Abstract: This paper presents the basic principles of the method of calculating air pollution from road traffic in an urban built-up area. The algorithm of the method is based on the numerical integration of stationary two-dimensional partial differential equations of turbulent diffusion, with boundary conditions for the street canyons. The method consists of two modules: KALIB and STREETS, which calculate the distribution of pollutant concentration in a street canyon; and GRID and GRIDMAX, which calculate the distribution of pollutant concentration in the free atmosphere. The output of the method is given in numerical and graphical form.

Keywords: air pollution; calculation method; CO; emission factors; highway; NO_x; road traffic; street canyon; VOC.
