This suggests that another setup or Windows update is running at the same time. Please run the Vissim setup again after the other setup/update has finished.Relevant version: Vissim 6.00
Symantec Endpoint Protection (SEP) is installed. This problem is fixed in Symantec Endpoint Protection 11 Maintenance Release (MR) 3.
Yes. There ist a 32-bit and a 64-bit edition available for Vissim that both work with a 64-bit operating system. The 64-bit edition runs only on 64-bit operating systems but enables the use of more than 3 GB of RAM.
Unless you work with networks that need access to additional RAM, we recommend to install the 32-bit edition of Vissim as there are a few limitations with the 64-bit edition:
We recommend graphics cards of the AMD Radeon series (for Desktop computers e.g. Radeon R7 260). AMD FirePro cards are more expensive for the same performance (a FirePro W5100 is slower than a Radeon R7 260).
Nvidia GeForce graphics series with Fermi or Kepler architecture (400 and later, e.g. GeForce GTX 750) are okay when using the Vissim command line parameter "-notwosidedlighting". This dramatically increases 3D performance but unfortunately reduces image quality of some 3D models.
Nvidia Quadro cards with Fermi or Kepler architecture have good 3D performance even without "-notwosidedlighting". However, they are more expensive for the same performance with Vissim (a Quadro K4000 is slower than a GeForce GTX 750).
For Notebooks it's important to have a dedicated graphics chip, not only onboard graphics. Even the latest Intel HD4000 graphics is really slow for 3D visualization.
It is also important to use the latest graphics driver that is available either from the notebook or graphics card manufacturer's website.

This message indicates that the expiry date of your Vissim version is reached (e.g. in a lease, demo or test version). If you feel that you get this message in error, please contact our customer service via e-mail at firstname.lastname@example.org.
In addition to the typical specifications of a common PC, these are the main requirements for the current Vissim version:
Either one of the following Microsoft® operating systems is required to run Vissim:
For 32-bit operating systems Microsoft® .NET Framework 4.5 is required. (A language independent installation setup is included in the Vissim setup).
On 64-bit operating systems both Vissim editions can be operated. In order to operate the 64-bit edition of Vissim, a 64-bit operating system is essential.
E-mail support is available by means of a hotline form on the PTV website. In several areas around the globe also our distributors provide hotline support. Please check FAQ #72 for detailed hotline information.
Comprehensive default values are supplied for vehicle types and classes as well as for driving and lane change behavior. The parameters of motorized traffic originate from research work done by the University of Karlsruhe.
Vissim uses vehicle-driver-units. There are practically no limits on the number of vehicle and driver types. By default, the vehicle types Car, HGV, Bus, Tram, Pedestrian and Bike are included. Along with all their default specifications VISSIM provides a quick project start.
The model uses the psycho-physical car-following model developed by Wiedemann. It uses vehicle-driver-units that incorporate several stochastical variations. Thus there are virtually no two vehicles that have exactly the same driving behavior.
For lane change a related rule-based model is used that was originally designed by Sparmann.
Continuous development of both models ensures up-to-date driving behaviour in VISSIM.
Most likely one of the following reasons causes the problem:
In both cases the online help will not function properly.
Problem (1) is caused by a Microsoft® security patch that blocks executing help files on remote drives. To overcome this problem the easiest way is to install Vissim locally or on a virtual machine. If this is not possible or not desired, system administrator find another solution in the Microsoft® knowledge base.
To overcome problem (2), Vissim needs to be installed in a path without using any # characters.
Since Vissim 5.20 fixed time signal controls are not stored in the INP file directly any more but in a separate SIG file for each signal controller (apart from the file extension this is similar to all other types of signal controllers). Hence all SIG files referenced by an INP file need to be resident in the same directory as the INP file in order for the INP file to load correctly.Relevant version: from 5.20
All the window size and placement settings are stored in the registry. To restore VISSIM to the default settings, call VDIAG.EXE (contained in the same directory as VISSIM.EXE), go to the "Actions" tab and press "Reset windows position".
At first, these files are not essential for the simulation to run. In order to correct the error, you need to open Signal Control - Edit Controllers.... For each signal control where a SZP file is missing, go to the tab "SigTimTblConfig", delete the entry next to "Configuration file" and confirm with OK. Similarly, for each missing KFG file, delete the configuration file entry on the tab "LDP Config".
