Intermodal transportation is a specific function of the friction of distance, which has a stepwise structure depending on if what is being transported is in movement or being handled at a transport terminal or a distribution center. On the above graph, intermodal transport costs (C(T)) between an origin and a destination

Value Per Ton of U.S. Freight Shipments by Transportation Mode, 1993-2007
Source: BTS. When transportation systems are taken individually they carry commodities in accordance to standard transport economics; the value of what is being transported is related to the transport costs of the mode being used. Commodities strictly carried by rail have the lowest value per ton (e.g. coal, gain) while
North American Containerized Trade with Asia, 1995-2020
Source: UNCTAD, Review of Maritime Transport, various years. North American trade (particularly the United States) with several countries of the Pacific is systematically imbalanced, notably with China, Japan, and South Korea. These imbalances emerged during the 1990s. From an import/export ratio of close to 1 in 1995, this ratio surged
Containerized Cargo Flows along Major Trade Routes, 1995-2020
Source: UNCTAD, Review of Maritime Transport. Container flows are quite representative of global trade imbalances, which have steadily been growing since the mid-1990s. For instance, 3 times as many containers are moving from Asia to the United States (20.6 million TEUs in 2020) than vice-versa, meaning that the equivalent of
Container Usage during its Life-Span
Source: adapted from Crinks, P. (2000) Container Usage Asset Management in the Global Container Logistics Chain, International Asset Systems. Containers are built to be durable since they can be exposed to all possible conditions, from tropical to subarctic. They are also subject to potential damage when loaded, unloaded, transshipped, or
Stacked Upper Deck of a Containership
Photo: Dr. Jean-Paul Rodrigue, 2012. Stacking containers on a ship is a complex operation involving close interaction between the container yard, drayage operations between the ship and the yard, and crane operations. The above photo depicts a typical stacking configuration of different container sizes and types taking place on a
Common ISO Container Size and Type Codes
In 1995 an ISO agreement was reached concerning container marking codes that would depict the length, height, and type of container in a short and easy-to-read sequence. This sequence is composed of four letters or digits. The first element of the sequence is about the length of the container, with
