In the flow bundle display, you can filter paths by a traffic type (Internal traffic, Origin traffic, Destination traffic, Through trips, External trips, or Bypassing internal trips). To do so, set links, stops, or objects of the line hierarchy active or passive (Fundamentals: Flow bundle definition through selection of traffic types).
The following two examples illustrate the settings for traffic type-based flow bundles.
Displaying through trips using a flow bundle
In the following example, all paths which traverse at least one inner city link between start and end at an external zone are filtered with the aid of a traffic type-based flow bundle.
1. Set the desired links within the inner city to active (Using filters to set network objects active or passive).
2. Set the desired links within the external zone to passive.
3. On the Graphics menu, click Flow bundle.
The Graphics tools (Flow bundle) window opens.
4. Under Term type, select the traffic type PuT.
5. In the Add special conditions section, choose option Insert active links as condition when selecting links.
|
Note: The option is available only if there are passive links in the network. |
A new Active links row is inserted.
6. Click the 
icon in the Condition column.
The Edit flow bundle term window opens.
7. On the Traffic types tab, select the traffic type Through traffic.
8. Deselect the other options.
|
Note: You can set several options as active, however not all at once. |
|
Description |
|
|
Internal trips |
Filters paths which only use active objects |
|
Origin demand |
Filters paths starting with an active object and ending with a passive object |
|
Destination demand |
Filters paths starting with a passive object and ending with an active object |
|
Through trips |
Filters paths which start and end with a passive object and use at least one active object in-between |
|
External trips |
Filters paths which do not use active objects |
|
Bypassing internal trips |
Filters paths which start and end with an active object and use at least one passive object in-between |
9. Confirm with OK.
The settings are applied.
10. Insert further filter criteria, if required.
11. Click the Execute symbol 
.
The flow bundle filters the Through traffic.
|
Notes: Visum saves the information on which links are active during the flow bundle execution. A status that was subsequently changed in the network will be indicated by red text and a tooltip in the Graphics tools (Flow bundle) window. You can display the volumes graphically in the network (Setting graphic parameters for the display of flow bundles) or in a list (Displaying flow bundles in lists). |
Displaying internal traffic with a flow bundle for active time profiles
You can filter paths by the status of the lines used (active/passive). The program then takes into account which path legs are used by an active or passive line. In the following example, the filter determines all passengers which use long-distance trains on all path legs.
1. Set all long-distance lines to active (Working with hierarchical filters).
2. On the Graphics menu, click Flow bundle.
The Graphics tools (Flow bundle) window opens.
3. Select the traffic type PuT below Term type.
4. In the Add special conditions section, choose option Insert active lines as condition when selecting links.
|
Note: This option is available if at least one object of the line hierarchy is passive and at least one other object is active (Working with hierarchical filters). |
A new Active lines row is inserted.
5. Click the icon in the Condition column.
The Edit flow bundle term window opens.
6. On the Traffic types tab, select the traffic type Internal trips.
|
Note: This option filters paths which use active objects only. |
7. Deselect the other options.
8. On the Filtering tab, click the Active lines.
9. Confirm with OK.
10. Click the Execute button.
The flow bundle filters the Internal trips.

Notes: Visum saves the information on which network objects are active during the flow bundle execution. A status that was subsequently changed in the network will be indicated by red text and a tooltip in the Graphics tools (Flow bundle) window. You can display the volumes graphically in the network (Setting graphic parameters for the display of flow bundles) or in a list (Displaying flow bundles in lists). |
