Summary
This report addresses the critical issue of user acceptance for Advanced Traveler Information Systems (ATIS) and Commercial Vehicle Operations (CVO), components of Intelligent Transportation Systems. Motivated by historical precedents where new technologies, such as automatic teller machines, failed to achieve widespread adoption, the study aims to develop precise human factors design guidelines. The research seeks to identify the specific features drivers find desirable, understand the factors influencing their trust in automated systems, and propose a model for predicting driver acceptance of in-vehicle information technologies. The study employed a mixed-methods approach comprising three distinct empirical experiments. Experiments 1 and 1B utilized questionnaire-based surveys to assess driver preferences for two hypothetical systems: "TravTek," focused on route guidance, and "CityGuide," focused on urban navigation and recreational information. These experiments analyzed feature desirability, ease of use, and perceived usefulness across different demographic groups, particularly examining age and gender. Experiment 2 used a route guidance simulator that presented real-time video of driving scenes alongside a map interface. In this simulation, participants could purchase traffic information with varying degrees of accuracy (including a condition where information was only 77% accurate) to determine how information reliability and cost influenced driver behavior, trust, and route selection. Experiment 3 focused on commercial vehicle operators, using magnitude estimation and paired comparison tasks to evaluate feature preferences for CVO systems. The findings revealed that drivers accepted ATIS information even when its accuracy was limited to 77%, indicating a high tolerance for imperfect data provided the system offered perceived utility. In the questionnaire studies, specific feature patterns emerged as highly desirable, including basic map displays, voice guidance, and coordination of travel information. The simulator results demonstrated that drivers’ trust in the route guidance system was significantly influenced by the accuracy of the information and their prior experience with the system. Older drivers exhibited different patterns of trust and self-confidence compared to younger drivers, often relying more heavily on purchased information. For commercial vehicle operations, the study identified distinct feature priorities for local versus long-haul drivers, providing tentative recommendations for tailoring CVO systems to these specific user groups. The significance of this work lies in its contribution to the development of human factors guidelines for ITS. By establishing a tentative model for driver acceptance, the report provides actionable insights for designing ATIS and CVO systems that align with user expectations and behaviors. The findings suggest that successful implementation requires not only technical accuracy but also careful consideration of interface design, information presentation, and user education. The study underscores the importance of understanding psychological factors, such as trust and self-confidence, in promoting the adoption of advanced transportation technologies, thereby offering a framework for future research and system development in the field of intelligent transportation.
