Abstract: The aim of the present work is to develop a simple model in order to calculate the vertical pollutant distribution inside a street canyon at low wind speed. It is aimed at providing a relationship between traffic emission and the pollutant in excess. It is assumed that street ventilation is controlled by the vertical turbulent diffusion. The diffusion coefficient K_z must be known. In the present study, the correlation between calculated and experimental values will be shown, which makes it possible to estimate this parameter.

Keywords: street canyon; traffic pollution; turbulent diffusion.
