Table 1-35M: Average Length of Haul, Domestic Freight and Passenger Modes(Kilometers)
KEY: N = data do not exist; U = data are not available. a Total Class I and Class II motor carriers of freight (less-than-truckload, specialized carrier for truckload, and others). b Amtrak began operations in 1971. Data are reported for fiscal years. NOTES Average length of haul for freight is calculated by dividing ton-miles in table 1-46 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. These numbers were then converted to kilometers. 1.609344 kilometers = 1 mile.
