Applying the TAM to travelers' usage intentions of GPS devices

Research highlights? This study investigates factors affecting travelers' usage intention of in-vehicle GPS products. ? The moderating effect of personal innovativeness on the relationship between attitude and behavioral intention is examined. ? Attitude to in-vehicle GPS products is the most significant factor influencing travelers' usage intention. This study investigated factors affecting travelers' usage intentions of in-vehicle GPS products and examined the moderating effect of personal innovativeness on the relationship between attitude and behavior intention. Based upon technology acceptance model (TAM) and unique features of GPS devices, a self-administered questionnaire was designed and used to collect empirical data. The results obtained from hierarchical regressions revealed that (1) perceived ease of use has a significant positive effect on perceived usefulness; (2) all perceived usefulness, perceived enjoyment and perceived ease of use have significant positive effects on attitude toward usage; (3) attitude toward usage has also a significant positive effect on behavior intention, and (4) personal innovativeness is found to moderate the relationship between attitude and behavior intention. The implications of findings were discussed.
