1. An information management system comprising:
a first storage unit configured to store road information in which first information acquired by a first sensor and indicating that there is no stationary object on a road and second information acquired by a second sensor and indicating that there is a stationary object on the road are associated with each other;
a second storage unit configured to store, for each type of moving objects configured to move on the road, passage possibility information related to possibility of passage on the road; and
a determination unit configured to determine, for each of the types of moving objects, whether the road is usable for passage based on the road information and the passage possibility information,
wherein the road information is information including a plurality of grids,
wherein the passage possibility information includes unique information indicating a specification unique to each of the types,
wherein the unique information includes information relating to one or more countermeasure functions each of which enables traffic to deal with a stationary object on the road according to each of the types of stationary objects, even if there is a stationary object on a road,
wherein the determination unit executes:
first processing which is to determine, for each of the types of moving objects, whether a moving body of each of the types passes through a grid corresponding to the second information based on the unique information, and
second processing which is to convert a grid determined to be impassable in the first processing into a lane based on lane information that is used for searching for a route and identifying each of lanes corresponding to the grids, and
wherein in the first processing, when the unique information indicates that a certain type of moving body has the countermeasure function corresponding to each of the types of stationary object in the grid to be determined, the determination unit determines that each of the types of moving body can pass through the grid.
