Book Description
The objective of the research project was to collect crash test data relating to bridge rails and median barriers, to collect information about common attachments to traffic barriers, and to evaluate this information for the purpose of developing guidelines for the design and placement of traffic barrier attachments. A comprehensive review of full-scale crash testing of bridge rails and median barriers was conducted in order to establish Zones of Intrusion (ZOIs) for traffic barriers. The primary goal of this review was to identify the extent that a pickup or single-unit truck intrudes over the top of a traffic barrier during a vehicular impact.

Roadside Design Guide
Author: American Association of State Highway and Transportation Officials. Task Force for Roadside Safety
Publisher: AASHTO
ISBN: 1560515090
Category : Technology & Engineering
Languages : en
Pages : 345
Book Description
"The Roadside Design Guide presents a synthesis of current information and operating practices related to roadside safety and is written in dual units-metric and U.S. Customary. This book is a guide. It is not a standard, nor is it a design policy. It is intended to use as a resource document from which individual highway agencies can develop standards and policies. Although much of the material in the guide can be considered universal in its application, several recommendations are subjective in nature and may need modification to fit local conditions. However, it is important that significant deviations from the guide be based on operational experience and objective analysis. The 2011 edition of the AASHTO Roadside Design Guide has been updated to include hardware that has met the evaluation criteria contained in the National Cooperative Highway Research Program (NCHRP) Report 350: Recommended Procedures for the Safety Performance Evaluation of Highway Features and begins to detail the most current evaluation criteria contained under the Manual for Assessing Safety Hardware, 2009 (MASH). For the most part, roadside hardware tested and accepted under older guidelines that are no longer applicable has not been excluded in this edition." -- AASHTO website.

Guide for Selecting, Locating and Designing Traffic Barriers. Volume I - Guidelines. Final Report
Author: H. E. Ross (Jr)
Publisher:
ISBN:
Category :
Languages : en
Pages : 268
Book Description
The guide presents the results of a synthesis of current information on the various elements of traffic barrier systems, including warrants, structural and strength characteristics, maintenance characteristics, selection criteria, and placement data. Criteria on these elements are summarized for each of the four basic barrier types, namely, roadside barriers (heretofore commonly referred to as guardrails), median barriers, bridge rails and crash cushions. A chapter on a cost-effective selection procedure is included, primarily to provide the highway engineer with an alternate approach to the more conventional means of establishing barrier need and a barrier selection if warranted.

Self-restoring Median Barriers and Bridge Railings
Author:
Publisher:
ISBN:
Category : Bridge railings
Languages : en
Pages : 62
Book Description
The development of the self-restoring (SERB) guardrail system for the Federal Highway Administration (FHWA) demonstrated that a high performance flexible barrier that was damage resistant was technically and economically feasible. This report (Volume I) describes the design and development of the SERB bridge rail retrofit and SERB median barrier systems which have been fully evaluated. The barriers were subjected to a full range of impacts including 40,000-lb (18,000-kg) buses and 1,800-lb (800-kg) cars.
