1. An intersection control system for controlling entries of vehicles into an intersection, the intersection control system comprising a central processing unit configured to:
acquire first vehicle information about a plurality of vehicles scheduled to pass through the intersection;
decide first intersection control information indicating permitted track information for the plurality of vehicles to pass through the intersection;
distribute the first intersection control information to the plurality of vehicles;
after a first predetermined time has elapsed, acquire third vehicle information about the plurality of vehicles;
decide third intersection control information indicating permitted track information for the plurality of vehicles to pass through the intersection;
determine whether the first intersection control information is different from the third intersection control information;
upon determination that the first intersection control information is different from the third intersection control information, decide second intersection control information based on the first intersection control information and the third intersection control information; and
distribute the second intersection control information to the plurality of vehicles, thereby causing an autonomous vehicle of the plurality of vehicles to enter the intersection or wait before entering the intersection based on the second intersection control information.
