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 low desired velocities, small structures become relevant (composed by less than 5 pedestrians), but at intermediate velocities ($v_d\simeq 3\mathrm{m∕s}$) the pedestrians involved in the blockings increases (not exceeding 15 pedestrians).

我们在社会力量模型的背景下研究了房间疏散问题。我们着重研究了由225名行人在不同焦虑水平下逃离房间的系统，并分析了堵塞延迟是造成疏散性能的重要因素。我们将延迟与集群现象联系在一起，速度越慢，速度越快，机制越快。我们将证明，越快越快的政权的特征是存在着巨大的集群结构（由15个以上的行人组成），尽管在该政权内没有出现持久的延误。对于这个系统，我们发现更快的相关结构更慢制度是那些以某种方式附着在界定出口的两堵墙上的阻挡簇。在较低的期望速度下，小型结构变得有意义（由少于5个行人组成），但在中等速度下（$v_d\simeq 3\mathrm{∕}$）参与封锁的行人数量有所增加（不超过15名行人）。
