Port connectivity indices

In recent years, there has been important interest in the development of connectivity indicators for ports. We present a methodology for gauging the RoRo connectivity of ports and exemplify its use through an application to European RoRo shipping. We show that in terms of RoRo connectivity, neither the number of links nor the link quality strongly dominates the results of our proposed indicator.

What does port mean in shipping?

Port connectivity indices: If you look at the portals in the dictionaries, you will encounter the word “port” and “entrance”; the port of call also has the same meaning; entering a sea which is in the sea or land, and the place of arrival and departure of the goods, the strap or the port. In other words, the port is included in the transportation of many places, as well as places including ports and terrestrial and air terminals. Goods are loaded and unloaded by sea or wet cargo ships by airplanes inland ports and terminals. In rail transport, you will also encounter a port word, which does not matter, and freight trains on these ports are either loaded or unloaded.

 

Introduction

Port connectivity indices: Maritime transport is vital for trade. Relevant EU initiatives include TEN-T, Motorways of the Sea, and Marco Polo I and II. One of such measures is port connectivity. Connectivity is a relevant performance indicator for port authorities. Shippers have large volumes and charter and fill complete ships and thus do not depend on pre-determined routes and networks.

The relative importance of the components

Port connectivity indices: LSCI works with five components, each of which carries equal weight. The weight could be analyzed by taking the effect of these four components on the generalized transport costs of all port users. This is instinctive, given that the number of terminuses that can be reached is a key to the connectivity of a port. The port-level connectivity can be extended to region-level or country-level connectivity in a frank manner.

 

Port connectivity indices: Data collection

The starting point of the data collection is the list of EU core ports that offer RoRo services. This definition explicitly excludes the shipping services offered by car carriers, as these serve a completely different market. A common of the RoRo services are used by passenger cars as well as trucks. The selected time span for the collection of data on the RoRo services was Mid-August of 2015. We downloaded the complete schedules for each of these service providers. We used real-time relocation of individual vessels through AIS to calculate the exact routing of each schedule. In the large majority of cases, both sources provide estimations within 5 %. Note that all the routes used in this paper come from published schedules.

 

Port connectivity indices: Conclusions

RoRo connectivity indicator is similar to formerly developed indicators dealing with maritime container connectivity. The relevant components of a RoRo connectivity indicator differ from those of a container connectivity indicator. In this article, we have introduced the notion of diminishing returns to the mechanisms of connectivity. The latter requires repeating this method in the coming years. We show that the connection Helsinki-Tallinn has the highest link quality. This illustrates the effect of the diminishing returns to scale on link qualities. Tracking the RoRo connectivity indicator in time will enable richer insights, of which the ones put forward in this paper are the first step.
