Diagram of the street canyon scale model used, all measurements of the coordinate system are in mm. Gray boxes represent the cyclists, while dots indicate the position of the source during the experiments. Case 1 refers to the car positioned upstream of the cyclists in blue and Case 2 is when the car is adjacent to the cyclists in red. The wind direction indicates the wind incidence in the free stream.
