Preamble
This document provides an overview of the most important changes in PTV Vissim 6
compared to Vissim 5.40 in handling and behavior.
A detailed description of the functionality can be found in the Vissim 6 online help.
1 Right Click Behavior
When you start Vissim 6 for the first time on your computer, you will see this dialog:
Now, you must decide what a click with the right mouse button will do in the network editor:
If you select the first option (“context menu”), a right click in a network editor will open a
context menu. In order to insert a network object directly, you need to press the Ctrl key
when right-clicking / right-dragging.
If you select the second option (“create new object”), a right-click / right-drag in a network
editor will insert a network object (as in Vissim 5.40). If you want to open a context menu in
a network editor, you need to press the Ctrl key when right-clicking.
In all other windows, a right-click opens always the context menu, independent of this
setting in the user preferences (which can be changed later through the “Edit” menu).

2 Files
Network File
The Vissim 6 network file has the extension *.inpx and uses the XML format. Old *.inp files
can be read in if they have been saved with Vissim 5.40. (Older *.inp files need to be
opened in and saved again with Vissim 5.40.)
All settings for evaluation files, including the active/passive flag, are saved in the *.inpx file.
There are no more separate configuration or filter files.
Data files for external signal controllers (including *.sig files of fixed time controllers), path
and cost files for dynamic assignment, and background images, texture and 3D model files
are still separate files, referenced by file name and path in the *.inpx file.
Layout File
The new layout file contains the graphical settings of all Vissim windows and sidebars,
including the network editors’ graphic parameters and the list layouts.
The layout file has the extension *.layx and uses the XML format. Old *.ini files are ignored.
When an *.inpx file is saved, a *.layx file with the same name prefix is automatically saved
in the same directory. This *.layx file is read in automatically, too, when the *.inpx file is
opened, so the layout of the whole user interface (window positions, graphic parameters)
looks exactly as when the *.inpx file was saved.
Automatic saving of the *.layx file can be switched off in the user preferences (menu “Edit”).
In the same menu, an additional option can be switched on to save the *.layx file when the
current network is discarded, i.e. when Vissim is closed or when a (new) *.inpx file is
opened or when File/New is selected. (This makes sure the layout of the previous network
looks the same when it is reopened as when it was closed.)
Evaluation Files
Many evaluation text files and database tables are written by Vissim 6 in the same format
as in Vissim 5.40. The result data of most aggregated evaluations is collected in result
attributes of network objects now, which are saved in an internal subdirectory (*.results\ in
the data directory, with one database file per simulation run). Usually, direct user access to
this directory should not be necessary, as all data is available in the GUI of Vissim 6 and
can be exported from there.

3 User Interface / Workspace
3.1 Sidebars
There are several new sidebars which replace toolbars and dialogs from Vissim 5.40 and
add new functionality: Network Objects, Levels, Backgrounds, Smart Map, Quick View.
Closed sidebars can be opened from the “View” menu.
3.2 Window Handling
Any number of network (editor) windows (for display of different views in the network) and
list windows can be opened from the “View” menu. (There is still no more than one network
loaded at a time!)
All windows can be made floating by dragging them out of the main window. Windows can
be docked and tabbed with each other, using the docking manager which appears when a
window is dragged. Sidebars can be docked and tabbed with each other, too, but not
tabbed with windows.
What is new in PTV Vissim 6 © PTV AG 6
3.3 Undo / Redo
The undo function allows users to undo the last changes on any network objects (in a
network editor window, a list window or the quick view sidebar). The redo function allows
users to undo the last undo operations. The size of the undo history, i.e. the maximum
number of operations which can be undone, can be set in the user preferences. Layout
changes are not undoable.
3.4 Dialogs
There are no dialogs anymore for editing multiple objects at the same time or for selecting
objects from a list on the left side. Instead, there are list windows (see below) for all
network objects and, for most object types, single edit dialogs. The edit dialog for an object
can be opened from the network window by double-clicking the object, or by (Ctrl-)right-
clicking and selecting “Edit…” in the context menu, and from the list window by right-
clicking and selecting “Edit…”.
