Red light running by young motorcyclists: Factors and beliefs influencing intentions and behavior

บทคัดย่อ (ABSTRACT)
Traffic violations by young riders are major safety problems in motorcycledominated countries. This study investigates young motorcyclist’s red light running (RLR) intentions and behavior based on the Theory of Planned Behavior (TPB) framework. Behavioral, normative, and control beliefs underlying rider’s RLR are identified. Young riders (N?=?246) complete a TPB questionnaire measuring direct and beliefs-based measurement items. The exploratory factor analysis technique reveals factors according to TPB. Structural Equation Modeling (SEM) results show moderate to good fits to the observed data and provide qualified support for the utility of TPB in explaining traffic violation behavior. The findings reveal that perceived norm and attitude dominate violation intentions. Beliefs about normative referents and negative outcomes affect RLR intentions. Intentions affect behavior, especially when riders lack of perceived autonomy. Rider’s degree of control is affected by the beliefs about facilitating circumstances and weather conditions. Besides, perceived autonomy and perceived capacity each influence violation intention and behavior independently. Implications for young motorcyclist safety interventions based on current findings are discussed.
