Research on Internal Static Accessibility Evaluation of Urban Rail Transit Network

The topological structure of urban rail transit network directly determines the degree of difficulty of passenger transfer in the transit system. To evaluate the degree, we defined the internal static accessibility of urban rail transit network as the indicator. We then proposed specific methods to establish a dual-topology map for an urban rail transit network and to use the matrix for describing the connection relationships between transit lines within a network. Accordingly, we put forward our internal static accessibility assessment indicators and carried out case studies of rail networks in Shanghai. The proposed description method of the network topological structure and evaluating indicator of ISA of the URTN provided quantitative analysis tools for the evaluation, selection and optimization of network planning schemes.
