Research on the Choice Behavior of Intercity Travel Mode for Middle and Long Distance Based on SEM-Logit Model

This article investigates long-distance intercity travel and studies inter-city travel under different factors. Travel intention selection mechanism. The questionnaire survey includes factors such as personal social attributes, travel characteristics, transportation mode, and service characteristics, and also incorporates potential variables such as reliability, comfort, convenient, and economy. Based on the maximum utility theory and behavior decision theory, the structural equation model and the SEM-logit integrated model of the three modes of travel of high-speed rail/motor train, ordinary train, and aircraft were established. The relationship between different latent variables was analyzed. The research results show that the SEM-logit model with latent variables added has a good model interpretation result by improving the traditional multiple logit model. At the same time, it also shows that travelers are not only the result of some single factors in the intercity travel decision process, but many cross-influencing factors also have an important influence on travel decisions.