Time intervals for network objects (e.g. inputs, routing decisions) can only be edited in the
list window “Time Intervals”, where the relevant object type can be selected from a drop-
down list box in the toolbar.
3.5 Network Object Sidebar
In contrast to Vissim 5.40, it’s now possible to select objects of different types (even as
multiselection) in the network editor without changing the mode in the toolbar in between.
What is new in PTV Vissim 6 © PTV AG 7
There is no special multiselection mode or label mode anymore. The display of objects of
one type can be switched on and off with one mouse click, as well as the display of labels.
In the sidebar, there are 5 controls for each network object type: visibility (icon),
selectability (lock), insert mode (name), label (“A”) und graphic parameters/preview.
If you don’t need the columns for selectability, label and/or graphic parameters you can
remove these from the sidebar through the context menu of the sidebar. In addition, you
can decide to display only the rows for network objects for vehicle or pedestrian traffic.
A click on the visibility icon switches on/off the display of the objects of this type in the
network window. Activating the selectability lock for a visible type prevents that objects of
that type can be (inadvertently) selected and changed/moved in the network window.
(Invisible objects can never be selected.) The label control (“A”) is used to switch/on off the
labels for the objects of this type in the network window.
If multiple network windows are open, all these settings affect only the last network window
which had focus.
Objects of the type selected for insert mode (through click on the name of the type,
highlighting the complete row) are always visible and selectable in all network windows
(unless their level is hidden or locked).
For routes, areas and obstacles, the subtype (static/partial/… respectively polygon/
rectangle) to be inserted is shown in parentheses and can be selected in a drop-down box
which opens after a click on the drop-down button (or a second click on the object type
name).
A click on the graphic parameters control (preview) opens a table containing all available
graphic parameters for this object type, including label attribute, label color and font size
and coloring options for the objects themselves. For links, pedestrian areas/ramps,
vehicles, and pedestrians, user-defined color schemes can be selected to display a color-
What is new in PTV Vissim 6 © PTV AG 8
coded classification by any numeric attribute. The graphic parameters affect only the last
network window which had focus.
After a click in a different network window, the network object sidebar displays the settings
for that network window.
3.6 Network Editor Window
The toolbar of the network window has controls to access the basic graphic parameters
and the 3D graphic parameters, controls to switch between wire-frame and normal display
and between 2D and 3D, controls to select the behavior for synchronization with list and
other network windows (Auto Pan/Auto Zoom, see below) and for navigation in the network
(zoom in and out, back/forward to previous/next zoom view, pan mode, in 3D rotate mode
and flight mode, camera position and mouse sensitivity).
The current layout of a network window (i.e. all graphic parameters and the network object
sidebar settings but not the zoom view) can be saved with a user-defined name by entering
What is new in PTV Vissim 6 © PTV AG 9
that name in the drop-down listbox “Select layout…” and pressing Enter. A previously
saved named layout can be loaded (in any network window) by selecting its name from that
drop-down listbox.
The special display modes “quick mode” (Ctrl-Q, maximum simulation speed by switching
off the display of all changing objects, i.e. vehicles and pedestrians and dynamic labels and
color schemes) and “simple network display” (Ctrl-N, display only link and area-type objects
but no objects on links and areas) affect all network windows and thus are accessible by
controls in the main toolbar.
In the network window, network objects are highlighted as soon as the mouse pointer
hovers over them, to show which object will be selected with a mouse click at that position.
In all network windows and all synchronized lists, the same objects are selected. (Even if
objects are not visible in a network window because visibility of the object type is off.)
New network objects can be added only if the insert mode is active for the respective type.
Sub-objects (spline points of links, intermediate points of routes and lines, node or area
polygon vertices) can be added and edited only if the insert mode is active for the
respective main object type.
As already described above, there are two options for the behavior upon right-click in the
network editor which can be selected in the user preferences:
A) New mode:
Right-click opens a context menu; Ctrl-right-click inserts an object directly.
