ANALYSIS OF NOISE CHARACTERISTICS OF TRAFFIC FLOWS ON THE EXAMPLE OF KRASNODAR

Abstract

In this article, the authors consider the noise characteristics of traffic flows in urban conditions. The unevenness of traffic flows in time and space entails a change in noise effects on the environment. The main source of noise pollution is the internal combustion engine, which produces aerodynamic noise and structural noise. Noise level measurements are carried out separately for vehicles in motion and for stationary vehicles. The noise level is directly influenced by the mode of movement of cars, the speed of traffic flow, and the intensity of traffic flow. Deterioration of working and leisure conditions with a high level of traffic noise can lead to a decrease in labor productivity and the occurrence of nervous disorders. Therefore, the protection of the population from the noise generated by transport is not only of social, but also of economic importance. Purpose: to analyze the level of noise impacts of traffic flow in urban conditions. Method and methodology. The methods of observation, statistical analysis, and synthesis were used in the article. Results: noise level measurements were carried out on the selected section of the road network, and calculated data were obtained based on the declared characteristics of the traffic flow. Scope of application of the results: research activities to improve the environmental safety of the traffic flow.
