OPERATIONS ANALYSIS OF GRAVITY-ASSISTED RAPID TRANSIT. IEEE TECHNICAL PAPERS PRESENTED AT THE JOINT ASME/IEEE/AAR RAILROAD CONFERENCE (ASSOCIATION OF AMERICAN RAILROADS) HELD APRIL 16-18, 1985, NEW YORK, NEW YORK
The author compares 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 sec. One month of incident reports of a modern operating transit system are reviewed to determine the failures to be simulated. The impact of failures resulting in station delays (30 to 360 sec), speed limit reduction (20 mph and 30 mph to one or more trains), vehicle performance (75 percent acceleration), are compared at scheduled headway of 90 to 180 sec.
