Application of traffic simulation models for urban road network analyses – case studies from Rijeka city

The process of road network planning and designing in urban areas can be signifcantly improved by using microsimulation of trafc models. Trafc microsimulations are used for analyses and estimation of new proposals as well as for the reconstruction of existing infrastructure in order to reach optimum solution for defned problem. In this paper, applications of different analyses approaches are analyzed in two case studies. Both case studies are located in the city of Rieka but in different parts of the city, in different trafc conditions and in circumstances where different changes in trafc network are planned. In both cases new solutions were tested through VISSIM trafc model and by application of SIDRA Intersection methodology. VISSIM is a stochastic, discrete, micro-simulation model designed for trafc analyses while SIDRA Intersection is a lane-based micro- analytical model. The results proved the suitability as well as advantages and disadvantages of both approaches. The paper contains suggestions for optimal application of selected models regarding different trafc problems.
