You can import an existing path sequence items list as attribute file *.att into a path sequence set. Here it does not matter whether the data stems from a disaggregated demand model or from another Visum network.
1. From the File menu, choose Import > Path sequences.
The Import path sequences window opens.
2. Next to File name, click the 
icon.
3. Select the desired file.
4. Click the Open button.
5. From the drop-down list Path sequence set, select the entry into which you want to import the data or click the Generate button to create a new path sequence set.
6. Confirm with OK.
The path sequence items of the desired file are imported into the current network. The import is not additive. Therefore, all existing path sequences will be deleted.
Structure of the attribute file
The following columns must be provided in the file:
|
Note: The file must be sorted by the first four columns in the specified order so that it can be imported. |
- Origin zone number
- Destination zone number
- Path sequences index
- Index
- Zone number
The following columns are read in if they exist:
- Path sequence\volume
Note: If the volume is not specified, the default will be 1.
- Path sequence\name
- Path sequence\AddVal
- To-demand segment code
- Departure
- Arrival
- Path sequence activity code
- Person number
- Schedule number
- Tour number
|
Note: To save storage space, you should only create column names for the attributes Arrival, Departure, and Path sequence\name if they have attribute values. For each single relation, the program saves existing values, even if the value is empty. |
The following columns are not read in:
- Path sequence set no
- Matrix
