An Implementation Guide for Minimum Retroreflectivity Requirements for Traffic Signs
Author: Hugh W. McGeePublisher:
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.

Pages : 80
Book Description
The objective of this report is to give a preliminary assessment of the impact that revised retroreflectivity requirements will have on the State of Montana. Conclusions and recommendations are made future management and handling of sign inventory data in Montana. This objective is addressed through the following tasks: Task A: Review, assimilation and analyses of current literature available on a nationwide basis; Task B: Discussion of results from a multi state phone solicitation regarding state sign management practices and policies; Task C: An assessment of sign reflectivity inspection equipment and sampling methodology; and Task D: Evaluation of Montana sign inventory on the basis of current practices and condition of a limited sampling of signs. Recommendations of this report include upgrading of, or improvements to Montana Department of Transportation sign management system and multi-district statewide retroreflective sampling to better determine the impacts revised standards may have.

Book Description
The Manual on Uniform Traffic Control Devices (MUTCD) now specifies minimum retroreflectivity requirements. These requirements include an obligation for agencies to develop a strategy for maintaining compliance. With budget considerations, it is important that transportation agencies be able to efficiently assess the performance of their assets and adopt management strategies to comply with such requirements. As a foundational work, this research develops specific methodology for assessing the condition and performance of sign assets that are maintained by a large transportation agency. In doing so, this research provides for the determination of key elements that should be considered when developing any sign asset management strategy. This work incorporates and builds upon previous research in order to develop an assessment strategy that can provide new insight and understanding into where sign asset management efforts should be focused. Given the conditions unique to the Utah Department of Transportation's (UDOT) sign assets, the findings of this research present a potential paradigm shift from the previous assumptions regarding the best prospective management practices. Sign damage was determined to be the primary issue affecting the nighttime visibility of UDOT maintained signs. By controlling damage issues within UDOT's sign assets, retroreflectivity compliance may be maintained. The findings of this research provide for new options and considerations in managing both sign retroreflectivity and nighttime visibility at a large scale.
