Abstract

UA: Запропоновано підходи до визначення попиту на швидкісні залізничні пасажирські перевезення у великих містах, розроблено теоретичні основи реалізації інтервальної концепції моделювання попиту на переміщення. У подальшому подані дослідження можуть бути використані для визначення доцільності функціонування швидкісних пасажирських перевезень у великих містах, компонування составів та складання розкладу руху швидкісних поїздів, побудови та реконструкції залізничної інфраструктури.

EN: The offered approaches to the definition of demand for high-speed rail passenger transportation in large cities, the theoretical bases of realization of the interval concept of modeling of demand for movement are developed. The value of capacity of transport areas is proposed to be determined based on the results of surveys of passenger traffic on high-speed rail transport. This is due to the fact that these characteristics of the transport process are the most objective and stable. The calculation of capacity of transport areas is carried out in two main stages. At the first, the capacity for departure and arrival within the higher transport areas is determined. At the second stage, the values of the capacities of the higher transport areas are locally allocated between the transport areas within their borders. The main parameters for which the distribution is carried out is the population density and density of workplaces, taking into account the size of the transport areas. The basis for local distribution of capacities on large areas of urban territory, for which it is impossible to provide a large degree of detail of transport characteristics, may be the characteristics of resettlement and employment of the population. A prerequisite for modeling a passenger correspondence matrix is the implementation of a number of constraints in which the determination of demand for passenger high-speed rail services can be considered correct. The criteria for optimization are the amount of transport work and the average range of passengers. The conducted research is the basis for developing a model of job density and building an imitation model for the formation of demand conditions for high-speed rail passenger traffic in large cities. Subsequent studies may be used to determine the expediency of high-speed passenger transportation in large cities, layout of compilations and scheduling of high-speed trains, construction and reconstruction of railway infrastructure.
