Abstract

The known static and dynamic wind speed influence models on the urban air purification degree from CO emitted by urban transport are analyzed. Three optimization problems of adaptive motor transport traffic organization of are formulated and solved on the dynamic model. It is proposed to introduce a control function for the total emitted amount of wind speed CO depending. The optimal function type is calculated, at which the pollutant rise height reduced to a minimum. The solution of the second optimization problem made it possible to determine those most unfavorable conditions, at which the safe distance to highway for a nearby settlement can reach a maximum. As a result of solving the third optimization problem, it is shown that the minimum average value of CO concentration at a certain height can be achieved with a certain dependence of wind speed horizontal component on the height of point under consideration.
