摘要：	This report describes research on the durability and color recognition of flourescent orange signs. The evaluation focused on two primary activities: a comparison of the durability of fluorescent and non-fluorescent orange signs; and a comparison of the color recognition of flourescent orange, non-flourescent orange, and other sign colors. In the durability evaluation, damaged and undamaged products were exposed for 24 months on a weathering rack. The evaluation of the flourescent products included measurements with a new instrument that accurately measures the flourescent properties of fluorescent materials. Other measurements included retroreflectivity and color. In the color recognition evaluation, drivers were asked to identify the color of various stimuli as they drove on a closed course. The accuracy of color identification and the identification distance were recorded.
