论文摘要
我们在社会力量模型的背景下研究了房间疏散问题。我们专注于一个由225名行人组成的系统，这些系统以不同的焦虑水平逃离房间，并将堵塞延迟分析为负责疏散性能的相关程度。我们将延迟与沿“更快的速度更慢”的聚类现象联系起来，“更快的速度更快”。我们将证明“更快的速度更快”的制度的特征是存在巨大的集群结构（由15个行人组成），尽管在这个制度内没有出现持久的延迟。对于此系统，我们发现“更快的速度更慢”的相关结构是那些以某种方式连接到定义出口的两个墙壁上的阻止群集。在非常低的速度下，非常小的结构变得相关（由少于5人组成），但是在中间速度（VD = 3 m/s）下，参与阻塞的行人增加（不超过15人行人）。
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).
