通道中障碍物布局对行人运动影响的多格子模型研究

传统行人疏散运动模型对障碍物环境下的个体运动行为关注不足,而且未较好地讨论不同障碍物布局下的行人运动特性。通过改进多格子模型建立了考虑障碍物布局影响的行人运动模型,并与实验结果对比验证了该模型的有效性。利用该模型对不同障碍物布局下的单、双行人流进行模拟,探究不同障碍物布局对行人运动的影响。模拟结果表明,合理的障碍物布局有助于提高行人流的运动速度。丰富了传统多格子模型在障碍物环境下的运动规则,能够为行人交通设施设计及科学管理提供理论与技术支持。

A modified multi-grid model for studying the effect of obstacle layouts on pedestrian flow in corridors

The influence of different obstacle layouts on pedestrian flow in corridors has not been well investigated in models. A modified multi-grid model is established to explore the influence of obstacle layout in this paper, and the model is well validated by experiments. Then, we study the effect of three obstacle layouts on unidirectional and bidirectional pedestrian flow by the improved model. Simulation results demonstrate that the effect of obstacle layouts on pedestrian movement in the corridor is significant. The modified multi-grid model proposed in this paper enriches and improves pedestrian movement rules, so that it can be adapted to describe pedestrian movement in obstacle environment. The research provides a technical support and theoretical basis for the design and management of pedestrian walking facilities.
