Download or read book Overhead Guide Sign Visibility Factors written by Anthony C. Stein and published by . This book was released on 1989 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project discussed in this report concerned the night use of overhead guide signs, including button and reflectorized copy and all practical combinations of reflectorized and opaque backgrounds. This project was a follow up effort to the literature review by Gordon. Gordon's review found areas requiring further investigation, including the comparison of nonilluminated nonretroreflectorized signs with both illuminated nonretroreflectorized and retroreflectorized signs.

Download or read book Freeway Guide Sign Replacement written by Hugh W. McGee and published by Transportation Research Board. This book was released on 1991 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to traffic engineers, planners, and others interested in making sure that motorists' needs for directional information on freeways are being met. Information is provided on policies and procedures used by states in evaluating freeway guide signs and replacing those that are outdated or deteriorated. Many signs on freeways and other controlled-access highways have exceeded their service life and are no longer serving motorists' needs. This report of the Transportation Research Board describes the policies, proceduress, and criteria used by states for freeway sign evaluation and replacement programs.
Download or read book Characteristics and Needs for Overhead Guide Sign Illumination from Vehicular Headlamps written by Eugene Russell and published by . This book was released on 1999 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: A team of Kansas State University researchers was given a contract to determine the minimum luminance requirements for overhead guide signs and to determine if the illuminance from vehicle headlamps on highways was sufficient to provide drivers with this required minimum luminance. This report covers a literature review to determine the minimum luminance value needed, an overview of the equipment developed for field studies of vehicle headlamp illuminance, results of a small laboratory study to determine minimum luminance of highway guide signs, and the results of field studies to determine illuminance values from a sample of the fleet of vehicles on highways, and the results of a study of illuminance values obtained from the headlamps of 50 known vehicles of varying ages and types.
