NOTES: Federal transportation expenditures consist of outlays of the federal government including not only direct spending but also grants made to state and local governments. To avoid double counting, state and local transportation expenditures include their outlays from all sources of funds except federal grants received. Pipeline data only include federal-level expenditures, as state and local data are not available. State and local data are reported together, because disaggregated federal grants data are not available.
To eliminate the effects of inflation over time, the Bureau of Transportation Statistics converted current dollars (see table 10-3b in appendix B) to chained 2000 dollars.
