摘要:

社会群体对行人动态的影响,特别是在疏散场景中,最近引起了一些兴趣。然而,由于缺乏可靠的经验数据,大多数研究集中在建模方面。研究表明,社会群体可以产生相当大的影响,例如对疏散时间的影响。为了检验模型的预测,我们进行了实验室实验的疏散与不同类型和规模的社会群体。这些实验是在不同年龄的学生中进行的。已被考虑的参数是(1)组的大小,(2)组内相互作用的强度,(3)组的组成(年轻人,儿童和混合)。对于所有实验,使用PeTrack软件获得了所有参与者的高质量轨迹。这样就可以对群体效应进行详细的分析。一个令人惊讶的观察结果是随着组大小的增加,疏散时间减少。

英文摘要:

The effects of social groups on pedestrian dynamics, especially in evacuation scenarios, have attracted some interest recently. However, due to the lack of reliable empirical data, most of the studies focussed on modelling aspects. It was shown that social groups can have a considerable effect, e.g. on evacuation times. In order to test the model predictions we have performed laboratory experiments of evacuations with different types and sizes of the social groups. The experiments have been performed with pupils of different ages. Parameters that have been considered are (1) group size, (2) strength of intra-group interactions, and (3) composition of the groups (young adults, children, and mixtures). For all the experiments high-quality trajectories for all participants have been obtained using the PeTrack software. This allows for a detailed analysis of the group effects. One surprising observation is a decrease of the evacuation time with increasing group size.
