An Implementation Guide for Minimum Retroreflectivity Requirements for Traffic Signs
Author: Hugh W. McGee
Publisher:
ISBN:
Category : Reflectance
Languages : en
Pages : 64
Book Description
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.

Impacts on State and Local Agencies for Maintaining Traffic Signs Within Minimum Retroreflectivity Guidelines

ISBN:
Category : Reflectance
Languages : en
Pages : 54
Book Description
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. The 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.
