The first year report contains the literature review on wet-night markings and the Phase I effort on wet-night pavement markings. This report contains the Phase II effort on wet-night pavement markings, a benefit-cost analysis, and a study of contrast markings. Phase II effort consisted of expanding the study design from Phase I to include additional wet-night pavement marking products, the effects of glare and dry pavement on detection distances, and a benefit-cost analysis with respect to the use of different pavement marking systems to accommodate drivers under wet-night conditions. In the contrast study, a literature review of contrast markings, a state-of-the-practice with respect to contrast markings, and a study of driver understanding and preference with respect to contrast markings were all conducted. After studying multiple wet-night pavement marking products and standard pavement marking products used in the state of Texas, it was found that reflectorized raised pavement markings provided the most preview time under wet-night conditions.This report details the completion of a 30-month project investigating wet-night and contrast pavement markings.
