“…This insight has already been highlighted by Bouchery and Fransoo (2015) who state that high volumes and short PPH distances make intermodal transport attractive on short and medium distances. The importance of short PPH distances in terms of intermodal competitiveness, especially from the perspective of externalities, has also been underlined in Mostert and Limbourg (2016). The conclusions of Janic (2008) showing that, in some cases, the internalization of external costs may lead to a lower attractiveness of intermodal transport, rather than when only operational costs are considered, reinforces the need for particularly considering short PPH distances.…”
