The transport accessibility of the Arctic zone is of strategic interest for Russia from the point of view of the possibility of mineral exploration and ensuring further systemic development of this part of the national territory.The objective of the study is to carry out a spatial analysis of the transport system of the Republic of Sakha (Yakutia), to identify its topological properties and restrictions that impede providing sufficient logistics services. Based on the method of spatial analysis, the conducted study of the state of the transport system of the Republic of Sakha (Yakutia) allowed to assess transport provision within its territory for three types of transportation: transport provision of internal regional (local) transportation, transport provision of accessibility (entry and exit) of the territory of the region, and transport provision of transit transportation across the region.The study showed that air transport is the main mode for passenger transportation, while seasonal water and winter road transportation are the main modes of freight haulage.The regions of Yakutia with access to traffic arteries and isolated from them have been identified. Calculations based on the Engel’s coefficient allowed to proceed with a mathematical assessment of the transport system of the region, which indicates its insufficient development due to the lack of year-round transportation routes in the areas of the Far North and the Arctic zone. The transport infrastructure of this part of the region are represented by seasonal winter roads and waterways, which prevents from assessing their general year-round potential. For its assessment, it is necessary to consider seasonal availability of each individual section of the network.
