PROBLEM TO BE SOLVED: To provide a movable body-database concert system making it easy for respective movable bodies to share latest map data with each other on a high real time basis. SOLUTION: In this movable body database concert system 50, an area is divided into a plurality of mesh domains R<SB>1</SB>to R<SB>9</SB>to store a map database in a map data server device 30, with the database made by mapping already-existing map data for each of the mesh domains, and prescribed map data corresponding to an acquisition request Ra are transmitted from a map information accumulation management device to the movable bodies, with the acquisition request Ra transmitted from the movable body carrying or being equipped with a communication apparatus. In structuring this concert system 50, a plurality of movable bodies positioned in the same mesh domain are formed into groups S<SB>1</SB>to S<SB>7</SB>to select one movable body having a representation right for each of the groups. Only the movable body having the representation right transmits the acquisition request to the management device to receive prescribed map data Dm, and then, the movable body having the representation right delivers information including the map data to the other movable bodies within the group.
