Recently, underground spaces are developed to heighten the utilization rate of city. However, these spaces exist dangerous in fire situation. So it is necessary to study for evacuation safety design of the subway station. The purpose of this study is to compare on evacuation simulation tool of subway station disaster. The study carried out two different simulations on the subway station plan. The results were divided into two groups by using SIMULEX, EXODUS. According to result of (1) when SIMULEX and EXODUS were both in same condition, there wasn't really big difference. People used the shortest way to refuge. (2) Bottleneck effects occurred in same position in both programs and they were underground floor stairways and gates. Those are the positions where opening's width gets smaller. (3) In subway fire accidents, even though there are lots of people in the subway, people's reaction rate seems to not affect refuge rate much. It was all because of bottleneck effect. (4)EXODUS's Avoid Population Density function shows that simulation result is way more reliable than familiarity, wall proximity, reaction rate, loitering, incitement and variables. (5) Evacuation simulations are way more reliable when lots of different kinds of evacuation minds are used.
