Hitherto the entry/circulating flow relationship at roundabout entries has been studied by either a semi-empirical or an empirical approach. A new approach which involves simulating traffic at roundabouts on a computer is now considered. The simulation has been applied to study the interaction between the entry and circulating flows at five entry sites. Comparison of results from the simulation model with observed data shows that the simulation represents reality fairly well. The simulation also predicts as well as, if not better than, two of the generalised relationship established by the former approaches. For the covering abstract of the seminar see TRIS 450556.
