The object of research is the influence of the conditions for the implementation of technological trip operations in the implementation of the priority movement of urban passenger transport on the bus route on the level of accessibility of the transport service. On the basis of the developed contour of information communication, a typical procedure for establishing the parameter for assessing the availability of a transport service, depending on the time indicators of traffic on the route, is singled out. As a controlled parameter that determines the conditions for increasing the availability of a transport service, the trip time and the range of deviations in the arrival of buses to the stopping point are singled out. Implemented on the basis of simulation modeling, the procedure for establishing the correspondence between the time parameters of the departure of buses from the stopping point and the formation of demand made it possible to establish patterns of changes in the level of accessibility of the transport service depending on the traffic conditions on the route. In the course of field observations along route No.115e «Gagarin avenue metro station – Nesterov street» (Kharkiv, Ukraine) it was found that the introduction of free traffic conditions that meet the conditions of the priority of urban passenger transport can reduce the duration of the trip by 5min and reduce the range of deviation of the arrival of buses to the stopping point by 4min. On the basis of experimental studies, it was found that by reducing the duration of the trip from 32min up to 27min it is possible to increase the value of the transport service accessibility indicator by 20.5%. When organizing traffic according to a schedule, it is possible to increase the indicator of the availability of transport services up to 0.679 (by 6.8%). The introduction of priority traffic on route No.115e allows reducing the trip time to 22–27min, which will positively affect the indicator of the availability of transport services (increase to 0.803 in traffic without a schedule and up to 0.880 in compliance with the traffic schedule). Reducing the range of bus arrival deviations in the range from –1min up to +2min allows increasing the level of accessibility of transport services under normal conditions from 6.8% to 13.3%, and with the introduction of priority traffic – from 15.4% to 18.3%.

The object of the study is the effect of the downtime of vehicles at stopping points on the duration of the route between passengers within the transport hub. As a controllable parameter that determines the conditions for synchronizing the presence of vehicles at stopping points and reproduces the characteristic effect on the weighted average time spent by passengers in transport hubs, the time of additional service downtime of vehicles is allocated. The simulation modeling and processing of the results obtained made it possible to establish the characteristic patterns of changes in the time spent by passengers in transport hubs for two types of routes with different volumes of passenger arrivals, the proportion of inter-route transfers and the interval of movement. It was found that for routes with scheduled arrivals more than 40 passengers and the specific gravity of inter-route transfers up to 45%, the introduction of additional service downtime does not allow a positive effect on the duration of the stay of passengers in transport hubs. The implementation of service downtime is advisable for routes with an average volume of regular arrivals of passengers (up to 40 passengers) and a specific weight of inter-route transfers of more than 45%. For such conditions, the regularities are described by a third-degree polynomial with the available characteristic period, which minimizes the function of the time spent by passengers. On the basis of the conducted experimental studies, it has been established that for routes with a specific gravity of a change from 45% to 59%, it is advisable to have a service downtime in the range of 1minute up to 3minutes, and for routes with a transfer rate of more than 59% – within 2minutes up to 5minutes. The use of service downtime will increase the effectiveness of the synchronization of inter-route transfers in conditions of stochastic traffic and reduce the time spent by passengers in the transport interchange hub by 0.9–3.9minutes (14–38%) in comparison with the existing organization of interaction between the subjects of the route flow.

The object of research is the effect of the time spent by vehicles at the stopping point on indicators of the level of conflict in the interaction of the route flow. As a controlled parameter that determines the level of reserve capacity of the stopping point and reproduces the characteristic effect on the conflict of interaction, the additional service downtime of vehicles is allocated. Simulation and statistical processing of the results are used, which allow to establish typical types of patterns for stopping points with different intensities of the input route flow. It has been established that for stopping points with low and medium intensity (up to 40 vehicles/h), the reserve of throughput has an inverse linear dependence on the service time and for exponentials with high intensities (more than 40 vehicles/h) it is exponential. Changing the reserve of bandwidth by setting a rational service idle duration allows to affect the number of conflicts and the length of time in the queue. This makes it possible to determine its acceptable values for the corresponding intensity level of the route flow. Based on the conducted experimental studies, it is established that an additional service downtime for a stopping point with intensity of up to 40 vehicles is an acceptable duration of up to 40 s. With the introduction of more than 125 s – in 71.2% of the incoming stream, conflict situations will be observed. From the position of minimizing the conflict of interaction between stopping points with an input route flow intensity of more than 40 vehicles/h, the introduction of an additional service downtime is not at all possible. Establishing dependence is the methodological basis for the formation of elements of a management decision support system based on an analysis of the impact of vehicle downtime on the conflicting interaction of the route flow. They introduce certain orderliness in the processes of planning the work of passenger infrastructure facilities, make it possible to systematize their service-resource parameters and contribute to improving the safety of passenger transport services.

The article considers the original, author developed calculation method of forming a rational passenger traffic, which parameters are one of the most important conditions for stable operation of the transport system of the cities, and as a result, the fulfillment of its main goal – the carriage of passengers. The article covers both: theoretical reasoning and practical recommendations to provide the stable operation of the transport undertaking due to the complex of measures to improve the efficiency of its operation with the scientific and economic point of view. It requires development of a rational route network, which provides a possibility of choice for passengers between several route options with the minimum time difference from the shortest way between the origin and destination. And only after that the passenger traffic of the route network is calculated by our method. The offered method allows to calculate on probabilistic basis the required number of routes to provide the full realization of passenger flows transportation in the cities.
