Method for segmenting and computing the pattern of a road
First Claim
1. A method for subdividing a road pattern in digital road maps into segments, the method comprising:
- using a navigation system to perform the following steps;
starting from digital road maps in which the road pattern is subdivided into successive segments,establishing new segment borders via new segment starting points and segment end points by selecting the segment starting points and the segment end points in such a way that the shape of the segments between the segment starting points and the segment end points does not change.

Abstract
The present invention relates to a method for subdividing the road pattern in digital road maps into segments, in which, starting from the digital road maps in which the road pattern is subdivided into successive segments, new segment borders are established via new segment starting points and segment end points, by selecting the segment starting points and the segment end points in such a way that the shape of the segments between the segment starting points and the segment end points does not change. The invention also relates to the computation of the road pattern with the aid of digital road maps, in which the road is subdivided into successive segments, to each of which one segment starting point and one segment end point is assigned. The shape of the segment is established and, from its relative position, its pattern is computed with the aid of the number of support points situated between the segment starting points and the segment end points, and/or with the aid of transition conditions between the segments and/or the consideration of attributes.
