This updated document series from the 5G Automotive Association (5GAA) provides a comprehensive framework for defining and analysing C-V2X use cases and their associated Service Level Requirements (SLRs). It builds upon previous work, refining methodologies for describing use case scenarios, considering factors like road environments and involved actors.

Published in three volumes, each of them includes a curated set of C-V2X use cases, respectively detailed with specific SLRs. These use cases serve as a valuable resource for 5GAA work groups, guiding the development of C-V2X solutions, informing standardisation efforts, and supporting the creation of robust business cases for deployment.

Intersections are a hotspot for traffic fatalities and injuries globally, with nearly a quarter of U.S. traffic fatalities and half of all injuries occurring in these high-risk areas. To address this, the 5GAA has developed a technical report on the ‘InterSafe Service,’ an approach leveraging infrastructure sensor-sharing to increase intersection safety for all road users, especially Vulnerable Road Users (VRUs) like pedestrians and cyclists.

This report explores key use cases, system requirements, and deployment options for integrating Vehicle-to-Everything (V2X) communication technologies with infrastructure sensors. It outlines a framework for developing interoperable, standardised solutions that can operate efficiently within existing Intelligent Transportation System (ITS) spectrums. Crucially, the service is designed to deliver safety benefits even during the early stages of V2X adoption, when only a fraction of vehicles are equipped with these technologies.

The document also provides recommendations for global standards organisations, such as SAE International and ETSI, to expedite the development of system-level profiles. By fostering collaboration across stakeholders, the InterSafe Service has the potential to significantly reduce intersection-related incidents and accelerate the adoption of life-saving technologies worldwide.

5GAA welcomes the renewed attention and subsequent discussions on Next Generation eCall (NG eCall) and the legacy fleet, following the second phase of the IDIADA study, presented on 12 December 2023. Whilst the opportunity to address the critical issue of the legacy fleet is welcome, we wish to draw attention to some key industry concerns.

In this position paper, we underline that industry cannot be held liable for the lack of service continuity of 112-based eCall for the legacy fleet, which result from obsolete legislative requirements. Since both retrofit as well as the extension of 2G/3G networks are implausible, we call for public authorities to take responsibility in informing users in the event of eCall failure, in instances outside industry control. We also encourage further research to be carried out to revise the current eCall regulatory framework so that it becomes future proof and does not lead to the same situation in the future as we have now once NG eCall becomes obsolete, or 4G networks are being transitioned to other technologies. This should be based on a transparent dialogue between authorities and industry to find the right solution.

Sustainability benefits of C-V2X

Cellular Vehicle-to-Everything, or C-V2X, communications will make transportation not only safer and smarter but also more sustainable.

Sustainability has three dimensions: environmental, social and economic.

C-V2X ticks all three boxes:

• Environmental: By helping to make every trip smarter, safer and more efficient, C-V2X helps reduce congestion and accidents, thereby reducing air pollution, noise pollution and energy use.
  
• Social: Saving lives and avoiding injuries are clear social benefits. By enabling real-time communication between pedestrians, cyclists, traffic infrastructure and moving vehicles, including motorcycles and electric scooters, C-V2X will help avoid accidents that otherwise would result in injuries and deaths.
  
• Economic: By enabling more efficient mobility, C-V2X will save people and employers billions of man-hours currently wasted in traffic jams. Those man-hours can then be dedicated to more rewarding activities.  

C-V2X also enables the growth of autonomous mobility, which in turn offers even greater sustainability benefits, for example mobility-as-a-service offerings.

Could you tell us briefly about Verizon’s involvement in 5GAA and how your company benefits from being a member?

Verizon has been an active member of 5GAA since its inception. We started out as a general member and initially contributed at the working group level. We saw tremendous value in taking a leadership role in 5GAA as a major U.S. telecommunications provider and were elected by the members as a gold board member in 2021. Currently, Verizon is a platinum board member of 5GAA and we are playing a critical strategic role as one of the key stakeholders in the V2X ecosystem. 

When did you first become part of the 5GAA board? What are some of your responsibilities, and what has been your most rewarding experience so far?

I represent Verizon on the 5GAA board as an alternate board member since 2021. In my role as a board member I have the privilege and responsibility to ensure 5GAA remains focused on key strategic focus areas which will accelerate a large-scale deployment of Vehicle-to-Everything (V2X) across the globe. My most rewarding experience has been to collaborate with other 5GAA members who are leaders from auto OEM customers, their tier 1 suppliers, chipset and module providers and other ecosystem partners. This technical collaboration between all the stakeholders is the key to drive innovation and unlock the full potential of V2X communications at scale and make it a reality.

Can you share any recent examples of how Verizon has collaborated with other 5GAA members to drive innovation in the industry?

Verizon has taken a leadership role in bringing the V2X ecosystem partners together under the 5GAA umbrella. We have demonstrated thought leadership in defining the network architecture to solve challenging V2X requirements leveraging key technology enablers such as 5G, multi-access edge computing (MEC) and Hyper Precise Location. Our recent V2X VRU (Vulnerable Road User) demo in Detroit showcasing interoperability between different network operators and application providers generated a very positive response and engagement from auto OEMs, Departments of Transportation and road operators. The demo was successful due to close collaboration with several 5GAA member companies.

