AI Technical Summary
Technical Problem
Existing systems face increased calculation load when deriving movement plans for moving objects due to the need to consider behavior such as acceleration, which is exacerbated by shortening time intervals.
Method used
A control method and system that sets unit times so that travel times divided by this unit time result in approximately integer values, allowing for accurate calculation and reducing computational load by ensuring the unit time does not become unnecessarily small.
Benefits of technology
This approach reduces calculation load by setting optimal unit times, enabling accurate travel planning for moving objects within areas defined by multiple sections.

Abstract
This control method comprises: calculating each of the travel times required for a moving body 13 to travel between adjacent sections, on the basis of a plurality of travel relationship values relating to the moving body 13; setting a unit time such that all of the values obtained by dividing each of a plurality of required travel times by the unit time are approximate integer values; and deriving a travel plan for the moving body 13 so that the moving body 13 is located in one of the sections every unit time.
