SURVEY AND ANALYSIS OF ENERGY INTENSITY ESTIMATES FOR URBAN TRANSPORTATION MODES

Current interest in energy conservation has resulted in a spate of divergent estimates of the energy intensiveness of urban transit modes. This paper critically reviews the methodologies and data sources employed by these estimates. It is shown that a very small repertory of sources and methodologies underlie the energy intensity estimates and that variance among them is primarily attributable to contradictory load-factor assumptions. Energy intensity estimates for bus and rail transit are developed, and the inadequacies of automobile data are discussed. Bus transit is shown to be more efficient than rail transit, and it is shown that the energy advantage of light rail over heavy rail lies in construction, not operation. /Author/
