Abstract
A method and an apparatus for guidance of a road condition for providing prospective information concerning a configuration of a forthcoming curve or intersection on a traveling route for ensuring safe driving, particularly in the dark or roads such as winding roads, mountainous roads and so forth. The apparatus includes a detecting circuit for detecting a traveling link among a plurality of links in road information on which a vehicle is traveling; a circuit for detecting an instantaneous position of the vehicle and a traveling direction of the vehicle; and a circuit for calculating a distance from the instantaneous vehicle position to a forthcoming end of the traveling link on the basis of the instantaneous vehicle position and the traveling direction. In addition, the apparatus includes a circuit for detecting a number of intersecting links connected to the forthcoming end of the traveling link; a circuit for calculating an intersecting angle at the forthcoming end of the traveling link with the intersecting links, and a circuit for displaying information concerning curvature at the intersection of the links.
