摘　　要：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,构造了城市公交网络模型,利用N个等同节点的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,即各线路乘客达到一种均衡状态。以兰州市公交系统的部分线路为例,验证了该模型及方法的有效性。Aimed af seeking an alternative to the conventional way which fails to ensure bus scheduling with optimal operational efficiency, this paper deals with the development of the urban public trans-port scheduling network model, based on the urban spatial structure and the transport system of internal operating mechanisms. The paper introduces the use of the nonlinear simultaneous equation of the cou- pling state by the same node N to realize the asymptotic stability of the entire public transport scheduling network, namely an equilibrium state available for the passengers of the whole bus lines. The paper high-lights the part of bus systems which verifies the optional routes of the traveling and the effectiveness of transfer in Lanzhou.
