Excerpt from Conserving Energy and Preserving the Environment Bureau of Transportation Statistics: US D. O.T.
6 In each case, we use the most recent and comprehensive data available. The energy section draws on 1998 data on travel by
private and public transportation, because 1998 is the latest year for which data on energy consumption by private vehicles is
available (1999 data on energy use by public transportation systems is available). The analysis of public transportation and the
environment draws on 1999 data, because that is the most recent data available on pollution emissions by public and private
vehicles.
