METHOD AND APPARATUS FOR TRANSFERRING BASIC FORMS OF TRAFFIC TROUBLES FOR THE PURPOSE OF TIME-RELATED NAVIGATION

摘要

The invention relates to, in essence, a method for transmitting information to terminals, which describe traffic disruptions. The method comprises the following steps. In a first step, items of information are encoded that describe the traffic disturbance in the path-time diagram. This path-time diagram, however, is not rectangular. The hereby encoded items of information are transmitted to the terminal that, in turn, decodes the items of information. The terminal determines the path-time diagram and calculates a possible traffic disturbance on the basis of this path-time diagram. Based on the recorded items of information of the terminal that is preferably a navigation unit, the items of information being time of day, position and speed, it can be calculated whether the traffic disruption has an influence on the driving time in order to then optionally determine an alternative route or to recalculate the expected time of arrival. The transmitted path-time diagrams consist essentially of triangles or parallelograms.
