The subproject deals with the development of novel "human models" in order to address two problem areas in particular: On the one hand, we will find a long period of so-called mixed traffic, in which it will be important for road safety that automated vehicles can estimate how manual drivers behave in road traffic. On the other hand, the acceptance of automated vehicles (from the passenger's point of view) will strongly depend on factors such as driving style and manoeuvres, safety distance, etc. of the automated vehicle. Therefore, individual parameters have to be determined and driving functions have to be parameterized appropriately.
