Safety and Performance Criteria for Retroreflective Pavement Markers

The objective of this research is to develop a guide for transportation practitioners that describes and evaluates the safety benefits, as shown by driver performance or other methods, of Retroreflective Pavement Markers (RPM), both raised and recessed, for nighttime driving, particularly during wet weather. The guide should address criteria and information for use and placement of RPMs which may include, but not be limited to the following: (1) 2-lane rural, urban multi-lane, limited access, and other roads in urban and rural areas (2) Tangent and horizontal curve sections (3) Use of RPMs in conjunction with other types of roadway delineation devices, roadway surface treatments, and lighting and their impacts on driver performance (4) The visibility needs of drivers, particularly those 60 years of age or older (5) Various types of RPMs, i.e., recessed, raised, snow-plowable, etc. (6) Development of performance measures and minimum RPM performance level
