<p>A route search device comprises a storage section for storing map data including IC information, a specifying means for the user to specify a loading or unloading IC on the basis of the IC information on the ICs on toll roads included in a previously determined route on the map, and a judging means for, if the IC information includes use restriction information, judging whether or not a vehicle or the user is matched to the use restriction information, and a route search means for searching a route to the destination by using the IC information on the loading or unloading IC specified by the user. If the judging means judges that the vehicle or user is not matched to the use restriction information, the specifying means prevents the user from specifying the IC as the loading or unloading IC. If the judging means judges that the vehicle or user is matched to the use restriction information, the specifying means permits the user to specify the IC as the loading or unloading IC. This prevents the user from specifying an unavailable IC when the user specifies a loading or unloading IC, enabling smooth running.</p> |
