Abstract: The trend of increasing the number of rolling stock in settlements leads to the appearance of new problems regarding the organization of traffic on the street and road networks of cities and complicates the movement of public transport. At the same time, the primary indicators of traffic flows, in particular speed, intensity and density, often acquire worse values. This often happens due to an increase in the number of vehicles on the street and road networks of settlements. In such cases, the average speed of traffic decreases and the density of the traffic flow increases, which often leads to the formation of traffic jams. Which, in turn, increases the time for which public transport moves from the beginning to the end of its route [1]. The speed of public transport directly depends on the loading of the road network. At the same time, it should be taken into account that the level of motorization increases every year, and the capacity of intersections does not change. At the same time, Lviv is a city with a long history, where it is very difficult to implement changes regarding the improvement of the street and road network, its planning and improvement of traffic organization schemes. Therefore, it is necessary to apply both complex and point improvements that will satisfy the needs of all participants of the movement to a certain extent [2, 3]. This master’s degree thesis, examines the section of the street and road network of the city of Lviv, in particular the regulated intersection of Stryyska - Chmoli streets. The main problem of this intersection is the delay of vehicles on the approaches to it, in particular public transport. Due to the insufficient capacity of this intersection, significant traffic jams are formed. Also, as statistics show, there is a significant traffic accident at this intersection. The decision was made regarding the expansion of the roadway on the approaches to the Stryiska Str. – Chmoly Str. intersection. At the same time, the red lines of the city’s development make it possible to implement such an engineering solution. Public transport lanes will be located on the street. Stryyska in both directions. On the approach to the intersection towards the center, it is planned to install one lane of public transport, which will be adjacent to traffic flows turning right onto Chmoly Str., which in turn will reduce the costs of such an installation. Based on the created traffic organization scheme, calculations were made regarding the duration of the main elements of traffic light regulation. To determine the feasibility of the proposed project, a traffic simulation model was created in the PTV Vissim software environment. Based on this, the length of time vehicles stay in traffic jams and the average length of traffic jams are determined. The object of research is the regulated intersection of Stryiska Str. – Chmoly Str. The subject of research is the patterns of traffic delays and their impact on traffic flow indicators. The purpose of the research is to create a design model of the traffic organization scheme at the intersection of Stryiska Str. – Chmoly Str. in the PTV Vissim program. Taking into account the results of natural and documentary research. Key words – traffic volume, traffic speed, traffic safety, traffic light, public transport lanes, public transport, PTV Vissim.
