Notes: Paths are generated automatically for each demand segment if you calculate a PrT assignment. If you delete the assignment results, the paths generated this way will be deleted again. You can also insert paths manually and assign them to demand segments or path sets. Paths that are allocated to paths sets are not deleted when deleting assignments. If you manually insert paths which are assigned to demand segments, the attributes deviate (Properties and options of PrT paths). These paths will also be deleted if an assignment is deleted for the demand segment. |
1. In the Network editor window, click the Insert mode icon 
.
2. In the Network window, click the PrT paths button.
The Create window opens.
3. Select the Path entry.
4. Click in the network display.
The Select the path set window opens.
5. In the drop-down list, select the desired path set for which you want to create a path.
|
Note: You can select demand segments or path sets. If you create a path for a demand segment (Properties and options of PrT paths), the path needs to start and end at a zone. |
6. Confirm with OK.
The Edit course window opens.
7. Click the node or zone at which the path shall start and hold down the mouse button.
|
Notes: A path needs to start and end at a node or at a zone. If the path starts at a node, it also has to end at a node. If it starts at a zone, it must end at a zone. Main nodes can also be items of paths. They can, however, only be selected via the partial nodes. |
8. Drag the mouse to the next zone or node via which the path shall run and release the mouse button.
|
Note: If required, in the Edit course window, click the Zoom button to enlarge the section with the course. |
9. If required, proceed in the same manner to create any other sections you wish to create.
|
Note: If required, in the Edit course window, click the Undo button to delete the last section of the path course. |
10. Drag the mouse to the desired endpoint of the path and release the mouse button.
|
Tip: You can also drag the mouse from the first zone or node to the desired endpoint. The program will then suggest the best path based on the set search criterion (Paths: specifying parameters for the path search). |
11. In the Edit course window, click the OK button.
|
Tip: You specify settings for the newly inserted network object directly in the Quick view (Paths) window. The attributes of PrT paths are described here (Properties and options of PrT paths). If you want to display the Edit path window when inserting the object, you can right-click the PrT paths button in the Network window, activate Show dialogs when inserting objects, and directly adjust settings for the newly created network object. |
The path is inserted.
|
Note: You can edit the course of a path later (Editing the course of a path). |
Paths: specifying parameters for the path search
1. In the Edit course window, click the Parameters button.
The Parameters: Path search window opens.
2. Make the desired changes.

Reference transport system |
Select the desired transport system |
|
Use also closed links for routing |
If the option has been selected, the links closed to the transport system will be taken into account, as if they were open to the transport system. |
|
Use also closed turns for routing |
If the option has been selected, the turns closed to the transport system will be taken into account, as if they were open to the transport system. |
|
Search criterion |
From the drop-down list, you can select a criterion for the path search. The search finds the best path each between two marked (fixed) points. Link length (direct distance) Direct distance link length from the origin to the destination stop point Link run time Is calculated from the transport system speed of the links Time from speed def. by link type Is calculated from the transport system speed specified for the respective link type Link length Calculated link length if not manually adjusted by the user |
3. Confirm with OK.
