Laslov S. Improvement of methods for evaluating the parameters of noise protection screens on highways

The dissertation is devoted to solving an urgent scientific and practical problem - increasing the efficiency of the use of noise barriers on highways by improving the method of estimating the parameters of traffic flows. The mathematical model and methods for estimating the parameters of noise protection screens on highways have been improved, taking into account a set of factors, namely: constructive, geometric parameters of the screen and characteristics of the road, different traffic speeds and climatic conditions. A methodological approach to conducting experimental studies of the effectiveness of noise barriers of various designs on sections of public roads has been developed, taking into account their parameters, noise barriers, distances from noise sources to the places of measurement of noise load and damage to noise barriers. A methodology for experimental measurements of the noise load in the rural area when using noise barriers on highways has been developed. The basic principles of environmental protection from the noise load caused by the traffic flow on highways are proposed. Recommendations for improving the efficiency of noise performance of existing screens on Ukrainian highways have been developed and an improved noise-absorbing screen design with improved noise protection and strength parameters has been proposed. Recommendations for the design of noise barriers on public roads have been developed, which include basic requirements for barriers, architectural and landscape, planning and design solutions, and requirements for the construction and materials of noise barriers.
