Book excerpt: This effort addresses the need for a logic-driven process that the Virginia Department of Transportation can use to allocate resources to run-off-road and fixed-object hazards on diverse secondary road systems. In Virginia, there are approximately 60,000 miles of roadway where guardrail upgrade, installation, or related warning signs or protection may be appropriate to address run-off-road and fixed-object hazards. In this project, an information system was developed to aid the planner in guardrail resource allocation by accounting for the potential crash severities, traffic exposures, costs of treatment, and other factors. A user manual accompanying the report describes the three developed software packages (database, screening, and site evaluation) in detail, including a demonstration of the software in a case study of New Kent County, Virginia.

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.

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.

Download or read book The Safety and Cost-effectiveness of Bridge-approach Guardrail for County State-aid (CSAH) Bridges in Minnesota written by Timothy J. Gates and published by . This book was released on 2005 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridge-approach guardrail provides protection for vehicles from collision with bridge components, such as the blunt end of the bridge rail or abutment, and other types of run-off-the-road collisions. The primary objective of this research was to determine the average daily traffic (ADT) at which the benefit/cost ratio for the installation of approach guardrail at county-state-aid (CSAH) bridges in Minnesota becomes greater than 1.0. A survey of state transportation agencies found that 26 of 35 responding agencies have policies or guidelines requiring placement of approach guardrail on any bridge if the bridge was built using state funds. Results of the research analyses showed that bridge-approach guardrail was effective at reducing the severity of run-off-the-road crashes occurring on the approach or departure to CSAH bridges. Fatalities and A-injury crashes accounted for only 6 percent of the crashes occurring at bridges with approach guardrail compared to 28.5 percent at bridges without approach guardrail. The subsequent benefit/cost analysis showed that bridge-approach guardrail is cost-effective (i.e., B/C> 1) for CSAH bridges with ADT greater than or equal to 300 vehicles per day (vpd). Overall, approach guardrail has a benefit/cost ratio of approximately 3.5 to 5.5. The researchers recommended that the ADT threshold for approach guardrail on CSAH bridges be set at 400 vpd, which is consistent with previous Mn/DOT standards and AASHTO low-volume local road guidelines. Approach guardrail should be considered on a case-by-case basis for bridges with ADT between 150 and 400 vpd, especially those between 300 and 400 vpd. Placement of approach guardrail at bridges with ADT less than 150 vpd is not cost-effective in most cases.
