BART TRAIN CONTROL SUBSYSTEMS: CABS AND SOR FOR THE TRANSBAY CROSSING

Preliminary progress is reported on two control subsystems of the Bay Area Rapid Transit (BART): (1) the Computer Augmented Backup System (CABS); and (2) the Sequential Occupancy Release System (SOR). CABS is an interim system for train separation to be used until the SOR Backup System is activated. CABS was analyzed, failure modes of both software and hardware were studied, and preliminary suggestions of corrective measures are made.
