Retracted Article: Calculation of maximum allowable capacity coefficient for urban passenger transport

Abstract

One of the most important indicators of the quality of transport services to the population is the coefficient of the use of rolling stock capacity. This parameter directly affects economic efficiency of the transport organization: the carrier is concerned with the highest value of the capacity utilization coefficient. The passenger, on the contrary, prefers service without overcrowding of the rolling stock. In practice, the average coefficient of dynamic capacity utilization for the relevant period is calculated, which is used in determining passenger fares, the analysis of the performed traffic in terms of available reserves of carrying capacity, planning of the transportation process. The paper considers the methodology of calculating the maximum permissible value of the coefficient of capacity utilization, on the basis of ensuring the normal occupancy of the cabin throughout the routes during the entire period of transport movement. The solution to determine the maximum permissible occupancy of rolling stock at work on regular city routes is offered, the task on the basis of analysis of dependence of the factor of use of capacity from parameters of passenger flows, average time of work of rolling stock on the route and non-uniformity of speed of communication during the work of passenger transport is offered. It was proposed to estimate the fluctuations of the communication speed during the movement of urban passenger transport by means of the coefficient of non-uniformity of the communication speed. It is established that the coefficient of using the rolling stock capacity depends substantially on the parameters of passenger flows, the average operating time of the rolling stock on the route and the unevenness of the speed of communication during the period of transport operation.The obtained dependencies make it possible to calculate the maximum permissible value of the capacity factor, taking into account the parameters of the planned transport process. Depending on the operating conditions, the capacity utilization factor varies within a significant range from 0.2 to 0.4.
