The issues related to the formation of sea traffic flows in the waters of the Northern Sea Route are discussed in the paper. The work is a part of complex researches, which are conducted at the Arctic Faculty of the Admiral Makarov State University of Maritime and Inland Shipping on the problems of navigation and hydrographic support of shipping in the Arctic. A list of the main directions on which the traffic flows in the Arctic seas of the Russian Federation are studying is given. It is noted that data of objective quantitative and qualitative control on the position of vessels and the parameters of their movement (speed, course, geographical position) underlie the study of traffic flows in the water area of the Northern Sea Route, like any other transport system. Vessel identification and objective control over the parameters of their movement with a given reliability, accuracy, completeness and frequency are achieved using automated satellite identification systems. The method of information collection , its processing and analysis of changes in the main quantitative indicators of the traffic flows in the water area of the Northern Sea Route, relating to the period from 2014 to 2018, is described. The results of the statistical data processing describing the change in the structure of the Arctic transport fleet, which forms the transport flow, are presented. The distribution of macroindicators of three groups of transport vessels is studied: group 1 ships with categories Arc7,8; Group 2 ships with categories Arc4,5; Group 3 vessels with categories of ice strengthening Ice 1,2,3, as well as vessels that do not have an ice category. The quantitative indicators characterizing the state of the structure of the Arctic transport fleet and the trends of its change are determined. The main directions of further research are outlined.
