It is important to know how car exhaust pollutants are formed and how they are distributed in natural environment. This paper presents a numerical model of a short-term dispersion of pollutants caused by vehicles which moves with changeable velocities. A cross-road with channing traffic lights is considered here. Each vehicle is treated as one point source of pollutants and the values of emitted pollutants, depending on vehicle speed, are described by individual characteristics of vehicle engines. The Gaussian mathematical model for instantaneous moving point source has been applied. The turbulent zone is taken into account in order to estimate the dispersion coefficients. In the model, the wind speed and its direction, which influence the ...
