Converting the paths of a path set or demand segment

When converting paths of a demand segment, a maximum of 100 marked paths can be converted.

1. Select the paths that you want to convert (Selecting paths).

2. Right-click in the network display.

The PrT paths shortcut menu opens.

3. Select the Convert entry.

The Parameters: Convert paths window opens.

Tip: You can also call the procedure via the Calculate > Procedure sequence > operation Convert paths menu.

The elements in the window differ depending on whether you called the window via the shortcut menu or in the Procedure sequence window.

Note: Note that the assignment paths of a demand segment are highly compressed as opposed to user-defined PrT paths. Conversion from these paths as well as storage in user-defined path sets require a great deal of memory and runtime and can only be carried out to a limited extent in larger networks. Paths from a LUCE assignment cannot be converted due to the different data structure.

4. Make the desired changes.

Description

Source of conversion

In the drop-down list, select the path set or demand segment, whose paths you want to convert.

Note

If you call the procedure via the shortcut menu, this selection will not be provided.

Time interval

Here you can select a time interval. The volumes of the selected time interval will then be converted.

Selection

Here you can specify, whether all paths or just the flow bundle routes or the relations of the OD pair filter shall be converted.

Factor

Here you can enter a factor by which the volumes of the origin paths will be multiplied.

Target of conversion

From drop-down list, select the path set or the demand segment to which the paths will be transferred.

Time interval

Here you can select a time interval, to which the volumes will be transferred.

Conflict handling

If the origin path and the destination path are identical, the following options are provided.

Replace all

All existing destination paths will be deleted before the conversion.

The volumes of the origin paths and the volumes of the existing destination paths will be added up.

Overwrite

Identical destination paths will be overwritten by the origin paths.

5. Confirm with OK.

The paths are converted.

Note: If you convert paths resulting from an assignment, the program always creates paths which start and end at a zone.
