Simulation and analysis of transport of gaseous wastes from automobile traffic with random characteristics

An approximate model of transport and dispersion of automobile waste gases by a transverse air flow is considered. The motion of cars is assumed to be a random Poisson process. One possible approach to estimating the concentration of the wind–transported waste and determining its statistical characteristics is described. The length of the representative section of a roadway that is sufficient for a correct analysis of the ecological situation is determined. The power of a linear stationary source approximating the distribution of the mathematical expectation of the concentration of wastes exhausted by a random flux of cars is evaluated.
