Abstract: The subject of this research is the territory and practice of the assessment of the regional transportation systems pertaining to the regions of the North, where the absence of year-round land routes makes their comparison and analysis impossible. In the Arctic and Northern regions of Russia, the main transportation system consists in seasonal routes, which are not usually used in the practice of analysis of transportation coverage, accessibility and transportation potential of the territories. These tools are developed by the method of multivariate classification on the basis of multivariate median, taking into account both, a number of quantitative indexes, including the sum of seasonal routes and their productivity, as well as qualitative, which include the level of transportation costs. The developed methodological tools are based on the classic methods of assessment of the regional transportation system, but at the same time, contains novelty, as it accounts for the existence of seasonal types of transportation routes and their logistical component. This allows for a more comprehensive assessment of the peculiarities of development of the transportation systems in the Northern regions.
