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 sable components of ITS