A simulation always starts with an empty network. Thus warm-up periods need to be included in order to get realistic results. This is done by enhancing the simulation period by the warm-up period and set the start of the simulation (time of day) earlier by the same amount of time. Make sure that all evaluations start after the warm-up period (by changing their start time).
Furthermore you may use the snapshot functionality which allows to start a simulation not only from the beginning but from a simulation state saved earlier. For details, please check the PTV Vissim 5.4 help > "Simulation and Test" > "Saving the Simulation State".
Yes. The Vissim Viewer can be used without a hardware lock. For more information please refer to the PTV Vissim 6 help > "Welcome!" > "The PTV Vissim Viewer". To update the Viewer to a new service pack, please check FAQ #94.
For the vehicle that does not stop most likely the end of the conflict area is not visible. This may happen e.g. if a relevant connector starts inside a conflict area. Relevant means that the route sequence of a vehicle includes traveling on that connector.
To resolve the problem try moving either the connector outside of the conflict area or shorten/split the link so that it does not overlap with the relevant connector.
In order for a vehicle to react in a conflict area it has to see the end of the conflict area. For long conflict areas it may happen that the defined number of "observed vehicles" is too low to accomodate for all vehicles (the conflict area internally is counted as vehicle as well).
To solve the problem, the minimum look ahead distance must be increased to ensure that vehicles see the end of the conflict area - independently of the number of "observed vehicles". We recommend to apply this driving behavior only to those links/connectors where it is required in order to keep the simulation speed as fast as possible.
Check if the lane where the HGV wants to change to, is closed to HGVs (button "Lane Closure..." in the link/connector window) or if the lane change to this lane is banned for HGV (button "No lane change..." in the link/connector window).
Fixed time signal control is included in the standard license. The add-on VISSIG provides additional functionality in the signal program editor beyond the VISSIM standard version. Models of several standard controllers for traffic actuated control are available as separate, independent products. Also available is VisVAP, a graphical flow chart tool to develop and edit an own vehicle actuated signal control logic including any type of special features (e.g. PT priority, railroad preemption, variable message signs on motorways etc.).
Please refer to the PTV Vissim 6 help > "Creating and editing a network" > "Modeling right-of-way without SC" > "Modeling stop signs and toll counters" > "Using stop signs for right turning vehicles even if red".
Yellow boxes can be modeled using conflict areas or priority rules. For details on priority rules please refer to the PTV Vissim 6 help > "Creating and editing a network" > "Modeling right-of-way without SC" > "Modeling priority rules" > "Examples of priority rules" > "Priority rule Example 2: Avoiding tailbacks at a junction".
Visualization of the yellow box can be done if you include it in a background graphics file. You can also load multiple background files simultaneously.
Not directly. As Vissim uses directional links, it is only possible at fixed locations and using priority rules, e.g. for a bus stopping at a bus stop. An example is included with the standard Vissim installation at "..\Example\Training\SpecialModeling\OvertakeBus_OncomingTraffic".Relevant version: up to Vissim 5.40
When using static routes, a movement is banned if there is no route assigned to that movement (if routes do exist for at least one other movement). Routes are dependent on vehicle classes thus allowing banned turns for a certain class only.
When using Dynamic Assignment, connectors may be closed to certain vehicle classes.
Even if you draw links crossing each other, the program will not recognize this as an intersection unless you model connectors or any type of junction control (signal control, conflict areas and/or priority rules).
For 3D mode you may enter a height value to any link/connector to show the different levels.
Yes, it is possible. Platooning effects can be generated by
Public transport is modelled as trams and/or buses in high detail with fixed routes. Stops and timetables are modelled as well. Waiting times at stops depend on the timetable and on a user defined random distribution for the passenger interchange times. Optionally the dwell time calculation method can be chosen which uses real passenger flows to determine waiting times. Priority on signal control junctions can be modelled completely with detection and control logic using a vehicle actuated signal controller.
Since the model is microscopic, shock waves and blocking back are modelled inherently.
Local knowledge can be modelled in Dynamic Assignment by defining different vehicle classes and allowing rat runs only for these classes.
Lane drops and gains can be modelled easily using the link parameters.
