Accession Number: 01666989
Record Type: Component
Availability: Find a library where document is available Abstract: Highway agencies install many different types of guardrail end treatments, all intended to absorb energy in a crash and to redirect the vehicle into a safe trajectory. The Committee for the Study of In-Service Performance of W-Beam Guardrail End Treatments, Phase 1, formed by the Transportation Research Board (TRB) and cosponsored by the National Cooperative Highway Research Program, authored TRB Special Report 323 to help highway agencies supplement crash testing with evaluations of the in-service safety performance of roadside safety devices like guardrail end treatments. This article outlines the committee's recommendations to state departments of transportation and the U.S. Department of Transportation. Recommendations include: cooperating on a program to validate and refine crash test procedures; conducting a demonstration of evaluation methods suitable for routine highway agency use; developing a statistical model to measure the effects of design, installation, and maintenance practices on performance; and the organization of a nationally coordinated evaluation research program.
