NOTES,,,,,,,,,,,,,,,,,,,,,,,,,,
"BTS is developing more comprehensive and reliable estimates of tonne-kilometers for the air, truck, rail, water, and pipeline modes than are presented in table 1-46a.  These improved estimates are not comparable to data in table 1-46a.  Improved estimates for 1960-1989, which will allow more comprehensive and reliable data for the entire period from 1960 to present, are still under development and will be reported when they are completed.
