The data that are shared through the ShareStreets platform include city mobility and transportation data from companies and city governments that are members of the National Association of City Transportation Officials (NACTO).
The data is shared to the SharedStreets platform according to a data standards set by the organization. The purpose of these standards are to "convert today’s ad hoc and disparate data transportation data from public and private sector sources into a mutually readable, shared, global standard for the first time, providing a universal language for digitally describing every aspect of city streets, opening a new market to private sector innovators, and eliminating of the need to manually “clean” and collate data sources, saving crucial public funds."

SharedStreets is created by the Open Transport Partnership, a non-profit organization that facilitates public-private partnership around transportation data. It is a project that aims to support data sharing to inform policymaking, through software, digital infrastructure, and governance models.
