摘要：	TRB Special Report 323: In-Service Performance Evaluation of Guardrail End Treatments develops a research design for evaluating the in-service performance of guardrail end treatments and other roadside safety devices and identifies the data required to do so. Given the substantial data requirements and methodological challenges of conducting successful evaluations of particular end treatments, the committee concludes that state highway agencies will require more information about the benefits, costs, and practicality of routine in-service evaluation of end treatments in general before deciding to undertake new data collection and analysis programs necessary to carry out more challenging analyses. The committee recommends research to advance practice and test the feasibility of and costs associated with more complex evaluations. It also recommends research to examine whether procedures for testing the performance of devices should be altered. Associated with the report, three working papers are available online: Chad Heimbecker and Eric Lohrey: Examples of State Highway Agency Practices Regarding Design, Installation, Maintenance, and Evaluation of Guardrail End Treatments Bhagwant Persaud: Critical Review of Methodologies for Evaluating In-Use Safety Performance of Guardrail End Treatments and Other Roadside Treatments Brian Wolshon and Anurag Pande: Critical Review of Methodologies for Evaluating In-Use Safety Performance of Guardrail End Treatments and Other Roadside Treatments The report is accompanied by a two-page highlights document summarizing the findings and recommendations.
