Application of the Theory of Planned Behavior to the Analysis of Variations in Attitudes toward Exclusive Motorcycle Lanes

Abstract

The purpose of this paper was to test the differences in attitudes influencing motorcyclists' behavioural expressions of motorcycle lane use as classified by demographic data and attitude factors from an application of the Theory of Planned Behaviour (TPB) comprised of four factors: Attitude toward use, Subjective norms, perceived behavior control, and Behaviour intention. A questionnaire study of 1,004 motorcyclists in Nakhon Ratchasima province was conducted. Independent t-tests, One-Way ANOVA were used to analyze differences between motorcyclists' demographic data and components in the Theory of Planned Behavior. The findings revealed that different age groups and income levels had significantly different effects on perceived behavior control and behavior intention to use motorcycle lanes. While there were considerable differences in indications of attitude toward use and perceived norms across educational levels. Furthermore, perceived behavior control and behavior intention differed significantly across urban and rural areas, including driver's license status. Differences in location zone subjective norms, as well as attitudes toward the use of different driver's license statuses
