Abstract:

The paper concerns the energy requirements of the Bay Area Rapid Transit system in five areas: traction energy, station energy, maintenance energy, construction energy, and impact energy. Vehicle traction energy is bounded by a probable lower bound of 3.2 kW-h/car-mile (7.2 MJ/km) and a probable upper bound of 5.5 kW-h/car-mile (12.4 MJ/km). When the station and maintenance energies are added, it is expected that the eventual total operating energy cost will lie between 6 and 7 kW-h/car-mile (13.5 and 15.7 MJ/km). The construction energy is calculated through the use of energy input-output analyses and is approximately equal to the total operation energy over a 50-year projected system life. The impact energy of Bay Area Rapid Transit, that is, the energy associated with other systems built because of the existence of Bay Area Rapid Transit, is discussed. There are not as yet sufficient data available to make an estimate of this energy. The important problem of energy dependence on loading is studied, and it is found that there is a nearly inverse (hyperbolic) relation between energy intensity (kW-h/passenger-mile (joule/kilometer)) and the vehicle loading factor.
