To explore the effects of different types of route information on freewaydrivers’ enroute switching behavior, this paper used two stage research methods.First, this paper applied “Structural Equation Modeling (SEM)” to verify thelatent variables that will positively or negatively affect drivers’ enroute switchingintention and explore the causal effect between them. “Ordered ProbitModel (OPM)” method was then used to confirm whether latent variables andtypes of route information will affect drivers’ enroute switching behavior in thestated congestion scenarios. According to the case study, the research subjectswere freeway drivers traveling between Keelung and Hsinchu City. 493 validquestionnaires were collected. The results of SEM showed that all research hypotheseshave been confirmed. The drivers’ enroute switching intentions werenegatively impeded by the drivers’ tolerance of congestion and perceivedswitching barriers. Therefore, providing more applicable route information contentsin terms of drivers’ opinions must be taken into great consideration. Theobserved results reveal that drivers’ enroute switching behavior would be motivatedby providing more detailed information on alternative routes. The improvementof the route information contents may help the traffic managementagency to implement congestion management strategies. |
