We are working to close data gaps in freight transport and to develop digital replications of logistics systems, with the aim of providing a sound basis for decision-making in both practice and policy. To this end, we analyse the planning and operation of transport networks and investigate how different modes of transport, transhipment technologies, digital platforms and business models can be systematically integrated. Using interviews, surveys and simulation and optimisation methods, we demonstrate how productivity can be increased and existing capacities utilised more efficiently.
