PROVIDING FOR AIR QUALITY AND URBAN MOBILITY

The process of incorporating air quality considerations in planning, the basic relations between transportation and air pollution, techniques for achieving air quality, and the institutional difficulties of implementing transportation control techniques are discussed in this exploration of ways in which air pollution considerations might be incorporated in the decision-making process. The air quality problem related to transportation is not solely a function of vehicle emissions, and the planner must understand how factors such as direction and speed of wind, time of day, and physical barriers affect the problem. Primary and secondary air quality standards established by federal and state governments are discussed and tabulated. The relation of vehicle technology and the effects of speed, travel mode, and operation mode on the emission of pollutants are set forth. Techniques of air quality control are grouped into programs oriented toward vehicles, traffic flow, and reduction of pollution concentration. There is a need for improvement of communications between DOT and EPA, and obstacles that may arise are noted. The report shows that transportation control techniques may be used to achieve air quality (some of these may infringe on mobility goals and others may not). It is suggested that short-term actions aimed at ameliorating air pollution must aim at fostering communication among responsible agencies. Long-term actions require research and more analytical information. /Author/
