COMPARATIVE ANALYSIS OF HIWAY, CALIFORNIA, AND CALINE2 LINE SOURCE DISPERSION MODELS

This paper provides a comparison of three different, idealized line source dispersion models--HIWAY, California Line Source, and CALINE2--that predict carbon monoxide concentrations near highways. All are based on the Gaussian dispersion equations and are compared by means of sensitivity analysis and model validation. The sensitivity analysis analyzes the dependence of normalized pollutant concentration on variations in several independent input parameters such as stability class, wind angle with respect to the highway, and receptor distance from the highway. The models are validated by comparing carbon monoxide concentrations measured near a highway with concentrations predicted by the models. /Author/
