Abstract

Several criteria for traffic sign symbols were examined through a questionnaire survey that allowed determination of the importance, or weighting, that should be assigned to each symbol in the design and evaluation of signs. The survey sample included traffic sign experts (members of national traffic control device committees) and practicing traffic engineers from Australia, New Zealand, Canada, and the United States. Separate ratings were assembled for symbols in general and for warning, regulatory, and information symbols in particular. Understandability was the factor rated most important, with conspicuity second. Learnability was considered least important, while reaction time, legibility distance, and glance legibility were rated equally but were determined to be more important than learnability.
