The question of research of bases of operation of means of transport at intercity passenger route transportations was considered in the thesis. It was established that the process of operation of means of transport in long-distance passenger traffic is not isolated. This determines the influence of the environment on the quantitative indicators of the parameters of such a process, due to the possibility of quantitative changes in the conditions of the mentioned operation of means of transport in long-distance passenger traffic. The paper uses a network analysis, which is used to formalize the transport process parameters. The definition of the straightness coefficient of the road network is given. The actual values of this coefficient of the object of research are calculated, which can be characterized by the quality of the drawing and the influence of road networks on the characteristics of the variants of connections between its nodes. In the study, previously unknown parameters of the gravity function were established, which provides an opportunity to predict the correspondence of passengers in the investigated system. This parameter is the calibration factor, taking into account the influence of the distance between cities. An experiment was conducted on theoretical and experimental studies. A comparison of the obtained theoretical and experimental data was conducted, the results of which showed the static error of calculations. The obtained information on the parameters of the investigated correspondence was supplemented by the well-known scientific approaches to forecasting the parameters of the operation of the process of transportation of passengers with the definition of the characteristics of seasonal fluctuations in demand for transportation, which provides an opportunity to predict the correspondence of passengers in the investigated system using gravitational modeling. It is established that when changing the distribution of passenger traffic between road and rail route networks there are direct proportional changes in linear dependences of quantitative characteristics of the basic indicators of the systems themselves, namely: changes in the number in the route network, the number of passengers transported, transport work, changes in the required number of vehicles. The logarithmic dependence of the average system coefficient of occupancy rate on the distribution of passenger flows between road and railway route networks is determined. It is proved that when changing the parameters of distribution of passenger traffic between automobile and railway route networks, the quantitative mean values of the average length of the route and medium network range of the ride are not significantly changed, and the transfer rate factor remains unchanged. It is determined that changing the speed of the route is such a factor that does not affect the quantitative values of the number of movements in the network, the transfer rate, the average distance of the route. At the same time, the existence of a polynomial dependence of the average system passenger capacity rate and the number of buses on the speed of route/network rides has been proved.
