Crash Cushion for Narrow Objects

摘要

A crash cushion was developed and crash tested to shield the ends of the concrete safety shape barrier (CSSB) and other narrow rigid objects. Factors considered in its development were safety, performance, cost, ease of installation and maintenance, and the use of readily available components. Four full-scale vehicular crash tests were conducted to evaluate the impact behavior of the design in accordance with recommended procedures in NCHRP 230. The crash cushion satisfactorily met the performance standards of NCHRP 230.
