Government Accountability Office and published by Createspace Independent Publishing Platform. This book was released on 2017-07-25 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: " In 2014, 54 percent of traffic fatalities in the United States occurred as a result of a vehicle's leaving the roadway, according to U.S. Department of Transportation's (DOT) data. Roadside safety hardware, such as guardrails, is meant to reduce the risk of a serious crash when leaving the roadway. But in the last several years, a number of serious injuries and deaths resulted from crashes into roadside safety hardware. GAO was asked to review FHWA's oversight framework for roadside safety hardware. This report assesses: (1) how FHWA performs oversight of state policies and practices related to roadside safety hardware; (2) the laboratory crash-testing process and FHWA's oversight of this process; and (3) the extent to which information is available on roadside safety hardware's performance once installed. GAO reviewed federal and state policies, surveyed state DOTs and received 44 responses, and reviewed documentation from nine U.S. crash test labs. "

Book excerpt: Traffic crashes kill thousands of Americans every year -- in 2005, it was the the leading cause of death among young Americans. To try to improve highway safety, Congress authorized a grant program overseen by the Nat. Hwy. Traffic Safety Admin. (NHTSA). In 2003, it was recommended that NHTSA improve the consistency of its mgmt. reviews, a key aspect of NHTSA¿s oversight. In response to a legislative mandate, this report assessed: (1) how states have used grant funding to address safety goals; (2) NHTSA¿s progress in improving consistency in its mgmt. reviews; (3) the usefulness of its mgmt. review recommendations; and (4) approaches to further improve safety. Includes recommendations. Charts and tables.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Government Accountability Office (GAO) is an independent agency that works for Congress. The GAO watches over Congress, and investigates how the federal government spends taxpayers dollars. The Comptroller General of the United States is the leader of the GAO, and is appointed to a 15-year term by the U.S. President. The GAO wants to support Congress, while at the same time doing right by the citizens of the United States. They audit, investigate, perform analyses, issue legal decisions and report anything that the government is doing. This is one of their reports.

Book excerpt: Fatalities on U.S. roads now total over 40,000 each year. Future reductions may require the Dept. of Transportation (DoT) to address new trends such as evolving crash-avoidance technologies and rapidly changing electronic devices that may distract drivers who use them on the road. This report examines how DoT is addressing fast-moving trends such as these, and examines how DoT is: (1) deciding on responses to the crash avoidance and electronic distractions trends --given available evidence and uncertainties; (2) developing new evidence on these trends' safety impacts; and (3) communicating with the Congress about these and other trends and related issues. Includes recommendations. Illustrations.

Download or read book Risk Management and Assessment of Upgrading and Standardizing Guardrail written by Karen Zhu and published by Purdue University Press. This book was released on 2009-03-01 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Indiana Department of Transportation (INDOT) has installed guardrail systems on interstate highways and other highways in accordance with a variety of standards throughout the years. Traffic volume has increased and the posted speeds have been raised on most INDOT's interstate highways. Consequently, the characteristics of run-off-the-road (ROR) crashes may have changed. In the meantime, material prices have increased considerably and the guardrail maintenance and crash repair costs have increased accordingly. There is no doubt all these changes will not only greatly affect the ROR crash prediction, but also greatly affect the guardrail benefit/cost analysis. This study examined the current use of roadside guardrails on INDOT intestates, State highways, and US highways, roadways, including types and lengths of guardrails, types and numbers of guardrail end treatments, and field guardrail positions. Based on the records of total 4657 ROR crashes occurred in 2004 and 2006, this study investigated the characteristics of ROR crashes, such as frequencies and locations of ROR crashes, crash consequences (number of vehicles involved, injuries and fatalities), and the effects of main factors, in particular roadway geometrics, seasons and traffic volume, on the highways of different classes. Furthermore, this study investigated the features of vehicle-guardrail crashes, including impact positions and corresponding frequencies and consequences. ROR crash predictions were examined in all aspects in this study, including encroachment rates, crash probabilities, and severity probabilities. It was found that the encroachment rates obtained by this study are less than those in the AASHTO Roadside Design Guide. This study evaluated the issues associated with the guardrail crash repair costs, such as parts costs, labor costs, and equipment costs.

Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state department of transportation (DOT) roadway design, traffic, structural, maintenance, and research engineers and others concerned with highway safety issues. This synthesis describes the current state of the practice for the use of guardrails and median barriers and their crashworthiness. It includes information about the crashworthiness and typical applications of the most common, permanently installed, nonproprietary guardrail and median barrier systems used in the United States today. A significant amount of detail is included in the text to aid the design, selection, and locating processes for safe and effective guardrails and median barriers. The report presents data obtained from a review of the literature and a survey of state DOTs. The synthesis presents a description of the typical longitudinal barriers in use today, including drawings, the extent of their use, and the most recent testing on each guardrail and barrier system, with particular emphasis on NCHRP Report 230 and 350 requirements. In addition, it discusses the maintenance issues, cost constraints, and common problems with each type of barrier. The synthesis only discusses the crashworthiness of guardrails and median barriers; their transitions and terminals are not discussed.
