IPC: G01C21/00
Filed: 2002-02-08
Abstract: PROBLEM TO BE SOLVED: To solve the problems that a map screen of a monitor performs a display as if traveling an elevated express way to make a user feel a sense of incongruity when traveling an ordinary road present below or adjacent to the elevated expressway and that the user feels uneasiness about an unknown destination of the ordinary road when the ordinary road under the viaduct is not seen. SOLUTION: In this navigation apparatus in one mode, a part 36 for detecting traveling in proximity to an elevated road detects that a motor vehicle is traveling the ordinary road below the elevated road or traveling the ordinary road adjacent to the elevated road. Then a part 37 for altering the display of the elevated road before and after the location of one's own motor vehicle alters a display color of the elevated road within a predetermined range before and after one's own motor vehicle into the same display color as that of an ordinary road or into another display color, and displays it. By this, it is possible for the user to distinguish that the user is not traveling the elevated road at a glance. In another mode, the ordinary road under the viaduct in proximity to the motor vehicle is made translucent, etc., so that both roads are seen.
