Method for determining itinerary data
First Claim
1. A method for determining travel route data using a digital map which is kept in a central control station comprising the steps of:
- measuring dynamic parameters for traffic routes;
storing static and the dynamic parameters in the digital map by route section for detected traffic routes, the static parameters including at least structural features of a respective traffic route, the dynamic parameters including at least one conductance value representing traffic flow and one load function representing capacity of a respective section of the traffic route;
deriving the dynamic parameters one time for presetting starting values from the structural features and, from that point, continuously adapting the dynamic parameters to real conditions of the respective sections of the traffic route with ensured availability of dynamic data independent from static parameters; and
determining the travel route data based on relevant ones of the dynamic parameters.

Abstract
A method for determing travel route data, especially within the framework of navigation of a vehicle, using a digital map which is kept in a central control station and in which static and dynamic parameters are stored by route section for the detected traffic routes, wherein the static parameters include at least structural features of the respective traffic route. The dynamic parameters include at least one conductance value and one load function of the respective section of the traffic route. The dynamic parameters are derived one time for the presetting of starting values from the structural features and, from that point, are continuously adapted to the real conditions of the respective sections of the traffic route with ensured availability of dynamic data independent from static parameters. The travel route data are determined on the basis of the relevant dynamic parameters.
