USDOT updates its Connected Vehicle Reference Implementation Architecture

0

The US Department of Transportation (USDOT) Intelligent Transportation Systems Joint Program Office (ITS JPO) has announced that the Connected Vehicle Reference Implementation Architecture (CVRIA) and the Systems Engineering Tool for Intelligent Transportation (SET-IT) have been updated to Version 2.2 and are now available at the CVRIA website.

The CVRIA provides the basis for identifying key interfaces across the connected vehicle environment and supports analyses to identify and prioritize USDOT support for standards development activities. 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 covering international applications.

The SET-IT software 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 2.2 update aligns with CVRIA Version 2.2 and addresses issues reported by SET-IT users, including the connected vehicle pilot sites. In CVRIA 2.2, the separate ‘Signal Phase & Timing’ application has been removed and the ‘Connected Vehicle Map Management’ application is now, simply, ‘Map Management’. Other smaller changes have been made to support SET-IT, and the 2.2 update also provides performance enhancements and better consistency between views for diagrams and tables.

In September 2015, Iteris was awarded a US$5.8m task order from the USDOT for continued support and evolution of the National Intelligent Transportation System (ITS) Architecture and the CVRIA through 2018, extending the company’s working relationship with the agency to over 20 years. Iteris is leading the development and evolution of the USDOT’s CVRIA, which identifies key interfaces and standards for the Connected Vehicle environment, with the technology allowing vehicles to communicate with one another (V2V), as well as with transportation infrastructure (V2I). The Obama administration and USDOT believe the technology has the potential to significantly improve the efficiency of the USA’s transportation system, while enhancing the safety and user experience for all travelers.

The Connected Vehicles initiative is focused on the development and deployment of a connected transportation environment that makes effective use of multimodal systems, as well as other transformational applications that require a robust, underlying technological platform. This environment can ensure safe, reliable, interoperable system operations that minimize risk and maximize efficiencies for the traveling public. Iteris complements its working relationship with the USDOT by assuming leadership positions in many other initiatives that relate to connected and autonomous vehicle development programs.
