The invention relates to a method and device for generating, merging and updating data for use in a destination tracking system, which contains, among other, the following steps: Generation of data by mobile units (vehicles) representing real information of the road network and traffic conditions, and storage of said data. A highly up-to-date and extremely reliable database is made by merging data from many units in a simple and efficient way. This database makes it possible to answer a number of complex problems, for example, about the passable route network and realizable travel times. On input of an origin and destination node together with the intended travel time, destination tracking data is calculated from the stored data. Since the dependency of the origin-destination relationships on all conceivable parameters relating to the movements executed by the mobile units is known, the destination tracking recommendations for each individual participant can be given such that the sum of the travel times of all participants is minimised.
