A CRITICAL REVIEW OF MATHEMATICAL DIFFUSION MODELING TECHNIQUES FOR AIR QUALITY WITH RELATION TO MOTOR VEHICLE TRANSPORTATION

The objective of this study is to conduct a search of the literature to identify state-of-the-art air quality predictive schemes applicable to motor vehicle transportation. These models are necessary for environmental impact statement preparation with regard to highway design and location. Based on the models analyzed, it appears that in most circumstances, on-site parameterization of meteorological, topographical, climatological, and other features is required prior to model application. It is recommended that the simplist model that is applicable be used-a Gaussian plume model in most cases would be adequate. More complicated models should be used if the need is shown and provided more complete meteorological and air quality measurements are available for input and verification. Serious consideration should be given to selecting or obtaining a staff person or outside consulting assistance to handle cases where the applicability of a simple model might be in question. Implementation of these and other recommendations would provide the tools and resources for assessing the potential impact on air quality from proposed highway developments, and provide opportunities for minimizing undesirable environmental effects through better location and design.
