  • Publication number: 20230311965
    Abstract: 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 includes a timetable modification unit that modifies 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 staying passengers in each time zone at each station, by using demand information indicating a destination of a passenger in each time zone 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, and an output unit th

  • Patent number: 11754404
    Abstract: When input information including starting point information and destination information are input, this transport navigation system searches for a route for traveling from the starting point to the destination by a train of a transportation means on the basis of the input information, and outputs travel route information about the travel route obtained. The transport navigation system includes: a storage unit which stores the input information, an actual timetable including actual operation of the train, and a software program; and a CPU which executes the software program with reference to the input information and the actual timetable. The CPU calculates, on the basis of the actual timetable and the input information, the travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route, and generate travel route information on the basis of the travel route and the statistical amount.

  • Publication number: 20230281532
    Abstract: Provided is a service plan change assistance apparatus (110) including: a storage apparatus (13) that stores a decision model in which a service status of each of a delayed train and a to-be-delayed train to be delayed due to the delayed train and train service plan change content for recovering a delay of the to-be-delayed train are associated with each other, in association with a station at which the to-be-delayed train is delayed due to the delayed train; and an arithmetic apparatus (11) that estimates a future train service status based on a train service plan and a train service record before a current time, identifies, from the estimated train service status, the station at which the to-be-delayed train to be delayed due to the delayed train is standing, inputs information on the estimated train service status to a decision model associated with the identified station to create a service plan change proposal that includes information indicating train service change content for recovering the delay of t

  • Publication number: 20220358422
    Abstract: A timetable planning system 1 includes a storage device 13 and a computing device 11. The storage device 13 stores evaluation index improvement degree information 320 that stores relations between a change of each constituent element of an operation timetable on one hand and a change in quality of the operation timetable resulting from the change of each constituent element in terms of each operation timetable viewpoint on the other hand.

  • Publication number: 20220326026
    Abstract: The present invention assists at work related to the setting of an evaluation index for a vehicle operation plan. A vehicle operation assistance device manages one or more pieces of evaluation information including information regarding evaluation of the vehicle operation plan, acquires setting target information that is information regarding evaluation, the information being intended to be set for the vehicle operation plan by a user, derives a similarity degree between the setting target information and each pieces of the evaluation information, extracts evaluation information on the basis of the similarity degree, receives a setting for information regarding evaluation related to the vehicle operation plan from the user while presenting similar evaluation information which is the extracted evaluation information to the user and generates evaluation information on the basis of a received content.
