Using microsimulation models during the designs of transport infrastructure is increasingly common in many countries of the world, and in this thesis is applied on the traffic network of the urban area Pecine. Advances in technology are advancing and developing microsimulation models that wants to describe and forecast traffic trends more realistically. Based on the analysis of traffic and spatial indicators, the main problems in the area were concluded: high speeds of vehicles in the zone and lack of parking areas. All solutions were guided by the most important traffic criteria which include traffic flow and traffic safety and they are based on the traffic safety projects that aim preventing occurrence of accident with project solutions and by interventions in infrastructure. Solutions include the reconstruction of three-leg intersections into the roundabouts who are generally implemented at locations where the traffic wants to slow down, and since the mentioned intersections are located at the eastern entrance into the city, this is an excellent warning measure for drivers who are entering the low speed zone. Considering the actual amount of traffic load in the urban area and due to the lack of parking spaces, the numbers of traffic lanes in both main streets are reduced, and also is introduced street parking and parking lots at several locations along the urban area Pecine. The possibility of introducing a cycling lane was also analyzed. The results of the microsimulations which covers all the mentioned spatial - traffic solutions of urban settlement Pecine confirm that the proposed changes will advance the entire transport infrastructure of settlement.
