TRANSPORTATION ENERGY DATA BOOK: EDITION 22—2002
Great care should be taken when comparing modal energy intensity data among modes. Because of the inherent differences between the
transportation modes in the nature of services, routes available, and many additional factors, it is not possible to obtain truly comparable
national energy intensities among modes. These values are averages, and there is a great deal of variability even within a mode.
a Data are not available.
b 2000 energy use data. 2001 data are not available.
c Includes domestic scheduled services and ½ of international scheduled services (Table 2.13 shows only domestic services). These energy intensities may be inflated because all
energy use is attributed to passengers – cargo energy use is not taken into account.
d Amtrak only.
e Light and heavy rail.
