In this article a hybrid driver model is described which has been developped at the Institute for Industrial Information Systems (IIIT) of the University of Karlsruhe. After a short introduction into the subject an overview over the human information perception and processing is given. A concept is presented which adapts the human behaviour to a realistic driver model. The developped driver model, which is composed of a queueing network and two GPC-controllers, is described. For the purpose of simulation three different driver types are defined and simulation results are discussed.
