This report deals with the models of the simulation-tool FLEXSYT-II-. FLEXSYT-II- is instead of FLEXSYT-I- more defined to comprehensively simulative behaviour on motorways and intersections without traffic signs. FLEXSYT-II- has a lot of subprograms from which FLXSIM is the most important. It consists of 6 models to simulate the behaviour of 8 types of vehicles in different circumstances. With these models traffic on a roundabout has been simulated. It turns out that the results of the delays in FLEXSYT-II- are mostly too small in comparison with the field-measurements. Nevertheless FLEXSYT can be used to define the limits of the parameters. The user of FLEXSYT-II- must decide whether these limits are suitable for their purpose. (A)
