Efficient pedestrian evacuation in public areas is vital especially during large events like the Olympics. Placing obstacle can be one solution because some studies showed that setting an obstacle before the exit can improve the efficiency. However, this idea is controversial due to other opposite experimental results. Reflecting on the controversy, I would propose generalized influencing mechanism of obstacle.To be specific, depending on the match of obstacle layout and pedestrian conflict level, the obstacle influence has three phases that correspond to lower, stable and higher evacuation efficiency. The three phases will be validated by experiments and reproduced by modeling and simulation. Results will be used to evaluate and improve obstacle design for higher evacuation efficiency.

公共区域高效的行人疏散至关重要，特别是在奥运会这样的大型活动期间。设置障碍可以是一种解决方案，因为一些研究表明，在退出之前设置障碍可以提高效率。然而，由于其他相反的实验结果，这一想法存在争议。针对这一争议，笔者提出了障碍物的广义影响机制，具体而言，根据障碍物布局与行人冲突程度的匹配程度，障碍物影响可分为低疏散效率、稳定疏散效率和较高疏散效率三个阶段。这三个阶段将通过实验进行验证，并通过建模和仿真重现。结果将被用于评估和改进障碍设计，以提高疏散效率。
