EN The paper proposes the 3-D nonlinear mathematical model for analytic determination of exhaust concentration dynamics in the city regions under the important stipulation that an airflow velocity is not a priory known. To determine an unknown airflow velocity the nonlinear mathematical model is proposed and this nonlinear model is solved by analytical method. In this model it is provided that the turbulent and molecular diffusion coefficient changes depending on the vertical remoteness above the ground surface. The proposed model can be used for solutions of operative problems on urban traffic organization, of long-term planning of urban agglomeration development and new highway building.
