A model of particle dispersion when there is a crosswind was created on the grounds of the Gaussian distribution of particles over a road. When the wind is absent, a cylindrical cut-shaped whirl of dust immediately changes into a cylindrical one with a cut-off of the ground dust cloud. Later, when the wind blows perpendicular to the road, the particles are carried to the roadside. The source of particles is not only the emissions from automobiles, but also sources related to the automobiles (tyres, brakes, etc.). The particles and aerosols are grouped into two groups with average diameters. A good congruence of the regression equation obtained by the theoretical expression and the experimental data shows that the particle distribution scheme described in the model fits very well.
