Abstract

The operator's interface to train traffic control systems must support high efficiency and a good work environment. Modern research on human-computer interaction in complex and dynamic work situations gives a framework for requirement specifications. Important aspects concern cognitive workload, limitations in memory capacity, dynamic decision processes and work environment problems. Operators should be able to prevent disturbances rather then to react on alarms. The train dispatchers' work has been studied through observations and interviews. Based on this, we have identified requirements for interfaces to tomorrow's traffic control systems. Prototypes of new operator interfaces have been imple
