In accordance with the actual situation that the traditional bus scheduling is difficult to guarantee the optimal operational efficiency, and on the basis of the internal operating mechanism of the urban spatial structure and the transport system, the network model of urban public transport is constructed. The simultaneous theory of the time-varying delay nonlinear coupling equation of the same node N is used to make the public transport scheduling network achieve the asymptotic stability, that is, to make the whole bus lines reach a dynamic equilibrium state. The dispatching method can obtain the dynamic equilibrium of the whole public traffic system, thus to get a dynamic scheduling. Some bus lines in Lanzhou public traffic system are taken as an example to show the effectiveness of the model and the method.%针对传统方法优化公交调度难以保证运营效率达到最优的实际情况,基于城市空间结构与交通系统的内在运行机制,构造城市公交网络模型,利用N个等同节点的时变时滞非线性耦合状态方程的同步理论,使公交调度网络系统达到渐进稳定,即各线路乘客流量达到一种动态平衡.该调度方法能使整个公交系统达到动态平衡以实现"动态"调度,以兰州市公交网络系统的部分公交线路为例,验证了该模型及方法的有效性.
