6.7 Signal Controllers
In VISSIM, signalized intersections can be modeled by means of the built-in
fixed-time control including the VISSIG add-on, if applicable, cf. section
6.7.3.10.
Additionally, various external signal control logic add-ons are available:
► Econolite ASC/3, cf. section 6.7.3.8.
► LISA+OMTC, cf. section 6.7.3.6.
► SCATS, cf. section 6.7.3.4.
► SCOOT, cf. section 6.7.3.5.
► VAP, cf. section 6.7.3.3.
► Ring Barrier Controller (RBC), cf. section 6.7.3.7.
The Ring Barrier Controller (RBC) is the default actuated signal controller
for licenses distributed by subsidiary PTV America.
The RBC User Manual can be accessed through the HELP menu in the
RBC GUI, additionally it is stored in the DOC folder of your VISSIM
installation.
Further custom external signal controller types support Siemens VA,
TRENDS, VAS, and VS-PLUS.
Users of the 32 bit edition of VISSIM receive the 32 bit version of the
specific *.DLL files. Accordingly, the 64 bit version of the specific *.DLL files
is provided to users of the 64 bit edition of VISSIM.
► Alternatively, you can also define an External controller using userdefined
signal controller *.DLL and signal controller *GUI.DLL files (in C
or C++ programming language), cf.section 6.7.3.9.
Users of the External add-on need to compile the SC DLL files in
accordance with the used VISSIM edition (32 bit or 64 bit).
Click menu HELP - LICENSE to verify which signal controllers are provided with
your license.
VISSIM provides access to external controller data only if the network has
been saved to file. This guarantees, that the controller files and the *.INP
file are stored in the same folder.
6.7.1 Signal Groups and Signal Heads
In VISSIM every signal controller (SC) is represented by its individual SC
number and signal groups (also referred to as signal phase) as its smallest
control unit. Depending on the selected control logic, VISSIM can simulate
up to 125 signal groups per signal controller. VISSIM also discriminates
between signal groups and signal heads.
