The Academic Literature on Intermodal Freight Transport

It is widely accepted that non-road freight transport is less energy intensive than freight transport by road. The use of other transport modes than truck for long haul freight transport can therefore contribute to more energy efficient transportation systems. As a result, the successful promotion of intermodal transport, using rail or sea on the long haul part, has been identified as the most critical action to achieve a sustainable transport sector. The aim of this paper is twofold. First, we examine the historical development of academic research on intermodal freight transport. Second, we identify the seminal works on the topic. In our analysis we identify and classify the academic literature on intermodal freight transport. This approach has also previously been used to aggregate knowledge about particular fields of research and it aims to be as unbiased as possible by being auditable and repeatable. A timeline on the evolution of the academic literature on intermodal freight transport is presented and the development in publication frequency and topics are commented on in relation to keywords, journals, author affiliations and countries. Publishing frequencies are measured, and reported, both in terms of absolute and relative values. Finally, what is likely the most important and influential papers on intermodal freight transport are identified, using citation frequency.
