- Detect HRI closure,
- Detect vehicle/train collisions.
There are two processes in this DFD:
a) Close HRI on Detection (1.6.1.6.1)
b) Detect Imminent Vehicle/Train Collision (1.6.1.6.2)
All data is received by process (a) and also sent to other facilities within the Manage Traffic function. Process (b) reports any vehicle/train collisions and reports the collision to process (a).
