The purpose of this article is to offer a literature review on the development and classification of inland terminals, later defined as “dry ports”. The aim of the paper is to analyze the extant literature on dry ports focusing on their concept, classification, function and technological processes. The review offers an updated structured approach to what is currently defined as a dry port. To this end, a structured keyword search in major electronic databases has been conducted to find related material. As there are many different names indicating dry ports in European, South East Asian and North American countries, the following keywords were used: “dry port”, “inland terminal”, “freight village” and “interporto/i”. The search was conducted in respect of the article title and text, abstract and keywords. The results show that there is no unanimous consensus concerning cataloguing of terrestrial nodal facilities serving port gateways. “Dry ports” have emerged as fundamental elements of the integration between the sea “system” and the land network. The increased interest in the genesis and development of dry ports has been accompanied by an abundant contribution of the scientific community, originating a thriving literature, which, however, does not find a common denominator.

The modern distribution of goods is highly complex, as it supports a closely linked globalized world. In the development of port terminals, competition is no longer only at the level of services. The increase in maritime transport and demand/supply in the hinterlands, with ensuing problems of capacity, distribution and movement, have called for renewed attention on adequate structures and infrastructures. This evolution, enabled by technology, commercial interests and public policies, can be considered as a stage in the ongoing development of containerization and intermodal transport. At this stage, it is important to consider port terminals and maritime navigation networks as a system, together with terrestrial goods transport. Increasingly, regions are developing so-called dry or inland ports, to better serve the demand. We set out to define a sustainable model for dry ports, beginning with a review of relevant literature focused on Italian, Dutch and selected USA examples. We first define dry port, in the context of intermodal transport, ports in general and inland ports. Our investigation led to the identification of management tools and best practices. We report on visits and interviews to selected inland ports and identify key dry port activities, applications of innovative technologies and implications for different modes of transport. For the three countries studied, we identify strengths and weaknesses related to infrastructure, structures, internal organization of yard, types of imported and exported goods, transport methods and related travel times and costs. In regards to resilience and sustainability, vulnerabilities such as congestion, climate issues and cyber-attacks are considered. Finally, a maturity model for assessing dry ports is proposed.

The authors intend to suggest an interpretation of dry ports as functional organs of a larger facility, known in Italy as “interporto,” with reference to an Italian reality. This research fills a gap in literature as to the authors' knowledge. There is lack of research on the dry port concept, and this is the first chapter presenting this concept in an interpretation “functional” to the co-modality model of an “interporto.” The chapter firstly aims at contributing to finding possible contact points between what has up to now been defined as “dry port” and the concept of “co-modality.” The following section briefly defines the characteristics of a facility such as “interporto.” Then the connections between recent developments in shipping and in terminal business and the increased role of dry ports in the value chain are explored. Finally, the authors suggest challenges and opportunities for further study and draw their conclusions.
