Abstract: Taking the intercity travel of Zhanjiang city as the research object, the spatial behavior characteristics of intercity travel of coastal cities residents are discussed from the microcosmic point through the questionnaire survey of passengers. The results show that, ①there are "point-axis" and "patch-channel" spatial distribution patterns of intercity travel of residents’ behavior in Zhanjiang. ②the Exploratory structural equation modeling (ESEM) of 5 variable model has better fitness; and latent factors model of 3 traffic modes (highway, railway and aviation) can be generally named as convenience, economy, comfort, safety and travel preference. ③ judging from the composition of observed variables and the load of identical latent variables in the latent factors model, residents behavior characteristics of different transportation modes differ obviously. ④Age, monthly income and the average number of monthly leaving from Zhanjiang city are important covariates that affect inter-city travel behavior. The research provides a theoretical support for the human-oriented planning of transportation sites and facilities, the composition optimizing of transport system, and the capacity enhancing of transportation services.
