This report provides an implementation plan that allows the Arizona Department of Transportation and other agencies in Arizona to make optimal use, through local data inputs, of the United States (US) Environmental Protection Agency's (EPA) Motor Vehicle Emissions Simulator (MOVES) model. MOVES is the federally approved mobile source emissions model for use in State Implementation Plan development and conformity analysis, and is recommended for other transportation air quality analysis purposes. EPA requires or recommends using local data for many of the model's inputs. This report includes an assessment of Arizona-specific data and the processing necessary to create these inputs, plus a demonstration of data-processing procedures using Yuma County as a case study. The recommendations are intended for applying the MOVES model anywhere in the state of Arizona, but are not meant to supersede work by metropolitan agencies that may use more detailed data than available in other regions of the state. This study focuses on the latest release of the model, MOVES2014.
