To provide the criteria of a necessary time, etc., until a requested vehicle arrives at the waiting place of a user when the user requests dispatching of the vehicle such as a taxi.

ASP 4 receives the position information of the taxi 3 transmitted from the taxi 3. When the user desiring to request dispatching of the taxi 3 performs dial up connection to the ASP 4 by using a portable terminal 1, an exchange 7A transmits the positional information of a portable terminal 1 as the present position of the user to the ASP 4. The ASP 4 retrieves a map DB 15 based on the positional information of this user to fetch map data of the periphery of the user. When the position of an empty taxi is included on this periphery map, display data expressing the user is added to the present position of the user on the map and display data expressing the taxi is added to the present position of the empty taxi 3 to be transmitted to the portable terminal 1 with the periphery map to be displayed.
