"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"--Provided by publisher.

"This is a report on a research agenda to better inform future societal decisions on ocean CDR [carbon dioxide removal]; the Committee is not advocating either for or against possible future ocean CDR deployments, and the Committee recognizes that ocean CDR would, at best, complement the role of climate mitigation approaches including decarbonization"--Page viii.

Current methodologies for the in-service performance evaluation (ISPE) of roadside safety features are not viable and practical for all state departments of transportation. The research team developed an ISPE process that is sensitive to the data and resource constraints of Texas Department of Transportation (TxDOT). The following methodology was used to develop The TxDOT-ISPE process: identify the objectives of the ISPE, estimate expected extent of data collection, evaluate existing DOT procedures and organizational structure, identify features to be included in the ISPE, develop framework for an ideal ISPE, identify system constraints within the DOT, identify alternative methodologies and data sources for the ISPE, design DOT-specific ISPE process, design and conduct a pilot test of the ISPE, evaluate the data collection methodology and data quality during the pilot test, and recommend an ISPE process for TxDOT.
