Field Evaluation of Fluorescent Strong Yellow-Green Pedestrian Warning Signs

Recent improvements in manufacturing processes have allowed the development of a fluorescent, microprismatic sign material with a unique strong yellow-green color. Although this color is listed in the Manual on Uniform Traffic Control Devices, it is currently unassigned. Pedestrian accidents continue to be a major safety problem in the United States, and the Federal Highway Administration has requested research on the application of fluorescent strong yellow-green warning signs for pedestrian, bicycle, and school crossing applications. The research effort sought to evaluate the effectiveness of fluorescent strong yellow-green pedestrian warning signs in improving safety at midblock pedestrian crossing areas, using sound experimental methodology and encompassing multiple users and varied crossing conditions in several North Carolina cities. An experimental plan with a single treatment was used (replacement of existing signs with fluorescent strong yellow-green) and followed a model of before and after with...
