论文摘要
在本文中，我们设计了一个微观（基于代理的）数学模型，用于在特定情况下重现人群行为：许多行人，由许多社交群体组成，沿着走廊流动，直到位于走廊尽头的大门关闭。人们没有被告知关闭大门，而是感知到当地人群状况的动态观察的阻塞。一旦人们意识到新条件，他们就会停下来，然后决定留下来，等待重新开放，或者回去永远离开走廊。人们对尚未意识到堵塞或已经决定留下的新来的人们进行了击败。这会产生一个危险的柜台流，很容易导致事故。我们运行了几个数值模拟，这些数值模拟改变了控制人群行为的参数，以了解对动态影响最大的因素。我们以一些针对大众事件组织者的有用建议结束。
In this paper we devise a microscopic (agent-based) mathematical model for reproducing crowd behaviour in a specific scenario: a number of pedestrians, consisting of numerous social groups, flow along a corridor until a gate located at the end of the corridor closes. People are not informed about the closure of the gate and perceive the blockage observing dynamically the local crowd conditions. Once people become aware of the new conditions, they stop and then decide either to stay, waiting for reopening, or to go back and leave the corridor for ever. People going back hit against newly incoming people who are not yet aware of the blockage or have already decided to stay. This creates a dangerous counter-flow which can easily lead to accidents. We run several numerical simulations varying parameters which control the crowd behaviour, in order to understand the factors which have the greatest impact on the dynamics. We conclude with some useful suggestions directed to the organizers of mass events.
