Abstract

A literature review that covers a wide range of sources that summarize emissions benefits and the cost-effectiveness of transportation control measures (TCMs) identified within the 1990 Clean Air Act Amendments and funded under the U.S. DOT’s Congestion Mitigation and Air Quality Improvement (CMAQ) Program. The review focused on identifying projects that have already been proposed or implemented.

Abstract

The 1990 Clean Air Act Amendments (CAAAs) and ISTEA (1991) require the use of Transportation Control Measures (TCMs) for the purpose of conforming to State Implementation Plans (SIPs) and achieving the National Ambient Air Quality Standards (NAAQS). This document provides an overview of some real-life experiences with TCM implementation and the potential of TCMs to reduce the emissions from mobile sources. The emission reduction potential of TCMs is divided into strong, weak, and speculative scenarios for the purposes of this study. The report analyzes TCMs only in context of their effectiveness and cost-effectiveness with regard to reduction of emissions and is intended to provide valuable information on the clean air effects of a variety of transportation measures.

Abstract

This report discusses several technical issues relating to spatial and temporal data aggregation and collection and its use in emission estimation. Topics such as whether vehicle emissions should be calculated on a link, corridor, or other basis and whether emissions should be estimated on an hourly, peak period, or daily basis, are discussed. The effects resulting from the use of one method versus another are outlined. Other factors contributing to these issues are also examined.
