In-Service Performance of Energy-absorbing W-beam Guardrail End Treatments: Phase 1


Project Scope:

An ad hoc committee will develop an appropriate research design for evaluating the in-service crash performance of the more common energy-absorbing W-beam guardrail end treatments currently installed throughout the United States. The study will also determine the data required to carry out the analysis and include exploratory work in selected states to determine whether the required data, either retrospective or prospective, would be available in sufficient quantity and quality to allow meaningful inferences to be drawn about in-service performance of end treatments collectively and individually.  Based on the results from the exploratory work, the committee will identify appropriate next steps for either gathering data or, should it appear unlikely that the necessary data would become available, advise states on the existing process of conducting in-service evaluations of guardrail end treatments
