Pavement markings are the most common traffic control device (TCD) used to communicate roadway information to drivers. To be effective, they must convey information in all lighting and weather conditions. As a result, pavement markings on public roads contain retroreflective elements, such as glass beads, so that light from vehicle headlights is returned to the eye of the driver at night.
The TRB National Cooperative Highway Research Program's NCHRP Research Report 1015: Performance Criteria for Retroreflective Pavement Markers seeks to isolate and identify the effects of retroreflective pavement markers (RPMs) from a cohesive, three-pronged investigation of driver visibility, behavior, and safety.
