We conducted wind tunnel experiments with simple-shaped block models to study the relationship between the widths of connecting streets across a street canyon and the flow and concentration of roadside air pollution within the street canyon. The main results are as follows: 1) The concentration in the vertical section along the central part of the street canyon increases as the widths of gaps or connecting streets decrease. 2) The vertical concentration distribution within the connecting street implies the existence of a vertical vortex, which was pushed outwards from inside the street canyon. 3) The lateral flow parallel to the main street greatly affects the concentration in the connecting streets.
