The Coastal Shipping Network in Greek Insular Space: Reorganising it Towards a “Hub and Spoke” System Using Matrices of Flows and Connectivity Matrices
This paper is based on the analysis of interinsular relations that have been shaped according to the existing coastal shipping network in the Greek insular space. It tries to contribute to the effort that was overwhelmed in the past few years for a more systematic investigation of the differentiation of the existing linear model of the coastal shipping network, with its modification into a “hub and spoke” model. The methods of analysis are based on the use of matrices of flows (coastal shipping origin-destination) and connectivity matrices, in which the direct connections are initially taken into consideration followed by the indirect ones between the islands. The insular area of the Kyklades prefecture in the Aegean Sea is the case study. The possible cohesive territorial units in the insular space of Kyklades, as well as the attainable nodal ports that may function in these units, are defined.
