Navigation apparatus, navigation method, and navigation program
First Claim
1. A travel history data correction apparatus, comprising:
- a memory that stores;
map data comprising connection relationships of links; and
vehicle travel history data for a plurality of the links along a vehicle travel route, each of the plurality of the links having a link number; and
a controller that;
detects adjacency relationships among the plurality of the links based on the map data; and
replaces a link having a link number indicating that there is no adjacency relationship for the link in the vehicle travel history data with another link having another link number indicating that there is an adjacency relationship for the other link.

Abstract
Navigation apparatus, methods, and programs merge and correct a plurality of types of past traffic information. The apparatus, methods, and programs may store a plurality of types of past traffic information, each type of past traffic information having a priority and may merge the stored past traffic information in accordance the priorities. The apparatus, methods, and programs may detect adjacency relationships among the plurality of links; and, if a detected link number indicates that the corresponding link is not adjacent to adjacent links, replaces the detected link number for the link, the replaced link number indicating that the link is adjacent to the adjacent links.

4. A travel history data correction apparatus, comprising:
-
a memory that stores; map data comprising connection relationships of links; and vehicle travel history data for a plurality of the links along a vehicle travel route, each of the plurality of the links having a link number; and a controller that; detects whether there is an adjacency relationship between a first link having a first link number and a second link having a second link number based on the map data, the second link number appearing directly after the first link number in the vehicle travel history data; detects whether there is an adjacency relationship between the first link and a third link having a third link number based on the map data, the third link number appearing directly after the second link number in the vehicle travel history data; and if there is no adjacency relationship detected between the first link and the second link and there is a an adjacency relationship detected between the first link and the third link, replaces the second link number with at least one of first link number and the third link number. - View Dependent Claims (5, 6)
