Signal Controllers
● Offset: A value that delays the first (and therefore all subsequent) cycle
by seconds.
For Fixed time control, significant changes have been performed and the
functionality has been extended by various new features, One of them is
the VISSIG add-on, for example. Please refer to section 6.7.3.10 for the
comprehensive description.
For the selected control strategy, the tabs contain special data, e.g. input file
names etc. (see below).
Here, the settings for the Signal timing plan display window (during
simulation run) can be edited, cf. section 11.8.
For SC using an external control strategy, the SC/Detector Record settings
can be edited, cf. section 11.9.
6.7.3.3 VAP - Vehicle-Actuated Signal Control (optional module)
VISSIM can model actuated signal control in conjunction with an external
signal state generator if the optional VAP module is installed. This signal
state generator allows users to define their own signal control logic including
any type of special features (e.g. PT priority, railroad preemption, emergency
vehicle preemption, variable message signs on motorways etc.). The use of
the external signal state generator and its VAP programming language is
explained in file VAP.PDF in the DOCUMENTS folder of your VISSIM
installation. VisVAP (the optional graphical desktop to model flow chart
logics) is explained in file VISVAP.PDF in the DOCUMENTS folder of your
VISSIM installation.
Users of the 32 bit edition of VISSIM receive the 32 bit version of the VAP
DLL files. Accordingly, the 64 bit version of the VAP DLLs is provided for
users of the 64 bit edition of VISSIM.
For VAP signal controllers using an Offset, values within VAP need to be
adapted by this offset, too, in order to prevent malfunction of the time
conditions.
6.7.3.4 SCATS (optional module)
SCATS requires
► the files SCATS.DLL and SCATS_GUI.DLL and
► the progams WinTraff and ScatSim (and SimHub if applicable).
These are provided by the Roads and Traffic Authority of New South Wales,
Australia.
