摘要：	Freight statistics should provide an objective baseline for transportation policy decisions, and national economic benefits of maritime transport necessitate improving inland waterways infrastructure. Proposed work included consolidating and learning from Lock Use, Performance, and Characteristic data collected by the US Army Corps of Engineers (USACE) and published by the Navigation Data Center. The objective is to estimate statistical models of annual tons locked by commodity group and lock, as a function of lock usage and unavailability (1993-2013), to discover knowledge of relationships between system disruption and economic consequences (commodity flow). In 2010 cargo transported on the inland waterway system included more than half of all crude petroleum, and more than one third of all coal and other fuel oils, affecting efficiency of economic sectors that rely on energy. Inland waterways traffic is expected to increase 11% by 2020, from 2012.
