The purpose of this paper is to present an outlook on the future research for a specific mixed model
transportation network referred to as Foliated Transportation Networks (FTN). FTN is thus far a
conceptual model that is based on the idea of foliating a direct shipment and a hub-and-spoke structure in
order to achieve higher fill rates without an increase in the total traffic work at the same time. The
conclusion is that the two principal areas of research are areas of planability (i.e., the ability to in advance
and on a sufficient level of detail and precision determine the capacity requirements of the system) and
network optimization (i.e., the optimization of the distribution of goods and resources between the
different layers of the network).
