It is the common responsibility of the whole society to provide friendly and appropriate help for disabled tourists.However, the altruistic behavior of ordinary tourists towards disabled tourists has been ignored in academia, and few studies have focused on the internal factors that affect the altruistic behavior of ordinary tourists. To fill in these gaps, planning to investigate 500 respondents, based on The Tri-component attitude model, this study, applying SEM, will examine the effect of ordinary tourists' perceived level of information about the travel barriers faced by physical disabled tourists on their empathy and discomfort, which positively affected their altruistic behavior intention to physical disabledtourists. Moreover, the contents of ordinary tourists' perceived level of information and information source will be explored through 10 in-depth interviews. Theoretical and practical implications of this research were discussed as well.
