- General Transit Feed Specification (GTFS)
The General Transit Feed Specification (GTFS) is a data specification that allows public transport operators to publish their transit data in a format that can be consumed by a wide variety of software applications. Today, the GTFS data format covers both static and real-time data and is used by thousands of public transport providers.
Many public transport operators release this data as open data. A good source of GTFS data in the UK is Passenger’s open data website.
