Capacity of metro station elements as a function of human traffic density

The object of research is turnstiles and escalators of subway stations. The work aims to obtain dependence of turnstile and escalator capacity on human traffic density and to determine the maximum values of the capacity of escalators and turnstiles in the operational mode of the station. Method. To obtain the values of throughput capacities, experimental studies were conducted on observations of incoming passengers at loaded stations of St. Petersburg subway during the peak hours of station The experimental data were processed using the least squares method (second-order polynomial model). Results. Mathematical dependences of turnstiles and escalators capacity on human traffic density were obtained. It was established that the maximum escalator capacity for ascent in the operational mode of the station is 5500 people/hour, for descent - 4200 people/hour. The maximum turnstile capacity at the operational mode of the station is 1430 people/hour. It was found that the Russian regulatory base overestimates the escalator capacity by 33.5% and underestimates the turnstile capacity by 43%.
