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. 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. Data include all modes except pipeline.
To eliminate the effects of inflation over time, the Bureau of Transportation Statistics converted current dollars (see table 10-6b in appendix B) to chained 2000 dollars.
