Mobility Data Specification (MDS) is a widely used, open, standardized Application Programming Interface (API) for exchanging data between micromobility operators and public sector agencies. It has been adopted by more than 90 agencies across the world and by most major mobility providers. The inclusion of detailed, trip-specific data has been controversial, due to privacy concerns; however, agencies can choose which portions to implement, and providers support the use of a single reporting standard across cities.

MDS 1 currently has three sets of APIs:

  • Provider: Implemented by mobility providers and used by public agencies. It is how providers report historical data to these agencies
  • Agency: Implemented by public agencies and used by mobility providers. It is generally accessed at the start of each vehicle trip and is how the providers send real-time updates, such as new vehicle registrations and location data
  • Policy: Implemented by public agencies and used by mobility providers. Allows providers to query for information about rules and regulations affecting their operations.

Various open-source software tools have been developed to support the use of MDS.
