Bronstad , J. Michie Published Engineering NCHRP Report This report which is a synthesis of existing information on barrier technology, test methods, and human tolerance, recommends procedures for conducting passenger vehicle crash tests of roadside appurtenances longitudinal barries such as bridges rails, guardrails, median barriers, transitions and terminals; crash cushions; and breakaway or yielding supports for signs and luminaires , and provides a commentary on these procedures.
The procedures devised to subject the appurtenances to severe… Expand. Save to Library Save. Create Alert Alert. Share This Paper. Background Citations. Methods Citations.

Minisized Automobiles and Roadside Appurtenances. The effectiveness of roadside safety appurtenances under impact with minisized automobiles is investigated. The vast majority of existing roadside hardware have been qualified under guidelines which … Expand. In summary, this procedure is … Expand. View 1 excerpt. Roadside safety devices are designed to protect vehicle occupants from injuries. Because new designs cannot be tested with human occupants, the safety of new designs has traditionally been measured … Expand.
Computer simulations of roadside crash cushion impacts. This paper presents the results of finite element computer simulations of vehicular impacts with a roadside crash cushion. Guidelines for testing and evaluating the impact performance of roadside safety features are periodically updated to stay current with improvements in technology and changes in the vehicle fleet and … Expand.
