论文摘要
这项研究探讨了在“公牛竞选”节日期间紧急撤离的动态（西班牙，2013年）。当人们逃避危险时，许多行人跌跌撞撞地摔倒了，而其他行人会试图越过它们。我们仔细检查了跑步的三个特定记录，这些记录显示了这种行为。我们开发了一个微观模型，模仿了社会力量模型（SFM）的背景下的绊脚石。在我们的模型中，当“移动”个体在堕落者附近时，他们可以突然转变为“堕落”状态。我们得出的结论是，堕落的行人的存在显着增加了附近行人的可能性下降。同样，局部密度梯度和每个行人速度之间的产物似乎是即将跌落的相关指标。我们将其称为行人“降低的敏感性（F_S）”。
This research explores the dynamics of the emergency evacuation during the "Running of the Bulls" festival (Spain, 2013). As people run to escape from danger, many pedestrians stumble and fall down, while others will try to pass over them. We carefully examined three specific recordings of the running, that show this kind of behavior. We developed a microscopic model mimicking the stumbling mechanism in the context of the Social Force Model (SFM). In our model, "moving" individuals can suddenly switch to a "fallen" state when they are in the vicinity of a fallen individual. We arrived to the conclusion that the presence of a fallen pedestrian increases dramatically the falling probability of the pedestrians nearby. Also, the product between the local density gradient and the velocity of each pedestrian appears as a relevant indicator for an imminent fall. We call this the pedestrian "falling susceptibility (f_s)".
