Abstract
This study proposes an extension of the theory of planned behavior (TPB) to investigate whether psychological factors can potentially be predictors for the behavioral intention of private car use in future work trips. The study sample comprised 156 undergraduate students who were in their senior year and were expected to graduate in the next few months. A questionnaire survey was conducted to measure several psychological variables related to private car use for future work trips after graduation. Core constructs included subjective norm, attitude, and perceived behavioral control, with an addition of moral obligation. Based on structural equation modeling, subjective norm, attitude, and moral obligation were found to be significant determinants for the behavioral intention. Contrary to the TPB, the perceived behavioral control was not found to be a statistically significant factor influencing the intention of private car use in future work trips. Practical implementations of the results are discussed.
