Wide range traffic monitoring for the tracking of overtaking manoeuvres is an issue of current research. The collected data will allow the updating of a model which describes overtaking manoeuvres depending on various boundary conditions. The model is used for road planning, e.g. recommendations may be provided to decide where driving on the oncoming traffic lane cannot be allowed due to traffic safety. The necessary update of the model requires wide area traffic observation. This challenging task has been solved by recording aerial image sequences in combination with an automated image analysis.
