Description	The objective of this study is physical modelling of emissions from vehicle exhausts in street canyons within an urban area and the influence of the approach flow direction on contaminant spreading. The requirements of the similarity of the atmospheric boundary layer and a boundary layer in the wind tunnel are satisfied. For several flow directions mean velocity and concentration fields are measured within street canyon intersection inside symmetrical urban built-up area. Scalar fluxes are computed from measured data to quantify pollutant spreading. Results of the experiment show a significant sensitivity of the mean velocity field on the approach flow direction. The approach flow extensively influence contaminant spreading within the built-up area and therefore intensity of street canyons ventilation vary with the approach flow direction. The approximate flow direction with the most favourable dispersion conditions in the studied area is found out.
