This paper analyzed passenger transport features and passenger behavior at different locations of the escalators and studied the factors affecting the actual through capabilities of the escalators in subway station by doing field surveys about technical characteristics and passenger transport characteristics of typical escalators in subway station. On the basis of existing research results, this paper presented a way based on applying queuing theory to calculate the actual capabilities of the escalators in subway station, and verified its legitimacy.
