Technical information and requirements

Current information on technical requirements of the current Vissim version:

• On our webpage  System requirements for the PTV Vision software products
• On our webpage  PTV Vissim Knowledge Base.

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 > User interface > 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 and check the 3D display afterwards 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 (Programming interfaces (API)). Add-on modules and their documentation are saved to the directory ..\Vissim 2024\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.
