A project is described which had the objectives of evaluating transportation controls in the reduction of motor vehicle emissions and to predict the impact of the expected emission reductions on air quality in six metropolitan areas. The companion report, 'Evaluating Transportation Controls to Reduce Motor Vehicle Emissions in Major Metropolitan Areas' (PB-213 374) provided a general analytic framework upon which these more specific analyses of the six metropolitan areas was prepared. This report details the data collection and specific analysis performed in Chicago, New York, Denver, San Francisco, Los Angeles, and Washington, D.C. The sources of transportation and other data are identified and the limitations of the data base are described. Analytic projection of emission rates and predicted concentration levels are given for each of the defined transportation control conditions. (Author)
