目前对行人动力学的研究主要集中在孤立个体之间的相互作用，没有充分考虑群体存在的影响。近5年来，研究人员开始对行人群体运动进行研究。本研究的目的是通过问卷调查和实地观察来探讨步行群体的本地行为。调查研究侧重于行人群体行走时的心理，包括群体规模、人际距离、群体成员之间的空间关系、群体成员的速度调整、信息传递和群体成员之间的酸作用五个部分。同时对群体运动特征进行了实地观察，包括速度、步进频率、偏移角度和人际距离。调查结果显示，群体成员之间的人际距离更近，信息传递速度更快，酸性作用更强。相反，与孤立步行相比，群体步行对行人的速度、步频有负向影响。此外，研究发现，对于某一群体，群体成员能够保持一致的运动。由于性别和社会关系的不同，不同群体类型（男性群体、女性群体、情侣群体和普通朋友群体）之间也存在明显的运动差异。最终，这些结果将更有希望帮助模拟行人群体的运动。(c) 2014 Wiley期刊公司中文信息学报20 (2):87-97,2015
Current research on pedestrian dynamics mainly focuses on the interactions among isolated individuals, the impact of the presence of groups is not fully considered. In recent 5 years, researchers have started to investigate pedestrian group movement. The aim of this work is to explore the local behavior of pedestrian groups by questionnaires and field observation. Survey study focused on pedestrians' psychology when walking in groups, which included five parts: group size, interpersonal distance, spatial relationship among group members, speed adjustment of group members, information transmission, and acid action among group members. Meantime a field observation was carried out to study group movement characteristics, which contained speed, step frequency, offset angle and interpersonal distance. The survey results show that group members have a closer interpersonal distance, faster information transmission and plenty of acid action. Conversely, group walking has a negative influence on pedestrian's speed, step frequency by comparing with the way isolated pedestrian walks. In addition, it is found that for a certain group, the group members are able to keep movement consistent. Also there exists obvious movement diversity among different group types (male dyads, female dyads, couple groups, and ordinary-friend groups) because of different gender and social relationship. Ultimately the results will be more promising for helping to model the movement of pedestrian groups. (c) 2014 Wiley Periodicals, Inc. Complexity 20: 87-97, 2015
