Deliverable D3.7 focuses on analysing and optimising European macro transport flows (based on Eurostat data from 2015). It provides insight of the cost and CO2 savings potential of several scenarios applied to European transport flows. Moreover, it shows the potential in the European network for collaborative transport between intermodal logistics clusters, i.e. agglomerations of several types of firms and operations (logistics service providers, logistics operators, linked logistics industries and manufacturing). Furthermore, it indicates the benefits of collaborative transport with respect to increased transport efficiency and multimodality and as a result decreased costs and emissions.
