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 Synopsis Impacts on State and Local Agencies for Maintaining Traffic Signs Within Minimum Retroreflectivity Guidelines by : Hugh W. McGee
Download or read book Impacts on State and Local Agencies for Maintaining Traffic Signs Within Minimum Retroreflectivity Guidelines written by Hugh W. McGee and published by . This book was released on 1998 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1995 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Transportation Asset Management by : Zongzhi Li
Download or read book Transportation Asset Management written by Zongzhi Li and published by CRC Press. This book was released on 2018-08-31 with total page 761 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transportation asset management delivers efficient and cost-effective investment decisions to support transportation infrastructure and system usage performance measured in economic, social, health, and environmental terms. It can be applied at national, state, and local levels. This distinctive book addresses asset management for multimodal transportation, taking account of system component interdependency, integration, and risk and uncertainty. It sets out rigorous quantitative and qualitative methods for addressing system goals, performance measures, and needs; data collection and management; performance modeling; project evaluation, selection, and trade-off analysis; innovative financing; and institutional issues. It applies as easily to static traffic and time-dependent or dynamic traffic which exists on a more local level. It is written for transportation planners, engineers, and academia, as well as a growing number of graduate students taking transportation asset management courses.
Book Synopsis Retroreflective Requirements for Traffic Signs - a STOP Case Study. Final Report by : Juan M. Morales
Download or read book Retroreflective Requirements for Traffic Signs - a STOP Case Study. Final Report written by Juan M. Morales and published by . This book was released on 1987 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study determined the performance of STOP signs based on their retroreflective properties. Thirty-five 30-inch STOP signs, including engineering grade and high intensity, were measured in the laboratory to determine their retroreflective properties. A subset of ten signs was taken to the field to determine how far they could be recognized by paid subjects. Mathematical relationships between the various retroreflective properties and recognition distance were developed. The overall specific intensity per unit area (SIA) was found to be a good measure for estimating the recognition distance of STOP signs.
