NOTES: Total transportation-related final demand is the sum of all consumer, private business, and government purchases of transportation-related goods and services, and net exports (i.e., transportation imports subtracted from transportation exports). Gross private domestic investment constitutes railroad and petroleum pipelines only.
All dollar amounts are expressed in chained 1996 dollars, unless otherwise specified. Current dollar amounts (which are available in appendix B of this report) were adjusted to eliminate the effects of inflation over time.
