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.
