Regional commodity flows vary tremendously due to the variation of the distribution of resources and freight infrastructure. These regional applications provide many maps displaying freight totals augmented with the LQ formulation (LQ of freight flows) and analyzes conducted at these regional level. These regions are developed through identification of major freight transit corridors (corridors tend to parallel an existing major rail freight line or major freight designated highway). These applications visualize the 2012 US Commodity Flows Survey freight totals in value and tonnage sent by region, by mode, and by NAICS 2-digit code (concurrent with STCG coding manual); and summed at these particular regional levels. These interactive applications allow the users to maneuver between different regions (by picking an area of interest), pick various attributes to display (by using the layers button layersbuttonlocated at the top-right of the application), and adjust to different levels of data corresponding to the view extent (by zoom-in or zoom-out in the application).
