Evaluated Mapping of Noise Pollution of Urbanized Territory

Abstract

Due to the acceleration of scientific and technological progress in the word, the level of traffic flows, industrialization, thenumber of automotive and technical equipment of the urban economy has increased, as a result of which people are constantlyexposed to high-intensity noise. However, few people know that, by its effect on the human body, noise is more harmful thanchemical pollution. Constant exposure to noise not only reduces hearing, but also causes other harmful effects – ringing in theears, dizziness, headache, increased fatigue. People working in noisy conditions have an increased level of neuropsychiatricdisorders.The article discusses the algorithm for evaluative mapping of noise pollution in the settlement area, which will ensurebringing the city territory to sanitary standards. The resulting noise map, which should be part of the master plan, captures thecurrent and future state of the noise regime in the city. Accurate noise maps require the analysis of large number of differentnoise sources and, as a result, are very costly, although in most cases only an estimate of the noise loading is required.Therefore, it is advisable to build a hierarchy of noise sources and take into account the most significant. Such the mostsignificant source of noise in settlements, as a rule, is a road network - streets and lanes on which movement of auto transport isallowed. The procedure for creating a geospatial model of noise pollution in the environment of a geographic information systemdescribed in the article includes creating a multibuffer for each noise source, translating the resulting vector image into a rastersurface, superposition of individual object noise rasters, and creating an integrated evaluated map. Formed ways to improve thenoise situation based on the results.
