CHOUETTE is an open source software financed by the French Ministry of Ecology, Sustainable Development, Transport and Housing (MEDDTL).
Its main purpose is to capture and exchange data, describing the planned public transport timetables and network topology, i.e. the planned public transport service offer in order to facilitate the implementation of multimodal traveler information systems.
The supported exchange formats are:
- NeTEx (fully compatible with Transmodel V6)
- the French NEPTUNE Standard (NFP 99506) – based on Transmodel V5.1,
- GTFS and CSV.
