Abstract (en)
[origin: WO2009143826A1] The invention relates to a method for the geographical positioning (5) of a passenger in relation to a road element (3, 4) on a digital road map. The invention further relates to a corresponding computer program product and to a digital memory medium and to a corresponding navigation device. The invention is characterized in that a virtual corridor (6) is defined along a road element (3) that is associated with the actual position (5), movement components of the passenger at a right angle to the road vector of the actual road element (6) and/or information on the momentary direction of the passenger being ignored inside the corridor (6) during map matching, i.e. examination of the actual position of the passenger by means of map data. The invention allows the accuracy of positioning by means of GPS to be increased especially in the case of passenger navigation. The proneness to errors of known navigation methods and devices with respect to the movements of a passenger at a right angle to the road direction can be considerably reduced, especially for navigation applications in town centers.
