The mechanical process of transfer and dispersion of the exhaust gas near
a motor road has been studied based on the hypothesis of a stochastic traffic
flow on the considered roadway section, which is described by a Poisson
process with a constant intensity. Using the three-dimensional diffusion
equation, solutions have been obtained for problems on the concentration
distribution of pollutants near an extended roadway and a road crossing.
Basic stochastic characteristics of the concentration distribution
of the exhaust gas from a stochastic traffic flow have been determined.
Calculated results have been compared with experimental data.
