RESEARCH OF REGULARITIES OF PASSENGER FLOWS IN THE RAIL SUBURBAN TRAFFIC

Purpose. Determining regularities of changes of trains occupancy and the approach commuters on landing for determining the technical and technological parameters of suburban passenger services. Methodology. To achieve this goal were identified research methods of train occupancy, basic approach periods of passengers to platform affecting the occupancy of carriages in different periods of the day. Findings. On the basis of conducted researches can be carried out comlex, systematically related calculations of important technical and technological parameters of suburban passenger transportations. To such parameters can be attributed parameters of trains timetable, occupancy of carriages, the number of ticket offices, passenger platforms size, number and location on them turnstiles, providing the comfortable and safe boarding of passengers on commuter trains. It is proposed to use the relative indicators of trains occupancy and generalized theoretical dependencies of approach intensity of passengers on landing in trains. There are graphs where there is unevenness of transportation demand, which is estimated by actual train occupancy that is established by direct natural supervision in train carriages. Results of the study hourly of passenger flow distribution have allowed to establish that irregularity by period of day has a pronounced character of manifestation, especially in the morning and evening during the "peak" periods. Dimensions of transportations in these hours do not meet comfortable conditions of passenger travel in suburban trains. Originality. It was suggested the new approach to determine regularities of changes of the suburban trains occupancy to approach commuters to platform. It is presented the comparisons of actual distribution curves and approximated theoretical curves of approach intensities of passengers and filling of trains, and the formula by which the described patterns are identified. These formulas can be used to construct appropriate mathematical models describing the process to approach of passengers on landing in trains. Practical value. Using of obtained regularities will allow in future predict the number of passengers in specific trains, thus optimizing the schedule of commuter trains the interval between trains, as well as the required number of rolling stock
