Description

This invention relates to a train schedule creation device, a train schedule creation system, and a train schedule creation method. In rail transport services, operational planning is used to manage train departure and arrival times within the rail network, taking into account operating costs and demand. Traditionally, operational planning has been done manually by rail operators, considering the infrastructure of the rail network and passenger needs. In order to generate reliable operational plans, it is crucial to accurately predict the demand for railway services and the movement of passengers (where they are going and where they are going). For example, one method for creating a timetable that represents train control targets based on forecasts of travel demand is described in Japanese Patent Publication No. 2019-73146 (Patent Document 1). Patent Document 1 describes a "target timetable creation device 100 that modifies a timetable representing train control targets according to travel demand forecast results showing the destinations and number of passengers at each station where the train stops, for each time period. This device includes a violation location extraction program P01a that calculates the degree of train congestion based on forecast demand information representing the travel demand forecast results and extracts violation locations where the congestion degree falls outside a predetermined acceptable range, and a timetable modification program P01b that modifies the timetable, including changing the train's destination, so that the congestion degree at the violation locations falls within the acceptable range, or approaches the acceptable range."
