#CMT# #/CMT# The method involves determining two control points (K2, K3) provided between a start point (A) and an end point (C) at a line (6) that is parallel to a straight connection (3) between the start point and the end point, where the parallel line passes through a support point (B). A traffic route section is represented as a Bezier curve (7) from the start point to the end point, where the points are represented as two control points (K1, K4) of the curve, and the determined control points (K2, K3) are represented as other control points of the curve. #CMT# : #/CMT# An independent claim is also included for a device for representing a traffic route section in a map representation with a display device for the map representation. #CMT#USE : #/CMT# Method for representing a traffic route section in a map representation of an electronic device e.g. navigation system and route guidance system. Uses include but are not limited to a motor vehicle, a bicycle, a pedestrian, a ship and an airplane. #CMT#ADVANTAGE : #/CMT# The traffic route section is represented as the Bezier curve from the starting point to the end point, where the points are represented as two control points of the curve, and the determined control points are represented as the other control points of the Bezier curve, thus representing the traffic route section to a viewer in a naturally appealing manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a traffic route section of a representing method. A : Start point B : Support point C : End point K1-K4 : Control points 2 : Traffic route 3 : Straight connection 6 : Line 7 : Bezier curve. |
