Determination of minimum level of available carrying capacity of sections where the effective use of connected train formation and driving technology is possible

Abstract

Periods of section work are established when using the connected train driving technology (CT), which does not depend on the level of section loads yminload. In other cases, efficiency of the CT technology depends on the effect produced by increasing carrying capacity. Minimum level of load yminload, if possible, is determined by the amount of traffic, for which delays of trains start when approaching to the sections. To determine the value yminload, a method of statistical simulation of train operation is developed (Monte Carlo method). Train flow dimensions are determined due to the fact that daily distribution can be described by a normal distribution law. Exceeding the daily amount of traffic as compared with available carrying capacity of sections allows determining the number of delayed trains on the way to the section. A computer program is developed; mass calculations are made for the average amount of traffic from 40 to 100 freight trains per day. The obtained value yminload equals to 0.8. This value may be applied at the practical work of JSC RZD when using the connected train driving technology.
