Abstract: Unregulated pedestrian crossings within road intersections can have a significant impact on traffic flows. The consequence of this impact is an increase in the average delay and the average and maximum length of the queue of vehicles at the intersection, an increase in the amount of time in traffic jams and the time people spend in traffic jams [1,4]. Also, do not forget about the number of traffic accidents that occur within pedestrian crossings. Statistics show that every year the number of pedestrian crossings in Ukraine only increases [5]. All the problems listed above are relevant enough to determine the need for detailed research and further measures to solve them. In order to determine the influence of pedestrian flows on traffic flows and to develop measures to improve the organization of traffic at the intersection of Vyhovskoho – Kulparkivska streets, field studies were conducted at stationary posts [2]. Inherent characteristics that allow determining the impact of pedestrian flows on traffic flows are the intensity of traffic and pedestrian flows at the intersection. The key is the fixation of traffic indicators at the intersection during the morning peak, noon peak, evening peak and inter-peak intervals [6,7]. The obtained values regarding the intensity of traffic and pedestrian flows at the intersection of Vyhovskoho – Kulparkivska streets were transferred to the software for modeling transport systems and flows, and results were obtained regarding the average delay time and the average and maximum length of vehicle queues within the intersection [3]. The high average delay time and the average and maximum length of vehicle queues at the intersection indicate a significant impact of pedestrian flows on traffic flows. To solve this problem, a set of engineering measures was developed that will reduce the impact of pedestrian flows on traffic flows and increase traffic safety at the intersection. The proposed options for improving the organization of traffic at the intersection were aimed at reducing the average delay time and the average and maximum length of vehicle queues at the intersection. In the first version of improving the organization of traffic at the intersection of Vyhovskoho – Kulparkivska streets, a decision was made to remove one of the unregulated pedestrian crossings located on the north-eastern side of the intersection on Kulparkivska Street and to install safety islands at pedestrian crossings in other directions of the intersection. In the second situation, a decision was made to eliminate all existing unregulated pedestrian crossings at the intersection and to install underground pedestrian crossings. In the third option for improving the organization of traffic at the intersection, a decision was made to eliminate all existing unregulated pedestrian crossings and arrange four regulated pedestrian crossings on demand. Study object – Self-regulating intersection of St. Vyhovskoho – Kulparkivska. Scope of research – the impact of unregulated pedestrian crossings on traffic flows at the self-regulated intersection of Vyhovskoho – Kulparkivska. Goal of research: to investigate the impact of pedestrian flows on traffic flows at the intersection of Vyhovskoho – Kulparkivska streets and to adopt measures that will help reduce the impact of pedestrian flows on traffic flows and increase the efficiency of the functioning of traffic and pedestrian flows at the intersection under study. As a result of the conducted research, the existing actual intensity of traffic and pedestrian flows at the intersection of St. Vyhovskoho – Kulparkivska, the combined intensity of traffic flows at the intersection was calculated, the average delay time and the average and maximum length of vehicle queues at the studied intersection were determined using the PTV VISSIM software, a complex of engineering measures was developed that would contribute to reducing the impact of pedestrian flows on traffic flows. Keywords – field studies at stationary posts, intensity of traffic flows at the intersection, intensity of pedestrian flows at the intersection, modeling of transport systems and flows, average delay time of vehicles at the intersection, average and maximum length of queues of vehicles at the intersection.
