Abstract

The research focuses on the theory and practice of assessing the transport accessibility of the territories of the Northern regions, where the absence of year-round ground communications makes it impossible to compare and analyses them. The consideration of seasonal lines of communication is justified by the lack of alternatives in the regions of the North. The conducted analysis of the spatial pattern of the transportation network in the Republic of Sakha (Yakutia) revealed the heterogeneity in the transport accessibility of the municipal districts of the Republic. The results of analysing the level of differentiation of transport accessibility of municipal entities performed by various techniques show a diverse differentiation, which is influenced by the vastness of territories, the small number and very dispersed allocation of inhabited localities in the Arctic regions and a number of other factors. The developed methodological framework has features of a novelty, since it takes into account the presence of seasonal types of transportation lines in the Northern regions of the country and their logistical component that makes it possible to consider the specific features of transportation systems in the regions of the North to the fullest extent.
