Loading ridership data

The "Read ridership data" procedure allows you to import survey data from an attribute file (*.att). This is a *.csv file with a header specific for Visum. Ridership data, like other network objects, can alternatively be read additively via a network file (*.net), imported via a database, generated via COM, or created interactively in the list.

Note: If you save an empty ridership data file, you create an empty attribute file that contains the necessary header. You can then reopen attribute files created in this way in Visum.
