Abstract: A method for simplifying a description of a travel route represented by a list of route points includes: reading in a travel route which is mapped by a list of route points represented by a plurality of route points, each route point representing a different subsegment of a travel route on a digital road map; altering the list of route points according to a predetermined algorithm, in order to obtain an altered list of route points that represents the travel route; and storing the altered list of route points in order to simplify the description of the travel route.

Abstract: A method for the localization of a certain route section from a first digitized map in a second digitized map. An origin root point is established with regard to a route section in the first map, and the coordinates of this origin root point are determined. Starting from the origin root point, an origin tree structure is generated from a plurality of branches. A reference root point is established in the second map in the vicinity of the coordinates of the origin root point, and in a similar way, a reference tree structure is generated, starting from the reference root point, from a plurality of branches on which tree points are situated in such a way that they correspond in each case to a point of a traffic route in the second map.

Abstract: A method for the localization of a certain route section from a first digitized map of a traffic-route network in a second digitized map of the traffic-route network. In the method of this type, an origin root point is established with regard to a route section in the first map, and the coordinates of this origin root point are determined. Starting from the origin root point, an origin tree structure is generated from a plurality of branches, on which tree points are situated in such a way that they correspond in each case to a point in a traffic route in the first map. A reference root point is established in the second map in the vicinity of the coordinates of the origin root point, and in a similar way, a reference tree structure is generated, starting from the reference root point, from a plurality of branches on which tree points are situated in such a way that they correspond in each case to a point of a traffic route in the second map.
