Abstract: The metro becomes an integral vehicle of modern city transportation. As the specificity of the operating environment of the metro, under accident conditions it extremely leads to the problem of personal safe evacuation of the metro station. The inland platform metro station in Xi’an as the research object, this paper uses the Building Exodus software to simulate safe evacuation from personnel composition, the quantity of entrances and exits, the width of the stairs and the situation of fire, establishes the metro station model to simulate the evacuation time in each situation, then compares with the results calculated by the formula from “code for design of metro”. The simulation results truly reflect the influence of various factors on the evacuation capacity of the station. It draws a conclusion that the design of the stairs is a bottleneck for the entire evacuation process, furthermore makes relevant recommendations.
