Abstract

Bridge rail and guardrail design has evolved over the years in an attempt to meet the needs of the times. The standards to which guardrails and bridge rails must perform have been made more demanding by the slow but steady increase in the average operating speed of vehicles in recent years. Researchers have been and are now responding to the needs for traffic railings with improved performance characteristics, and highway authorities have quickly put to practice the results of this research.Research efforts over the last several years have led to the development of a first generation of impact attenuators for use at roadside hazards in the gore area. The life-saving benefits of such devices have been verified through research and experimental construction.This paper discusses recent research findings in the United States in the area of the development of bridge railings, guardrails, and impact attenuators.
