A guideline to help transportation agencies improve their roadway and traffic data inventories, allowing extraction of such characteristics as connectivity of network elements. MIRE provides a platform for a common base to build travel model networks.

To encourage greater uniformity, the National Highway Traffic Safety Administration (NHTSA) and the Governors Highway Safety Association (GHSA) cooperatively developed a voluntary data collection guideline in 1998. The MMUCC guideline identifies a minimum set of motor vehicle crash data elements and their attributes that States should consider collecting and including in their State crash data system.

The Open Connectivity Foundation is working to secure interoperability for consumers, businesses, and industries by delivering a standard communications platform; a bridging specification; an open source implementation; and a certification program allowing IoT devices to communicate regardless of form factor, operating system, service provider, transport technology, or ecosystem.

There are a multitude of freight databases, both public and private, that do not conform to any uniform standard or ontology. This makes the creation of one single authoritative ontology challenging, as the individual data sources do not and will not share a common vocabulary.

SIRI is an extensible and modular standard allowing for C2C communications, agency-to-public communications, and agency-to-infrastructure communications. SIRI allows for the structured exchange of real-time information about schedules, vehicles, and connections with general informational messages related to the operation of the services. SIRI defines functional services including:

ATIS/US Ignite, through their Smart City Data Exchange Initiative, have brought together smart cities' leaders and industry experts to tackle data sharing issues and work on a common framework for “the secure and interoperable exchange of data beyond city operational boundaries.” Their Smart Cities Data Sharing Framework

SCIRA is a project of the Open Geospatial Consortium (OGC) Innovation Program sponsored by the US Department of Homeland Security (DHS), Science and Technology (S&T). The SCIRA pilot demonstrations and reports were finalized in January 2020, and the toolkit and guides were expected to be publicly released in 2020.

TCIP is an extensible and modular standard allowing for data exchange between transit business systems, subsystems, components, and devices. It covers C2C, agency-to-public, agency-to-infrastructure, and system-to-system communications. The benefits extend beyond vehicles, operations, and passenger information to business systems and subsystems noted above.

The Transit ITS Data Exchange Specification (TIDES) is a conceptual framework for accessing and managing transit agency ITS data. TIDES includes a set of common data APIs that provide access to the different aspects of ITS data (e.g., raw data from vendor systems, secondary data sources that integrate and aggregate the ITS data).
