Book excerpt: This report details the first year of a two-year project. During the first year the emphasis was on determining the wet-night visibility of various pavement marking systems under a variety of realistic rainfall levels. The researchers performed a literature review. They analyzed 20 years of Texas rainfall data to determine the most appropriate rainfall levels to use as design criteria for a rain tunnel. Using a low, medium, and high rainfall rate (0.28, 0.52, and 0.87 in. per hour, respectively), a 1600 ft long rain tunnel was designed and built at Texas A & M University's Riverside Campus. Experimental subjects drove through the rain tunnel and looked for pavement markings simulating skip lines. The researchers rotated pavement marking samples at different locations before each trial. The detection distance was recorded when the subject located the pavement marking sample. The data were analyzed in four main sections: waterborne paints, thermoplastics, tapes, and exotic materials. The analysis also included investigations into the wet-night visibility of rumble stripes, as well as wider lines. The measured dry and wet retroreflectivity measurements were analyzed, and the predictive capabilities of the wet retroreflectivity measurements were evaluated with respect to the wet-night detection distance of the markings.

This book was released on 1996 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the night visibility of waffle tape and paint with large beads, particularly during wet night conditions. Data were collected at two sites along a primary arterial. The evaluation included an examination of (1) the application of the markings, (2) the visibility of the markings using retroreflectometer measurements and subjective assessments, and (3) the costeffectiveness of the markings. The study revealed: (1) compared with paint with standard beads, the waffle tape and paint with large beads were slightly more retroreflective during light rain at night and recovered quicker after flooding out, (2) the marginal improvement in visibility during periods of light rain do not offset the operational problems of applying paint with large beads, and (3) the benefits of waffle tape during light rain do not appear to justify its use solely for wet night visibility. Because of the above findings, snowplowable raised pavement markers, which are very visible in wet night conditions, appear to be more cost-effective. The study recommends that (1) VDOT continue to use and maimain snowplowable raised pavement markers for visibility during wet night conditions, (2) VDOT continue to monitor FHWA's study on all weather pavement markings, and (3) the Suffolk District consider testing nonsnowplowable raised pavement markers to assess their use as a low-cost alternative to improve visibility during wet night conditions where snowplowing occurs infrequently.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
