"NOTES:  Average length of haul for freight is calculated by dividing tonne-kilometers 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-kilometers by revenue passenger enplanements; for commuter rail, intercity bus, and Amtrak it is calculated by dividing passenger-kilometers by number of passengers. ",,,,,,,,,,,,,,,,,
Numbers may differ slightly from previous year's metric tables because a higher precision conversion factor was used.,,,,,,,,,,,,,,,,,
