The U.S. Department of Transportation releases the Connected Vehicle Reference Implementation Architecture (CVRIA) Version 2.0

The U.S. Department of Transportation (USDOT) Intelligent Transportation Systems Joint Program Office (ITS JPO) is pleased to announce that the Connected Vehicle Reference Implementation Architecture (CVRIA) and the Systems Engineering Tool for Intelligent Transportation (SET-IT) have been updated to Version 2.0 and are available at the CVRIA Website:

The CVRIA provides the basis for identification of key interfaces across the connected vehicle environment and identification and prioritization of USDOT support for standards development activities. The CVRIA also supports policy considerations for certification, standards, core system implementation, and other elements of the connected vehicle environment. This new version of the CVRIA provides physical, functional, enterprise, and communication viewpoint enhancements, as well as covers international applications.

SET-IT provides a single software tool that integrates drawing and database tools with the CVRIA so that users can develop project architectures for pilots, test beds, and early deployments.

The SET-IT 2.0 update aligns with CVRIA Version 2.0 and addresses issues reported by SET-IT 1.0 users. SET-IT 2.0 now supports the generation of "Communications View" drawings and tables. The SET-IT software tool is available for download from the CVRIA website:
