Connected Vehicle Reference Implementation Architecture
The Systems Engineering Tool for Intelligent Transportation (SET-IT) Version 0.1.5 is available as a download from the Tools page. This version adds layer 0 and layer 1 physical diagram support and includes various usability improvements. See the Tools page and Readme file for more details.
Presentation Material from the
CVRIA Workshop in San Francisco
held February 19-20, 2014
In continuation of CVRIA efforts, USDOT will present and seek input on candidate Connected Vehicle interfaces for standardization at a free public workshop in San Francisco, California on February 19-20, 2014. Read more...
Feedback is encouraged as the CVRIA is developed and maintained. Key stakeholder activities include:
- Reviewing the architecture viewpoints
- Reviewing the standards development plan
- Providing inputs for policy development and review policy options
Please use the Contact Us page to ask questions or provide comments to the team.
Welcome to the Connected Vehicle Reference Implementation Architecture (CVRIA) Website! This site is your tool for reviewing, providing feedback, and using the architecture content for standards and project development. CVRIA is being developed as the basis for identifying the key interfaces across the connected vehicle environment which will support further analysis to identify and prioritize standards development activities. CVRIA will also support policy considerations for certification, standards, core system implementation, and other elements of the connected vehicle environment.
As shown in the figure, CVRIA is developed in 4 Viewpoints:
- Enterprise - Describes the relationships between organizations and the roles those organizations play within the connected vehicle environment
- Functional - Describes abstract functional elements (processes) and their logical interactions (data flows)that satisfy the system requirements
- Physical - Describes physical objects (systems and devices) and their application objects as well as the high-level interfaces between those physical objects
- Communications - Describes the layered sets of communications protocols that are required to support communications among the physical objects that participate in the connected vehicle environment
Another way to view the architecture is from the perspective of the connected vehicle safety, mobility, environmental, and support applications. Each application page shows the subset of each of the viewpoints that pertain to that application.
The project is sponsored and led by the USDOT's ITS JPO, under the management of the ITS Architecture and Standards Programs and in cooperation with the Systems Engineering and Test Bed Programs.
