GUIDELINES FOR EVALUATING FLUORESCENT STRONG YELLOW GREEN CROSSING SIGNS

The manual was prepared to assist States and local highway agencies in conducting field studies to determine the effects of fluorescent strong yellow green crossing signs on motorist behavior at pedestrian, bicycle, and school crossings. These guidelines were developed to utilize existing personnel and equipment with a modest time expenditure. A before and after study with comparison site experimental design is recommended for the effectiveness evaluation. Field data collection using two observers and readily available inexpensive equipment is suggested. Included in the manual are guidelines for selecting study sites, collecting the field data, and conducting the analysis.
