Book Synopsis Pavement Marking Visibility Requirements During Wet Night Conditions by : Ronald Bruce Gibbons
Download or read book Pavement Marking Visibility Requirements During Wet Night Conditions written by Ronald Bruce Gibbons and published by . This book was released on 2006 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the performance of pavement markings in wet night conditions. Typically, performance will decrease in wet conditions. The degradation is a result of flooding of the marking optics and a change in the optical media, thereby reducing retroreflectivity and the visibility distance. Several technologies are available to improve the visibility of markings under wet conditions. This study used four technologies and evaluated them in a dynamic situation. In the experiment, vehicles were driven by older participants and visibility was measured based on the detection distances of the beginning or ending of a continuous edge marking. The results indicate that a specifically designed wet retroreflective tape performed better than the currently used paint and glass bead technology. Paint with large glass beads and profiled thermoplastics also showed an improvement over the standard paint and glass bead technology. A relationship between retroreflectivity and the detection distance was found, which was used to postulate a minimum required value for visibility during wet night conditions. A value of 200 mcd/m2/lx appears to provide a reasonable detection distance for a minimum performance requirement.

Available in PDF, EPUB and Kindle. Book excerpt: This executive summary describes an investigation into the performance of pavement markings in wet night conditions. The performance of a typical pavement marking will degrade when it gets wet. This is a result of the flooding of the marking optics, thereby reducing retroreflectivity. Several technologies are available to improve wet marking performance. In this project, six technologies were tested using both standard measurement methods and participant evaluations. The results show that two of the marking technologies, raised retroreflective markers and wet retroreflective tape, outperformed the group under all conditions. These markings were also highly accepted by the participants. The results also show that the standard paint and glass beads technology is the worst performing and the least desirable of those evaluated. A comparison of the ASTM retroreflectivity measurement methods and the measured luminance results also indicates that the methods are suitable for the conditions used in the evaluation; however, possible additions and corrections to the methods are outlined in this report. A follow-up study is underway to allow development of a performance-based specification for pavement markings for wet night visibility.

Available in PDF, EPUB and Kindle. Book excerpt: Transportation infrastructure systems serve as the platform for emerging automated vehicle (AV) technologies and, in their current condition, limit the reliability of these new vehicles. Road conditions, lane markings, and signs provide essential guidance and information to both human- and machine-controlled vehicles; however, their condition and placement vary depending on local conditions, practices, and funding. Irregular sign placements and road markings confuse both human and machine drivers and can create unsafe conditions. Still, in the short term, they are the easiest factor to adjust regarding successful AV deployment. Automated Vehicles and Infrastructure Enablers: Pavement Markings and Signsexamines the issues associated with pavement markings and signs in the context of advanced automation. The report focuses on unresolved issues between the AV industry and infrastructure owners and operators and provides opportunities and recommendations for the AV industry and the larger transportation community to address reliability issues.
