Warnings designed to prevent accidents caused by wrong-way drivers on motorways in Germany

Heavy accidents caused by wrong way driving on motorways happen proportionally seldom but lead to above-average heavy consequences in most of the cases. Therefore, wrong way driving and wrong way driving accidents get a high level of attention in the public perception. The incorrect entering of the motorway thereby represents one of the most common causes for wrong way driving. Within a research project, a new detection system was developed detecting wrong-way drivers on their way up on the wrong carriageway of a motorway. Road users can be promptly supplied with targeted warning messages via an operational headquarter. In the course of this research project, appropriate warning concepts were to develop. This article deals with the validation and optimization of warning concepts in a study with test persons using a driving simulator laboratory.
