Sheludchenko L. The theoretical basis and methods of ensuring environmental safety of road networks

Dissertation for the degree of Doctor of Technical Sciences in specialty 21.06.01 "Ecological safety". Thesis defense will take place at the meeting of the dissertation Council D 26.880.01. State Ecological Academy of Postgraduate Education and Management, Kyiv, 2020. Specialized Academic Council D 26.880.01. The dissertation is devoted to theoretical generalization and solution of the actual scientific and practical problem, which consists in increasing the levels of ecological safety of naturally-technogenic geo-ecosystems with high density of road networks and improvement of the state of the landscape components of the environment within the limits of the reserve technological lanes (lanes of influence) of highways. The minimum value of density (traffic intensity) of motor vehicles is established, in which the regime of free movement of the aggregate of physical motor vehicles acquires the signs of their collective synchronized movement in the composition of the motor transport flow and the functional dependence between the volumes of dust emissions produced by motor transport streams and the degree of dispersion of disintegrated structural materials of motor roads coverings. The typical variants of object-oriented graph-analytical models of stratification of surface atmospheric layers within the limits of reserve technological bands of highways for various landscape conditions of natural technogenic geoecosystems are developed and processes of atmospheric mass transfer of pollutants in the territories adjacent to highways are investigated, depending on the characteristics of the landscape of the landscape naturally-technogenic geoecosystem and structural parameters of the road profile. Based on the modeling methods of the vehicle frame support frameworks, optimal constructional parameters of cross-sectional profiles of the reserve and technological lanes of motor roads of various categories and corresponding systems and objects of engineering protection of roadside landscapes were determined, and the procedure and algorithm of project management of natural-technological geoeosystems with developed motor transport networks was proposed. Key words: environmental safety, road network, traffic flow, landscapes, emissions, pollutants, migration processes, landfill processes, modeling, projects.
