Abstract: Increasing the level of motorization of the population accelerates economic processes, economic growth, modernization of transport and public infrastructure, increasing investment in infrastructure. Motorization takes the country to the next stages of urbanization, introduces the concept of "suburbs" and provokes the emergence of urban agglomerations [1]. Motorization also opens up new opportunities for people in depressed regions to realize their human potential, do business, work, move property, and receive medical and educational services. The rate of circulation of human capital within the country is increasing [1]. However, the rapid growth of the individual fleet leads to a significant increase in traffic intensity and load on the city’s road infrastructure. Studies of traffic flows show that the main street network operates at its limit, and in some areas its capacity is completely exhausted. The main reason for the difficult transport situation in the city is the lack of proportionality between the development of transport infrastructure and the growth of motorization and car use [2-3]. One of the main negative effects is significant and frequent delays in traffic. Congestion is one of the most common transport problems in large cities and agglomerations. Given that such a negative phenomenon is observed in those cities or regions where there is a high level of economic development, it is worth paying attention to settlements with more than 500 thousand inhabitants. Congestion is most often associated with the growth of car use and the availability of cars, which increases the demand for transport infrastructure. However, the level of infrastructure development may not always meet the demand for movement. It is also worth noting that according to research and surveys, in the 21st century, drivers are three times more likely to get into traffic jams than it was in the second half of the 20th century [4-5]. Study object – traffic flow. Scope of research – patterns of changes in traffic intensity over time. ? Goal of research: using scientific and technical approaches to determine the reserves of capacity in areas of the city road network. According to the research results, the value of traffic flow intensities on the part of the street and road network in the Frankivsk district of Lviv was established. An analytical calculation of the capacity of sections of the road network was carried out, taking into account previous studies on traffic regimes on them. Traffic intensity forecasting was carried out on highways and streets of local significance. According to the results of calculations, the existing and prospective level of loading is determined. However, based on the obtained data, a conclusion was made regarding the timeframe when the state of the existing infrastructure will not meet the demand for transport. Keywords - traffic organization, traffic flow, traffic intensity, forecasting, load level, road network. References 1. How Ukrainians are fighting for the country’s motorization..
