Navigation Apparatus and Route Guiding Method
First Claim
1. A navigation apparatus for transmitting information of a guiding route to a navigation terminal for performing route guidance of a moving object, characterized by including:
- communication means for performing communication with the navigation terminal;
map data storing means for storing map data;
route searching means for searching, using the map data, a guiding route between a departure place and a destination received from the navigation terminal through the communication means;
shape-simplified road map data generating means for generating, using the map data, shape-simplified road map data which includes at least the guiding route and a road intersecting the recommended route and in which a road shape of the guiding route is simplified;
notice part detecting means for detecting as a notice part a part of the guiding route having a difference greater than a predetermined quantity between a shape of the guiding route in the map data and the shape of the guiding route in the shape-simplified road map data;
guidance notice information generating means for generating, on the basis of the difference at the notice part between the map data and the shape-simplified road map data, guidance notice information to be supplied to the navigation terminal when the moving object reaches the notice part in the route guidance; and
information delivering means for transmitting delivery information including the shape-simplified road map data and the guidance notice information to the navigation terminal using the communication means.

Abstract
A navigation server 1, a map DB 102, a route searching part 104 for searching a guiding route between a departure place and a destination, a shape-simplified road map generating part 106 for generating shape-simplified road map data in which a road shape of the guiding route is simplified, a notice part detecting part 107 for detecting a part of the guiding route as a notice part having a difference grater than a predetermined quantity between the shape of the guiding route in the map data and a shape of the guiding route in the shape-simplified road map data, a notice information generating part 108 for generating, on the basis of the difference at the notice part between the guiding route in the map data and the shape-simplified road map data, a guidance notice information to be supplied to a navigation terminal 2 when a current place reaches the notice part, and a communicating part 110 for transmitting delivery information including the shape-simplified road map data and the guidance notice information are included. This improves a visibility of the guiding route and decrease error recognition of a guiding direction.
