of passengers staying in each time slot at each station, for the planned timetable modified by the timetable modification unit, calculates an evaluation value associated with the staying amount, and creates the rescheduled timetable for the planned timetable by usingthe evaluation value.2025201234   21 Feb 20254. The train operation support system according to claim 3, wherein the timetable rescheduling unit calculates the evaluation value associated with the staying amount by using a weighted value set for each station, or calculates the evaluation value associated with the staying amount by using either one of or both the staying amount larger than a predetermined threshold and the staying amount smaller than the predetermined threshold.

5. The train operation support system according to claim 3, further comprising:a storage unit that stores either one of or both passenger flow information containing information indicating the staying amount for the rescheduled timetable and timetable modification log information containing information indicating modification practiced at the time of creation of the rescheduled timetable, whereineither one of or both the passenger flow information and the timetable modification log information is output together with the rescheduled timetable.

6. The train operation support system according to claim 1, whereinthe passenger flow prediction unit further calculates passenger riding information containing2025201234   21 Feb 2025information indicating the number of riding passengers at the time of departure of each train from each station, and the timetable rescheduling unit creates the rescheduled timetable for the planned timetable by using the passenger staying information and the passenger riding information output from the passenger flow prediction unit.7 . A train operation support method performed by a computer to output a rescheduled timetable for a planned timetable of a train by using the planned timetable and an actual timetable of the train, the train operation support method comprising:a process of modifying, by a train operation support system upon receiving new transport disorder information, the planned timetable in reference to a given timetable modification method;a process of modifying, in reference to the modified planned timetable, demand information indicating an expected destination of each passenger in each time slot at each station where the train stops;a process of calculating passenger staying information containing information indicating the number of passengers in each time slot staying at each station by using the modified demand information;a process of creating a rescheduled timetable for2025201234   21 Feb 2025the planned timetable by using the calculated passenger staying information; anda process of outputting the rescheduled timetable created based on the modified planned timetable to a traffic management system to be used for controlling a plurality of trains, wherein the traffic management system causes the plurality of trains to operate in accordance with the rescheduled timetable;wherein the train operation support method further comprises :a process of storing a plurality of passenger models indicating how each passenger changes his or her travel behavior according to traffic conditions, each of the passenger models including information representing a pair of transfer stations and a detour time associated with a combination of a suspended section and a waiting time for each passenger, wherein the process of creating the rescheduled timetable includes modifying the demand information by identifying, from the plurality of passenger models, a relevant passenger model that has the suspended section and the waiting time consistent with a corresponding suspended section and a corresponding waiting time associated with the modified planned timetable, and updating the demand information based on the suspended section, the pair of2025201234   21 Feb 2025transfer stations and the detour time of the relevant passenger model.
