IMPROVEMENT OF TRAFFIC MANAGEMENT AT THE INTERSECTION OF SOBORNA STREET AND HEROIV TANKISTIV STREET IN THE CITY OF FASTIV, KYIV REGION

Abstract

The paper focuses on improving traffic management at the uncontrolled Y-shaped intersection of Soborna Street and Heroiv Tankistiv Street in the city of Fastiv, Kyiv Region. The selected transport junction is characterized by heavy traffic volumes, difficult topographic conditions, and restricted visibility, all of which negatively affect road safety and traffic performance. A comprehensive assessment of the existing traffic organization was conducted to identify the key factors contributing to operational inefficiency and an increased risk of traffic accidents. The complexity of the intersection was evaluated using the G.A. Rappoport method, which is based on the quantitative assessment of conflict points formed by interactions between vehicle and pedestrian traffic flows. Based on the analysis, an improved traffic management scheme was developed involving the introduction of a roundabout designed according to turbo roundabout principles. The proposed solution includes channelizing islands, relocation of the pedestrian crossing outside the intersection area, and the installation of an appropriate system of road signs and pavement markings. The scientific novelty of the study consists in proposing and substantiating an integrated approach to the modernization of an existing urban intersection that considers its geometric configuration, traffic demand, terrain characteristics, and applicable regulatory requirements. In addition, a conservative approach to the assessment of conflict points within the circulatory roadway was employed to obtain a reliable comparison of the existing and proposed traffic layouts. The results indicate that implementation of the proposed design decreases the intersection complexity index from 57 to 22 points, significantly reducing the number of potential conflict points, improving road safety, and increasing the operational efficiency of the transport junction. The practical value of the research lies in the applicability of the proposed engineering solutions to the reconstruction of similar urban intersections and to the development of traffic management improvement projects for urban road networks throughout Ukraine.
