#### Field: derived_capacity

HaCon does not evaluate this field, as we do not know the exact system topic behind it.

| Code   | Descripption               |
| ------ | -------------------------- |
| 'LWD'  | Counted by counting system |
| 'LWDA' | Derived                    |
| 'LWA'  | Derived                    |
| 'ROOT' | Derived                    |
| 'LW'   | Derived                    |

## Remarks

The content of the "line" field may differ from the GTFS data in the space area. Furthermore, the individual journeys and times may differ from the journeys in the GTFS data. Here the user may have to match "soft" and "intelligent".
