A method and device for generating, merging and updating data for use in a destination tracking system which comprises, among others, the following steps: Generation of data by mobile units (vehicles) to model reality concerning route(s) and traffic, and storing this data for further use. A highly up-to-date and extremely reliable database is built-up in a simple and efficient way by merging data from many units. 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 a destination node together with the intended travel time, destination tracking data is calculated from the stored data. Since the origin-destination relationships of the motions carried out by the mobile units in dependency of all conceivable parameters are known, the destination tracking recommendations for each individual participant can be given such that the sum of the times of movement of all participants is minimized. |