VMS and other types of traffic control can be modeled using the VAP or COM interfaces.
See also the "..\Examples" directory on your standard VISSIM installation for examples on these topics.
Yes, by using stop signs with an optional time distribution.
Route choice can be determined by the user (static routing) or computed by iterated micro-simulation using the optional Dynamic Assignment module. Routes can also be imported from the travel demand modelling software tool Visum.
Vissim has separate models for urban traffic and for motorways (car following models - Wiedemann 74 and Wiedemann 99). Motorway junctions can be modelled using the standard network elements. Merging areas have been tested and proved against HCM standards.
Any junction geometry can be modeled (signal-controlled intersections, priority junctions, merges including any type of roundabout) in Vissim.
The basic element of Vissim networks is a link (stretch of road) with one or more lanes or maximum 10 lanes. Links can be modeled exactly according to the geometry of the real junction with a precision down to one millimeter. Based on the link structure, network elements such as signal heads, conflict areas, priority rules etc. can be defined.
Yes, there are various options depending on the application:
Yes, any type of pedestrian crossing can be modelled, including zebra crossings, permitted flows (where turning vehicles need to yield to pedestrians) and signalized crossings.
See the "..\Examples\Training\SignalControl" directory on your standard VISSIM installation for examples on these topics.
For a network with three simple, 4-leg junctions the geometric model will be finished within a few hours. Coding an existing signal control depends heavily on the control logic: A few minutes for a fixed time control, several hours for modeling a complex vehicle-actuated control with public transport priority.
The largest Vissim license has no built-in limit. Therefore the network size is limited only by computer resources. Apart from the hardware, the major factors that determine the simulation speed are number of vehicles simultaneously in the network, number of signal controls and number of possible paths (Dynamic Assignment).
If you have modified your Vissim network and still want to continue to use an old path file, the option "Check Edges" in the Dynamic Assignment window must be enabled. Then the following errors might occur:
Either one of these errors means that the old structure (of the path file) cannot be safely matched with the modified Vissim network. You either need to modify your network or you need to delete the path file and let Vissim build a new one.
If the message looks like this:
"No path from parking lot 23 to parking lot 1594 can be used because of the following connector closures: 11880, for the following vehicle types: 100"
it is just a warning. It does not mean that vehicles are not placed into the network unless there is another message which states:
"No parking lot found from zone 19 with at least one path to destination zone 14. Vehicles of type 100 from the matrix file *.FMA could not be placed in the network."
Please check the following points:
This way of modeling is incorrect. You only need to have one connector linking the double-lane link with the single-lane link. Because of the route functionality of Vissim, vehicles automatically will change lanes to the one which is connected to the single-lane link - and thus there is only one possible route.
This kind of modeling is recommended both for static routes and Dynamic Assignment.
A generalized cost function is used instead of merely travel time. The link cost is the weighted sum of travel time, distance and link specific costs. The user has control over the weights that are used for each particular vehicle type.
Matrix development tools are not part of Vissim. However, it is possible to link up with Visum which provides sophisticated handling of matrices and traffic demand.
For this task you need an animated pedestrian model and V3DM. Follow the steps listed below:
AutoCAD® DWG files allow to store multiple layouts within the same file. In Vissim always that layout is used which in AutoCAD® was actived last.
On computers with both an on-board and dedicated graphics the graphics mode needs to be explicitely switched to the dedicated card for best Vissim performance. This can be done in the Nvidia Control Panel or AMD Catalyst Control Center which can be accessedfrom the System tray in the Windows taskbar or from the advanced Settings in the Display Settings from the Windows Control Panel.
If the Computer has Nvidia Optimus, Vissim is usually exectued by Default on the on-board graphics. To assign Vissim to the dedicated graphics chip, the graphics settings of your computer need to be modified as above.
Please check also FAQ #6.
The 2D visualization during a simulation run can be very slow on Windows 7® if a desktop theme with Aero (translucent glass design) is selected. If a basic theme without Aero is selected (in Control Panel - Appearance and Personalization - Personalization - Theme) the 2D visualization can be up to 9 times faster.Relevant version: up to and including Vissim 5.40
Yes. There are two options:
(Sketchup® is a 3D modelling tool. You will find in the internet a large library of Sketchup® models incl. buildings and landmarks.)Relevant version: from V3DM 1.40, from Vissim 5.20
We've experienced the best quality/size tradeoff with the x264 codec.
