Abstract: Based on a large number of surveys of air passengers in Beijing Capital International Airport, this paper quantitatively analyzes 4340 valid questionnaires by the models of structural similarity coefficient, multiple logistic regression, logit model, and concludes travelling-preference mechanism and the characteristics of air passengers. The passengers in Beijing prefer long distance trips to short distance trips whose selections of the way of travelling have the spatial feature of“short distance trips by vehicles and long distance trips by air flights” and development tendency of“increasing preference of air flights while decreasing preference of ground transportation”. With respect to four factors affecting passengers’travelling: costs, time, comfort level and flexibility, according to passengers’decision-making mechanism and the supplies structure, passengers select the ways of travelling on the basis of the similarity coefficient between passenger demand structure and traffic supply structure. In accordance with logistic regression model of passengers’travelling intention, education level and income positively affect“time value of passengers”,“proportion by plane”and“frequency by plane”of travelers. According to microcosmic demand and supply analysis model of passenger travelling, air flight is the primary priority of business travelers in Beijing, followed by bullet train; holiday travelers prefer air flight and then bullet train, travelers who are visiting relatives and friends tend to choose long distance coach or drive by themselves; most of students travel by train and long distance coach. Based on time value and utility function, this paper concludes the distribution rate of passengers in the new airport is about 41.2%.
