Fluorescent Orange Retroreflective Raised Pavement Marker Color Recognition Study

Retroreflective raised pavement markers (RRPMs) provide a significant amount of information for nighttime drivers, especially during inclement weather. Unfortunately, RRPMs are essentially designed for nighttime conditions only, as they are nearly impossible to see during daytime conditions. However, recent innovations in the traffic control device industry have resulted in the introduction of fluorescent properties into the design of RRPMs. The introduction of fluorescent coloring of RRPMs is potentially a revolution in terms of adding daytime delineation to the roadway. Another advantage of adding fluorescent coloring to RRPMs is the ability to create new colors of RRPMs that have not been previously developed or tested. For instance, fluorescent orange RRPMs can be made to match the color of fluorescent orange signing used in work zones. Before fluorescent orange RRPMs can be used on a widespread basis, two aspects need to be resolved. The first is to determine whether drivers can correctly distinguish the color of the fluorescent orange RRPMs from traditional RRPM colors. The second aspect is to identify the most effective application(s) of fluorescent orange RRPMs. This paper addresses the first of these two issues.
