Development of Human Factors Guidelines for Advanced Traveler Information Systems and Commercial Vehicle Operations: Human Factors Evaluation of the Effectiveness of Multi-Modality Displays in ATIS

 

DEVELOPMENT OF HUMAN FACTORS GUIDELINES FOR ADVANCED
TRAVELER INFORMATION SYSTEMS AND COMMERCIAL VEHICLE OPERATIONS

HUMAN FACTORS EVALUATION OF THE EFFECTIVENESS OF MULTI–MODALITY
DISPLAYS IN ADVANCED TRAVELER INFORMATION SYSTEMS

 

FOREWORD

This is one in a series of reports produced as part of a contract designed to develop precise, detailed human factors design guidelines for Advanced Traveler Information Systems (ATIS) and Commercial Vehicle Operations (CVO). During the analytic phase of the project, research issues were identified and rated by eight human factors experts along fourteen separate criteria. The goal of the experimental phase was to examine the highest rated research issues that can be addressed within the scope of the project. The fourteen experiments produced in that phase reflect the results of those ratings.

This experiment examined the design issue of which display modality (i.e. visual, auditory, or multi–modality) resulted in the best driving performance. Effects of driver age, driving load, and information complexity were evaluated.

16. Abstract

To achieve the goals for Advanced Traveler Information Systems (ATIS), significant information will necessarily be provided to the driver. A primary ATIS design issue is the display modality (i.e. visual, auditory, or the combination) selected for providing this information. There were two objectives for this research. First, to what degree, and under which circumstances, are multi–modality displays beneficial? Second, for circumstances where multi–modality are not beneficial, which single display modality results in best performance? A simulator experiment was conducted to determine the effects of driver age, display modality, driving load, and information complexity on driving performance, navigation performance, driver workload, and driver performance.Four primary findings from the study were that:

  • For emergency response displays, the multi–modality and the auditory displays resulted in faster reaction times than the visual display for detecting warning information, while information presented on the multi–modality display resulted in fewer errors than the auditory display.

  • For navigation tasks, the multi–modality display resulted in the best performance for both total correct turns and number of navigation–related errors.

For driving performance, the multi–modality display generally resulted in better performance for both speed maintenance and safe driving behavior.

For subjective workload and preference ratings, the multi–modality display and the auditory display received more preferable ratings than did the visual display.
