Modelling the driving behaviour influenced by information technologies

It turned out to be useful to estimate possible effects of onboard information technologies on traffic flow before the start of introduction. One possibility for doing this is the simulation of traffic flow. Hence, a theoretical model has been developed, describing the influence of information technologies on driving behaviour. This model has been integrated into a microscopic traffic simulation system. Described in this paper are human driving behaviour with the driver supported by additional information, as well as automatic driving behaviour, with special equipment controlling vehicle movement. Differences in traffic flow between not supported, partially supported and completely supported driving are shown, being a result of preliminary investigations.
