Visum offers various possibilities to compare and transfer networks and version files:
- Version comparison (Version comparison)
- Model transfer files (Model transfer files)
Version comparison
To compare transport networks, two variants of version comparison are provided:
- Version comparison with transfer of selected direct attributes
- Version comparison with comparison network loaded in the background
In contrast to the first variant, which includes the transfer of selected attributes into the opened version, the second variant builds relations to the loaded network in the background. This means that all attributes of the loaded network are visible in the opened version. Additionally to the existing relations to other objects (for a node, for instance, to the in-links, out-links, turns etc.) another relation to the loaded network will appear in the attribute selection windows.

Note: In the directory C:\Users\Public\Documents\PTV Vision\PTV Visum 2025/Examples, you can find an example of use on this topic. The Version Comparison example demonstrates how version comparisons can be used to analyze the model results of different scenarios. |
Model transfer files
A model transfer file allows recording the modifications required to transfer a model, i.e. a combination of network data and OD demand data, to another model. You generate the model transfer file from two version files, whereby data can be limited to selected network object types or attributes. You can exchange modifications between the different version files at any time, and equally maintain several scenarios.
