This paper compares in detail gravity assisted rapid transit (GART) with 6 percent grades before and after each station and conventional systems in terms of energy consumption, run time, line capacity and schedule stability under abnormal circumstances. The study draws on procedures and computer programs that have been applied to engineering designs and studies of actual transit systems. Parametric analyses of run times and energy consumption include the impact of alternate accelerating and braking levels. A capacity analysis is performed, using a network simulation computer program to determine the location and severity of signal delays. Based on results of initial simulations, the signal block design was revised to eliminate bottlenecks in normal operations. The systems are then compared at headways of 80 to 180 seconds. Results show that GART reduces energy consumption by 8-15 percent and that accelerating and coasting policies can provide similar savings to either system.
