三种类型的不同的步行行为（右偏好，一致性，空间优先）考虑到模型的双向行人流的通道与细胞自动机制定。根据仿真结果，得到了双向行人流、双向行人流和双向行人流的基本图，分析了这些行为对双向流动的影响。在相同密度条件下，非行人流的临界密度最小，非行人流的临界密度最大，而非行人流的平均速度高于其他两种类型的行人流。进一步，通过研究行人在通道内的分布情况和不能移动到前单元的行人比例，分析了导致这三种类型行人流不同特征的原因。此外，基于BehaviorSearch的仿真实验设计，以探索行人流量中的最佳比例的行人，行人和行人。实验结果表明，使行人流平均速度最大的条件不是行人流中只有一种行人，而是以行人为主、行人和行人混合的行人流。
Three types of different walking behaviors (right preference, conformity, and space priority) are taken into account to model bi-directional pedestrian flow in the channel with cellular-automata formulation. The fundamental diagrams of -pedestrian flow, -pedestrian flow, and -pedestrian flow are obtained from the simulation result to analyze the effect of these behaviors on bi-direction flow. The -pedestrian flow has the minimum critical density and -pedestrian flow has the highest, while the -pedestrian flow has higher average-speed than other two types of pedestrian flow under the same density. Further, through the study of pedestrian distribution in the channel and the proportion of pedestrians not able to move to the front cell, reasons leading to different characteristics of these three types of pedestrian flow are analyzed. Moreover, the simulation experiment based on BehaviorSearch is designed to explore the optimal percentages of -pedestrian, -pedestrian, and -pedestrian in pedestrian flow. The result of the experiment shows that the condition that makes the highest average speed of pedestrian flow is not that pedestrian flow consists of purely one type of pedestrians, but pedestrian flow mixed with -pedestrians as majority and -pedestrians and -pedestrians as minority.
