Forced cancellation is required if no correct logout is performed. To prevent the controller from "hanging" in these cases, vs | plus provides various options for forced cancellation:
- Forced cancellation with repetition of green windows:
The PT request of a train or bus remains until the traffic stream waiting time is equal to the self-counting time. - Forced cancellation without repetition of green windows:
Forced cancellation occurs after the first green window that appears during or after the expected arrival second. - Forced cancellation without green.
