| 摘要： | The U.S. Environmental Protection Agency (EPA) is responsible for developing and regularly updating the models that are used to estimate mobile source emissions for purposes of air quality planning purposes in all areas of the United States outside of California. In December 2009, EPA moved to an entirely new modeling platform referred to as the Motor Vehicle Emission Simulator (MOVES) model. MOVES allows the assessment of vehicle emissions at both macro- and micro-scale levels. The innovative methods that define MOVES relative to the predecessor model known as MOBILE also require a wholly new set of underlying databases and categorization schemes. Given this, the accuracy of MOVES depends in large part on the underlying data supporting these new methods, which underwent substantial revision during the development of MOVES2014 from MOVES2010. The project scope included three distinct elements: (1) a critical evaluation of selected modeling methodologies, data, and assumptions; (2) analyses of emissions inventories prepared using MOVES2014 for selected cities; and (3) a comparative analysis of the impact of gasoline properties on exhaust emissions from the latest-technology vehicles from studies independent of the MOVES model development. This review involved a detailed examination of the model methods, data, and assumptions, focusing on areas for further improving the model. The examination resulted in a series of recommendations, the most significant of which, in terms of the potential impact on the emission inventory, addressed the following areas: Emission rates for heavy-duty diesel vehicles; Emission rates for light-duty gasoline vehicles; Assessment of fuel properties on emissions; and Assessment of impacts of inspection and maintenance (I/M) programs on light-duty vehicle emissions. The primary findings and recommendations of the critical evaluation are summarized in the report. During the course of executing this project, the U.S. Environmental Protection Agency (EPA) released MOVES2014a in November 2015. A number of the findings from the critical evaluation of MOVES2014 were subsequently addressed by the agency in MOVES2014a, and are documented in an Appendix of the report. |
