Turning accidents are among the most common accidents involving cyclists. Traffic behaviour can be observed among both cyclists and motorists that is unfavourable or promotes risk. However, the design of junctions also has an influence on the accident occurrence.

On behalf of the Insurers Accident Research (UDV), we analysed existing cycling infrastructure at high-accident junctions and typical road user behaviour patterns in four different communes (Münster, Erfurt, Darmstadt and Magdeburg).

In this project, we developed a hypothetical impact model that showed the complex correlations in the area of conflict. In addition, we conducted comprehensive traffic observations in the four communes and surveyed the traffic behaviour and attitudes of road users.

Within the framework of the project, we have developed recommendations for infrastructure design and cycling routing at urban intersections, but also for the education of motorists and cyclists. In addition, we were able to derive further information for the development of driver assistance systems.
