Description
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)

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.

Data Needs for Tree Removal Crash Modification Factors on Arizona State Highways

The Arizona Department of Transportation (ADOT) Roadway Departure Safety Implementation Plan (RDSIP) has identified tree removal as a feasible countermeasure to reduce roadway departure crash frequency or severity. Previous ADOT work has identified locations for tree removal, and activities to conduct this work are underway. To test the safety effectiveness of removing the trees, ADOT intends to conduct statistically rigorous before-after safety effectiveness analysis to estimate state-specific crash modification factors (CMFs).
