Abstract:

City exchange center (CEC) is an emerging transportation hub infrastructure that provides comprehensive services such as parking, public transit transfers, and business entities, thus enhancing public transit patronage and developing green and smart mobility systems. This study is designed to explore the complex relationships among single-mode, multimodal, auto, transit, and nonmotorized trips considering the characteristics of urban multimodal trips with the CEC in operation to describe the residents' travel mode choice based on the cross-nested logit model. Combined with the data of the stated preference survey in Xiongan New District, we find that a public transit system is a key entry point for improving the CEC transportation service level. Travelers choosing higher-level services are more sensitive to time and less sensitive to costs, while travelers choosing lower-level services show the opposite behavior; therefore, it is necessary to survey the population distribution and household income level in the early stage of CEC construction. The waiting time of travelers should be controlled to within 10 min. The reduction of waiting time is meaningless to the improvement of travel service if it exceeds the threshold. This study explores the influencing factors for residents' travel mode choice and will be helpful for CEC planning schemes, providing quantitative guidance for other urban areas to improve public transport.
