Summary
This 1998 cross-cutting study, prepared by Booz·Allen & Hamilton for the Federal Highway Administration, synthesizes findings from multiple Field Operational Tests (FOTs) of Advanced Traveler Information Systems (ATIS). The research addresses the need to evaluate the efficacy, user acceptance, and implementation challenges of traveler information technologies in real-world settings. By analyzing data from over a dozen distinct FOTs—including Atlanta Kiosk, Genesis, Seattle Wide-Area Information For Travelers (SWIFT), and ADVANCE—the report aims to extract common lessons learned to guide future ITS deployment. The study categorizes findings into impacts, user response, technical performance, institutional challenges, and implementation costs. The methodology involved a comparative analysis of existing FOT reports and evaluation data rather than new primary data collection. The tests covered a wide range of technologies, including pre-trip systems (kiosks, pagers, PDAs) and en-route systems (in-vehicle navigation, FM-subcarrier broadcasts, Variable Message Signs). Specific tests examined dynamic route guidance, transit information integration, and weather warning systems in diverse environments, from urban centers like Atlanta and Seattle to rural areas in Idaho and Colorado. The analysis focused on how these systems influenced traveler behavior, technical reliability, and the institutional frameworks required for public-private partnerships. Key findings indicate that both pre-trip and en-route information generally yielded positive impacts. Pre-trip data increased driver confidence in using freeways and improved transit decision-making, while en-route guidance saved travel time and helped avoid congestion. Users responded positively to portable, easy-to-use pre-trip devices and valued en-route voice-direction systems for their safety and efficiency. However, many users remained unaware of ATIS availability, and while commercial users reacted favorably, many private users did not alter their travel behavior despite receiving route choices. Technically, pre-trip systems using existing configurations performed well after initial data integration issues were resolved. In contrast, en-route technologies varied significantly; in-vehicle devices and PCs functioned as intended, though some personal communication devices suffered from poor readability, and prototype systems exhibited developmental instability. The study highlights significant institutional challenges, particularly regarding legal liabilities, copyright protection, and the formation of effective public-private partnerships. Differing views on partnership structures often hindered progress. Regarding costs, while data was somewhat outdated, users expressed a willingness to pay for services they perceived as valuable. The report concludes that while ATIS technologies offer tangible benefits in traffic management and traveler convenience, successful deployment requires resolving institutional barriers, ensuring technical robustness in en-route devices, and increasing public awareness to drive adoption.
Key finding
Pre-trip information increased driver confidence to use freeways and improved transit choices, while en-route guidance saved travel time and helped travelers avoid congestion.
