Abstract:

A detailed computer analysis of air quality for a complex highway interchange was prepared, using an in-house version of the Environmental Protection Agency's Gaussian Highway Line Source Model. This analysis showed that the levels of air pollution near this interchange in the year 1978 would not exceed established standards.

This analysis is treated as a case study, illustrative of methodology which is useful for computing air pollution levels associated with many highway configurations. The individual ingredients of the analysis are described in detail, including the handling of road geometry, the calculation of emissions, the estimation of meteorological parameters and the selection of receptor locations. A complete listing of the computer program used in these studies is included.

It concluded that the air quality analysis methodology developed for this case study is an easy-to-use, straightforward procedure of general applicability. Within the limitations of the model and subject to the accuracy of the input data, this approach can produce reasonable estimates of worst case pollutant concentrations for comparison with national ambient air quality standards.
