Passenger car unit is an important comparison factor that helps the traffic engineer to describe the impact of heterogeneous traffic flows on the traffic performance of the infrastructure elements, compared to homogenous passenger car flows. The purpose of this study is to determine the passenger car unit value of certain vehicle types (e.g. buses, trucks) in signalized circular intersections. The values defined by the Hungarian standards are based on the weight and type of the vehicles, so it is important to know how these parameters of the vehicles influence the traffic conditions at this unique type of road junction, to be able to conduct a correct capacity calculation. PTV Vissim microscopic simulation program was used to model different traffic volumes and compositions getting by the recommended passenger car unit values for the application, and a proposal for further studies in subject.
