Pedestrians are often encountered walking in the company of some social relations, rather than alone. The social groups thus formed, in variable proportions depending on the context, are not randomly organised but exhibit distinct features, such as the well-known tendency of 3-member groups to be arranged in a V-shape. The existence of group structures is thus likely to impact the collective dynamics of the crowd, possibly in a critical way when emergency situations are considered. After turning a blind eye to these group aspects for years, endeavours to model groups in crowd simulation software have thrived in the past decades. This fairly short review opens on a description of their empirical characteristics and their impact on the global flow. Then, it aims to offer a pedagogical discussion of the main strategies to model such groups, within different types of models, in order to provide guidance for prospective modellers.

行人人群中的社会群体:回顾他们对动态及其建模的影响

行人经常遇到一些社会关系的陪伴,而不是单独行走。这样形成的社会群体,根据上下文以不同的比例组成,不是随机组织的,而是表现出鲜明的特征,例如众所周知的 3 人群体呈 V 形排列的趋势。因此,群体结构的存在可能会影响人群的集体动态,在考虑紧急情况时可能会以一种关键的方式影响。在多年来对这些群体方面视而不见之后,在人群模拟软件中对群体建模的努力在过去几十年里蓬勃发展。这篇相当简短的评论首先描述了它们的经验特征及其对全球流动的影响。然后,它旨在提供对此类群体建模的主要策略的教学讨论,
