Abstract
The forthcoming shortages in transit fuels and electricity resources were the basis for forecasts that fuel prices will quadruple by 1980, while transit electricity will have doubled in cost. One effect of these energy price escalations on urban transit planning is to shift downward the economic balance between buses-on-busways and trains-on-rails. A program is proposed to achieve better balanced, all-electric bus/rail urban transit systems that minimize capital and energy consumption.
