- Impacts on state and local agencies for maintaining traffic signs within minimum retroreflectivity guidelines / by McGee, Hugh W.(CARDINAL)311202; Taori, Sunil.(CARDINAL)314382; United States.Federal Highway Administration.Office of Safety and Traffic Operations Research and Development.(CARDINAL)172825; Bellomo-McGee, Inc.(CARDINAL)311201; Turner-Fairbank Highway Research Center.(CARDINAL)286897;
Includes bibliographical references (page 44).Introduction -- Guidelines for minimum levels of inservice retroreflectivity -- Data provided by state and local agencies -- Sign replacement estimates -- Responses from agencies -- Nationwide estimate of sign replacement costs -- Discussion -- Appendices -- References.Task A report;The Federal Highway Administration (FHWA) has developed guidelines for minimum retroreflectivity levels for four groups of signs: 1) yellow/orange-on-black warning signs, 2) black-on-white regulatory signs, 3) white-on-red regulatory signs, and 4) white-on-green guide signs. This report presents data on percentage of signs by the various types of retroreflective sheeting for both States and local agencies, a distribution of age of signs by type of sheeting, and the percentage of signs that would not meet the minimum retroreflectivity values. The report also presents a summary of the data and comments provided by the participating agencies related to the minimum retroreflectivity values.Performed by Bellomo-McGee, Inc. (BMI) and sponsored by the Federal Highway Administration Office of Safety and Traffic Operations R & D under contract no.