B) Classic mode (as in Vissim 5):
Right-click inserts an object directly; Ctrl-right-click opens a context menu.
In any case, the context menu includes an item to insert an object of the current type (insert
mode), as well as all operations available for the selected object(s) and the current type.
Note that inserting objects that have a spatial extent (e.g. links, reduced speed areas,
pedestrian areas) through the context menu behaves differently from inserting these
objects with right-drag / Ctrl-right-drag:
Objects are directly created with a predefined size, which can be adjusted afterwards.
Especially, it is not (yet) possible to insert connectors through the context menu. This
means that you must always use (Ctrl-) right-drag to insert a connector.
Another option in the user preferences defines what happens after adding a new network
object in a network editor window:
What is new in PTV Vissim 6 © PTV AG 10
A) The edit dialog with the data of the new object is opened if available; otherwise a list
window with all objects of this type is shown (brought to the top or opened) and the
row of the new object is selected.
B) The edit dialog with the data of the new object is opened if available; otherwise
nothing is shown automatically.
C) The list window is shown (even if there is an edit dialog for this type).
D) Nothing is shown automatically; the attributes of the new object keep their default
values.
3.7 Levels Sidebar
Levels are network objects now, so they can be added/deleted through the context menu in
their list window (not in the sidebar). In addition to the construction elements of the
pedestrian simulation (areas, ramps, obstacles), links, backgrounds, static 3D models and
3D signals have a level now as well.
In the levels sidebar, for each level, the display of static objects on that level can switched
on/off (visible/invisible), selection of objects on that level in the network editor can be
switched on/off, and the display of vehicles and pedestrians on that level can be switched
on/off independently. All these settings affect only the last network window which had
focus.
3.8 Backgrounds Sidebar
Background images are normal network objects now. They can be added by (Ctrl-)right-
clicking or -dragging in a network window if their insert mode is active (“Background
Images” selected in the network object sidebar). Background images can be moved, scaled
or deleted in any insert mode (provided neither their level nor the whole type is locked).
When you open an *.inp file written by Vissim 5.40, there are no background images in the
network (background images mentioned in *.ini files are not added automatically). All
background images must be inserted in the network editor. When a background image is
inserted, the associated scaling file (*.bgr or *.hgr) from Vissim 5.40 is read together with
the image file, so the position and size should be correct. For background objects already
defined in a Vissim 6 network, these scaling files are not used anymore.
The display of each background image can be switched on/off in the backgrounds sidebar.
These settings affect only the last network window which had focus.
What is new in PTV Vissim 6 © PTV AG 11
3.9 Smart Map Sidebar
This sidebar shows the location of the current network sections of all open network
windows with 2D view, one yellow rectangle for each such network window (the last active
network window is marked with a thicker line). A section can be moved by dragging it with
the mouse, replaced by a new section with Ctrl-left-drag, and a new network window can
be opened with Ctrl-right-drag. A right-click opens the context menu which includes the
option to apply the graphic parameters from the last network window which had focus to
the smart map network display.
3.10 Quick View Sidebar
This sidebar shows the values of a user-selected subset of all attributes of the network
object(s) in the current global selection (in the network windows and synchronized list
windows). The attributes to be displayed and the formatting can be selected by the user in
the attribute selection dialog which can be accessed through the wrench icon in the
sidebar.
What is new in PTV Vissim 6 © PTV AG 12
If multiple objects of different types are selected, no attributes are shown yet. For multiple
objects of the same type, an attribute value is shown as * (asterisk) if the values differ
between selected objects, otherwise the common value for all selected objects is shown.
Attribute values can be edited in the quick view sidebar, too. If multiple objects (all from the
same type) are selected, the new value is applied to all selected objects.
3.11 List Windows
List windows can be opened from the menu (under “Lists” for all network object types or
under “Base Data”, “Traffic”, “Signal Control”, “Evaluation” and “Presentation” for the
respective subsets) or from the context menu of the network object sidebar (right-click in
the desired row) or from the context menu in a network window (“Show in List”).
