Abstract
Introduction. The level of concentration of toxic substances in the atmospheric air of main streets is largely determined by their aeration regime, established due to exposure to air flow of buildings and green spaces. Therefore, when developing master plans of cities and projects of detailed planning of residential formations to ensure hygienic standards for the expected content of emissions of motor transport in the air of transport communications and adjacent residential buildings, the influence of urban factors on wind speed and direction one should take into account.
The aim of the study is the justification and selection of urban planning measures to reduce atmospheric air pollution from main roads and streets by exhaust gases of motor transport.
Material and methods. Full-scale surveys of transport infrastructure facilities in large cities and modelling of the processes of dispersion of exhaust gases of cars in the air using models of residential buildings and green spaces.
Results. The regularities of the formation of the aeration regime of city streets and the dispersion of car emissions behind the landscaping strips and in residential buildings have been established. Optimal variants of planning, development and landscaping of main streets have been determined, ensuring the reduction of gas contamination of pedestrian zones, public spaces and residential areas.
Limitations. The choice of landscaping objects for urban roads and streets for field observations and modelling of car emissions dispersion processes is limited to strips of green spaces of a blown and dense construction, without taking into account the peculiarities of the transformation of the air flow and reducing gas pollution under the influence of landscaping strips of an openwork design.
Conclusions. Reduction of gas pollution of main roads and streets is ensured by choosing the direction of the route and planning, and building techniques. At the same time, it is necessary to use environmental protection linear-strip landscaping facilities of optimal design. At the same time, it should be borne in mind that frontal multi-sectional buildings and strips of green spaces of windproof dense construction stimulate the appearance of stable vortices with a closed circulation of impurities in street canyons and on sections of highways. When choosing urban planning solutions to ensure the quality of atmospheric air of transport communications and adjacent residential buildings in various landscape and climatic conditions, it is necessary to take into account the specifics of the tasks arising in this case to regulate the aeration regime and reclamation of the microclimate as a whole.
Compliance with ethical standards. The study does not require the submission of the conclusion of the Biomedical ethics committee or other documents.
