Scope and Objectives

There is a need for an objective, practical method of simulating the current and future impact of motor vehicles on air pollution in urban communities. Such a technique could be used to assess current concentration patterns of primary vehicular pollutants in cities, and to predict the effects of exhaust emission controls and expressway routings on future concentration patterns. This report describes our progress in developing a simulation model designed to meet these objectives. Further refinements of this model are indicated and will be made in the course of our continuing study. In this sense, the model is not yet a completely finished product, and any present applications should be carried out with caution.

In developing the model, we have been aided considerably by previous urban diffusion modeling studies, which have been reviewed and summarized by Wanta (1968), *Stern (1969), Moses (1969), and Neiburger (1968). An investigation of carbon monoxide diffusion in Washington, D.C, by Ott et al. (1967) and Clarke's (1964) model could be considered prototypes for the model described here.
