• The 5GAA Day One Deployment Guide was instrumental in enabling the largest C-V2X deployment during the “Day One Deployment District” in Atlanta.
• 5GAA members demonstrated real-world C-V2X applications showing immediate public value and nationwide scalability.

ATLANTA, U.S. – 3 September 2025 — The U.S. connected vehicle ecosystem took a major step forward as Atlanta became home to the nation’s first “Day One Deployment District” for Cellular Vehicle-to-Everything (C-V2X) technology. The 5GAA Vehicle-to-Infrastructure Communications Day One Deployment Guide was instrumental as a benchmark for C-V2X roadside infrastructure installations such as those earning the spotlight at the ITS World Congress 2025 for the Georgia Department of Transportation (GDOT) and the permanent enhancements for the downtown district.

5GAA members played a key role in showcasing ready-now applications for C-V2X technology in a live urban traffic environment and the clear potential for deployment in other states and cities.

This milestone comes at a moment when vulnerable road user traffic fatalities remain near the highest levels ever recorded, and with traffic congestion costing the U.S. economy more than $36 billion[1] annually. With an estimated nationwide deployment cost of $6.5 billion, as estimated in the ITS America National V2X Deployment Plan, C-V2X offers a powerful solution to enhance road safety.

“Day One Deployment District” also builds a bridge for establishing the C-V2X ecosystem in Atlanta, as OEMs progress from pilot projects toward production-ready architectures. Live demonstrations by 5GAA members and other industry leaders illustrated how C-V2X can offer immediate public value through:

• Faster emergency response with traffic signal preemption and real-time alerts
• Enhancing safety for vulnerable road users
• Lower local agency expenses, reducing costs for school buses and public fleets
• Streamlining tolling and parking through seamless digital transactions

John F. Kwant, Executive Director Americas, 5GAA, said, “Atlanta’s Day One Deployment District proves that C-V2X is ready for prime time. As the global cross-industry association for connected vehicle technologies, 5GAA has worked with its members, public agencies, and technology leaders to turn C-V2X deployment guides into reality. This milestone shows what’s possible when we align standards, infrastructure, and industry commitment”.

With the “Day One Deployment District” anchoring C-V2X in Atlanta, opportunities will also emerge for streamlined revenue streams for local agencies and toll operators. The deployment confirms the State of Georgia’s position as a champion of connected-transportation innovation.

[1] The Economic and Societal Impact of Motor Vehicle Crashes, 2019 (Revised): https://crashstats.nhtsa.dot.gov/Api/Public/ViewPublication/813403.pdf

Connected and Automated Vehicles are expected to make critical decisions based on data from external sources, yet current approaches to security and safety do not address a fundamental question: How much can the content of this data be trusted?

This White Paper tackles this largely unsolved problem by introducing a dynamic trust assessment framework centred on Actual Trustworthiness Level and Required Trustworthiness Level – metrics that quantify the residual uncertainty about whether external data or system behavior can be trusted based on available evidence and how much trust is needed to meet the operational and safety requirements of the current context. This methodology is intentionally designed to be generic, allowing for different implementations that adapt to evolving operational and organizational contexts. A detailed Automated Emergency Braking use case illustrates how the methodology can be instantiated in a real-world scenario.

The Paper concludes by identifying open standardization gaps and proposing directions for future harmonization of trust assessment in cooperative and connected mobility ecosystems.

The 5G Automotive Association is organising the online session “Securing North American V2X Deployments: Introducing the 5GAA SCMS Certificate Policy”.

• Date & Time:  Tuesday, 9 September 2025
• Location: 8:00 am PT / 11:00 am EDT / 5:00 pm CEST

As connected vehicle and smart transportation deployments begin to take shape across the US and Canada, trust and security in C-V2X communications are becoming foundational to enabling a wide range of applications.

Experts from 5GAA, BMW Group, Qualcomm, and Microsec V2X PKI Inc. are joining this online session to present:

• How C-V2X communications can enhance road safety, support connected and automated mobility, and enable future transportation services, including the critical role of security in ensuring these capabilities function.
• The technical architecture and operational model of SCMS Certificate Policy, and how the policy enables secure V2I message exchange across public and private deployments, facilitates cross-OEM interoperability, and fosters a competitive ecosystem of SCMS providers and vehicle platforms.

Agenda

• Opening Remarks: BMW Perspective on V2X Momentum and Security Foundations (Joachim Göthel)
• Technical Deep Dive: SCMS Certificate Policy, Interoperability and Ecosystem Enablement (William Whyte & Peter Lorinczy)
• Q&A

Motivations for C-V2X include augmenting automated vehicles with non-line-of-sight awareness and cooperative intention sharing, supporting V2X-based tolling over the 5.9 GHz ITS spectrum, enhancing road safety and protection of vulnerable road users (VRUs), and improving traffic efficiency. V2X messages—such as Basic Safety Messages (BSMs), Signal Phase and Timing (SPaT), and Cooperative Perception Messages (CPMs)—require robust security to ensure message integrity and authenticity.

