Abstract

Current and revised versions of the Advance Flagger traffic sign were compared in a series of pilot studies. Comprehension, reaction time, glance legibility and preference of each of the signs were tested through both field and laboratory tests. In field tests of Advance Flagger signs, approximately 86% of subjects gave construction-related responses to both new and current Advance Flagger signs. In lab tests, significant differences were found between the new and current signs in both glance legibility and reaction time. The findings suggest the new version to be an improvement over the current design.Relevance to industryThis paper relates to the transportation industry. Motorists depend on the traffic signs to guide, warn and regulate them as they travel the highways during daylight, darkness, and inclement weather conditions. Improvements in traffic signing has one of the highest benefit-cost ratios for highway safety improvements.
