# MMTIS

> MMTIS (Multimodal Travel Information Services) is the EU framework, set out in Commission Delegated Regulation (EU) 2017/1926, that makes travel and traffic data available so journey planners can combine modes of transport such as train, bus, tram, ferry, bike sharing and car sharing into one trip.

## Key facts
- Legal basis: Delegated Regulation (EU) 2017/1926, supplementing ITS Directive 2010/40/EU. The ITS Directive was revised by Directive (EU) 2023/2661.
- Each EU member state runs a National Access Point (NAP) where transport data is published and discovered.
- Data covers static data (stops, lines, timetables, fares, networks), dynamic data (delays, disruptions, shared vehicle availability) and metadata.
- Main data formats: NeTEx (timetables, networks, fares), SIRI (real-time), Transmodel (reference model), GTFS and GTFS Realtime, GBFS (shared mobility), DATEX II (road traffic).
- Requirements were phased in between 2019 and 2023.
