What Counts in the Bus Use for Commuting? A Probe Survey Based on Extended Theory of Planned Behavior

Abstract

In order to lead people to pro-environmental transportation modes, it is necessary to learn about the psychology and behavior of users. Based on the extended theory of planned behavior-incorporating habit, descriptive norm and personal norm, this paper analyzes the relationship between these elements and intention to use bus, and the influence of habit on intention-behavior. The result of survey conducted in Chengdu City reveals different outcomes from previous study, especially for the attitude and perceived behavior control. In addition, the intention to use bus and habit can explain 41.7 % variance of the bus use ratio to the total travel. However, the interaction of habit and intention is insignificant.
