Book Synopsis Larger Observation Angles for Retroreflective Sheeting Material Specifications and Measurements by : Paul J. Carlson
Download or read book Larger Observation Angles for Retroreflective Sheeting Material Specifications and Measurements written by Paul J. Carlson and published by . This book was released on 2004 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current U.S. practice for measuring retro-reflective sheeting materials for traffic signs primarily is based on a standard measurement geometry of 0.2 degrees and -4.0 degrees, referring to the observation and entrance angles of retro-reflectors, respectively (correct?). When combined, these two angles represent a specific geometry for testing retro-reflective sheeting materials. This geometry was chosen for various reasons, but it does not reflect realistic driving situations. This report details the work that was performed to reevaluate the specified geometry for measuring the performance of retro-reflective sheeting materials. The recommendations include a revised standard measurement geometry for retro-reflective sheeting materials, various changes to the appropriate specifications, a revised set of minimum in-service retroreflectivity levels at the revised standard measurement geometry, and considerations for how agencies can accommodate larger vehicles with respect to the proposed minimum retroreflectivity levels.

Book Synopsis An Implementation Guide for Minimum Retroreflectivity Requirements for Traffic Signs by : Hugh W. McGee
Download or read book An Implementation Guide for Minimum Retroreflectivity Requirements for Traffic Signs written by Hugh W. McGee and published by . This book was released on 1998 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: To assist agencies in developing a cost-effective program for timely replacement of ineffective signs, this document was prepared. Initially the report describes the principles of retroreflectivity, the types of retroreflective materials, and the proposed minimum retroreflectivity guidelines. Then, the report presents the concept of a sign management system, and provides guidance for developing a sign inventory, conducting sign inspections, and maintaining signs. The report concludes with discussing options that State and local agencies can follow for replacing their ineffective signs and offers a minimum and desirable program.

Book excerpt: Prepared by the Environmental Technology Evaluation Center (EvTEC), a CERF Service Center. This report presents the findings from a June 1997 Environmental Technology Needs Survey conducted by EvTEC. The survey was developed to help EvTEC gain a better understanding of present practices and procedures in evaluating new products and determine how EvTEC could best respond to the needs of all stakeholders in the environmental community. The survey contained general information questions as well as specialized questions for three groups: users and regulators of environmental products; entrepreneurs who invent, develop, or market new technologies and products; and research institutes and testing labs that carry out product and technology evaluations.
