VISSIM 5.30-05 User Manual

Signal Controllers
● Pseudo stage: The duration of a stage which has been marked as
pseudo stage is always 0 seconds in any stage-based signal program, cf.
section 6.7.4.5.
Only for stages without any allocated interstage the pseudo stage option
can be checked.
Nevertheless, this option can be unchecked at any time.
● Stage diagram: Graphical stage display.
For display of direction indicating arrows, nodes are required in VISSIM.
One for the analyzed node and one for each neighbouring node. These
nodes have to be selected for Node evalulation.
6.7.4.4 Editing Stage Assignments (VISSIG add-on)
Via Stage assignments in the navigator, you can either permit or block each
of the signal groups or mark their status as not relevant.
In the Intergreen matrices table, the selected matrix is marked as Default.
This matrix has to be selected in the Intergreens selection list via Stage
assignments in the navigator.
Double-click in a cell or click an arrow in the graphical display to change the
state of the stage’s signal group. The cycle includes the following states:
Signal group is permitted in this stage
Signal group is blocked in this stage
The state of the signal group is not relevant in this stage (in case of
partial junction control, for example)
After selection of a default intergreen matrix, the generated stages are
checked for conflicting flows. Permitted conflicting signal groups within a
stage are highlighted red in this table.
