Numerous problems have arisen in the planning and implementation of transportation controls developed under the Clean Air Act. These problems include constraints imposed on the planning process by strict statutory deadlines and limited resources: uncertainties about the nature and severity of the air pollution problems facing metropolitan areas and about the effects on health and welfare of air pollution; incomplete information about the effectiveness, costs, and implementability of transportation control options; lack of explicit investigation of social and economic effects of proposed transportation control strategies; insufficient public involvement in, and understanding of, transportation control planning; and failure to adapt the transportation control planning process to the existing institutional framework. Despite these problems, transportation controls can have multiple benefits, not only improvement of air quality but also more efficient use of the existing transportation system, energy conservation, increased safety, spurred transit development and better transit services, and more rational use of scarce urban land. Thus, carefully planned transportation controls can meet multiple objectives and support community goals. Steps that can be taken by states and localities now include (a) requiring that certain decisions be made by the organization responsible for adopting a regional transportation plan; (b) coordinating the roles of all levels of government in development of transportation plans; (c) facilitating public involvement in transportation control planning; (d) requiring full impact analysis; (e) undertaking and monitoring experiments and innovations in transportation controls; and (f) requiring periodic evaluation and update of transportation control plans.
