Overview of Literature Review Sample Clauses

Overview of Literature Review. The research team conducted a literature review of peer reviewed publications and grey literature, which focused on a broad scope of material including project level and hot-spot analysis for carbon monoxide (CO) and particulate matter (PM), and project level analysis for air toxics. Not reviewed here are EPA guidance documents. The review focuses principally on relatively recent studies—published within the past ten years, but also includes several older publications that warranted review because of their particular relevance and historical perspective. Several hundred studies were initially identified, roughly a fourth of which merited a review of the abstract. Of these, twelve journal articles or technical reports were selected for detailed review. The key findings of these twelve studies are summarized below. The material is organized into two subsets: The first set of summaries provides historical perspective for project level analyses and for the framework under which they are performed. Most of these studies are based upon use of the MOBILE emission factor model or California’s EMFAC model, but present information still relevant to this study. The second set of summaries focuses on more recent papers that are based upon use of the MOVES model. The review places greater emphasis on the more recent studies.
