Abstract
A database stores map data including road network data and landmark data. A route search unit searches for a route from a departure point to a destination point from the road network data stored in said database. A road pattern analysis unit analyzes a road pattern of the route by referring to the road network data, and obtains road pattern data as the analysis result. A route guidance information generation unit generates route guidance information of the route using the road pattern data and the landmark data along the route. A presentation unit presents the route guidance information.
Claims22
A pedestrian route guidance apparatus, comprising:
- a database configured to store map data including road network data and landmark data;
- a route search unit configured to search for a route from a departure point to a destination point from the road network data stored in said database;
- a road pattern analysis unit configured to analyze a road pattern of the route by referring to the road network data, and to obtain road pattern data as the analysis result;
- a route guidance information generation unit configured to generate route guidance information of the route using the road pattern data and the landmark data along the route;
- and
- a presentation unit configured to present the route guidance information.
A pedestrian route guidance method, comprising:
- storing map data including road network data and landmark data in a database;
- searching for a route from a departure point to a destination point from the road network data stored in the database;
- analyzing a road pattern of the route by referring to the road network data;
