Study of the Dimensions of Suburban Trains Movement on the Site by the Integer Programming Method

In this article, it is proposed to determine the size of the movement of suburban trains on the section for all periods of the day by the integer programming method. This calculation method makes it possible to increase the competitiveness of railway transport, reduce the loss of a part of passengers due to the transition to alternative modes of transport. Traffic dimensions, which can be obtained using the integer programming method, make it possible to simplify the development of prospective schedules of train traffic, taking into account the needs of the population in transportation. The research results can also be used in the technical and economic justifications for the reconstruction of track development of stations and passenger devices, as well as serve as a basis for technical re-equipment of lines with the aim of increasing their throughput (replacement of signaling and communication means, construction of second main tracks, reconstruction of station entrances, etc.). The results of the calculation also make it possible to identify schedule “threads” for removing trains on days of the week when they are not in demand, but at the same time take into account non-daily trains when developing a normative train schedule. The results of the calculations take into account the spatial unevenness of the passenger flow and make it possible to distinguish zone trains.
