METHOD AND APPARATUS FOR CONVERTING FROM AN ANALYTICAL CURVE ROAD GEOMETRY TO A CLOTHOID ROAD GEOMETRY

摘要

A method, apparatus and computer program product are provided in order to convert a representation of a road geometry in the form of an analytical curve to a clothoid road geometry. In the context of a method, a plurality of break-point locations are determined along an analytical curve that represents a portion of the road network. The method determines the plurality of break-points locations by determining the plurality of break-point locations depending upon a curvature profile of the analytical curve so as to define one more sections of the analytical curve based upon the break-point locations. The method also converts one of more sections of the analytical curve to respective clothoids.
