The Mobility Database Catalogs is a list of open mobility data feeds from across the world. You can learn more about the Mobility Database and its API here.
You can see our API code and infrastructure here.
To search feeds easily, you can download the CSV spreadsheet. If you want to filter for specific types of feeds, you can learn how to here.

If you're only interested in browsing the feeds or pulling all the latest URLs, download the CSV. You can cross reference IDs from the Mobility Database, TransitFeeds and Transitland with this ID map spreadsheet.
If you are consuming the spreadsheet, we recommend downloading a new version every time you use it, since the latest.url is occasionally updated to match any changes made to the provider and subdivision name within the feed file.
Updating the CSV is a community effort. Contributors either create a PR here directly or they submit an update through the form, which MobilityData then adds as a PR within approximately a week of submission. You can look at the PR history to see how frequently there are updates, and we usually do updates 1-3 times a month.
Contains the feeds of the Mobility Database Catalogs. Every single feed is represented by a JSON file. The feeds can be aggregated by criteria using our tools.operations functions.
Contains the tools to search, add and update the feeds. The tools.operations module contains the project operations (get, add and update). The tools.helpers module contains helper functions that support the tools.operations module. The tools.constants module contains the project constants.
Contains the JSON schemas used to validate the feeds in the integration tests.
