Book excerpt: This report summarizes research on traffic barrier performance conducted by New York from 1983 through 1987, which concentrated on 1) development of height standards and tolerances for light-post barriers, 2) barrier performance related to vehicle characteristics, 3) development of an economic model to compare median barrier costs, and 4) effects of curbs on barrier performance. Accident data were obtained for approximately 3300 accidents occurring between July 1, 1982 and June 30, 1983. Of these, about 1700 were at light-post barrier sites.

This book was released on 1980 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic barriers are roadside hardware of various designs and materials which are intended to protect vehicles from such off-the-road hazards as trees, embankments, ravines, signposts, bridge support pillars or abutments, or other hazards. The National Transportation Safety Board (NTSB) has been concerned with the problem of inadequate traffic barriers for several years. The Safety Board has investigated accidents in which barriers failed, and has made recommendations to the FHWA. Of primary importance among these have been recommendations that the FHWA develop and promulgate mandatory performance standards for traffic barriers. The purpose of such standards would be to require that traffic barrier types be crash-tested to demonstrate their ability to meet a set of established safety criteria. At present, barriers are not required to meet such criteria through crash-testing. The purpose of this report is to review past Safety Board concerns regarding the adequacy of bridge and highway rail systems and to evaluate the FHWA's efforts to develop safer traffic barriers. This study analyzes the results of recent crash-testing sponsored by the FHWA and makes recommendations concerning performance standards for traffic barriers.

Download or read book Vehicle Compatibility in Automotive Crashes written by Stanley H Backaitis and published by SAE International. This book was released on 2005-03-29 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: For years, reducing the number of traffic-related fatalities and injuries has been a major problem throughout the world. Today, it has gained much more momentum in view of rapidly increasing SUV, van, and light-truck populations relative to the number of passenger cars, and due to significant improvements in technologies that facilitate a better understanding of the interaction dynamics among widely differing size vehicles. Unless disparities in crashworthiness among vehicles of different masses, sizes, and structural characteristics in mixed crash environments are successfully taken into account, the challenge toward improved vehicle safety will continue. This two-part compendium provides the most comprehensive information available on the entire spectrum of vehicle crash compatibility. The first part presents oral comments captured from the 2003 SAE World Congress panel discussion on compatibility. The panel of leading experts representing industry, academia, and government provides a rough framework and a broad range of views on current and emerging developments in compatibility research. The second part of this compendium features 44 best technical papers from SAE International and the International Technical Conference on the Enhanced Safety of Vehicles, published from the early 1970s through 2004. Readers will get a feel for the direction passenger car and heavy-vehicle manufacturers, research institutions, infrastructure suppliers, insurers, and governments are taking to reduce the number of traffic fatalities and injuries.
Download or read book Evaluation of the Performance of Portable Precast Concrete Traffic Barriers written by Frank N. Lisle and published by . This book was released on 1978 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The portable precast concrete traffic barrier is used to separate high speed vehicular traffic and construction activities. However, since there was a lack of information on the barrier's performance in a construction zone environment, officials of the Virginia Department of Highways and Transportation requested that the Virginia Highway and Transportation Research Council evaluate the performance of the barrier during the widening of the Virginia Beach-Norfolk Expressway (Rte. 44). The scope of the evaluation included (1) a review of the literature on the performance of the concrete "safety shape" barriers, (2) an examination of the accident data before and during construction on Rte. 44 to determine the effects of construction on the frequency and characteristics of traffic accidents, (3) an analysis of tire marks and barrier-involved accidents to determine the effectiveness of the barriers in safely redirecting vehicles, and (4) an examination of the effects of construction on traffic characteristics. The literature review revealed that in using the precast concrete traffic barrier the following factors should be considered: (1) the end of the barrier should never be exposed to oncoming traffic; (2) the barrier joints must be tight for the barriers to act as a system; (3) the longitudinal axis of the barriers should be placed parallel to the roadway, except when the barrier system is started with a flare; (4) the barrier system should have a minimum length of 100 feet (30 m); and (5) the barrier system must have lateral support in order to prevent vehicle penetration. For conditions on Rte. 44, it was found that (1) there was an average of 49 vehicle contacts with the barrier for every reported accident in which the barrier was involved; (2) there was a definite tendency for motorists to stay out of the barrier lane, but avoidance of the barrier lane was reduced as volume increased; and (3) with a 55 mph (88 km/h) posted speed limit, the vehicular speeds were reduced by only a few miles per hour when the barriers were in place. Evaluation of the barrier's performance during the widening of I-95 is recommended, since that highway carries a much higher volume of tractor-trailers than does Rte. 44.
