In order to improve the efficiency of crowd evacuation in high-rise buildings in emergencies and reduce the risk of stampede caused by stair congestion, the difference between single and two-way flow evacuation modes of stairs was compared and analyzed. The quantitative evaluation of specific evacuation modes was carried out by using the advanced simulation software Massmotion to fill the research gap in the dynamic simulation of stairway evacuation. Based on the complex evacuation simulation model built by software, the single and two way flow evacuation under different stairway widths and different number of people were analyzed in detail. The experimental results show that the evacuation efficiency is higher when the slope is from 22.5° to 28.0°. When the number of people on the stairs is greater than 60, the efficiency of random evacuation is higher. The evacuation time of double running and double folding is longer, and it is not suitable to be used as a dredging channel. The way of queue evacuation is more reasonable for two-way flow.
