Abstract: The rapid development of motorization is due to many factors that caused it. First of all, this is the need of the population to move, the so-called urban mobility. As the private car provides the opportunity to choose the route, its pace, number and duration of stops, and so on. In such conditions, the role of public transport in urban transport recedes into the background and is used only by those segments of the population who for some financial or physical reasons can not afford to buy your own car or drive it [1]. Every year, the dependence of large cities on cars is growing, which has a negative impact on the duration of travel by all modes of transport and their quality. A separate problem is the ecology of such cities. With this in mind, it is necessary to develop sustainable development (mobility) plans for such cities [2]. Among the main goals and challenges in such strategies is to give priority to public transport, which can be provided by a number of organizational and planning measures [3]. To achieve uniformity of flow in the calculations, a distinct difference is compensated by the reduction coefficients of a conventional car. The study aims to establish the main methods used in the construction of different types of public transport for traditional vehicles and assess the current ratios of buses, trams, and trolleybuses to conventional cars by analyzing the boundary intervals [4-5]. In the reviewed literature, and especially in the regulatory documentation, there are no thorough studies of the dependence of the change in the coefficient of daily unevenness of traffic in traffic flows, depending not only on the time of day but also on the positioning of the data collection point, relative to the attracting city or agglomeration. Study object – transport flow. Scope of research – the patterns of change in the coefficients of the unevenness of the traffic intensity depending on the direction of the traffic flow. Goal of research: based on the results of field studies, to determine the coefficients of the unevenness of the intensity of the traffic flow depending on its direction relative to the attractive city or object. The paper presents the data of the conducted research, namely the intensity of traffic at the research areas and intersections of the district road of Lviv. According to the obtained data, traffic unevenness coefficients were determined in four directions: entering and leaving the city, and cars traveling clockwise and in the opposite direction. After comparing the received coefficients of unevenness with the norms, we can conclude. For accurate values, it is necessary to calculate not only the intensity of car traffic during the day but also the direction of car movement. It was found that the coefficients of the unevenness of the traffic flow can differ from the direction of movement in specific periods, especially during the working day. Keywords – traffic flow, bypass road, unevenness coefficients, unevenness of movement, pendulum migration. References 1. Black, J. (2018). Urban transport planning: Theory and practice (Vol. 4).
