Abstract: Taking the bus station as the node of dynamic network, the influence of vehicle distribution and passenger demand for bus stops on the balance of public transport network service was mixed to build the bus dynamic network model, which took the passengers’ total waiting time at stops as its edge weight. Then the corresponding relationship between bus network service and bus dynamic network structure was established. On this basis, the space and time balance of the dynamic network was set as the objective, and the network state recognition mechanism was built. Besides, the temporal and spatial variation rule of bus dynamic network was analyzed under the condition of peak passenger flow and flat peak. Finally, taking the time and space balance of dynamic network as the optimization goal, the ordinary line service frequency optimization model was established. Through the computation of case studies, it is found that the proposed model can obtain the optimal service frequency of ordinary line under the steady state network, which provides a new train of thought for the research of public transport scheduling.

摘要： 以公交站点作为动态 网络的节点，融合车辆分布与站点乘客需求对公交网络服务均衡性的影响，构建以站点乘客总等车时间为边权的公交动态网络模型，确立公交网络服务与 公交动态网络结构的对应关系。在此基础上，以动态网络的时空均衡性为目标，构建网络的状态识别机制，并分析了客流高峰、平峰条件下，公交动态网 络在时空上的变化规律。最后，以优化动态网络的时空均衡性为目标，建立普通线路发车频率优化模型。通过实例计算发现，该模型可以获取稳态网络目 标下普通线路的最优发车频率，为公交车辆调度的相关问题研究提供一种新的思路。