The content of a list can be sorted by any column (A..Z buttons in the toolbar), and the
complete list can be exported into a database or into a semicolon-separated text file (*.att).
Arbitrary selections can be copied and pasted to/from the clipboard, i.e. to/from other
applications like Excel.
A list window shows all network objects of one type, one row per object, with one column
per attribute. The attributes to be displayed and the formatting can be selected by the user
What is new in PTV Vissim 6 © PTV AG 13
in the attribute selection dialog, which can be accessed through the wrench icon in the list
window toolbar.
Result attributes in lists
Several network objects have result attributes. The values of these attributes are collected
during simulation runs. Result attributes can have up to three sub-attributes: Simulation run
number, time interval index and vehicle class or pedestrian class. For the sub-attribute
simulation run number, there are additional special values “current run”, “average of all
runs”, “standard deviation between runs”, “minimum of all runs”, “maximum of all runs”. For
the sub-attribute time interval, there are the special values “last completed interval”, “total
of all intervals”, “average of all intervals”, “standard deviation of all intervals”, “minimum of
all intervals” and “maximum of all intervals”.
In a normal list window, one column can display the value of one result attribute for one
specific combination of sub-attribute values, e.g. the average travel time in simulation run
number 4, time interval 300-600, for vehicle class “light trucks”. To display results in a
different scheme, there is an alternative concept called “Result Lists” (see below).
As the definition of a list layout with attributes with sub-attributes can be cumbersome
(because there can be many time intervals and many simulation runs), there is a filter
dialog available to support the user in selecting the desired sub-attributes. Here, the user
can select which simulation runs (or aggregates of simulation runs), which time intervals (or
aggregates of time intervals), and which vehicle/pedestrian classes are available for
selection to be displayed in the list.
What is new in PTV Vissim 6 © PTV AG 14
Synchronized Lists
Through the synchronization button in the toolbar, a list window can be synchronized with
the global selection. If the synchronization is active, any click in the list window changes the
global selection, i.e. a simple click deselects all previously selected objects and selects
only the new object, and Ctrl-click adds the new object to the global (multi-)selection. The
new global selection is visible in all network windows (as far as these objects are visible
there) and in all synchronized list windows. Depending on the state of the synchronization
toolbar buttons in the network window, the view is automatically panned (“Auto pan”) or
panned and zoomed (“Auto zoom”) to the new global selection.
Vice versa, any click in a network editor which changes the global selection changes the
selection in all synchronized list windows to the globally selected objects of that type and
scrolls in the list windows so that the first selected object is visible.
Coupled Lists
If an object type has relations to other object types (e.g. a routing decision to routes), one
of these relations can be displayed adjacent to the main list (selectable in a drop-down
listbox in the list window toolbar). In this coupled list, all objects are displayed which are
referenced from the selected objects in the main list, e.g. all routes which belong to one of
the routing decisions which are selected in the main list.
The attributes displayed in a coupled list can be selected by the user separately through
the attribute selection dialog (wrench icon). Synchronization with the global selection can
be activated for the coupled list, too (which deactivates the synchronization of the main list
automatically and vice versa).
Coupled lists are most useful for the access to child objects of main objects, e.g. lanes and
signal groups. In some cases, there are direct list windows for child objects available from
the menu “Lists”.
Result Lists
In a result list which can be opened from the “Lists” menu, there is automatically one row
per combination of network object and simulation run number and time interval, i.e. only the
vehicle/pedestrian class is shown as sub-attribute in the columns. Additional rows for
average, standard deviation, minimum and maximum of all simulation runs and/or all time
intervals can be switched on/off in the result list window toolbar (through the “Sigma” icon
buttons).
What is new in PTV Vissim 6 © PTV AG 15
List Export
In the list window toolbars there are buttons for export to a semicolon-separated text file
(*.att for “attribute file”) or to a database table. The complete content of the list window is
exported to the respective file, using the current layout (displayed decimals and units). In
addition, there is a button (disk with arrow) for “Autosave after simulation”. If this is
activated, the list is exported automatically at the end of each simulation run.
