Abstract

 

This paper begins with a concise national overview of the transported goods, classified by Standard Classification of Transport Goods, and their movements on the highway networks in the United States using TransCAD, a geographical information system with strong transportation planning capabilities and the freight analysis framework database version 2.2 orFAF2.2. Then, the paper constructs more national views of from, to, within, and through freight flows for the 50 U.S. states and DC to highlight the spatial patterns of total freight flows by state. The local views of total freight flows focus on Oklahoma, the so called “cross-road” state of America. A linear regression model is established by linking state freight flows to state major socio-economic indicators, such as employment, revenue, income, and payroll for the year 2002. State total freight flows in tonnage or by commodity are calculated to reveal top or bottom states in handling from, to, within, and through freight flows.
