Abstract: In the middle of the 20th century, an impetuous development of motorization was observed. Although this phenomenon appeared already in the 1960s and 1970s in the United States of America, now it is common in most countries of the world [1-2]. Despite several global oil and economic crises in the past, the automotive and automotive industries have successfully adapted to the new conditions, gaining further development and popularity. In modern times, road transport has become one of the main sources of atmospheric air pollution. The biggest negative impact of road transport on ecology is found in large cities, covering not only emissions of harmful substances, but also noise pollution [3]. Despite the trend towards hybrid and electric cars in the modern world, the global transition from large-capacity power units to small-capacity ones has not yet taken place [4]. This indicates that the environmental situation will not change suddenly, especially due to the lack of changes in the structure of the car fleet. Cities, which are marked by large-scale industry and are aimed at the production of specific goods and profit maximization, do not always emphasize the comfort of life, which can be explained by the lack of population dynamics. This means that a change in the transport approach is appropriate in all European and Ukrainian cities, and in such cases ecological traffic management schemes should be evaluated and measures taken to improve them. This is especially important in some cities or agglomerations, where this may be the only opportunity to improve the environmental situation, since the prospects for reducing the number of cars or changing their structure are remote [5]. The competitiveness of urban modes of transport depends first of all on the speed of communication, then on the comfort, reliability and safety of traffic. The main factor that makes electric transport an alternative is the cost of transportation, since trolleybuses have been serving discounted passengers for a long time. In order to know how to optimize the speed of connecting trolleybuses, it is necessary to conduct thorough studies of the modes of movement of these vehicles on the city’s street and road network. ? Study object – city trolleybus route. Scope of research is the specifics of changes in passenger traffic upon the introduction of trolleybus traffic on new sections. The purpose of the study: using macro models, to estimate the prospective passenger flow during the extension of the trolleybus route and to calculate traffic modes for it. The main regularities in the change of parameters of traffic flows on the street and road network of the city are analyzed. The main indicators of the quality of service to users of city streets and the parameters of passenger transport systems are characterized. Field studies were conducted and based on their analysis, an assessment of the influence of traffic flow parameters on trolleybus operating modes was provided. The weight of factors affecting the speed modes of movement of transport units and their ranking were established. It was determined that seasonality is also an important aspect that depends on the loading of the streets and, therefore, the duration of the flights. Keywords - city trolleybus route, passenger flow, autonomous trolleybuses, main streets, service areas. References 1. Arvis, J. F., Saslavsky, D., Ojala, L., Shepherd, B., Busch, C., & Raj, A.
