Navigation apparatus and navigation program

Abstract

If it is determined that a course change at a branch point is necessary and a vehicle is traveling on a road in which a lane is added to correspond to a road which is taken after the course change (road before the branch point), “direction guidance” is provided before a road section in which the lane is added (added lane section) and “lane guidance” is provided in the added lane section. As above, by switching the “direction guidance” and the “lane guidance” depending on whether the vehicle has reached the added lane section or not, and by providing either one of the guidances, a driver can recognize the guidance without confusion. Particularly, when the branch point is branched off at a narrow angle and when the added lane is a lane dedicated to the road which is taken after the course change, by providing the lane guidance, instead of the direction guidance indicating left or right, the guidance becomes easier to understand.

Dependencies are inferred from the claim text.
