6 The Traffic Network
6.7.1.2 Properties & Options
● No.: Unique identifier of the
signal head
● Name: Optional label or
comment
● SC: Selected signal
controller.
● Signal group: Selected
signal group.
● Type: Defines the display of
the signal head in the 2D
animation during a simulation
or test run. Options:
- Circular
- Left Arrow
- Right Arrow
- Invisible.
If the normal signal group of an (arrow) signal head has red or off and if
an "or signal group" is defined, the state of the or signal group is displayed
instead, without arrow (even if the normal signal group has amber
and the or signal group has red/amber or vice versa).
● Or Sig. Gr.: if this option is active, overlaps can be modeled by
defining a primary signal group as well as a secondary signal group and
combining them. The signal head will then turn green if either the first or
the second signal group is green. If the first signal group shows red, the
signal head displays the signal of the Or Sig. Gr. (even if it is amber or
red/amber). If one of the two signal groups shows amber and the other
one red/amber, the signal head displays green.
To display the signal status of each signal group separately, create a
short dummy link next to the intersection with a signal head for each
signal group.
● Label: When showing labels of all signal heads (see VIEW - NETWORK
ELEMENTS...) this option allows to individually switch off the label of that
one (cf. section 4.2.1).
● Vehicle Classes: Selected vehicle class(es) the signal head refers to.
Thus e.g. bus signals can be defined which are to be ignored by private
traffic.
● NEW 3D SIGNAL: Create a 3D signal, cf. section 4.1.4.2 and section
4.3.4.1.
To model right-turn movements (right-turn-on-red), which are controlled by
an own signal group before/after the actual stage and signalized by the
Circular type in the actual stage in VISSIM, enter the signal group of the
green arrow for the Or Sig.gr. option.
