Roundabout arm capacity determined by microsimulation and discrete functions techniqueTollazzi, Tomaž (Avtor) Šraml, Matjaž (Avtor) Lerher, Tone (Avtor) roundaboutstraffic flow analysismicro-simulation modellingcapacity analysisThe paper demonstrates the influence of the multi-channel pedestrian flow on the actual capacity of a one-lane roundabout, using micro-simulation and discrete functions. The proposed model is based on the theory of the expected time gap between the units of pedestrian traffic flow, which have the priority when crossing the arm of the roundabout. The proposed model represents an upgrade of the previous research in the field of modelling traffic flows in the one-lane roundabout.Apart from the multi-channel pedestrian flow the disturbances caused by the circular traffic flow of motorised vehicles at the roundabout are also considered. In this way the model can better illustrate the real conditions in traffic. A simulation analysis has been performed on the roundabout arm at Koroška Street in Maribor. The results of the analysis have indicated a relatively high reserve of the actual throughput capacity for the main motorized traffic flow in the analysed roundabout arm. The presented model represents a practicable and adaptable tool for planning the roundabout capacity in practice and for the sensitivity analysis of individual variables on the throughput capacity of the roundabout.20082017-06-05 11:52:21Znanstveno delo66041ISSN: 0353-5320UDK: 625.739:656OceCobissID: 1416196COBISS_ID: 12787222DOI: 10.7307/ptt.v21i5.1013ISSN pri članku: 0353-5320NUK URN: URN:SI:UM:DK:3ZLDQRISsl
