The route appropriateness value of the route is calculated on the basis of a cost of the route calculated by a cost calculation uniton the basis of a cost representing a degree of passage difficulty which is determined for each of the links with respect to a transportation means on the basis of accessibility information of the investigated link as well as a degree of passage uncertainty representing a possibility that the route cannot be passed through by the transportation mean which is calculated by a passage uncertainty degree calculation uniton the basis of a length of the uninvestigated link included in the route.
