Abstract

Traffic pollutant dispersion processes inside urban street canyons with avenue-like tree planting have been studied in wind tunnel experiments. Tree planting of different crown porosities and their effects on the pollutant concentrations at the canyon walls have been investigated for wind approaching perpendicular to the street axis. The results show that avenue-like tree planting in street canyons lead to overall increases in traffic originated pollutant concentrations in comparison to the tree-free reference case. Maximum increases in concentrations of 80 % have been measured at the building walls in the street canyon central part where the dispersion processes are affected strongest by tree planting.
