为了研究城市公共交通网络的动态特征,本文在现有公交网络模型的基础上,运用space P方法和space R方法分别建立了公交换乘网络和公交线路网络.然后将这两个网络作为子网络,并通过换乘网络中停靠站点和线路网络中的公交线路之间的联系构建了一类新的双层耦合公交网络模型.该模型能够很好地反映出行乘客与公交运营车辆之间的联系.基于耦合网络的同步理论,以非线性Lorenz系统为网络的节点,研究了双层耦合公交网络的同步问题.最后,采用Matlab仿真技术分析了公交运营中的人为调度、公交线路之间公共停靠站点的数目,以及站点之间的可达性对双层耦合公交网络平衡的影响.
In order to study the dynamic characteristics of urban public traffic network,this paper establishes the transfer network and bus lines network by respectively using the method of space P and space R based on the existing public traffic network model. Then regard these two networks as the sub-network,a new two layers public traffic coupled network is presented through the connection between the bus stops and bus lines,and this model can well reflect the connection between the passengers and bus operating vehicles.Based on the synchronization theory of coupling network and taking"Lorenz system"as the network node,the paper studies the synchronization of two layers public traffic coupled network. Finally,numerical results are given to show the impact of public traffic dispatching,the number of common bus stops between bus lines and the accessibility between bus stops to the two layers public traffic coupled network balance through Matlab simulation.
