“…Giuffre et al (2017) presented the results of estimation of passenger car equivalents for single-lane roundabouts using a microsimulation-based procedure (AIMSUN). Kollar (2014) also presented the results of estimation of passenger car equivalents using a microsimulation based procedure (VISSIM). Based on the output of multiple runs of the different mixed fleet scenarios simulated in Aimsun, capacity functions for each lane from the turbo-roundabout entries were developed and the E i for heavy vehicles driving turbo-roundabouts were calculated by comparing a fleet of passenger cars only with a mixed fleet characterized each time by different percentages of heavy vehicles Giuffre et al, 2016b Measuring the effect of heavy vehicles on operational conditions of a turbo-roundabout using microsimulation (AIMSUN)…”

The presence of heavy and slower vehicles within the traffic stream significantly reduces traffic capacity. This reduction increases with the higher participation of heavy vehicles in the stream, which, compared to passenger cars, move at a lower speed. Furthermore, they occupy more space on the road, are characterized by a longer reaction time to the road traffic situations, and put greater pressure on the surface structure, etc. In order to conduct analyses related to determination of the conditions in the traffic stream, the traffic stream mixed in terms of composition is converted from real vehicles into passenger car equivalents. For this purpose, the passenger car equivalent factors (Ei) appropriate for a given group of vehicles are used. The paper presents the results of a study aimed to determine the numerical values of passenger car equivalent factors for heavy vehicles (trucks, buses, trucks with trailers, articulated buses) on turbo roundabouts. The research was carried out on turbo roundabouts located in Poland.

Traffic control strategies of signalized circular intersections are analyzed in this article after a brief overview of traffic lights in roundabouts. A detailed description was made on the 'direct' mode of operation of the Hungarian regulation describing three types of control program. Finally a comparison of traffic performance is given based on the main geometric features and parameters of the signal programs with a description of the signal plan structure. The PTV Vissim environment was used to examine and evaluate the performance of each combination through the average delay per vehicle resulting proposals for the application as well as for further studies in subject.
