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 ridership data files contain one data set per row (Format of a single-row ridership data file).
- Multi-row ridership 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 ridership data, data sets with a departure time past midnight (24:00 to 48:00) are permitted. Such data sets 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 sets of the surveyed line must exist in the checked network. If this is not the case, the data set in question is ignored. If one of these stops is deleted after reading ridership data from file, all paths from/to these stops will get lost. |
