Intermodality is so broad that it is difficult to encompass all of its aspects in a single volume of reasonable size. Consequently, the author has attempted to touch briefly on as mnay aspects as possible, but has placed greatest emphasis on land-sea and air-surface cargo transfers. Intermodality can be observed from viewpoints of mode, type of cargo, condition of cargo, category of terminal, or combinations and permutations of these viewpoints. Each offers a different perspective to make up the total evolving picture. In this book, the author presents not just a statement of the status quo and views of the changing nature of intermodality. This has required some degree of repetition and cross-referencing when, for example, similar functions are presented in connection with different modes. The purpose is to try to make this volume useful as a reference, as well as an overview.
