A coalition of industry leaders, including the 5G Automotive Association (5GAA) and Crash Avoidance Metrics Partners (CAMP LLC), has released a comprehensive guidance aimed at infrastructure owners and operators for the deployment of Vehicle-to-Everything (V2X) technology, specifically focused on C-V2X direct communication at 5.9 GHz in the United States (US).

The guidance, developed by 5GAA, benefitted from essential input from ITS (Intelligent Transport Systems) ecosystems stakeholders and partners, including the Utah Department of Transportation, National Electrical Manufacturers Association (NEMA), OmniAir, ITSA (International Transportation Safety Association) and researchers from the University of Michigan. The document is a valuable reference for "Day One" C-V2X deployment by gathering established requirements and new considerations, and it provides compatible guidance for several Day 1s, ranging from road infrastructure owner-operators seeking early deployment based on waivers, through Day 1 where automakers deploy. The primary target audience includes road Infrastructure Owners and Operators (IOOs), who are pivotal in taking up C-V2X technology for transportation safety and efficiency.

The 5GAA guidance report focuses on C-V2X direct communications and streamlines this complex field into commonly understood profiles, simplifying deployment timelines, and ensuring effective communication between vehicles and infrastructure.

It also provides findings from various guidelines, standards, and deployment projects to offer a straightforward guide for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) connectivity required for Day One Connected Vehicle (CV) applications. In addition, it includes guidance and a profile on the messages that can be sent.

The complementary nature of both modes of communication (C-V2X and V2N) can deliver a richer experience for end-to-end use cases by leveraging both local short-range and cloud-based long-range connectivity.

Key highlights of the report include:

- Clarifying expectations for a swift V2X roadside unit deployment, providing concise and accessible materials for all participants in safe traffic communications.

- Identifying a limited but crucial set of messages, interoperability needs, and performance requirements to expedite deployments, ensuring an orderly and safety-critical message set.

- Providing SAE J3161 communication profiles and parameters, creating a standard set of rules for optimal channel access and message usage.

The report aims to establish V2X communications that support interoperability and data integrity, delivering the necessary performance for various Day One applications. It also offers insights into potential Day Two messages, preparing the V2X community for the next deployment stage.
