This article describes a virtual reality role-playing game that was developed as a survey tool to collect travel behavior data and explore and monitor travel behavior adaptation. The Advanced Energy and Material Systems Laboratory has designed, developed a prototype, and tested such a game platform survey tool, called Travel Activity Constraint Adaptation Simulation (TACA SIM). A main objective is investigating adaptability under the simulated situation of rapid fuel price. The computer game survey approach has the potential to capture real behavior data through a well-controlled experiment, because the participant experiences the survey as a role-play exploration. Feedback from participants confirms that TACA SIM collects data efficiently in an acceptable time while the participants enjoyed the experience. The authors propose that this gamed-based survey approach provides the basis for collecting and evaluating travel behavior data and adaptation behavior. (Contains 1 table and 9 figures.)
