Coordination of the Last Train in Urban Rail Transit Based on Complex Network

The coordination of the last train in the urban rail network is an important evaluation index for the management and operational service. Based on the complex network, we propose an approach to calculate the coordination of the last train in the urban rail network according to the actual published timetable. Firstly, the adjacency matrix is built where the elements shows the coordination situation of last trains. In the constructed network, the nodes represent the transfer stations while the links indicate the connective between two transfer stations. Then, we analyze network characteristic parameters (degree, shortest path, proportion of coordination, etc.). The proposed approach provides a quantitative evaluation model and a new viewpoint for the issue of coordination of the last train in the urban rail network.
