Editing signal groups

You can change the signal state sequence and its minimum durations. For signal states that in the signal sequence possess a variable duration, the value entered is interpreted as the minimum duration. For any other signal states, the value entered is interpreted as the duration. This, for instance, allows you to supply 2 seconds red-amber, 5 seconds amber for 70 km/h (speed limit in Germany) or 15 seconds minimum green for a heavily loaded straight flow.

1.  Open the signal controller editor (Opening and using the signal controller editor).

2.  In the Navigator, click Signal groups.

The signal groups list opens.

3.  Right-click the entry of your choice.

4.  On the shortcut menu, click Edit.

In the window, the name, default signal sequence, signal duration, and a description are displayed.

Tip: Alternatively, you can show the window via the following functions: ►  In the Navigator, click the signal group. ►  In the signal groups list, in the signal group row of your choice, double-click the Notes field.

5.  Make the desired changes:

Element	Description
Name	Name of signal group, may contain Unicode characters.
Default sequence	With the exception of permanent signal sequences, you can choose any of the signal state sequences defined (Performing green time optimization of stage-based fixed time controllers): red > red/amber > green > amber red > green red > red/amber > green > flashing green > amber red > green > flashing green red > green > amber
Note: If in the signal controller editor, on the Edit menu, you click > Options > Optimizations and then click Add minimum times in interstage, the increase in the minimum green time or transition time might mean that individual interstages have to be recalculated. This is why before changes are accepted, Vissim checks whether the interstages need to be recalculated due to these changes. If required, a message is then displayed, asking whether you still want the changes to be carried out. Within this context, changes made in the meantime to optimization settings or stages might also require recalculations, which are not due to the actual change.
(Minimum) durations	Symbol for signal state sequence and minimum durations in seconds of the signal state
Notes	optional entry of text
