The data need to be available as text file in either single-row format or multi-row format which can be read in Visum.
- Single-row survey data files contain one data record per row (Format of a single-row survey file).
- Multi-row survey data files contain the paths in path leg data format. Each row includes a path leg (Format of a multi-row survey file).

Notes: When reading survey data, data records with a departure time past midnight (24:00 to 48:00) are permitted. Such data records are converted to format 0-24 for output after plausibilization, departure times >24:00 then fall on the next valid day. The boarding and alighting stops stated in the interview data records of the surveyed line must exist in the checked network. If this is not the case, the record in question is ignored. If one of these stops is deleted after reading survey data from file, all paths from/to these stops will get lost. |
