This paper provides a comparison of carbon monoxide concentrations measured near a highway with concentration predictions from two different idealized line source dispersion models. The models are based on the Gaussian dispersion equations. Field measurements were made of carbon monoxide, meteorological conditions, and traffic conditions synchronously. The meteorological and source strength measurements were used as input to the models and the carbon monoxide data were compared to model predictions. Two empirical models were also developed. One model relates the ambient concentration to three parameters--the pollutants emission rate; normal wind speed; and the distance from the highway. The second model relates the ambient concentration to the pollutant emission rate, the intensity of the turbulent wake induced by moving vehicles, and the time of travel of the wake downwind.
