PROBLEM TO BE SOLVED: To easily grasp a time range in which a traveling object should not enter a predetermined place L in the case of adjusting the traveling speed or traveling direction of the traveling object traveling to the predetermined place L.SOLUTION: A prediction part 131 of a screen output system 100 predicts, when a traveling object travels on a route from a position where it is present at the current time to a predetermined place L, a time when the traveling object arrives at the predetermined place L. A calculation part 133 of the screen output system 100 calculates a position range in which it is assumed that the traveling object is present at the current time such that a time range in which it is predicted that the traveling object arrives at the predetermined place L by the prediction part 131 when the traveling object travels from the position where it is assumed that the traveling object is present at the current time is coincident with a scheduled time range in which the entry of the traveling object to the predetermined place L is restricted. A generation part 134 of the screen output system 100 generates a screen on which the position range calculated by the calculation part 133 is displayed on the route, and outputs it to an output device. |
