"NOTES:  Average length of haul for freight is calculated by dividing ton-miles in the previous table by estimates of tonnage from the various data sources.  The calculation of average length of haul for passenger trips varies by mode:  for air carrier it is calculated by dividing revenue passenger-miles by revenue passenger enplanements; for commuter rail, intercity bus, and Amtrak it is calculated by dividing passenger-miles by number of passengers.
