Fluorescent Strong Yellow-Green Signs for Pedestrian/School/Bicycle Crossings:Results of a New York State Study

摘要

The investigation was conducted as part of FHWA's nationwide study to evaluate anew sign color known as 'fluorescent strong yellow-green' (SYG) for use at pedestrian, school, and bicycle crossings. The new color is highly visible and is proposed as more effective than standard yellow signs. The report presents results of SYG sign tests at three sites in New York State. At each site a single 'before' and 'after' study was designed--the 'before' study was conducted with standard yellow signs and the 'after' with fluorescent SYG signs. The studies concerned traffic volume, driver behavior, and vehicle speed. An 'impression' survey of persons viewing the signs was also conducted. Results of these studies and responses from the survey provided encouraging evidence of the benefits of using SYG signs over standard signs, although the short duration of this study and limited number of sites do not allow strong recommendations.
