研究机场人流优化疏散问题,由于机场内人流和滞留旅客量大,进行行人行为建模得出行人活动规律,是进行人员疏散、维护公共安全的基础。针对机场的空间特点,研究人员采用势能场方法对行人行为建模,通过目的地和障碍物等对行人的影响来确定行人的总势能。同时采用精细网格模型对特定区域进行行人行为仿真。仿真结果表明,在变截面空间的运动中,行人在低密度情况下可不受截面变化影响。对于高密度情况,行人会受到相互干扰,以被迫改变自己的运动轨迹。研究给出了相关行人轨迹,为疏散提供参考。
To study the problem of evacuation in airport flow optimization, pedestrian behavior modeling is based on the large number of pedestrians and stranded passengers in the airport. It is the basis for evacuation of personnel and maintenance of public safety. According to the spatial characteristics of the airport, the researchers used the potential field method to model pedestrian behavior and determined the total potential energy of pedestrians through the influence of pedestrians such as destination and obstacles. At the same time, the fine grid model is used to simulate pedestrian behavior in a specific area. The simulation results show that the pedestrian can not be affected by the change of section under the condition of low density in the movement of the variable section space. For high-density situations, pedestrians can be disturbed and forced to change their trajectory. The research gives the relevant pedestrian trajectory, providing a reference for evacuation.
