KEY: GDP = Gross Domestic Product.
NOTES: Total transportation-related final demand is the sum of all consumer, private business, and government purchases of transportation-related goods and services, plus net exports (i.e., the difference between transportation imports and transportation exports). Gross private domestic investment covers transportation equipment and structures for railroads and petroleum pipelines. To eliminate the effects of inflation over time, the Bureau of Transportation Statistics converted current dollars (see table 9-2b in appendix B) to chained 2000 dollars.
