THE BART CHRONICLE: DRY RUNS BY COMPUTER

The advent of control and computing hardware that permits reliable and economic simulation of discrete systems has made possible simulation of rapid transit systems. Simulation is used to: test the control logic on the main computer, train personnel in the operation of the system, and allow for further development and testing of operating decisions. The control system will be used to: (1) adjust station dwell time for trains, (2) revise dispatching schedules, (3) distribute the intervals between trains, and (4) control the sequence of trains over a single track when the other track is out of service. Control logic includes train strategies and, for abnormal situations, decision tables. The program comprises four parts: (1) setting up the model, (2) initializing the model, (3) sequence of events, and (4) computerized control logic. The simulator for the standby computer can be used to: (1) test centralized supervisory monitoring, (2) simplify the problem of evaluating changes, (3) determine the effects of changes that might otherwise never be tried, and (4) train the train console operator.
