The Analysis and Optimization of Urban Transit Network Based on Complex Networks

In this paper, we propose an approach for constructing the weights of edges in urban transit networks based on complex networks. Jinan City is taken as an example in this paper. At first, the undirected and unweighted network composed of bus stops and bus lines is constructed respectively, the static characteristics and transfer characteristic of transit networks are analyzed, and the robustness of the network is analyzed by means of random attack and intentional attack. In the second part, the weight of edges are assigned by the approach we proposed. Finally, we propose a method to optimize the structure of the bus network.
