TY - JOUR PY - 1990// TI - Visibility distance of highway signs among young, middle-aged, and older observers: icons are better than text JO - Human factors A1 - Kline, Theresa J. Babbitt A1 - Ghali, Laura M. A1 - Kline, Donald W. A1 - Brown, Steven SP - 609 EP - 619 VL - 32 IS - 5 N2 - The visibility distances for young, middle-aged, and elderly observers of text and icon versions of four different highway signs were compared under day and dusk lighting conditions. No age differences were observed. Icon signs, however, were visible at much greater distances than were text signs for all three age groups, a difference that was more pronounced under dusk conditions. There were no age differences in the comprehension of icon signs, but there was considerable variability from one icon sign to another in the degree to which they were comprehended. Acuity was found to be a better predictor of the visibility distance of text signs in both day and dusk conditions than it was of icon signs. To the degree that they are comprehended, icon signs appear to offer drivers of all ages almost twice as much time in which to respond to them.
