研究行人团体的社交距离与渗透性，发现群体存在三种隐含区域。
Proxemics and Permeability of the Pedestrian Group
- 基于自然数据识别群体三类隐含空间区域
- 人群主要停留公共区，靠近群体行为罕见且短暂
- 揭示群体交互中的社会规范机制，适合城市交通研究者参考
人们常以群体形式行走，群体互动对人群行为与行人流动动力学有显著影响。社会规范可视为调节社交情境中人际互动的非正式规则。本文通过自然主义数据研究个体与群体的互动及群体近场（proxemics）的形成。分析显示除公共区外，群体可能存在三种不同区域。个体倾向于停留在公共区，仅以低频、短暂的方式逐步接近群体，表现出明显的空间边界与渗透限制。
原文摘要 · Abstract (English)
People tend to walk in groups, and interactions with those groups have a significant impact on crowd behavior and pedestrian traffic dynamics. Social norms can be seen as unwritten rules regulating people interactions in social settings. This article studies people interactions with groups and the emergence of group proxemics. Group zones, zone occupancy counts and people clearance from the group are studied using naturalistic data. Analysis indicate potential presence of three different zones in addition to the public zone. People tend to remain in the public zone and only progressively get closer to groups, and those closer approaches happen in a low frequency and for brief periods of time.