4 Simulation
Settings
Basic settings of the vehicle and pedestrian behavior are found under Base Data / Network
Settings now. Default units (metric/imperial) for the display of values can be selected there
as well.
What is new in PTV Vissim 6 © PTV AG 16
A multi-run simulation is started exactly like a single continuous simulation now, with the
respective settings for number of runs etc. in the simulation parameters.
The evaluations output directory is used for single simulations, too.
Inputs
Vehicle and Pedestrian Inputs which can not be completed in the assigned time interval are
now extended into the next time interval (if there is one). The remaining latent demand is
added to the demand of that next interval and uses the traffic composition of that interval.
Simulation speed in 2D
The problem of Vissim 5.40 with the Aero desktop themes on Windows 7 does not affect
Vissim 6. The 2D visualization is not slowed down by Aero desktop themes anymore.
In very small networks, especially with many standing vehicles, the 2D visualization in
Vissim 6 can be quite a bit slower than in Vissim 5.40. The same applies to bigger
networks if only a very small section is visible in a network window. In Vissim 6, the 2D
visualization of big networks and big sections is much faster but it doesn’t get faster if you
zoom in or if many vehicles are standing.
Simulation speed in 3D
The speed of the 3D visualization is still determined by the graphics card and the graphics
driver. If the 3D visualization is abnormally slow on a Nvidia GeForce card from the series
400 to 700, it is recommended to switch off the option “Double sided lighting” under User
Preferences / Graphics.
If Vissim 6 crashes during startup while the splash screen is still visible, this is usually
caused by a bug in the graphics driver, typically on notebooks with integrated processor
graphics (Intel HD) and no dedicated graphics card. Please update your graphics driver if
there is a more recent version available on the website of the manufacturer. If this doesn’t
help, you can start the program VDiagGUI.exe from the Exe folder of your Vissim
installation, click the button DISABLE 3D, close VDiagGUI, and start Vissim again. Usually,
this prevents the crash (but the 3D mode is disabled).
5 Evaluations
There are two types of evaluations: Direct output and result attributes.
Direct output evaluations
These are written directly into a text file or a database as in Vissim 5.40, either
continuously during the simulation run (raw data) or at the end of the simulation run
(several special evaluations). Direct output evaluations can be activated under Evaluation /
Configuration / Direct Output, and their parameters can be set there as well.
Result attributes
These are specific attributes of network objects which usually contain aggregated values.
The values can be shown anywhere where static attributes can be shown (list window,
quick view sidebar, label text in the network window, color from a color scheme) and
additionally in result list windows (see above).
What is new in PTV Vissim 6 © PTV AG 17
Collection of result attributes data for a network object type in subsequent simulation runs
can be activated under Evaluation / Configuration / Result Attributes. Parameters for these
evaluations can be set there as well. Result attribute values are determined only if “collect
data” for an evaluation is active before a simulation run.
If results are to be collected separately for specific vehicle classes and/or pedestrian
classes (in addition to the virtual classes “all vehicle types” and “all pedestrian types” which
are always collected), the desired classes need to be selected in the list boxes in this
configuration dialog.
Result attribute data from previous simulation runs is deleted if either the respective
simulation run is deleted from the simulation run list window or if the evaluation
configuration option “Overwrite all previous results” is active (in this case all old results are
deleted at the start of a simulation run). If “Keep results from previous simulation runs” is
selected instead, there is an additional option to add columns for results of the previous run
to list windows automatically at the start of each simulation run. Each column with sub-
attribute “current simulation run” gets the number of the previous run instead, and a new
column for “current run” is added for each of these columns.
Result data is deleted also if objects of the respective type are added, deleted or edited or
if the configuration of the evaluation is changed (e.g. the time interval length). If only other
objects are modified, e.g. signal control or demand data, result data from previous runs
(e.g. travel times) is still available. In this case, result data from different scenarios can be
collected in one network file (respectively the associated *.results directory) and checked
and visualized in Vissim, exactly as multiple runs with different random seeds.
