A study was undertaken to determine the causes of the divergences among published energy-intensity values and to prepare a set of consistent values. This volume presents the findings in relation to the freight transportation modes. After a brief overview of the important factors to be considered and the potential pitfalls facing users and analysts of energy intensity values, each of the major means of freight transportation -- air, marine, pipelines, rail, and truck -- is discussed. In each of the chapters, after a critique of the available data sources, a consistent time series of operational data and energy intensity values if presented for the major sectors of each mode. In addition, the energy-use effects of the major operational and hardware parameters are quantified so that the given energy intensity values may be modified to reflect a variety of possible changes in the transportation systems. Finally, matrices giving the great-circle distances and modal circuity ratios among the 50 largest standard metropolitan statistical areas are included to facilitate intermodal comparisons.
