1. An information display system comprising:
a status determination device located outside a plurality of vehicles, the status determination device being configured to acquire a distribution status based on a detection result of positions of a plurality of objects to be avoided in a target area, the plurality of objects including one or more obstacles, one or more vehicles, one or more persons, one or more groups of persons, or one or more combinations thereof, the distribution status of the plurality of objects capable of varying based on movement of the objects in the target area;
a route generation device located outside the plurality of vehicles, the route generation device being configured to determine a gap between the plurality of objects through which a vehicle is capable of passing based on the distribution status of the plurality of objects as acquired for each of the vehicles, the route generation device further configured to generate a scheduled route on which the vehicle is capable of traveling based on the gap between the plurality of objects as determined for each of the vehicles so as to avoid interference between the vehicles and/or the objects;
a device located outside the plurality of vehicles, the device being configured to display scheduled routes of the vehicles on a floor of the target area, wherein in a case where the status determination device detects that a person has entered the scheduled route and the route generation device detects that the scheduled route as displayed has been violated, the device displays a warning at a position on the floor corresponding to a current position of the person who has entered the scheduled route; and
wherein the device is a display forming a part of the floor of the target area and the route generation device is further configured to transmit data indicating the scheduled routes to the device in the target area based on generated scheduled routes.
