OpenMobilityData: the mobility databse

OpenMobilityData (formerly known as is an extensive archive of GTFS data for software developers, transit agencies and more. Browse and download official GTFS & GTFS-realtime datasets from around the world.

The Mobility Database

To facilitate more reliable passenger information and interconnection information, MobilityData is developing and hosting a free, global database of stable identifiers for mobility entities (e.g., stops, lines, networks), which allow the definition of links between datasets from different sources and across data formats. Structured as a semantic database with a linked data model, the database also allows properties and relations to be saved (e.g., stop names, stop belonging to a line).

Canonical GTFS Validator

The Canonical GTFS Validator is an open-source project that aims to provide an easy solution for validating GTFS feeds that contain the new extensions.
