Abstract

This report describes Intelligent Vehicle Highway System (IVHS) program contributions to air quality. It outlines the current debate on the role of IVHS in reducing congestion in light of the argument that increasing capacity will induce more travel and offset any gains made in reducing traffic congestion and emissions. The report also discusses strategies designed to reduce emissions by encouraging mode shifts and plans designed to reduce pollution, such as inspection and maintenance (I&M) programs.

Abstract

This report supports the implementation of the 1990 Clean Air Act Amendments (CAAAs) by providing information for preparing the On-Road Mobile Source section of emission inventories. It examines the current practices used by State environmental and transportation agencies, regional transportation committees, and metropolitan planning organizations in developing on-road mobile emission inventories for 33 nonattainment areas. Some innovative practices are also reviewed.

Abstract

This report examines the ozone emission trends in 20 areas classified by the U.S. Environmental Protection Agency as either serious or severe for nonattainment of the ozone standard over the years 1980-1993. Trends were evaluated to determine their statistical significance and to compare the magnitude and direction of the trends on an urban, regional, and national basis. In performing the analysis, several factors were considered, including meteorology, geographic variations, and effects
of economic growth.
