| Summary | In the past, studies on drivers’ route switching behavior intentions did not discuss the effects of drivers’ acceptance of real-time traffic information and switching barriers. We used a two-stage research methodology to explore the effects of real-time traffic information on freeway drivers’ switching behavior intentions. First, Exploratory Factor Analysis (EFA) method was applied to identify measurable variables in order to extract key latent variables. Then we applied Structural Equation Modeling (SEM) to confirm these variables that affect drivers’ route switching intentions and to explore the causal effect between them. A relationship model for explaining drivers’ switching behavior intentions was established and verified. The questionnaire data used in this study were randomly collected from drivers traveling between Keelung and Hsinchu City in order to explore the drivers’ acceptance of real-time traffic information, switching barriers, and their route switching intentions. The results of this study show that the relationship between these variables and all the hypotheses we made have been confirmed. The main variables which significantly and positively affect drivers’ switching behavior intentions are the perceived value and usage attitude of real-time information, while switching barriers negatively affect drivers’ switching behavior intentions. This study also provides traffic management suggestions about the content of real-time traffic information offered to drivers for traffic management agencies. |