6 Data Model
2D/3D Models
A 2D/3D model distribution contains references to one or more 2D/3D models, each one
with a relative share. Each 2D/3D model contains a list of 2D/3D model segments with
geometry data and (optional) model file references. (This allows the same combination of
model segments, e.g. the segments of an articulated tram, to be used in multiple model
distributions more easily.)
What is new in PTV Vissim 6 © PTV AG 18
AVI Recording
Each “camera position” (new object type) contains a certain 3D view. The current view in a
network window in 3D mode can be saved as a camera position by entering a new name in
the drop-down list “Select Camera Position…” in the network window toolbar. The view can
be set to an existing camera position by selecting that camera position’s name in the drop-
down list.
The new object type “storyboard” can contain multiple keyframes, each one referring to one
camera position. There can be multiple storyboards. When “AVI Recording” (in the
Presentation menu) is active during a simulation run, one AVI file is created for each
storyboard with the active flag “RecToAVI”.
Vehicle Occupancy
The occupancy of a vehicle type is defined as a reference to an occupancy distribution
(new type of distribution, can be an empirical or normal distribution) – not a simple double
value as in 5.40.
Each vehicle of a vehicle type gets an independent random value from this distribution,
rounded to the nearest integer. (Non-integer occupancy values defined in old *.inp files are
converted to distributions, keeping the same probabilities for upper and lower value.)
Vehicle Width
The vehicle width is not an input attribute of a vehicle type anymore, but (as the vehicle
length) an attribute of a 2D/3D vehicle model calculated as maximum width of its 2D/3D
model segments, so vehicles from the same vehicle type can have different widths. When
an old *.inp file is opened, each 2D/3D model is assigned the user-defined width of the first
vehicle type that uses this model. If this is not equal to the width of the 3D model of the
*.v3d model file, there is a message about the geometry not matching when the *.inp or
*.inpx file is loaded, with an option to use the widths of the *.v3d model files.
Pedestrian Behavior
The maximum acceleration function (per pedestrian type) has been removed. All behavior
parameters are now available inside the GUI. Global parameters can be accessed via Base
Data / Network Settings / Pedestrian Behavior. Parameters which can depend on the
pedestrian type and/or location are defined directly in the walking behavior objects. Each
pedestrian type references a walking behavior. An area behavior type can have any
number of elements, each one assigning a walking behavior (and a desired speed
distribution) to a pedestrian class for a specific time interval. Parameters which only affect
the movement from one pedestrian route location (start, end or intermediate point of a
pedestrian route) to the next one are defined directly as attributes of that second location
and can be edited in the pedestrian routes list window with coupled list pedestrian route
What is new in PTV Vissim 6 © PTV AG 19
locations or in the dialog, which can be opened with a double-click on a route location point
in the pedestrian routes insert mode.
7 COM Interface
All attributes of all objects can be accessed through COM with the method AttValue of the
respective object. Read access is always possible, write access only if the attribute is not
read-only and for many attributes not during a simulation run. The COM manual has been
replaced by an introduction document (“Vissim 6 – COM.pdf”) and an HTML reference
which is part of the Vissim 6 online help (last chapter). Because of the generic data model,
the syntax for access to some objects and attributes has changed compared to Vissim
5.40.

9 Known Bugs
The most important issues presently known are these:
Block signalization does not work properly yet. (Bug IDs 7750, 7776)
Signal times table: In the default configuration of the signal times table window, no
signal groups and detectors are shown. They need to be added to the window
layout explicitly. (Bug ID 7759)
Time interval list: The original list layout of a time interval list is not restored when
loading a *.layx file. (Bug ID 7237)
Workspace layout: When adding a new tab, the window height increases. When
removing a tab from a group, the window height decreases. (Bug ID 7753)
Workspace layout: When saving and reloading a layout file, the width of the network
objects sidebar slightly diminshes. If the window sizes read from a layout file do not
match the current screen size, automatic adaptation of window sizes and positions
is still to be improved. (Bug ID 7641)
Workspace sidebars: Sidebars can be docked and tabbed to one another, but some
configurations are currently not supported. (Bug ID 7650)
