The objective of this project was to develop an inventory of quantitative asset-level, project-level, or corridor-level processes and models for predicting life-cycle costs associated with the preservation and replacement of highway assets. The report includes a literature review, a survey of highway agencies, and case studies that document specific highway agency experiences with LCCA.", url = "https://nap.nationalacademies.org/catalog/23515/life-cycle-cost-analysis-for-management-of-highway-assets", year = 2016, publisher = "The National Academies Press", address = "Washington, DC" } @BOOK{NAP author = "Transportation Research Board and National Academies of Sciences, Engineering, and Medicine", editor = "William Bowlby and Rennie Williamson and Darlene Reiter and Clay Patton and Geoffrey Pratt and Ken Kaliski and Karl Washburn and Judy Rochat and Ahmed El-Aassar and Harvey Knauer and Gonzalo Sanchez and Doug Barrett", title = "Field Evaluation of Reflected Noise from a Single Noise Barrier—Phase 1", abstract = "TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 218: Field Evaluation of Reflected Noise from a Single Noise Barrier\u2014Phase 1 studies the change in sound levels and characteristics caused by sound reflections off a reflective, non-absorptive noise barrier on the opposite side of a highway.", url = "https://nap.nationalacademies.org/catalog/23457/field-evaluation-of-reflected-noise-from-a-single-noise-barrier-phase-1", year = 2016, publisher = "The National Academies Press", address = "Washington, DC" }
