Abstract: Passenger transport corridor connects major cities and transport hubs, which is the material base of social and economic development. Based on topological structure and space form features of integrated transport network, this paper focuses on structure development of Pearl River Delta passenger transport corridors. The research reveals that railway is the most efficient mode, and road transport possesses the best robustness. The changing of passenger transport corridors results from the interaction between short-term existence effect and long-term existence effect. The coverage intensity of road and railway network are respectively 1.495 and 1.050. The development of railway network is relatively lagged behind other modes, which needs more efforts to strengthen. Moreover, transport network connectivity will increase three times after railway network extending, resulting high connectivity of cities. Meanwhile, standard entropy of railway transport network will get a 4.48%increase; network coverage of railway transport will increase by 36.19%, and the structure of passenger transport corridor will be improved significantly.
