Using model transfer file (*.trax)

You can save the differences between two Vissim networks to a model transfer file (*.trax)(Creating model transfer files). Generally, one network models the base, while the other network models the target. One of the networks can be the one currently opened.

You apply the model transfer file (*.trax) to a network file (Applying model transfer files). The network file must be opened in the Network editor. When applying the model transfer file (*.trax), you transfer its network data (*.trax) to the network opened in the Network editor.

Application example for Scenario management

You can transfer two network variants to Scenario management: The network with the base is placed under Scenario management. You then apply the model transfer file to this network. This is how the second network selected is created:

1. Generate the model transfer file (*.trax) based on network A and B (Creating model transfer files).

2. Then you place network A under Scenario management as scenario 1 (Placing a network under scenario management)..

3. Copy Scenario 1.

4. Rename the copied scenario to Scenario 2.

5. Open scenario 2 in the Network editor.

6. Apply the model transfer file to scenario 2 (Applying model transfer files).

Selecting network file and viewing changes compared to opened network

1. From the File menu, choose > Compare and Transfer Networks > Compare Opened Network with Network File.

The Select comparison network window opens.

2. Select the desired Vissim network file for which you want to view changes compared to the currently opened network.

3. Click the Open button.

In the Network editor, in a Difference display, the changes are highlighted in color. To enable the Difference display, in the window of the tree structure, on the toolbar, select the Difference display in network editor on/off button. The window Compare opened network with <path and name of network file> opens. A tree structure shows network objects and attributes:

modified (blue)
new (green)
deleted (red)

The Network editor and tree structure are synchronized by default: When you select a new or modified network object in the Network editor, it is highlighted in the tree structure.

4. To deactivate the Difference display in the Network editor, in the tree structure window, on the toolbar, click the Difference display in network editor on/off button.

5. To select a different network for comparison with the currently opened network, in the tree structure window, click the toolbar button and select the desired network.

The tree structure and the Network editor are updated.

Showing changes to scenarios or modifications

When you create a network under Scenario Management, you can compare it for differences to the base network. To do so, open a window with a tree structure. You can also select another scenario for comparison and show the changes between the two scenarios in the tree structure. You can also use the tree structure to show changes made to a modification.

1. Under Scenario management, in the Project explorer, right-click the desired scenario or modification.

2. From the shortcut menu, choose Show changes for scenario/modification.

modified (blue)
new (green)
deleted (red)

The Network editor and tree structure are synchronized by default: When you select a new or modified network object in the Network editor, it is highlighted in the tree structure.

3. To deactivate the Difference display in the Network editor, in the tree structure window, on the toolbar, click the Difference display in network editor on/off button.

4. To select a different network for comparison with the currently opened network, in the tree structure window, click the toolbar button and select the desired network.

The tree structure and the Network editor are updated.
