17 Approach The search for efficient, low-emission methods of transporting marine containers inland has led developers to examine a wide range of technologies and systems configurations. As of early 2014, most advanced-technology proposals are conceptual, without working examples in existence.

18 Evaluating Alternatives for Landside Transport of Ocean Containers Container Transport Technologies The research team identified a continuum of technologies beginning with very simple incremental improvements in the current drayage system and continuing to very new and somewhat unorthodox approaches. The technologies identified by the research team are described in Table 2-1.
