本文係第一次以控制體積模式作車站避難時間計算，將避難人群視為流體進行分析，求得每一時間的控制表面變化。由於人是不具重疊的特質，避難人群滯留面積則可得知。另以控制體積理論求得車站內在不同出口流率、車廂內人數、候車人數等因素下滯留人數，滯留人數、滯留面時責與時間的關係式的數值結果，並進行討論與比較。

This paper is the first literature related to evacuation of the transit station by control volume model. All of the varieties of the control surface of the evacuee are determined by means of dynamic fluid. The area of the control surface is determined by assuming that people do not the property of the accumulation. Using the control volume method, the different factor of the flowing rate, crowd people number and waiting people versus times for the evacuation are determined and discussed.
