Numerical Study of Traffic Pollutant Dispersion within Different Street Canyon Configurations

Table 2

Summary of three kinds of street canyon configurations. 𝐻 is the height of building in the wind-tunnel experiment; namely, 𝐻 = 0.12 m. 𝐻_𝑢 and 𝐻_𝑑 are the heights of the upstream and downstream building.
