The Tokyo Metropolitan Government (TMG) model is one of the dispersion model for automobile emission, which is based on the Gaussian plume model. The original TMG model has a tendency of overestimation under parallel wind direction and low wind speed condition. The purpose of this study is to improve the original TMG model. The refinements of this model are inclusion of the traffic-induced turbulence and the shear flow correction. Calculated concentrations by the original and modified TMG models are compared with the air tracer diffusion experimental data. Good agreement is obtained between the measured and calculated concentration-downwind distance profile. The correlation coefficient for measured and calculated by modified TMG model is 0.87.
