PURPOSE: A load distributing method of a vehicle driving information collecting server by using location information of a vehicle is provided to connect vehicles located in the same geographic region to the same collection server, thereby significantly reducing system load. CONSTITUTION: A vehicle terminal installed in a vehicle transmits location information of the vehicle to a distribution server and requests assignment of a collection server (S10). The distribution server determines a collection server in charge of a geographic region which the vehicle belongs to by referring to a regional collection server classification policy database storing collection servers in charge of each geographic region, and transmits the connection address of the collection server to the vehicle terminal (S20). The vehicle terminal transmits vehicle driving information to the collection server (S30).
