Signal Controllers
In the editing view of a signal group the signal state sequence can be edited
and also the Default durations of this signal state sequence. For signal states
with a variable duration in the signal state sequence, the entered value is
regarded as minimum duration. Otherwise it is regarded as duration.
In this way you can supply for instance 2 seconds Red-Amber, 5 seconds
Amber for 70 km/h permitted speed (in Germany) or 15 seconds Minimum
Green for a heavily loaded straight flow. The editing view can be accessed
from the navigator, via the context menu or by double-click in one of the noneditable
columns of the particular row in the list.
6.7.4.2 Editing Intergreen Matrices
Intergreen is the time that is required to elapse between the Green End of a
clearing flow and the Green Start of an entering flow. Keeping the intergreen
guarantees that the clearing flow will not come into conflict with the entering
flow.
Conflicting flows and intergreens cannot be calculated. During intergreen
data input no checks are performed, especially the symmetry of intergreen
matrices is not checked.
