The purpose of this study was to evaluate the operational applicability of raised pavement markers and to determine their effectiveness with respect to brightness and durability. Seven different types of markers were evaluated. The primary application of markers in this study was as a supplement to lane lines. They were also used as a traffic control measure at lane drops, as delineation for hazardous curves, and as directional arrows. Luminousity and durability were monitored for approximately one year. It was found the raised pavement markers can be a very effective method of roadway delineation. Markers evaluated had varying levels of brightness and durability. Costs varied considerably among types. Specifications, which classified and described the markers, were proposed. Details for the recommended design layout of markers as supplements to and replacements for lane were proposed.
