Timetable Creation Apparatus, Timetable Creation Method, and Automatic Train Control System

A timetable creation apparatus for correcting a target timetable being a timetable to be used to control a group of vehicles by using a predicted passenger demand to thereby create a new target timetable, comprising:

• an objective function generation unit that generates an objective function for an operation headway between vehicles included in the group of vehicles by using the predicted passenger demand;
• a constraint condition generation unit that derives constraint conditions which an arrival time and a departure time of each of the vehicles at each of stations should satisfy for operation of the group of vehicles to be operable;
• and
• a candidate timetable creation unit that creates a candidate timetable as a candidate for a target timetable by using an optimum value of an arrival time and an optimum value of a departure time of each of the vehicles at each of the stations derived by optimizing the objective function under the constraint conditions,
• wherein the timetable creation apparatus outputs the candidate timetable created by the candidate timetable creation unit as a new target timetable.

An automatic vehicle control system comprising:

• a timetable creation apparatus which includes
• an objective function generation unit that generates an objective function for an operation headway between vehicles included in a group of vehicles being control targets by using a predicted passenger demand calculated based on information obtained from a predetermined sensor,
• a constraint condition generation unit that derives constraint conditions which an arrival time and a departure time of each of the vehicles at each of stations should satisfy for operation of the group of vehicles to be operable, and
• a candidate timetable creation unit that creates a candidate timetable as a candidate for a target timetable being a timetable to be used to control the group of vehicles, by using an optimum value of an arrival time and an optimum value of a departure time of each of the vehicles at each of the stations derived by optimizing the objective function under the constraint conditions, and
• which outputs the candidate timetable created based on a latest target timetable by the candidate timetable creation unit as a new target timetable;
• and
• a traffic management system which controls each of the vehicles based on the output target timetable.

A timetable creation method of correcting a target timetable being a timetable to be used to control a group of vehicles by using a predicted passenger demand to thereby create a new target timetable, comprising causing a timetable creation apparatus to execute:

• an objective function generation process of generating an objective function for an operation headway between vehicles included in the group of vehicles by using the predicted passenger demand;
• a constraint condition generation process of deriving constraint conditions which an arrival time and a departure time of each of the vehicles at each of stations should satisfy for operation of the group of vehicles to be operable;
• and
• a candidate timetable creation process of creating a candidate timetable as a candidate for a target timetable by using an optimum value of an arrival time and an optimum value of a departure time of each of the vehicles at each of the stations derived by optimizing the objective function under the constraint conditions, and
• to output the candidate timetable created by the candidate timetable creation process as a new target timetable.
