Abstract:

This study is part of the evaluation of the FAST-TRAC operational test of an Intelligent Transportation System (ITS) in Michigan and is concerned with user perceptions and behaviors with Advanced Traveler Information Systems (ATIS). The use and perceptions of 60 subjects, of both sexes and three age groups (19-to-29, 30-to-64, and 65-to-80), who drove a project vehicle equipped with a TetraStar navigation assistance unit for one month in normal everyday conditions are reported. The same subjects had earlier driven test vehicles equipped with Ali-Scout, another ATIS navigation device, for one month. Subjects kept daily trip logs and completed a detailed survey about their uses, perceptions, and valuation of the TetraStar system and about comparison of this system against the Ali-Scout. Overall, drivers liked the attributes and performance of the TetraStar system and rated them highly. Only the freeway ramp method of selecting destinations received consistently negative assessments. There were few significant differences in the use and perceptions of this system by sex and age group. However, men were more likely than women to want more navigation information, to be more distracted by the system and to want more advanced warning. Drivers in the oldest age group had greater problems in learning and using TetraStar. On average, subjects were willing to pay about $500 for this system in a new car, $350 to add it to their present car, and about $8.50 per day to have it in a rental car. Overwhelmingly, subjects preferred TetraStar over Ali-Scout, reporting that it provided more accurate route guidance and was easier to use and program.
