Abstract:
In order for transportation planners and engineers to evaluate the air quality impact of a proposed project, mathematical means are required to describe the dispersion of air pollutants from a line source. CALINE2, the California Line Source Dispersion Model, is presented and discussed as one such mathematical approach. CALINE2 is based on the generalized Gaussian dispersion theory, and simulates the dispersion of carbon monoxide from a uniform line source. A sensitivity analysis of the model relates the behavior of its predictions as a function of the input parameters. A preliminary verification study using carbon monoxide data from the Los Angeles region gives the user an estimate of CALINE2's predictive capabilities. An earlier version of the model, which was distributed nationwide in 1972, is compared with the present version.
