6 The Traffic Network
To the new signal groups, the signal state sequence Red-Red / Amber-
Green-Amber is assigned. To ease data input the following is
recommended: Create a signal group for each of the required signal group
types, supply their standard signal sequence and duplicate this template
finally as often as necessary.
Furthermore, you may edit the list as follows:
● No.: Double-click in the column and edit the number of the signal group.
● Name: Double-click in the column and edit the name of the signal group.
● Notes: Double-click in the column to call the editing view. You may enter
a comment describing the signal group.
The editing view
Here you may change the parameters of the particular signal group as
follows:
● Name: Short “speaking” name of the signal group.
● Default sequence: Except for permanent signal sequences, any signal
state sequence mentioned in section ● can be selected:
- Red – Red / Amber – Green - Amber
- Red - Green
- Red – Red / Amber – Green - Flashing Green - Amber
- Red – Green - Flashing Green
- Red – Green - Amber
If option Add minimum times in interstage has been checked via menu
VIEW - Options - [OPTIMIZATIONS], increasing the duration of either the
minimum green or increasing the duration of a fixed state may force the
recalculation of particular interstages. Prior to storing the new data it is
checked which of the interstages have to be recalculated. The appropriate
query appears, if applicable.
Also changes to current optimization settings or to stages may lead to
recalculations which are not caused by the changes themselves.
● Default durations: Graphical display of the signal state sequence. The
particular value of the signal state is shown. Double-click for value
modification.
● Notes: Enter a comment describing the intended usage of the signal
group.
