Route guidance apparatus and method
First Claim
1. 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 route pattern of the route by referring to the road network data, and to obtain road pattern data as the analysis result;
a landmark selection area decision unit configured to determine a landmark selection area for route guidance along the route based on the road network data and the road pattern data;
a landmark selection unit configured to select landmark data included in the landmark selection area from said database;
a route guidance information generation unit configured to generate route guidance information of the route using the road pattern data and the landmark data selected by said landmark selection unit; and
a presentation unit configured to present the route guidance information.

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 the database. A road pattern analysis unit analyzes a route pattern of the route by referring to the road network data, and obtains road pattern data as the analysis result. A landmark selection area decision unit determines a landmark selection area for route guidance along the route based on the road network data and the road pattern data. A landmark selection unit selects landmark data included in the landmark selection area from said database. A route guidance information generation unit generates route guidance information of the route using the road pattern data and the landmark data selected by the landmark selection unit. A presentation unit presents the route guidance information.
