This master's thesis presents the procedure for selecting the optimal type of intersection in the peripheral zone of urban space, using the example of two intersections located in the area of the city of Poreč. The two observed intersections are: the intersection of Ulica Županija Somogy, Anka Butorac and Ivo Lola Ribar and the intersection of Ulica Županija Somogy, Vitomir Širola Paja and Bruno Valenti. The selection of the optimal type of intersections involves the analysis of location, traffic analysis and other parameters. The procedure for selecting the optimal type of intersection in urban areas is quite complex due to the need to meet requirements of different types of traffic, spatial limitations and the need to respect the environment. At the beginning of the study, the requirements for designing intersections at grade and the criteria for selecting the optimal type of intersection are specified. An analysis of the existing conditions has been conducted, which includes an analysis of the geometric elements of the intersection, traffic organization at the intersection, pedestrian and bicycle traffic, conflict points and visibility. The proposed new solutions are in accordance with the urban development plan of the residential area of Poreč. The solutions aim to improve traffic flow at the given location, primarily from the perspective of traffic safety. The proposed solutions include conventional three-way and four-way intersections at grade, as well as roundabouts. The design alternatives for roundabouts were developed following the guidelines for designing roundabouts on national roads. A total of 10 solution variants were developed for both intersections. The process of selecting the most favorable solution was carried out in two steps – elimination based on a smaller number of criteria and a detailed comparison of solutions in the second step. In the first step, based on the criteria of conflict points, traffic drivability and non-motorized traffic safety, the options for the intersection of Ulica Županija Somogy, Anka Butorac and Ivo Lola Ribar were narrowed down to three possible solutions that performed best according to the observed criteria. In the second step, three variants for each intersection were compared and scored against each other and the existing conditions. The comparison was carried out according to the criteria defined in the guidelines for designing roundabouts on national roads, with sub-criteria adapted to the observed situation. The final solutions selected were the intersections that better met the established criteria and were further elaborated and presented in graphical attachments.
