Seeking new strategic options for promotion of intermodal transport in perishables: the use of Short Sea Shipping

The objective of this study is to find new options for the promotion of intermodality, based on short sea shipping, as applied to perishable products. At present, most of the transport is carried out by refrigerated trucks. In theory, this change would have positive effects on the environment and could even reduce transit costs, but companies are still hesitant to implement this practice. In this context, the present study aims to determine whether there are aspects other than operational considerations (e.g., time, cost, quality or environmental concerns) that condition modal shift. First, a literature review is conducted which attempts to identify both the strengths and weaknesses of intermodality in perishable transport. This review serves as the basis for the elaboration of a questionnaire targeting transport actors within the fruit and vegetable supply chain in southeastern Spain – the area taken as an application example. Next, the survey is used to determine the possible drivers that would favor a modal shift applying a structural equation analysis, corroborated with a traditional econometric model. As a result, the design of an overall strategy based on the creation of redistribution hubs at destination (i.e., located at ports), whose operations could be optimized through the digitization of the supply chain, appears to be a promising approach.
