About the research
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 (RPMs), both raised and recessed, for nighttime driving, particularly during wet weather.
See the NCHRP project page for more information.
