The Open Data Program is an initiative by AC Transit to make public information accessible and usable by a wide range of users. To achieve this, AC Transit will adopt the following best practices:
- Proactively release useful eligible AC Transit data in open formats, without restrictions, and accessible to all.
- Regularly publish high‐quality and machine‐readable data.
- Evaluate the usefulness of data sets made available through the program.
- Support innovative and ethical uses of data by peer agencies, the public, and partners.
- Protect sensitive information from unauthorized disclosure, while minimizing limitations on the disclosure of public information.
The AC Transit Data Governance Advisory Committee provides oversight for developing and implementing these best practices.
