Abstract: Public transport is a basic form of urban connections, especially in large urban agglomerations. The urban environment is usually well adapted to the development of this type of movement. The city provides conditions that are key to efficient passenger transport. This is determined by the high population density and the generation of correspondence over short distances [1]. As city bus services are a public service, they can potentially receive subsidies from the city. This is due to its social function. The higher the demand for bus transport, the more efficient public transport services can be offered. Low population density produces less demand for transportation and a greater likelihood of unprofitable work and the need for subsidies [1, 2]. In fact, most public transport systems are not financially sound and need subsidies, even if some of the main segments are profitable [1,3]. Transit systems consist of many types of services, each of which corresponds to a specific market and spatial context. However, they are interconnected, so certain bus routes may depend on tram lines or intercepting car parks [4]. One of the most common forms of urban transport is bus routes, which include the use of vehicles of various sizes (from small minibuses to multi-section buses) in which transportation is carried out on seats or standing [5]. They tend to travel on the general carriageway and are therefore sensitive to congestion. The main advantage of this type of transportation is their maneuverability and flexibility. However, miscalculations in the management of passenger traffic as well as inefficient management lead to poor quality of service, which in turn reduces the competitiveness of this type of movement. This is a dangerous phenomenon in cities that are moving towards car dependence. It is important to study in detail the patterns of changes in the functioning of bus routes depending on factors such as passenger traffic and traffic conditions and parameters of the road network. Study object – city bus route. Scope of research – patterns of change in performance indicators of the route. Goal of research: based on the results of the analysis of the unevenness of passenger traffic on the route №24, as well as the level of vehicle load to establish the dependence of changes in the performance of the route from these factors. ? The decision regarding the period of replacement of small-capacity buses with larger vehicles will be made when the regular maximum occupancy of the vehicles reaches 100% of the nominal capacity. The slide shows the results of modeling changes in the occupancy of a small-capacity bus, taking into account prospective passenger traffic. Based on the obtained mathematical model, it can be noted that under an optimistic scenario, the replacement of rolling stock on the bus route should be carried out between the fifth and sixth months of the operation of the route project. The mathematical model of change of productivity of work of the bus for an hour taking into account the coefficient of unevenness of a passenger traffic and level of loading of a street and road network is received. Keywords - passenger transportation, city bus route, technical and operational indicators, traffic interval, passenger traffic. References 1. Rodrigue, J. P. (2016).
