Abstract:This report presents the development of a comprehensive air quality planning tool designed to enhance the capabilities of transportation agencies in evaluating and mitigating vehicular emissions. Transportation activities are a source of air pollution and greenhouse gas emissions, impacting public health and contributing to climate change. Despite various strategies implemented by federal and state transportation agencies through programs like the Congestion Mitigation and Air Quality Improvement (CMAQ) Program, current tools for assessing the environmental benefits of transportation projects often lack comprehensive coverage, user-friendliness, and up-to-date data, limiting their effectiveness. To address these shortcomings, this project proposes the creation of an Excel-based air quality assessment tool that integrates the latest advancements in emission modeling, including updates to the MOVES (Motor Vehicle Emission Simulator) model. The tool aims to be accessible to non-specialists, enabling state and local transportation agencies to conduct precise and consistent evaluations of proposed projects. It covers a wide range of project types and incorporates user-friendly features to standardize the assessment process, ensuring that CMAQ-funded initiatives achieve maximum air quality benefits. The report details key areas of development, including the preparation of vehicle emission rates using the MOVES model, functionality of specific calculators tailored to projects such as Electronic Open-Road Tolling (EORT), telework programs, transit bus upgrades, and fleet expansions. Additionally, the report provides practical application guidelines and user instructions to ensure effective use of the tool. By accommodating all eligible transportation project types and integrating the latest emission modeling advancements, the tool provides a robust framework for air quality management, supporting better regulatory compliance, environmental protection, and sustainable development goals. Ultimately, this project aims to improve air quality assessments, ensure more effective allocation of CMAQ funds, and enhance environmental quality across various regions, contributing to a cleaner and healthier environment aligned with broader policy objectives.