The video codecs are part of the operating system and hence VISSIM has no influence in what codecs are available or not. Make sure to have the desired codec(s) installed on your computer before you start VISSIM (you may use the links above to download the corresponding codec).
For succesful playback you need to ensure that the codec used for recording is also installed on the computer system where it is played back. For Windows 7 typically no additional installation is required for AVIs using the x264 codec.
Please note that for x264 there is a 32-bit and a 64-bit edition available. Choose that edition which complies with the application for recording/playback (e.g. x264 32-bit for VISSIM 32-bit). If you are unsure you may also install both editions.
As an alternative for playback you may use a media player with built-in codecs such as VLC media player.
[Please note that using these codecs and other software is entirely at your own risk and outside the scope for VISSIM support.]
Yes, using the node evaluation. For further information please refer o the PTV Vissim 6 online help > "Performing evaluations" > "Output options and results of individual evaluations" > "Evaluating nodes".
V3DM is short for "Vissim 3D Modeler" and is an additional Vissim module to
If you would like to create more complex 3D objects you need professional 3D modeling tools such as 3ds Max. For including your own pedestrian models in Vissim, please check FAQ #111.
In Vissim, static 3D objects (V3D format) can be inserted in 3D mode by right click.
Another option is to export Vissim data to 3ds Max in order to create a high-end presentation of the simulation entirely inside 3ds Max.
Yes, any background graphics that are loaded in 2D are also visible in 3D. Static 3D objects in V3D format (Vissim 3D) may be placed anywhere in the network. Since Visim 5.20 it is also possible to place Sketchup® files (*.SKP) directly in 3D mode as static object (Vissim 32-bit editions only).
Several vehicle and static 3D models are included with the standard Vissim installation in V3D format. In addition many more models in V3D format are available for download through our service area webpage (login required).
Customized models can be created/converted using V3DM (Vissim 3D Modeler - additional module, see also FAQ #61).
Yes, this is possible with the optional pedestrian module (from Vissim version 5.20).
As an alternative (without the pedestrian module), Vissim can keep track of passenger flows for each transit line and stop (without visualizing them) in order to compute the dwell times of the train/bus at a stop for realistic public transport operation.
Yes, among several bitmap formats (e.g. jpg, tif, bmp) also vector formats (e.g. wmf, dxf/dwg, shp, Mr. Sid) can be used for background graphics.
Please note that few vector formats currently are supported by the 32-bit version of Vissim only.
Please see the attribute "additional level" for sections. Using it you can measure the number of pedestrians on a ramp.Relevant version: Vissim 8.00
Yes, using the Vissim Analyzer-Reports. Level of Service of intersections based on the Highway Capacity Manual (HCM) LOS categorization for signalized intersections (Chapter 16).
Another way to calculate the LOS is to measure delay times. Delay time = additionally required time to pass a signal-controlled intersection compared to a free through route. Matching delay and level of service is done differently in every country.
For pedestrians (optional module) an LOS color code can be displayed directly during the simulation.
This warning message originates from Excel® and may come up, if the command "RunContinuous" is used. Choose one of the following solutions to avoid this message:
You need to have a SCATS®/SCOOT® system running on your computer (this is independent of Vissim and is not distributed by PTV).
For SCATS®, several files incl. WinTraff and ScatSim are needed from the "Roads and Traffic Authority" NSW, Australia.
PTV Group has extended its contract with Microsoft to bring bing maps as background map into PTV Visum, PTV Vissim, PTV Viswalk and PTV Vistro. Customers with active maintenance contract benefit another three years without additional charges from the high resolution arials of bing maps. For the software releases in 2015 (PTV Visum 15, PTV Vissim/Viswalk 8 and PTV Vistro 4) you dont need to do anything, bing maps will be enabled automatically. For older versions you need to update to the latest service packs of PTV Visum (13.00-21, 14.00-15), PTV Vissim/Viswalk (7.00-13) and PTV Vistro (3.00-06).
Most likely for one of the following reasons:
- the help file is located on a network drive
- the Vissim installation path contains an invalid character. CHM help files must not contain a # character within their file or directory path. Further characters to avoid are ?, & and +.
