The DLR Institute of Transportation Systems is dedicated to the comprehensive investigation of current traffic conditions. Using cameras and sensors, traffic on motorways (Test Bed Lower Saxony) and in the city (research intersection) is recorded digitally and analysed and visualised by researchers. This enables a detailed investigation of normal and critical situations and the development of preventative solutions. The modelling also serves as the basis for simulation models (SUMO), which aim to optimise traffic control. In a future traffic world in which automated vehicles interact not only with each other, but also with cyclists and pedestrians, understanding the interactions is essential. This is also being researched through test subject studies in the Institute's simulation laboratories (MoSAIC laboratory). The topics presented in the film originate from the 'Modellierung des Verkehrsgeschehens' group within the 'Information Acquisition and Model Design' department.
