摘　　要：在现有公交网络模型的基础上,建立了一种新的多重边公交线路网络模型.这种公交线路网络模型以公交线路为节点,公交线路间的若干个相同停靠站点为连边.同时根据网络拆分的思想,对具有相同站点的三条不同的公交线路,通过引入时滞,将四重边公交线路网络拆分为四个性质不同的子网络,进而以Chen系统为网络的节点,研究了四重边复杂公交网络的全局同步.改变公交车辆之间的控制强度和相同的站点个数,分析了公交车辆的人为调度和线路优化对公交线路网络平衡的影响.最后通过Matlab进行数值仿真,为城市公交网络的合理调度提供理论依据.This paper develops a new public traffic network model with multi-links based on the existing public traffic network model. The model takes bus lines as the network nodes, and the same bus stops as the network links. Based on the concept of network split, the paper divides the complex public traffic network with multi-links into four different sub-networks for three public bus routes with time-delay. Then taking＂Chen system＂as the network node, the paper studies the globalsynchronization of the four-links complex network. Changing control degrees and the same bus stops number of some public transport vehicles, the paper analyses the impact of bus dispatching and bus lines optimization to the public traffic network balance.At last, numerical simulation is conducted by Matlab. This research provides theory basis for the reasonable dispatch of urban public traffic network.
