The purpose of thestudy is to evaluate the safety effectiveness of severallow-cost safety improvement strategies through scientificallyrigorous crash-based studies.One of the strategies selected for evaluation for this studywas the application of wet-reflective pavement markings.This strategy involves upgrading existing markings fromstandard marking materials to wet-reflective markings,which may be applied as a paint, tape, or thermoplasticmaterial. These markings are designed to provide animproved level of retroreflectivity during wet road surfaceconditions
