NOTES: Investment data here are in terms of calendar years unlike the other data in section 10, which are in terms of fiscal years. Investment in transportation infrastructure constitutes the purchase or construction value of transportation facilities and structures. Federal, state, and local data are combined. Data include all modes except pipeline; state and local rail data were only available from 1993-2000 when this report was prepared. Investment in rolling stock data consist of government outlays for motor vehicles only, because data for other rolling stock (e.g., aircraft, vessels, and boats) are not available.

These transportation investment data are not comparable to those in the September 2004 edition of this report because of changes in methodology and data sources. Data may not add to total because of independent rounding.To eliminate the effects of inflation over time, the Bureau of Transportation Statistics converted current dollars (see table 10-7b) to chained 2000 dollars.
