The Regional Impacts of Near-Term Transportation Alternatives

This study has attempted (1) to predict the range of pollutant emissions, and resulting air quality through 1990 in Southern California, as determined by various levels of technological emission control; (2) to predict the reduction in vehicle miles traveled (VMT) induced by various near-term incentives and disincentives; and (3) to set forth a menu of local government strategies, showing for each the consequent effect on air quality, fuel consumption, and personal mobility, along with the costs of implementing the given strategy in 1977. It is concluded that there are several combinations of transportation management alternatives that, with some change in travel habits and additional costs, can improve air quality greatly, retain mobility for the citizen, and reduce VMT by at least 20 percent. That national standards for air quality can be completely attained — even by 1990 — in Southern California remains a matter of doubt.
