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.
