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 the planned timetable by using a given timetable modification method;
a passenger flow prediction unit that calculates passenger staying information containing information indicating a 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;
an output unit that outputs the rescheduled timetable created by the timetable rescheduling unit; and
a display screen that displays the output of the rescheduled timetable including line segments representing running of trains among the each station, each of the line segments indicating running of the trains being colored according to a number of riding passengers of a corresponding train, and a horizontal axis, representing a position of the each station, being colored according to the number of staying passengers in the each time zone at the each station.
