A popular application of this method is the evaluation of the effectiveness of emissions reduction\u003Cbr \/\u003E\r\ntreatments (e.g. vehicle Inspection and Maintenance (I\/M) programs) by comparing the emissions from the\u003Cbr \/\u003E\r\ntreated (experimental) fleet to those of an untreated (reference) fleet. Since no two large vehicle fleets are\u003Cbr \/\u003E\r\nidentical, the reference fleet is produced synthetically by application of correction factors. Current federal\u003Cbr \/\u003E\r\nguidance assumes that closely located experimental and reference fleets behave similarly if normalized by\u003Cbr \/\u003E\r\nmodel year distribution and Vehicle Miles Traveled (VMT). However inconsistency in the results from these\u003Cbr \/\u003E\r\nevaluations questions whether these controls are sufficient to estimate emission reductions attributed to\u003Cbr \/\u003E\r\nI\/M with an acceptable level of uncertainty.\u003Cbr \/\u003E\r\nIn addition to age and mileage accumulation, emissions from vehicle fleets can be influenced by\u003Cbr \/\u003E\r\ndifferences in a variety of other factors including differences in fuels and usage patterns and\u003Cbr \/\u003E\r\nsocioeconomic factors that can influence fleet composition and maintenance trends. This study evaluates\u003Cbr \/\u003E\r\nthe influence of variety of these factors in determining the reference fleet correction factors for the Macon\u003Cbr \/\u003E\r\nand Augusta Georgia fleets for evaluation of the Atlanta, GA I\/M program over a twelve-year period from\u003Cbr \/\u003E\r\n1998 to 2010. A series of \u0026quot;null\u0026quot; experiments were conducted to evaluate factors that might affect\u003Cbr \/\u003E\r\nemissions across vehicle fleets of the same model year distribution. These results showed in addition to\u003Cbr \/\u003E\r\nmodel year and VMT, the reference fleet also required normalization by vehicle type and, in certain cases,\u003Cbr \/\u003E\r\nfuel composition to produce a reliable reference fleet correction factors.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Developing Correction Factors for Reference Fleet.
