Abstract
In order to improve the stability and efficiency of urban public transport system, the urban public transport network was studied based on the complex network theory. Taking Changchun City as an example, based on the Space L method, the weighted composite network model of Changchun City public transportation was constructed, and the statistical characteristics of network topology was analyzed; the index was selected to evaluate the network robustness. Composite networks are modularized by community detection algorithm. The research shows that the collectivization degree and stability of Changchun public transport complex network is poor; when the network is attacked randomly, it shows strong robustness, while when it is deliberately attacked, it shows strong vulnerability. Optimization suggestions was given from two aspects of intentional attack and random attack, the research results can provide a theoretical basis for the optimization of public transport network.
