Motor vehicles emissions as an example of technogenic hazard on urbanized areas

Abstract

Road transport is a necessary part of the urbanized area. However, at the same time it represents a technogenic hazard. In the process of movement, as well as at each stage of the life cycle, motor vehicles pollute air, water and soil. There are also possible road accidents involving cars, accompanied by explosion, fire or fuel spill. This paper calculates the amount of pollutant emissions from motor vehicles at crossroads in the Ufa city based on experimental data. Three most problematic crossroads of the city are analyzed: two in the center and one in the industrial part. For reducing the amount of emissions, proposed to construct an underground tunnel at the first crossroad and underpasses at the other two crossroads. As a result of solutions implementation amount of pollutant emissions at crossroad No 1 can be reduced by 13.4%, at crossroad No 2 by 3.4%, at crossroad No 3 by 4.2%.
