This paper presents an extension of the classical 4-step freight modeling framework with a logistics chain model. The logistics chain model translates trade flows into transport flows by creating logistics chains from the production regions to the consumption regions. The model assigns trade flow to the logistics chains, which may involve intermediate stops at logistics facilities such as distribution centers and warehouses. An aggregate multinomial logit discrete choice model is used to determine flow volumes for each of the possible logistics chains. Using the European trade flow and transport flow data, the authors show that the logistics chain model can translate trade flows into transport flows with sufficient accuracy. The authors present the results on the fit between estimated and control transport flows together with the estimated model parameters. The authors conclude that the logistics chain model can be used in industrial scale modeling suits bridging the gap between trade distribution and network assignment sub-models.
