Case study of noise pollution from vehicles and legal mechanisms for road noise control

Among the many environmental problems of the modern world one of the important ones is noise pollution. Currently, noise pollution from vehicles requires special attention in densely populated and industrial cities, as there is a trend towards an increase in the areas of acoustic discomfort in built-up areas. The noise that occurs on the roadway of the highway extends not only to the territory near the highway, but also deep into the housing development. Study' objective was to assess noise pollution from vehicles in the most densely populated area of Poltava (Ukraine), as well as to establish the possibility of influencing the situation through legal mechanisms to have an understanding of further research directions and ways to achieve a comfortable urban environment in Ukraine. The noise levels from traffic flows were measured in accordance with GOST 20444-2014, using the Testo 815. To determine the equivalent noise level from the traffic flows movement, an empirical dependence was applied in accordance with the methodology of the State Agency for Highways of Ukraine. Determined that the daytime threshold values are exceeded by 20–28.9 dB(A), which is not acceptable. The reasons for the increase in noise are the road bumps, a significant number of cars and number of stops and streets junctions, the movement of vehicles at a non-constant speed, lack of roadside landscaping. About 62,550 people live in areas where the noise level exceeds the permissible value for the area near residential buildings. The calculation method used turned out to be more accurate than the measured results and showed a significant effect of traffic intensity on noise pollution. Apparently, the low measurement accuracy is justified by outdated road noise measurement standards, which, in turn, need to be seriously revised. Reducing noise levels by optimizing traffic flows is one of the priority areas in which it is necessary to bring the environmental legislation of Ukraine. Ukrainian legislation still needs to undergo many changes to reach a level where it can be used as a control lever to achieve a safe ecological environment
