疏散现象的微观动力学
Microscopic dynamics of the evacuation phenomena
摘要：
我们在社会力量模型的背景下研究了房间疏散问题。我们专注于一个系统的225名行人逃离一个房间，在不同的焦虑水平，并分析了堵塞延误的相关幅度负责疏散性能。我们将延迟与集群化现象联系起来，沿着“更快更慢”和“更快更快”的制度。我们将证明，“越快越快”制度的特征是存在巨大的集群结构（由超过15名行人组成），尽管该制度中不会出现长时间的延误。对于这个系统，我们发现，在“更快更慢”的制度的相关结构是那些阻塞集群，以某种方式连接到定义出口的两个墙壁。在非常低的期望速度下，非常小的结构变得相关（由少于5个行人组成），但是在中等速度（vd = 3 m/s）下，参与阻塞的行人增加（不超过15个行人）。
英文摘要：
We studied the room evacuation problem within the context of the Social Force Model. We focused on a system of 225 pedestrians escaping from a room in different anxiety levels, and analyzed the clogging delays as the relevant magnitude responsible for the evacuation performance. We linked the delays with the clusterization phenomenon along the "faster is slower" and the "faster is faster" regimes. We will show that the "faster is faster" regime is characterized by the presence of a giant cluster structure (composed by more than 15 pedestrians), although no long lasting delays appear within this regime. For this system, we found that the relevant structures in the "faster is slower" regime are those blocking clusters that are somehow attached to the two walls defining the exit. At very low desired velocities, very small structures become relevant (composed by less than 5 pedestrians), but at intermediate velocities (vd = 3 m/s) the pedestrians involved in the blockings increases (not exceeding 15 pedestrians).
