This paper analyzes a variety of transportation control policies which include expanded use of public transportation, better traffic controls in central areas, relocation of workplaces and residences, restrictions on automobile parking and use in central business districts. An attempt is made to predict the potential impact of such policies in Boston and Los Angeles, two cities with significantly different transportation systems and land use patterns. The aim of the study is to clarify the potential role of transportation control policies in air quality improvement programs, comparing them--within a cost effectiveness framework--with programs for achieving emission rate reductions from automobiles. By using the Transportation and Air Shed Simulation Model (TASSIM) the analysis shows that the effectiveness of several of the transportation control policies is somewhat similar in the two cities. A major conclusion suggests that although transportation controls can achieve significant improvements in air quality in limited portions of an air quality region they probably cannot yield an air quality improvement as large as that resulting from the reduction in emission rates presently envisaged. /DOT/
