【摘要】：斜坡通道中双向行人流的行为动态是研究人群安全疏散的基础.人群密度增加时,行人之间的挤压、冲突作用均增强,加之,斜坡倾角越大,行人行走的稳定性越差,易引发推挤倒地的安全隐患.本文建立斜坡通道中双向行人流的势函数场元胞自动机模型,考虑行人之间作用力和通道倾斜度影响.该模型用于模拟行人流动态和倒地现象.模拟结果得出:当通道坡度、行人入流密度增加时,上坡人群的倒地概率达40%,而下坡人群的倒地概率高达60%.在此基础上,考虑到我国行人偏向右边行走的习惯,以及人群的跟随效应,通过划分两个方向人群的入流位置,将两向行人流分为两股互不干扰的行人流,从而解决行人之间的挤压与冲突,并通过模拟验证该策略可避免倒地现象发生.
[Abstract]:The behavior dynamics of two-way passenger flow in ramp passage is the basis of studying the safe evacuation of people. With the increase of crowd density, the compaction and conflict between pedestrians are strengthened. In addition, the greater slope inclination, the worse the stability of pedestrian walking, which can easily lead to the safety hidden danger of pushing and collapsing. In this paper, a potential function field cellular automaton model of two-way passenger flow in ramp passage is established, which takes into account the influence of pedestrian force and channel inclination. The model is used to simulate the movement of people and landfall. The simulation results show that when the channel slope and pedestrian inflow density increase, the probability of downhill is up to 40 and that of downhill is as high as 60. On this basis, considering the habit of walking to the right of pedestrians in our country and the following effect of the crowd, the two-direction pedestrian flow is divided into two streams of non-interference pedestrian flow by dividing the inflow position of the two directions of the crowd. In order to solve the extrusion and conflict between pedestrians, and through simulation to verify that the strategy can avoid the phenomenon of falling to the ground.
