The people mover-a short, high-capacity rail line serving only the high-density portions of a city--is a relatively new concept in transportation. The U.S. Department of Transportation recently decided to fund for such systems to test the effectiveness of the concept. They are expected to accomplish a number of desirable goals, including the reduction of pollution, congestion, and energy consumption and the revitalization of downtown areas. This paper concentrates on energy goals and examines the energy impact of six such systems. Research found that five of these systems will use more operating energy than the combination of modes that they replace, and the sixth will break even. Thus, even without taking into account the energy capital required to construct the systems, they have a net negative impact on energy consumption. The calculations used in this research are based on the patronage and mode split estimates of the transportation planners in the respective cities. This negative energy impact does not imply that the systems should not be built. Rather, they would be well justified, despite their energy losses, if they can make a significant impact on the reduction of smog and congestion or on downtown revitalization at a reasonable cost. /Author/
