Foreword

FOREWORD

This report is one of a series 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). The contractual effort consists of three phases: analytic, empirical, and integration. This report is a product of the analytic phase. Among the other analytic topics discussed in the series are ATIS and CVO system objectives and performance requirements, functional description of ATIS/CVO, comparable systems analysis, task analysis of ATIS/CVO functions, alternate systems analysis, and identification and exploration of driver acceptance.

This report documents the systematic definition and prioritization of human factors research issues related to the implementation of in-vehicle ATIS and CVO systems.

16. Abstract The goal of the activities documented in this report was to produce a prioritized list of candidate studies and issues that would guide data acquisition in this project. This goal was accomplished in three steps. First, 91 issues were compiled from earlier research in this effort. Second, a set of 14 criteria, 9 substantive and 5 methodological, were defined. Eight experienced human factors experts completed all 2,184 cells in a rating matrix for a total of 17,472 rating entries in the data set. Third, a linear psychometric model was used to prioritize the 91 issues. The model was validated by sending the raters three short prioritized lists, one of which was (unknown to the raters) a stratified random sample of studies and issues. Raters were asked to delete unimportant and impractical research issues from these lists. They deleted significantly more items from the random list. The nine most vital studies/issues from the final prioritized list are: cognitive demands in transitioning across ATIS functions, complex interactions among ATIS functions, how ISIS and IVSAWS information influences behavior, effects of low information reliability, displaying multiple messages, features requiring standardization, single versus multiple display channels, multimodal displays, and effects of display modality and format on CVO driver workload. The key human factors issues listed here must be address to assure in-vehicle information systems are a safe and usable components of ITS.
