Transportation Controls to Reduce Automobile Use and Improve Air Quality in Cities: The Need, The Options, and Effects on Urban Activity.
The Clean Air Amendment of 1970 required the Administrator of the Environmental Protection Agency (EPA) to establish national primary and secondary ambient air quality standards. The primary standards are and must be established so that their attainment and maintenance will protect the public health with an adequate margin of safety. The secondary standards are to protect the public welfare from any known or anticipated adverse effects associated with the presence of air pollutants in the atmosphere. The pollutants for which ambient air quality standards have been promulgated include carbon monoxide and oxidants. The automobile is the principal source of carbon monoxide and oxidants in urban areas.
