Based on what the previous studies did before, the researchers carry out human experiments to analyze the process of evacuation and the optimization of obstacles settings, thus providing theoretical support to improve the efficiency of evacuation in a panic situation. The experimental videos provides us peculiar phenomena during the evacuation, for instance, three individuals crowding together can block the exit and the evacuation process seems to be periodically fluctuated. By comparing experiments differentiated by the obstacle settings, the paper concludes that a reasonable placement of obstacles can improve the efficiency of evacuation, and that setting two obstacles is better than one. Furthermore, crowding is partly alleviated by the placement of obstacles, so that the evacuation process could become more stable, more orderly, thereby the efficiency of the evacuation is better.
