Abstract
Recent federal legislation and policies encourage and, in some instances, require greater consideration of the air pollution problem in the development and implementation of planning programs. These requirements encompass all scales of planning, from project planning for highways and airports to the formulation of goals, policies, and plans for entire metropolitan areas. Some research has been undertaken that will assist planners in incorporating air pollution considerations in the planning process. Thus far, the preponderance of this research has dealt with the physical aspects of the pollution problem, i.e., the generation and dispersion of air pollutants. The interrelationships between air quality and the intensity and spatial distribution of human activity need to be identified more precisely. Feasible means of positively influencing air quality through planning actions need to be determined.
