Abstract

Using the developed microscale mathematical model to study the distribution of vehicle emissions in street canyons, a study was made of the effect of footpaths raised or lowered by three meters relative to the roadway on the distribution of impurity concentration in the street canyon. The results showed that in both cases there is a multivortex turbulent movement of air masses, which worsens the process of weathering of pollutants from the street canyon.
