Assesses the impact of removing many high-emission older vehicles (1971 and earlier) from U.S. roads by encouraging owners to voluntarily scrap their cars in exchange for cash payment as a feasible strategy for reducing urban air pollution, improving overall fuel economy and stimulating the sale of new cars.

This report assesses an array of transportation policies designed to reduce energy use and describes the intersection of these policies with general transportation problems such as congestion and air pollution. The report: describes the U.S. transportation system and its energy use; presents and evaluates forecasts of energy use to 2010; compares and contrasts U.S. and European travel and energy use patterns; discusses reasons governments may choose to intervene in transportation markets; and describes and evaluates a range of policy options to reduce U.S. transport energy use, from gasoline taxes to urban planning. Its objective is to provide a balanced, qualitative perspective of issues and problems rather than a highly quantified analysis.
