In this paper the approach, the challenges and the results of determining the effects of cooperative Intelligent Transportation Systems on traffic efficiency and traffic safety using the example of the simTD project are presented. It is shown that the integrated approach using a driving simulator and traffic simulation offers a valuable complement to the analysis of real traffic and that some challenges associated with using real world data could be overcome by using simulation. The effects of selected evaluated cooperative functions in urban and inter-urban contexts in traffic simulations as well as real traffic regarding the performance indicators specified uniformly for all test environments (traffic simulation, field operational test) are described.     «
