Abstract
In this study, a driving simulator is integrated with a traffic simulator at the network-level for the first time to allow subjects to drive in a fairly realistic environment and at a realistic traffic flow and density. A 3.1×3.1 mi2 (5×5 km2) network was developed in a driving simulator and then exported to a traffic simulator. About 30 subjects drove the simulator under different traffic and driving conditions and variable message sign (VMS) information with and without the integration of a traffic simulator. Route guidance was available for the subjects. The study concluded that traffic density and VMS reliability is higher when driving simulator and traffic simulator are integrated, however, subjects' route choice and route diversion behavior was similar. A binary logistic regression model was utilized to find factors affecting route diversion. The results indicated that the original chosen route, displayed VMS information, subjects' attitude toward VMS information helpfulness, and their level of exposure to VMS affects route diversion.
