Modeling transportation demand in short sea shipping

Abstract

A b s t r a c t The objective of this study is to develop a generic model for evaluating the potential demand for short sea shipping (SSS) in a given route. This model can be used in feasibility studies for novel SSS services, when shipping companies evaluate the potential demand for the service, considering the amount of cargo carried between regions and the potential for modal shift from road to sea. A model of costs and transit time across the entire supply chain is developed for unimodal and intermodal transport solutions based on cargo ro-ro ships. The model includes decision-making criteria on the preferable transport solution. The model is applied to the route between Leixões and Lisbon, for which the overall demand for cargo transport is obtained from statistical data relating to exports and imports split by NUTS 2 regions. 1 The model produces the amounts of cargo that could potentially be carried annually through each transport solution, for different freight rates and ship speeds, and allowing the identification of NUTS 2 regions for which the SSS solution is competitive. A sensitivity analysis is carried out to assess the effects of changes in several model parameters on results.

Numerical Modeling of Air Pollutants and Greenhouse Gases Emissions in Intermodal Transport Chains

“…Furthermore, two different emissions scenarios are chosen for these transport chains between Portugal and northwestern Europe. The Iberian Peninsula has significant volumes of trade with central European countries; therefore, this corridor is a suitable candidate for achieving substantial modal shifts from road to sea [41]. Concerning the geographical regions in the study, it is also worth pointing out that the English Channel and North Sea form an ECA and, therefore, have stricter emissions control standards both for SOx and NOx.…”

Integrating Short Sea Shipping with Trans-European Transport Networks

“…Accordingly, the time and cost particularities of intermodal transport chains based on SSS in the corridor from the Iberian Peninsula to Northern Europe have been studied [18,19] The first paper includes a methodology for modelling demand in SSS (using Ro-Ro ships), which allowed the estimation of cargo volumes in the route Leixões-Rotterdam, while the second presents a multicriteria approach to select the most convenient ports for establishing SSS services in the same corridor. The methodology in [18] involved the evaluation of preferences for SSS or road transportation over a set of pairs O/D, considering both time and cost as decision parameters. These results were later used to size the required Ro-Ro ship for this route and estimated cargo volume [20].…”

Instruments Used in Short Sea Shipping Research between 2002 and 2019

“…Number sixth research area covers potential demand, opportunity, competitive advantage and sustainable transport development ( [38], [69], [101], [50], [90], [124], [32], [75], [110], [94], [74], [111], [70], [71], [58], [59], [109], [128], [119], and [126], [99], Eventually, only few studies can be traced that focus on the influence of meteorological or weather conditions on SSS operations ( [43], and [29],).…”

“…The conclusion of this study shows that along the Atlantic facade of the Iberian Peninsula, there are growing nodes with great potential to enable the increase in their throughput, in terms of inner competitiveness or by establishing new SSS services between neighboring positions. [109] also employed the Costs and Transit Time model to investigate a modeled transportation demand in SSS. This model produces the amounts of cargo that could potentially be carried annually through each transport solution, for different freight rates and ship speeds.…”
