CMAQ Emissions Calculator Toolkit: On-Road Activity Calculator
The purpose of the Congestion Mitigation and Air Quality Improvement Program Emissions Calculator Toolkit (CMAQ Toolkit) is to help a user with limited modeling experience estimate emission reductions associated with implementation of a CMAQ-funded project. The CMAQ Toolkit uses emission rates and activity data based on national-scale runs of the U.S. Environmental Protection Agency’s (EPA) Motor Vehicle Emission Simulator (MOVES). The on-road activity calculator is a tool that was designed to help calculate specific activity values for the diesel retrofit and repower/replacement tools based on aggregate activity data. This document is organized into three sections – User Guide, Tool Methodology, and Examples – to aid the user in understanding and using this calculator in conjunction with the emission reductions calculators. The User Guide gives direction for the user to properly input values into the tool and provides definitions of both user inputs and tool outputs. The Tool Methodology outlines the equations and assumptions used to calculate activity values. The Examples included herein are also included in the documentation for the retrofit or repower/replacement tool, to aid in use with the project tools in calculating emission reductions.
