EVALUATION OF BART, AUGUST 3 TEST FOR TRANSBAY SERVICE

A full-scale performance test is reported of the Computer Augmented Backup System (CABS) for the Bay Area Rapid Transit (BART). The test, involving 36 trains, was performed to analyze the original computer augmented train control system as it would operate in a failure situation. Recommendations for improved automatic safeguards were made to achieve two objectives: (1) to improve the CABS ability to automatically maintain a one-station separation between trains; and (2) to have the protection revert to that provided by the basic Automatic Train Control system for the worst case that could arise in the computer augmented system.
