In methods for encoding and decoding objects with reference to a traffic route network, wherein the encoded information can also be decoded with the aid of databases that differ from a database used in the encoding, the objects are provided with relationships to at least one relational object which is present in databases that are used for the decoding, and the relationships do not primarily result from the traffic route network. A position indication can also be provided with a position type designator, which for instance indicates whether the transmitted position is an exact or navigable position or is the location of a search space.

Method for encoding and decoding objects with reference to a road network

A method for manipulating source data to determine a route from a predetermined starting point to a predetermined destination for a means of conveyance, in particular for a motor vehicle, airplane or ship, based on a digital database that includes predetermined route segments k with correspondingly assigned nodes n that interconnect respective route segments k , where respective weights g are assigned to the route segments k and/or the nodes n . The weights g are varied, as a function of external events, before a route finding algorithm determines the route.

Method for influencing source data for determining a route in a navigation system

A method for requesting and for processing traffic information, in which a traffic-information query is transmitted by a mobile transceiver, and at least one traffic message is provided by a service provider via a base station, the traffic message being transmitted as a brief coded message. Information about the version of the stored data or data groups in the memory allocated to the mobile transceiver, and/or the manufacturer of the stored data or data groups and/or the issue date of the stored data or data groups is transmitted to the base station in the traffic-information query, so that in the return message of the traffic information, the base station can undertake the coding in such a way that the coded data can be well utilized on the basis of the stored data in the vehicle. In this manner, even given changing data, it is ensured in all events that the mobile transceiver is able to interpret the coded traffic messages.
