transitland

Transitland is an open data platform and registry for public transit feeds. It aggregates GTFS (General Transit Feed Specification) data from transit agencies and other providers to create a global catalog of transit information and makes it accessible through a web interface and a RESTful API.

The platform models data with entities such as agencies, routes, trips, stops, and shapes. It supports standard GTFS data and GTFS-realtime feeds where available, allowing users to search for feeds by region, browse metadata, and query schedules via the API. Developers can build maps, apps, or analyses using the published feeds.

Transitland is community-driven and open source. Data is contributed by participating operators and the community, and the project emphasizes openness, interoperability, and reproducibility, relying on shared GTFS formats to enable data sharing across jurisdictions.

By providing a centralized registry and API, Transitland serves researchers, journalists, planners, and developers who need discoverable transit data, and it supports workflows for publishing, validating, and visualizing networks.