These messages unlock a variety of use cases that depend on trusted and anonymous communications between vehicles, infrastructure, and other road users.

To support these needs, 5GAA has released its SCMS Certificate Policy, a set of rules tailored to the North American ecosystem. Developed by 5GAA Working Group 7 on Cybersecurity, the policy reflects input from automakers, suppliers, semiconductor leaders, PKI providers, telecom infrastructure vendors, and broader industry stakeholders—including feedback from transportation agencies and industry organisations.

Whether you are a policymaker, technology developer, or part of the transportation ecosystem, this is your opportunity to connect with these industry leaders and better understand the security foundations of North American C-V2X deployments.

Thank you, Huawei, for supporting the 35th 5GAA Meeting Week.

In a global premiere in May 2025, the 5G Automotive Association (5GAA) demonstrated connected vehicles using non-terrestrial networks (NTN) complementing terrestrial 4G and 5G networks for emergency messaging. It also did the first on-the-road, live-traffic demonstration of 5G-V2X Direct technology capabilities for advanced connected-vehicle services and ready-to-deploy vehicle-to-network (V2N) technologies, which can improve road safety in real traffic conditions.

Missed the demos? No problem! Now you can see the replay of these advanced vehicle technologies! Watch the full video below to experience the demos in action!  

5GAA-member vehicle manufacturers BMW Group and Stellantis and technology partners Anritsu, Cubic³, Deutsche Telekom, HARMAN, Jember, LG Electronics, Qualcomm Technologies, MediaTek, Rohde & Schwarz, Rolling Wireless, Skylo, VEDECOM Institute, and Viasat participated in the NTN satellite connectivity demonstrations. The demos focused on realising hazard warning and emergency messaging use cases in the vehicle as well as illustrating how NTN will complement terrestrial 4G and 5G networks in the future.

Demonstrations on public roads underlined how NTN can support ubiquitous automotive connectivity for connected services with seamless integration and switching between NTN and terrestrial networks to enable voice communication. In the future, car drivers may not even realise that satellite connectivity has replaced a terrestrial network. According to the 5GAA 2030 Roadmap, the initial market deployment of satellite connectivity in vehicles is expected by 2027 (based on IoT NTN 3GPP Release 17).

Anritsu, Keysight Technologies, Rohde & Schwarz, and MediaTek complemented the NTN demonstrations with parallel test equipment measurements for performance verification.

For the first time on public roads, 5GAA member Valeo, in collaboration with Marben, demonstrated 5G-V2X Direct, in which two vehicles shared sensor data, triggering a warning of a pedestrian crossing at an obstructed intersection. This demonstration illustrated how 5G-V2X Direct (based on 3GPP Release 16) will enable vulnerable road users’ advanced protection by leveraging sensors and camera feeds from other vehicles to alert drivers, paving the way for smarter mobility. As per the 5GAA Visionary 2030 Roadmap, 5G-V2X is expected to be mass-deployed in commercial vehicle models starting from the time horizon 2026-2029.

The public road demonstrations continued with V2N technology for road users’ protection. 5GAA members, including Nokia, Orange, Stellantis, Valeo, and VEDECOM Institute, showcased interoperable V2X Platforms with vehicles, mobile applications and smart intersections (equipped with cameras and connected via the 5G networks) sharing collective perception to enhance road users’ safety.

 Additionally, HARMAN and u-blox showcased Emergency Electronic Brake Light (EEBL) near-real-time alerts to prevent hard braking events in line with the upcoming 2026 Euro NCAP local hazard warning requirements, and used precise positioning techniques to prevent false alerts.

5GAA members Rohde & Schwarz, S.E.A., Keysight and Orange also exhibited Next Generation Emergency Call (NG eCall) verification and network performance.

The event, hosted by Telecom-Paris, highlighted how 5GAA is driving the development of new standards for safety and innovation in automotive connectivity in Europe and globally.

Currently, for V2X direct communication, there is no available common policy (certificate policy for Public Key Infrastructure, or PKI, operators) for Security Credential Management System (SCMS) in the U.S. or Canada. A few SCMS providers created their own policies, which are not only incomplete but there are no published common policy documents feasible for SCMS PKI operation, hindering the widespread adoption of the technology. The Government of Canada sponsored an effort which resulted in a model for consideration.

A common Certificate Policy (CP) would help facilitate an ecosystem supporting interoperability and shared trust for V2X direct communication. The European Union addresses this issue by taking a central regulatory role, creating the CP, Security Policy (SP) and C-ITS Point of Contact (CPOC) documents that govern a V2X PKI for direct communication. North America need not duplicate what has been done elsewhere, though an accepted policy will build a greater ecosystem and support V2X direct deployment among a diverse set of automakers and other transport agencies.

The Certificate Policy Proposal contributing to this Work Item (WI) evolved into a Technical Report (TR) that develops a clear CP leveraging global best practices for security PKI and practical experience securing V2X direct communication, as well as common processes to facilitate an approach to SCMS.

For V2X mobile network communication, certificates are needed to authenticate interconnected backend systems and to protect communication between the systems. This Technical Report also elaborates on how to handle those certificates.
