Technical information and requirements

Current information on the technical requirements for the current Vissim version can be found on our website PTV Vissim FAQs. The following information, e.g., is essential:

Entry (#3): What are the hardware and software requirements for Vissim?
Entry (#6): Which graphics card has the best performance with Vissim 3D?

Criteria for simulation speed

The speed of a Vissim simulation primarily depends on the following criteria:

Number of vehicles and/or pedestrians used simultaneously in the network
Number of signal controls
Type of signal controls
Number of processor cores deployed
Computer performance. On a faster computer, a simulation will run faster with the same network file.

Main memory recommended

Min. 4 GB RAM The memory requirements may be considerably higher for the following use cases:

Networks with many dynamically assigned paths
Large applications with many pedestrian areas

Graphics card requirements

If under User Preferences > GUI > Graphics, the graphics driver OpenGL 3.0 is selected, make sure that your video card at least supports OpenGL 3.0.
Ensure that the latest driver update has been installed for your graphics card. This way, you will avoid visualization problems when using the 3D mode. For many graphics adapters, you can download update drivers from the Internet.

Note: Should any problems arise with the 3D display in Vissim, first install the latest driver update for your graphics card before you contact PTV Vision Support.

Interfaces

Not all program interfaces are by default part of your Vissim license. They might be available as add-on modules (Add-on modules programming interfaces (API)). Add-on modules and their documentation are saved to the folder ..\Vissim 11\API of your Vissim installation.

Number of characters of filename and path

With Windows, the number of characters of a path, including drive letter and filename, is limited to 260.
With Windows, the number of characters of a path is limited to 248.
In Scenario Management, the length of the path to the project directory is limited to 214 characters.
Make sure that your project files are not saved to any paths longer than that. This for instance includes the following paths:
Name of *.inpx network file and path to the directory where the network file is saved.
Directories and subdirectories you create during a project Files saved to these directories
Directories and subdirectories that Vissim creates automatically or to which Vissim saves data, e.g. for scenario management or evaluations.
