With this functionality, you can generate link attribute values from the existing values of a turn attribute or main turn attribute.
The following rules apply:
- If the two nodes of a link are not part of a main node, turn attributes are allocated to the link attributes.
- If the link is an inner link, i.e. both nodes of a link are part of the same main node, turn attributes are allocated to the link attributes.
- If one node (node 1) of a link is part of a main node and the other node (node 2) is not part of a main node, the values of the main turn (node 1) and the values of the turn (node 2) are used.
- If one node (node 1) of a link is part of a main node and the other node (node 2) is part of a different main node, only the values of the main turns are used for the calculation.
|
Notes: A prerequisite is that for turns, volume data is available as turn attributes. You can also generate link attribute values based on other attributes of turns at the From node or To node of the link. |
You can execute the functionality for all, all active links, or links marked in the network editor.
Editing all or all active links
1. If required, set the links active whose link attributes you want allocate the values of turn and main turn attributes to via
- the spatial selection (Setting network objects active/passive via the spatial selection) and/or
- filter criteria (Using filters to set network objects active or passive).
The selected links are active.
2. In the Network window, right-click the Links button.
The Links shortcut menu opens.
3. Select the Calculate link attribute from turn attribute entry.
The Calculate link attribute from turn attribute window opens.
4. Make the desired changes.

Link attribute |
Use the button to select the attribute, to which you want to allocate the values of a turn attribute. |
|
Set to |
In the drop-down list, select the desired entry. Note The attribute values of each node of the link are compared and the value is determined based on the selected option. |
|
Turn attribute |
Use the button to select the attribute based on which you want to generate the link attribute data. |
|
Main turn attribute |
Use the button to select the attribute based on which you want to generate the link attribute data. |
|
Add |
If the option has been selected, the determined attribute values and already existing link attribute values will be added up. |
If the option has been selected, the value of the selected attributes of all active links will be replaced.
If the option has not been selected, the value of the selected attributes of all links will be replaced.5. Confirm with OK.
The new values for the selected link attribute are determined.
Editing marked links
1. In the network, mark all links whose link attributes you want assign the values of turn and main turn attributes.
2. Right-click in the network display.
A shortcut menu opens.
3. Select the Calculate link attribute from turn attribute entry.
4. Make the desired changes.
5. Confirm with OK.
The new values for the selected link attribute are determined.
