Summary
This report presents a literature scan and best practices review regarding driver perspectives and expectations of Intelligent Transportation Systems (ITS), specifically Advanced Traveler Information Systems (ATIS). Sponsored by the Wisconsin Department of Transportation, the study addresses the critical need to understand driver acceptance to inform ITS deployment strategies. The motivation stems from the high costs, long lead times, and complex partnerships required for ITS mechanisms, which necessitate careful selection to avoid costly mistakes. The authors aimed to identify gaps in existing research and summarize best practices for delivering information to drivers effectively. The methodology involved a six-month process comprising a literature scan and interviews with agencies nationwide. The researchers identified 158 relevant articles, which were winnowed down to an annotated bibliography of 84 entries. This review analyzed existing studies on driver reactions to various ITS elements, focusing on market segmentation, technology preferences, and information utility. The study categorized drivers into "technophiles" (approximately 30% of commuters, typically young, male, and wealthy) who actively seek new technologies, and the "general public" who prefer low-hassle, existing media like radio, television, and Changeable Message Signs (CMS). Key findings indicate that drivers do not care about the ITS concept itself but value specific technologies that provide direct benefits. Existing media (radio, TV, CMS) are highly popular and satisfactory to 60–80% of commuters, yet they suffer from low usability and limited information content. In contrast, new-technology ATIS systems have low adoption rates due to high "hassle" factors, such as the need to actively seek information or press multiple buttons, which outweigh cost concerns. The report segments information demand by trip type: commuters and special trip travelers (e.g., airports, stadiums) exhibit high demand for information and low tolerance for delay, making them prime markets for ATIS. Truck drivers also show high demand but are skeptical of government implementation capabilities. Drivers consistently require five specific pieces of information to make route decisions: problem existence, nature, delay duration, prescribed alternate routes, and a comparison of alternative delays. The significance of this work lies in its recommendations for future research and deployment. The authors conclude that improving existing, low-hassle media like radio and CMS offers a powerful, low-cost tool for influencing driver behavior, potentially yielding higher diversion rates than new technologies. The report identifies significant research deficiencies in areas such as work zone ITS, special event needs, rural/intercity driver needs, and trucker requirements. It recommends prioritizing research into enhancing current information sources and addressing the specific needs of non-commuter markets to improve overall driver satisfaction and safety.
Key finding
Drivers prefer low-hassle existing media like radio and CMS over new technologies, with commuters and special trip travelers showing the highest demand for information and lowest tolerance for delay.
