THE IMPLEMENTATION OF ACCELERATED TRAINS OF INTERREGION CONNECTION

Abstract

One of the main directions of improving the efficiency of passenger transportation is the introduction of a system of accelerated trains of inter-regional traffic, subject to the abolition of stops at separate points, which give a slight accumulation of passenger traffic. The paper proposes approaches to reducing the time spent by passengers on the road when traveling in interregional traffic. Reducing the passage time of a passenger train can be provided in two ways: as a result of organizational and technical measures, such as the temporary cancellation of stops at separate points, which give a slight accumulation of passenger traffic and as a result of modernization of permanent devices, which, if necessary, includes and rebuild. The reasons limiting the speed of movement at the railway station are revealed and analyzed. As a result of the cancellation of stops at separate points, the operating costs associated with the additional mechanical work of rolling stock in the process of acceleration, deceleration and parking will be reduced; expenses connected with delay of passengers on the way in the train; but on the other hand, the costs of additional waiting and passage of passengers residing at the stopping point will be increased. To solve the problem, a mathematical model for the scheme of stopping of accelerated trains of interregional communication was developed. To solve, that is, to identify possible stops in a small number of permissible solutions, it is possible to use a method of perforation with a constraint that provides a rigorous approach. The application of this method is based on the following: the criterion, in which the overall effect is taken, weakens the property of addiction, as well as a relatively small number of possible solutions (given the fact that a certain number of stops persists, as well as the fact that achieving a given time reduction the course of canceling one stop is not provided, and at least four or five, the number of possible solutions is further reduced). Stopping points at which stops are canceled are selected based on the maximum effect due to cancellation of the stop, as well as the possibility of modernization of permanent stopping devices.
