Once you have specified that an attribute is time-varying, you need to enter the data for the time variation. Here you specify the time during which the variation applies and the value which is used for the attribute during the specified time.
Time-varying attributes of links are edited in the Network editor window . Time-varying attributes of nodes, main nodes, turns and main turns are edited in the junction editor. 
.
Editing time-varying attributes of links
1. In the Network editor window, click the Edit mode icon 
.
2. In the Network window, click the Links button.
3. In the network, click a link for which you want to specify time-varying data.
The Edit link window opens.
4. Select the Time-varying attributes tab.
|
Notes: The tab lists all attributes that you have inserted at the network object as time-varying attributes (Creating time-varying attributes). For links and turns, you need to specify the attributes data for each direction. Use the Transfer changes to opposite direction option when editing both directions. |
5. Then click the 
Create time-varying attribute symbol.
The Create time-varying attribute at <Network object> window opens.
6. Make the desired changes:
|
Note: Depending on the network object, there are different elements are available. You can change the attribute values of time-varying attributes directly in the table. |
|
Element |
Description |
|
|
Inserts a time-varying attribute. |
|
|
Duplicates the selected time-varying attribute. |
|
|
Deletes the selected time-varying attribute. |
|
Attribute |
Name of the selected time-varying attribute Click this button to select a time-varying attribute from the ones you created for the network object type (Creating time-varying attributes). |
|
Periodical |
If the option has been selected, the allocated deviant value of the attribute will be effective every day of the selected Valid day within the time range specified. This option is only provided if a calendar has been set. |
|
Valid day |
Use the list to select a valid day. The selection depends on the calendar settings (Specifying a calendar and valid days). |
|
From To |
Specify a starting time and an ending time of the deviant attribute value. As From - To time slot, you can enter a time interval between two points in time (also stretching over several days if a calendar is in use). When using the Periodical option, you can enter the combination of a valid day and a time interval (within a day). |
|
Value |
Specify an attribute value. This deviating attribute value applies at the specified time. |
|
Optional descriptive attributes |
You can specify additional descriptive attributes for the respective time-varying attribute. Name Name of the additional attribute AddValue Attribute for entering additional values |
7. Confirm with OK.
|
Tip: In lists you can perform a copy-and-paste operation to transfer the values of time-varying attributes to other network objects. |
