New Mobility Database API to Access Transit Data From Around the World

Accessing transit data from around the world just got easier! Open, discoverable data is key to providing riders with up-to-date traveling information. MobilityData has created a new API for the Mobility Database, a public directory of over 2000 General Transit Feed Specification (GTFS) feeds from around the globe. The API was a collaborative effort with partner Two Sigma Data Clinic, and supported by funding from the U.S. Federal Transit Administration. This new API lays the foundation for even more planned improvements to the Mobility Database later this year, including a new user interface.

“We’re working to make the Mobility Database the definitive open data platform for GTFS globally,” said Eric Plosky, Executive Director of MobilityData. “This API is a key step to ensure that journey planners and researchers can easily discover quality GTFS data from all over the world.”

The new API allows users to:

  • Search for feeds based on their location or transit provider
  • Get the latest version of a GTFS feed
  • Get historical versions for a specific GTFS Schedule feed after February 8th 2024
  • Check if a GTFS Schedule feed has been updated before fetching the latest version

Collaboration continues to be a critical part of improving data standards.

“As avid users of GTFS data, Data Clinic has navigated challenges of accessing feed data and metadata at scale while developing tools to analyze climate-resiliency and subway crowding within transit systems. Our partnership with MobilityData in developing this API underscores our commitment to enhancing access to transit data. We look forward to contributing further to this exciting project and are thrilled to be part of the open-source community around GTFS,” said Kaushik Mohan, data scientist at Two Sigma Data Clinic.

This effort is another great example of the importance of cooperation as MobilityData works to improve transportation through data!
