INTRODUCTION

General Program Objectives

The long-term objective e of this research program is the development of a methodology for predicting the concentrations of motor-vehicle-generated air pollutants throughout and urban area as a function of local meteorology and the distribution of traffic. The results of this work are intended primarily to be used as a tool in planning activities to predict the pollution patterns in any urban region resulting form planned traffic changed or predicted growth. In addition, the model can be used in an operational mode for short-term predictions.

Our first goal has been the development of such a methodology for a quasi-inert pollutant such as carbon monoxide (CO). For the initial development we used available data from five cities having CAMP* air monitoring stations: Chicago, St. Louis, Denver, and Washington, D.C. The current status of this program is as follows:

• A working model for co has been developed.

• A field program, designed to fill gaps in the available data, has been carried out in San Jose, California.

• On the basis of these data, the initial refinement and evaluation of the model have been completed.

In this and following sections, the structure and capabilities of the basic model are reviewed, the results of the field program are reported, and the progress in the refinement and evaluation of the model is discussed in detail.

* Continuous Air Monitoring Program stations, run by the Federal Air Pollution Control Office, Environmental Protection Agency.
