The study of envorinmental state on road intersections based on emissions of car engines in Zhytomyr

This paper presents results of the studies of environmental conditions on road intersections based on car engine emissions in Zhitomir. Statistical methods were used to determine the intensity of traffic flows based on transport emissions according to video monitoring records. Intersections with the highest intensity of traffic flows, where there is a high risk of car emissions accumulation above the applicable standard, were chosen for the assessment of ecological sustainability. Calculation of pollution was done for the intersection ofNebesnoi Sotni street andM. Grushevskogo street. The results of calculation were compared with the limit of affordable concentration and conclusions that emphasize difficulty of the problem and the emergence of its solving. The system of ecological safety inZhitomir requires significant improvements taking into account the exceeding of factual values of pollution over normative values. Recommendations concerning of ecological sustainability of intersections can be developed through the optimization of traffic flows with the use of intellectual traffic systems.
