Identification of Desired System Features in an Advanced Traveler Information System

This study evaluated consumer acceptance of variations of a currently available Advanced Traveler Information System (ATIS). We also wanted to determine if video demonstration was sufficient for observers to grasp the fundamentals of ATIS devices. A total of 109 licensed drivers viewed two videotaped demonstrations of TravTek, and then completed questionnaires. Principal Factor Analyses resulted in patterns of desired features and other composite variables used in regression analyses. Basic map features (e.g., vehicle position/location, outline of route) and voice features were the two dominant feature patterns. Other composite variables included understanding of the system capabilities, trust, self-confidence, tolerance of system errors, demonstration fidelity and attention. Results of the regression analyses indicated that different variables were significant predictors of each pattern of desired features.
