Abstract: In order to study the dynamic characteristics of urban public traffic network, this paper presents a new public traffic networks based on the existing public traffic network model. The paper analyzes the community structure of public traffic networks based on the clique percolation method. Then taking Lorenz system as the network node, the paper studies the synchronization of the public traffic networks with community structure. By changing control degrees, deleting the ordinary bus lines and critical bus lines, the paper investigates the synchronization of the new network model. Finally, numerical results are given to show the impact of bus dispatching and bus lines optimization to the public traffic network stability through Matlab simulation.

摘要： 为了研究城市公共交通网络的动态特征，在现有公交网络模型的基础上，建立了一类新的复杂公交网络模型。同时基于派系过滤算法，对复杂公交网络模型进行了社团结构分析。以Lorenz系统为网络的节点，研究了复杂公交社团网络的同步问题。通过改变公交车辆之间的控制强度、删除网络中普通公交线路和关键公交线路，研究了公交社团网络的同步问题。采用Matlab仿真技术分析了公交车辆的人为调度和线路优化对公交线路网络稳定性的影响。
