Measuring Connectivity for Domestic Maritime Transport Network

Abstract

This paper discusses several approaches to measure the connectivity of maritime transport. The graph theory-based approach, which is infrequently appeared in maritime transport literature, is firstly explored. However, since the graph theory does not take into consideration distance, cost or other obstacles, this paper thus presents the gravity-like model that considers the potential and impedance properties of maritime transport components. To get more comprehensive result relating to the connectivity index, the modified Liner Shipping Connectivity Index (LSCI) is proposed by changing the perspective of analysis as well as the key components to fit with domestic maritime transport. The application of methods is then demonstrated to the actual maritime transport network in Indonesia. As different with the similar work on the connectivity index for maritime transport that mainly takes into account the freight transport perspective, this paper also gives attention on the passenger perspective by pointing out the pioneer shipping.
