This paper analyses the effectiveness of policy measures aimed at triggering a modal shift in the freight transport market. The analysis is based on the inventory-theoretic framework that studies modal choice from a business logistics viewpoint. The crux of the inventory-theoretic approach lies in the fact that explicit attention is paid to all costs in the supply chain that are affected by the choice of transport mode. After a brief literature review on the inventory-theoretic framework, the framework is used to calculate the market shares of different freight transport modes for a hypothetical transport market. In a second step, the impact of some policy measures on the market shares of the transport modes is calculated. By way of illustration, the analysis is applied to the market for container transport from a seaport to its hinterland. It is shown that a combination of certain policy measures can lead to significant modal shifts from road transport to intermodal transport.

Since 1990s the liner shipping industry has faced a period of restructuring and consolidation, and been confronted with a continuing increase in container vessel scale. The impact of these changes is noticeable in trade patterns, cargo handling methods and shipping routes, in short 'operations'. After listing factors influencing size, growth in container ship size is explained by economies of scale in deploying larger vessels. In order to quantify economies of scale, this paper uses the liner service cash flow model. A novelty in the model is the inclusion of '6000-20-foot Equivalent Unit (TEU) vessels and the distinction in costs between single and twin propeller units on ships. The results illustrate that scale economies have been Á and will continue to be Á the driving force behind the deployment of larger container vessels. The paper then assesses the link between ship size and operations, given current discussions about the increase in container vessel scale. It is found that (a) ship size and operations are linked; (b) optimal ship size depends on transport segment (deep-sea vs. short-sea shipping, SSS), terminal type (transhipment terminals vs. other terminals), trade lane (East-West vs. North-South trades) and technology; and (c) a ship optimal for one trade can be suboptimal for another.

Supply chains, logistics and freight have been facing increasingly complex challenges posed by transitions in economic structures, urbanization, city design and transport systems, as well as by the externalities associated with logistics activities in urban areas. This has driven a great deal of research recently. Yet, there are no sufficient contributions clarifying the current state of thought in this field. This article critically reviews the literature highlighting current approaches in the field. The objective of the article is threefold. First, to provide a framework with geographical and functional elements of urban logistics. Second, to identify the scope of the literature, vested into a typology. And third, to define the terms that may embrace the various analytical interests of the urban logistics field, namely city logistics, urban goods distribution and last mile logistics. The aim is to contribute to organize the current and future thought in the field of urban logistics.
