PROBLEM TO BE SOLVED: To provide a navigation system and a navigation method for searching an optimum passing route to a walking user or a user on a bicycle. SOLUTION: A current position detection section 26 processes a signal received from a GPS satellite 19 via a GPS antenna 20, and detects the current position of a user passing on foot or by a bicycle. Map data near the current position and weather data near the current position are transmitted to a portable terminal 10 from a map data server 32 and a weather data server 34, respectively, via a communication section 24. A passing route searching circuit 41 searches an optimum passing route, based on the received weather data for displaying on an LCD 12. COPYRIGHT: (C)2005,JPO&NCIPI |
