Research conclusions: Through the analysis of technical features and passenger flow of the main traffic modes within Mianyang-Chengdu-Leshan corridor, the connection mode should be established for the different transport modes. In order to fully play the function and benefit of intercity railway, the following two points should be considered for the connecting intercity railway with other traffic modes in corridor; passenger transfer connection and transport organization connection for obtaining the aims of sharing and rational usage of resource. The station location of intercity railway should be selected according to the layout of urban rail transit planning, existing public transportation, bus stop and airport. The intercity railway station should be closed to urban rail transit station, bus stop, coach station and airport as much as possible. The study of traffic integration should be done well so that the intercity railway passenger can take urban public transportation easily and the peak passenger flow of intercity railway bypassed.
