TRAFFIC FLOW AND AIR QUALITY

Examples are presented and suggestions are made for the resolution of situations in which the goals of traffic flow and air pollution control are in opposition. The first example involves an isolated intersection; volumes are illustrated, the service volume for each approach is given and the techniques for calculating emissions and concentrations from traffic parameters are outlines. The effect of traffic signal settings on motor vehicle emissions is also considered. Emissions are calculated using the outputs of the Webster model on vehicle stops and starts and vehicle delay combined with appropriate emissions factors. It is suggested that it would be cost-effective if computer controlled network signalization systems currently coming on-line were designed to include air pollution considerations. Questions (listed) concerning traffic and air pollution are best answered by a dialogue among those active in the two fields.
