New Gaussian vertical dispersion curves for the first 100 meters downwind of a freeway are proposed. The validity of assuming a vertical Gaussian distribution of pollutants near the freeway is examined. Results are given which indicate that traffic induced turbulence dominates at the point of emission, but that daytime variations in traffic flow have a negligible effect on the initial mixing of the pollutant at the source. Residence time within the 'mixing cell', as determined by ambient wind speed, controls the initial amount of mixing that occurs.
