人群聚集是行人群体中的一种普遍现象，对人群行为有重要影响。群组建模仍然是一个具有挑战性的开放问题，尚未被现有的群组模拟模型所包含。从群体建模对人群行为模拟的需要出发，提出了一种统一的、定义良好的行人群体轮胎结构建模框架。同时考虑了组内结构和组间关系，并对它们对群体行为的影响进行了建模。在此框架基础上，开发了一个基于智能体的人群仿真系统，并给出了两种不同群体结构下的人群行为仿真。仿真结果表明，该框架可以方便地对不同的群体结构进行建模。此外，不同的群体规模、群体内部结构和群体间关系也会对群体行为产生显著影响。(C)2009爱思唯尔B.V.保留所有权利。
Grouping is a common phenomenon in pedestrian crowds and plays important roles ill affecting crowd behavior. Group modeling is still an open challenging problem and has not been incorporated by existing crowd Simulation models. Motivated by the need of group modeling for crowd behavior simulation, this paper presents a unified and well-defined framework for modeling tire structure aspect of different groups in pedestrian crowds. Both intra-group structure and inter-group relationships are considered and their effects on the crowd behavior are modeled. Based on this framework, an agent-based crowd Simulation system is developed and crowd behavior simulations using two different group structures are presented. The simulation results show that the developed framework allows different group structures to be easily modeled. Besides, different group sizes, intragroup structures and inter-group relationships can have significant impacts oil crowd behaviors. (C) 2009 Elsevier B.V. All rights reserved.
