NAVIGATION SYSTEM

PROBLEM TO BE SOLVED: To provide a navigation system capable of providing information of facility including features seen from the relation between the facility and region even in the case, a user visited unknown place. SOLUTION: A CPU 41 of a navigation system 2 transmits the intrinsic information including facility identification data and the user identification data to an information delivery center 3 (S11 to S15), when determined that parking was longer than prescribed time. A CPU 11 of an information delivery center 3 determines whether the vehicle is local vehicle or not, based on the received intrinsic information. The CPU 11 calculates the local vehicle recommendation rate (S111 to S115) which is the rate of total parking number of local vehicle and general vehicle to the parking number of local vehicle parked in the facility. The CPU 11 calculates a local obsessive index which is the ratio of the parking number of the local vehicles to the parking number of local obsessive vehicles (S116). COPYRIGHT: (C)2007,JPO&INPIT
