Interaction of a structure and a partially controlled traffic current

The problem of interaction of a structure and a traffic current underlies the problems of calculation and improvement of railway stations. For a long time the rated traffic current was presented as the average multiplied by the irregularity coefficient. Then the interaction was described by means of the queuing theory. The real traffic currents are nonrandom, they are partially controlled. The article examines the fundamental principles of the interaction of the mixed traffic current and a structure.
Key words: traffic current, structure, random, controlled, interaction
