Abstract: [Purposes] To explore the law of multi-mode travel in hub areas of mountainous cities is significant to the formulation of transportation strategies under the integrated development of station and city.[Methods] Talking Chongqing East Station as the research object,the MNL travel choice model was constructed based on the data of weekday peak hours,and the traffic operation characteristics under mountainous terrain were analyzed,and compaction by VISSIM simulation.[Findings] The study reveals the cost-sensitive characteristics of multimodal travel in mountainous city hubs,reflects the roleof dense road network structure in promoting slow travel,and verifiesthedecision-making logic of walking substitution when community buses are insufficient.[Conclusions] The "comprehensive cost optimization" prediction framework is proposed,and the model accuracy is improved through RP survey and dynamic OD iterations,which providesquantitative supports forcoordinating rail transit and non-motorized travel systems and optimizing thereliabilityof mountain road networks,and has practical values for the coordinated development of stations and cities.
