The „Finkenwerder Ring“ is an important traffic junction in the Port of Hamburg – however, a lot of accidents per year impair traffic safety and reliability. The current traffic management, the signage, and the high number of lanes might be causal for the many crashes. Therefore, a requirements analysis was conducted to investigate the current traffic situation of the Finkenwerder Ring. Based on these results possible countermeasures were identified and subsequently implemented in a reproduction of the Finkenwerder Ring in a driving simulation. Four variations of the Finkenwerder Ring were realized which differ in signage and roadway geometry and were evaluated in a driving simulator study with N=30 participants. Even a small implementation like a modification of signage is able to have positive effects on drivers’ evaluations. However, a quite expensive and complex solution (the separation of traffic streams via an additional traffic light) shows the largest effect. These results show the benefit of driving simulation as a tool for roadway design.
