This report presents potential improvements to the analytical framework for assessing the air quality and other benefits and costs of transportation air quality control strategies. Short- and long-range improvements are included that will enhance the metropolitan planning models being used and considered in major metropolitan areas. The report also discusses how a monitoring program can augment quantitative analysis to provide a fuller understanding of the air quality impacts of transportation control measures. A CD-ROM containing more detailed research results is included with the report.
