    The flow and gaseous dispersion emitted from motor vehicles in urban street canyons were experimentally simulated in a boundary layer wind tunnel under neutral atmospheric conditions using a tracer gas emitted from a line source without buoyancy. The flow and diffusion fields in the urban canyons were examined for three street configurations: (1) Regular-shaped intersection, (2) T-shaped intersection and (3) Skew-shaped intersection. Details of the flow and dispersion field were reported that includes the structures of the mean flow field, turbulence intensity, turbulent kinetic energy, Reynolds stress and concentration of pollutant emissions.
