为了缓解大型客运航站楼行人穿行在时间和空间上造成的冲突和拥堵，提出了延伸穿行区的新概念。采用基于地面场考虑行人行走习惯的元胞自动机模型。在MATLAB环境下进行数值模拟，探讨四组行人通过不同设置的编织区走到四个出口时的清空时间与瓶颈设置之间的关系。研究发现，采用改进的扩展编织区设置，可以在时间和空间上缓解编织区的应力；从而提高行人通行效率。在仿真的基础上，本文还给出了扩展编织区域中单个瓶颈宽度的阈值。
A new concept called the extended weaving area is proposed to relieve the conflicts and clogging caused by pedestrian weaving in both time and space in large passenger terminal. The cellular automaton model that considers pedestrian walking habits based on the floor field is adopted. Numerical simulations are carried out in MATLAB environment to explore the relationship between the emptying time and bottleneck setting when four groups of pedestrians walk to four exits through the weaving areas with different settings. It is found that, by using improved extended weaving area settings, the stress of the weaving area could be relieved in both time and space; thus the efficiency of pedestrians passing could be improved. Based on the simulation, the threshold of single bottleneck width in the extended weaving area is also given in this research.
