Verify the Interactive Coercing Relationship Between Rail Transit and Bus

It is of great significance to promote the coordinated development and collaborative operation of regular bus and rail transit so as to improve the operational efficiency of urban public transport system for the sustainable development of urban traffic. Based on the theory of interaction coercion between urbanization level and eco-environment, this paper constructs the theoretical model of interaction coercion between rail transit and ground bus, and takes 10 cities that have opened operational rail transit in China in 2009 as the study sample, collects 10 cities from 2010 to 2019, including Wuhan, Tianjin, Dalian, Changchun, Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing and Chongqing. Based on the annual passenger flow data of regular bus and rail transit, this paper studies the variation of passenger flow between rail transit and regular bus to verify the possibility of interaction coercion between rail transit and regular bus. The results show that there is an interactive coercive relationship between urban rail transit and regular bus, and the evolution path conforms to the biexponential function. The development of urban rail transit shows a significant coercive effect on regular bus, while the development of regular bus shows a significant constraint on rail transit.
