- Recently, virtual realities and simulations play important roles in the development of urban traffic infrastructure. By anappropriate abstraction, they help to design, investigate and communicate inner-city development processes. Especially,to investigate interactions between infrastructure and future mobility participants, a valid virtual model is essential forfunctionality and reliability.The aim of this study is the investigation of interactions between a virtual infrastructure model and virtual sensor modelsof highly automated mobility systems. The overall system consists of a georeferenced virtual city model and probabilisticsensor models, which are part of an automated vehicle model. The virtual environment comprises a comprehensive,virtual 3D model of a representative German inner-city scene, considering specific height coordinates. The probabilisticsensor models represent real radar and lidar sensors and comprehensively replicate their physical functionalityin a virtual environment. Considering different levels of detail, the realistic representation of physical effects of thevirtual city model on the virtual sensors is investigated. The investigated scenarios are derived from representativeurban traffic situations. The complexity as well as the level of information of the virtual city scenarios is iterativelyincreased. Subsequently, the effects on the model validity of the overall system is checked and analysed.The results show that the developed virtual environment performs well for different levels of detail of representativevirtual traffic scenes. In addition, the selected modelling depth is very suitable for the high-performance investigationof interaction between virtual urban environment and virtual autonomous vehicle.
