Research of acoustic discomfort and pollution environment by increased flow motor transportation in the south district of Belgorod

Introduction. The present time is characterized by the rapid development of cities and, as a consequence, the aggravation of a whole set of problems. Cities provide a fairly high standard of living for the population, satisfy their needs, but at the same time, they are the center of the significant environmental problems. All this is due to the excessive concentration of transport and economic facilities in relatively small areas. Goals and objectives. The aim of the work is to assess the level of impact of vehicles in terms of noise pollution and air pollution in Belgorod Construction of noise maps of individual microdistricts of Belgorod and calculation of emissions of the main pollutants into the air from traffic flows, which will make it possible to predict and identify areas of the urban environment where the established sanitary and hygienic standards are exceeded. Methodology. The study of the noise situation in certain areas of the city was carried out in accordance with the requirements of GOST 20444-2014 and GOST 53187-2008. The main characteristic was the equivalent sound level of traffic flows, calculated from the results of instrumental measurements of the noise level. To assess air pollution, calculations were carried out according to the methodology for calculating emissions of pollutants into the atmosphere by vehicles on city highways. Field observations to study traffic flows were carried out in the daytime. Results and its discussion. The obtained data on the noise level on the territory of the studied microdistrict were used to compile a noise map, which makes it possible to identify areas of the urban environment that do not meet sanitary and hygienic requirements for the noise factor. Calculation data for emissions of harmful substances from vehicles can be used to create environmental passports and are useful in making decisions to reduce the negative impact of transport on the environmental situation of industrial cities. Conclusion. The study of noise pollution and atmospheric air pollution, the source of which is motor vehicles, in an urban environment, makes it possible to develop a complex of health-improving, environmental, urban planning measures and a number of architectural and planning solutions aimed at reducing the level of noise pollution and air pollution in these areas.
