Abstract:The dispersion models for the vehicle exhaust pollutant are classified as Gaussian model,empirical model, numerical simulation model and box model. Based on these classification, the kinds of models are described and their advantage are compared. Furthermore, the difficulty in developing the new model is indicated and the key problem is discussed.
Keywords:vehicle exhaust pollution  dispersion model  pollutant diffusion  street canyon  highway
