城市公交网络连通满意度指标研究

Research on Satisfaction Index of Urban Public Transport Network Connectivity

公交网络的连通性是评价公交服务能力的重要指标。从公交出行者的角度提出新的方法,度量出行者对于公交网络连通性的满意程度。以矩阵形式表达公交站点间的拓扑连接关系,并以网络中具有连接关系的站点对作为研究对象,使用公交车载GPS数据确定不同时段站点间运行的公交线路出行效率,以出行者对公交出行效率的最低期望作为阈值判定站点间的连通状态。通过分析提出城市公交网络连通满意度指标,为评价城市公交网络服务水平提供参考。

The connectivity of bus networks is the main index for evaluating the capacity of bus service.This paper presents a new method from the perspective of bus passengers to measure the traveler’s satisfaction with the bus network connectivity.The topological connection relation between bus stations is established through the matrix form,and the topologically connected station pair in network is taken as the research object,bus GPS data is used to calculate the travel efficiency of bus lines running between stations in different periods,and the minimum expectation of the traveler for the efficiency of bus travel is used as the threshold to judge the connectivity between stations.Through the analysis,this paper proposes the satisfaction index of urban public transport network connectivity,which provides reference for evaluating the service level of urban public transport network.
