Calibration of car traffic bringing RDE tracks close to reality

Virtual simulation needs to replicate real-world situations as well as possible. When performing simulations with traffic, often only the individual behavior of the surrounding traffic is of importance and general traffic patterns are neglected. That is, for example, realistic paths of vehicles that determine the weaving/merging rates but also realistic speed-flow relationships. In this presentation, we introduce how to calibrate traffic simulations using origin-destination matrices based on GPS data, video footage and other sources to achieve a realistic representation of traffic flow in your virtual tests.
