Abstract: The modern principles of traffic management (TM) have significantly evolved compared to the practices of a decade ago. The main change lies in the adoption of sustainable development principles, which imply a reorientation from car-centric approaches to creating a comfortable and safe environment for all road users. When developing new traffic management schemes, the urban development trends of European and global cities are increasingly taken into account [1–2]. In many European cities, the priority in traffic has shifted to pedestrians and cyclists, who receive the preferential right of way at crossings and on streets specifically designated for movement without the use of engines. A common practice is the reduction of vehicle speed on main streets through the implementation of restricted speed zones, the installation of speed bumps, the expansion of pedestrian areas, and active speed limit enforcement [3]. One of the key approaches to increasing safety has been the separation of traffic flows, which aims to reduce conflict points between different types of road users. This can be achieved using both physical means (e.g., concrete barriers) and spatial organization tools such as road markings [4]. Also important is the re-evaluation of street space utilization: preference is given to residential development, the expansion of pedestrian infrastructure, cycling, and public transport. Reducing the number of parking spaces for private cars, creating recreational areas, and green zones are typical measures for optimizing urban space [5]. In this context, a study dedicated to improving the traffic management scheme at the intersections of Slovatskoho and Universytetska Streets with Doroshenka and Kopernyka Streets in Lviv is relevant. Considering the projected increase in traffic flow intensity, which correlates with the expansion of residential development within the area, the analysis is aimed at adapting the infrastructure to new transport challenges, as well as implementing the concept of a small transport ring in Lviv. Study Object – a section of the street and road network in the central part of the city. Scope of Research – the parameters of the traffic flows moving through this section. The Goal of Research – to justify the application of coordinated regulation on the small transport ring section of Lviv, based on field studies. The influence of the urban development structure on traffic flow parameters and convenience levels, determined by intensity, density, and speed of movement, has been analyzed. The main problems of the central part of Lviv and the potential for applying the small transport ring concept have also been outlined. Methods for field surveys and an approach to optimizing traffic light cycles for synchronized regulation are described. A characteristic of the study area is provided, where most street profiles of the southern corridor allow for two-lane approaches to intersections. It was found that increasing speed from 10 to 80 km/h is accompanied by an increase in stopping distance and a decrease in flow density, while a maximum intensity of about 1378 vehicles/hour is reached at 28–30 km/h. The calculation of coordinated regulation showed that at 25 km/h, it is possible to ensure a green wave with offsets of 10.4 and 32 seconds.Keywords: traffic management, residential complex, traffic flows, traffic signal control, traffic coordination, traffic safety.
