Development of the Questionnaire of Bus Drivers’ Road Traffic Violations Based on Extended Theory of Planned Behavior

The research on road traffic under the theory of planned behavior is increasing in China. However, in the field of public transportation, especially the research on the road traffic violations of bus drivers is relatively limited. In this study, the questionnaire about bus drivers’ red-light running behavior was developed based on the theory of planned behavior (TPB), and its reliability and validity were tested. This questionnaire was designed with questions of different dimensions based on the extended theory of planned behavior. There were two sample groups in this study. Exploratory factor analysis was conducted with sample 1, and confirmatory factor analysis and reliability analysis were conducted with sample 2. The research results show that the questionnaire developed for measuring the red-light running behavior of bus drivers based on TPB theory has good structural validity and internal consistency and reliability, which meets the requirements of psychological measurement. The results provide theoretical reference for the study of road traffic violations of bus drivers in China.
