The route calculation server receives starting point data and destination data corresponding to a starting point and a destination which a user designates by the user terminal, and calculates a route from the starting point to the destination. The map server includes a map database, and communicates with the user terminal via the network. The route calculation server stores calculated route data together with route identification information associated with the route data, and transmits the route identification information to the user terminal via the network. The map server receives the route identification information from the user terminal via the network, obtains the route data associated with the route identification information from the route calculation server, produces route display picture data including map picture on which the calculated route is represented, and transmits the route display picture data to the user terminal.
