Abstract How reliable must traffic information be for motorists to trust and accept such advice? This study provides data to aid the designer of Advanced Traveler Information Systems (ATIS) in selecting an appropriate level of system accuracy. The Battelle Route Guidance Simulator was used to study: (1) the effects of information accuracy, and (2) familiarity of the driving environment on objective and subjective indices of driver performance and opinion. The simulator provided real-time information and traffic video. Information was either 100%, 71%, or 43% accurate. Drivers experienced either Seattle and its environs or an artificial setting that was topologically matched to Seattle. Results showed that while 100% accurate information yielded best driver performance and subjective opinion, information that was 71% accurate was still accepted and used. But information that was 43% accurate produced powerful decrements in performance and opinion. Simulated ATIS information was not used as effectively in the familiar Seattle setting. Driver trust decreased with inaccurate information but recovered, although not always fully, with subsequent accurate information. References, 1 table, 9 figures.
