Billions of chained 2000 dollars
NOTES: Investment in transportation infrastructure constitutes the purchase or construction value of transportation facilities and structures. Data include all modes except pipeline. In addition, federal government data on rail infrastructure investments are not available, and state and local rail infrastructure investment data are only available from 1993-2000. Investment in rolling stock data consist of government outlays for motor vehicles only, because data for other rolling stock (e.g., aircrafts, vessels, and boats) are not available.
Current dollar amounts (see table 14-5b) were converted to chained 2000 dollars by the Bureau of Transportation Statistics to eliminate the effects of inflation over time.
