In terms of a systematic approach, till now it was not possible to investigate separately sea passenger terminals and the operation of ferry or cruise lines. So it is necessary to investigate their mutual influence, analyze the intensities, take into account the influence of the external environment and solve forecasting problems. This circumstance justifies the need to use new tools and models that allow analyzing the macro-level, consisting of all the ports in the region and the available ferry lines. For solving short-term forecasting problems, the class of polynomial problems has recommended itself well. But, when taking into account the mutual influence of the terminals and ferry lines on each other, the task becomes much more complicated. The discrete nature of the initial data, schedules of ship calls which need to be combined into a single array of data, comes to the fore in the study of processes. The process of functioning of an individual terminal with varying degrees of accuracy can be represented as a sequence of several typical design modes, each of which corresponds to a change in a certain set of characteristics and number of ship calls. But when solving problems at the macro-level, the article proposes to use optimization based on the circos plot. The construction of this type of diagram is associated with the fulfillment of certain boundary conditions, which makes it possible to define the boundaries of the region, to study and to form the completeness of the initial data. The object of the study is the interconnection of selected marine passenger terminals and the existing ferry lines. Based on the initial data, transformations were carried out and a circular (circos) plot of relations was constructed. Such diagram takes into account the analysis of the mutual influence of the terminals of one region. The obtained results make it possible to improve the quality of decision making, since a representation of the macro-level planning system of the «marine passenger terminals - ferry lines» is formed within the framework of the selected marine region.

There has been a significant increase in the role of sea ferry services today as well as a significant increase in the number of ferry vessels and passenger flow, which requires the development of new practical forecasting methods. The article proposes a new approach to forecasting, which is based on the integrated interaction of the systems «passenger sea port - cruise or ferry lines». This research focused on the regions of the Adriatic and the Baltic Sea and the existing network of cruise and ferry line routes. When studying this system, it was justified to use a new mathematical model based on practical simulation and models of the theory of discrete processes and systems. The proposed model is complemented by a discretization-based study based on the Kotelnikov´s theorem. To reflect the dynamics of changes in such a system, it is proposed to use new diagrams of the intensity represented by circos graphs (diagrams). The article discusses the practical importance of using new circos intensity graphs of sections to study the operation of the «marine terminal - cruise line or ferry line» systems based on real data on the Baltic and Adriatic seas. Based on the simulation results, a new system of corrective actions is proposed to improve the management of marine terminals. It presents new results which can increase the accuracy of the planning and decision-making process in predicting and planning the route network based on the research of passenger traffic between the «sea terminal - cruise line or ferry line» systems.

The article characterizes the growing interest of the Arctic states and the world community to the development of the vast natural resources in the harsh environment of the Arctic, including the development of programs and the strategy, the importance of international cooperation, harmonization of legal framework of economic activities in the macro-region. The essential modernization and development of transport and logistics complex in the effective development of the Arctic zone is substantiated. A conceptual model for creating the modern transport and logistics complex applicable to Murmansk transport hub, the largest in the Russian Arctic, has been developed.

Local authorities of Katowice have proposed to localize a transport hub of the Park&Ride system at Brynowska junction. The paper reviews the impact of this proposition on road traffic at the hub. The analysis of transport modal split was performed. In order to estimate the effects of such a system, an analysis of traffic distribution was done with a questionnaire survey. Based on the results, two traffic simulation models have been developed: first, simulating the current state of Brynowska junction and, second, presenting the junction with the transport hub of the Park&Ride system. A comparison of the two models made it possible to estimate the effects of the implementation of the Park&Ride system. Obtained results prove that this solution could improve the current state of the transportation system.
