The aim of this study is to develop a simulation method for predicting the wind environment and turbulent diffusion process, which are affected by moving automobiles within the real situation of urban street canyon, based on the methodology of canopy models. In the current investigation, a simulation method to reproduce the aerodynamic effects generated from the moving automobiles, namely 'Vehicle Canopy Model', was developed. In this study, wind tunnel measurements of flow over vehicle canopy and the drag forces caused by the car-shaped roughness elements with different densities were carried out. By comparing the results of CFD predictions of the developed 'Vehicle Canopy Model' with experimental data, the accuracy of the developed model was examined.
