The traffic control realizes optimum route control in case of train diagram disruptions, by automatic route setting and real-time diagram modification. The basic functions are route tracking, traffic control, and priority decision functions.

1. Automatic Route-Setting Control

Automatically controls route setting (signals, switches, etc.) at stations based on the train diagram.

2. Real-time Train Diagram Alterations Using Path Manipulation

Train Diagrams can be altered in real-time by manipulating diagram paths in the event of a disruption, such as that due to an accident. The Operation Management System continues to control route setting based on the new altered diagram.

3. Optimized Traffic Planning and Route Setting

The diagram can be altered in real-time to ensure route setting based on the optimum traffic plan (the altered train diagram) at that point, even when schedule disruptions arise.