As the lead of the VRU DEMO Work Item, could you elaborate on the significance of demonstrating interoperability in the context of Vulnerable Road User protection solutions?

VRU DEMO is one of the key strategic focus areas at the 5GAA board level that the industry has been trying to address for many decades. We believe the C-V2X and other technology enablers (5G, MEC, Hyper Precise Location) are ready to mitigate the number of road accidents involving vulnerable road users such as pedestrians and cyclists. In order to deploy such a VRU solution at scale it needs to work across multiple operators, multiple auto OEMs, multiple application providers and multiple cloud providers. We reached a significant milestone by demonstrating interoperability amongst different stakeholders and showcased the technology is ready to deploy at scale with existing networks. The learnings from the demo are being replicated in other parts of the world and are informing U.S. DOT V2X Deployment plans.

What criteria were used to select the specific use cases for demonstration in VRU DEMO? How did these use cases represent real-world scenarios and challenges?

There has been extensive discussion within 5GAA to define different VRU scenarios. Different flavors of VRU use cases have been documented in published technical reports. The demo team carefully selected most common real world VRU scenarios such as active pedestrian crossing alert and using roadside cameras and artificial intelligence, machine learning logic in the MEC to detect pedestrians and alert the drivers to avoid potential collision. 

Verizon participated in the demos with a showcase of its network solution using multi-access edge computing. How does MEC differ from traditional network-based computing in terms of its benefits for VRU protection applications? 

MEC allows us to bring traditional cloud compute and storage within the mobile network closer to the edge where the data is generated reducing the end to end latency. It is well established that MEC is a key differentiator and technology enabler for latency critical use cases such as VRU protection. Verizon has already deployed public MEC across the United States in partnership with cloud providers. We continue to drive innovation by developing standard MEC and Network APIs for application providers. During the VRU demo we demonstrated near real time VRU alerts over 5G and applications hosted on Verizon’s Detroit MEC. 

The 5G Automotive Association (5GAA) thrives on the collective expertise and collaborative spirit of its members. Over 110 organisations strong, our membership represents a global network of market leaders and innovators shaping the future of connected mobility.

We are kicking off a new series, “Meet Our Members,” to delve deeper into the stories of the individuals who make up the backbone of 5GAA. First up, we will be featuring Menno Malta, CEO of Monotch, who has been actively involved in one of 5GAA’s most recent and exciting areas of work – Vehicle-to-Network-to-Everything (V2N2X) communication.

This interview series will showcase a diverse range of profiles, highlighting their contributions, challenges, and predictions for the exciting world of 5G-connected transportation. Get ready to be inspired by the passion and ingenuity of our members as we meet the people who make 5GAA.

Menno, you are the CEO of Monotch, a 5GAA member company. How does Monotch’s work relate to 5GAA’s, and what keeps you engaged with our association?

Monotch operates at the forefront of the V2N2X market. Our proven TLEX platform is used by cities and road authorities all over the world to connect mobility and digital infrastructure bringing substantial societal benefits and increased cost-effectiveness.

The initial interest that drew us to 5GAA was the opportunity to engage with OEMs, mobile network operators, and related industries. This is still of interest! We really appreciate the possibilities to discuss developments and work jointly on progressing the market. The networking opportunities are also great for us.

Monotch is based in the Netherlands. Last year, your views were instrumental in the organisation of 5GAA’s workshop in the Hague, where we looked at C-V2X deployment in the Low Countries. Two years later, what is the state of play for C-V2X and connected mobility in the Netherlands, and how do you see it unfolding?

In the Netherlands, we see a steady growth of smart and connected roadside infrastructure as well as new use cases such as emergency vehicle warnings that are now available on a large scale. This leads to more connected parties, including the first vehicle OEMs. On top of this, there is a push on urban challenges and use cases, which will lead to even more data and impact in the next few years. The Netherlands is truly a lighthouse deployment, and authorities from other countries come here often to see what’s happening and how they can apply learnings in their own jurisdiction.

One of 5GAA’s recent areas of work has been vehicle-to-network-to-everything (V2N2X) communications, and you’ve been one of its main contributors. What is V2N2X, what makes this such an important topic, and what are some of the biggest hurdles to overcome in achieving its widespread adoption?

V2N2X is a subset of overall V2X, where the cellular network and cloud components are used to realise connected mobility. It allows the ecosystem to get to scale with many use cases in a relatively short term, as it leverages existing technology such as apps, onboard units and, of course, the 4G/5G network! I think it’s hugely important for 5GAA as it shows the value of a connected ecosystem to the main stakeholders and can kickstart overall C-V2X deployment.

The V2N2X work item has been concluded with the publication of a white paper, ‘Road Traffic Operation in a Digital Age,’ and two associated reports. What is the objective of these publications, and how do they complement each other?

The white paper can be seen as a summary of the Technical V2N2X Architecture report. It’s a great read for everyone involved in this market, whether you’re an authority or a private sector executive. The Technical V2N2X Architecture report offers detailed insights into the blueprint architecture, and I recommend it to subject matter experts.

The other technical report is of a different nature. It describes the V2N2X market from a business perspective—for example, the market size, the kinds of business models we see, and which factors drive the market. It also contains descriptions of large-scale example deployments, taking away whatever doubts people might have about the feasibility of V2N2X..

The upcoming online session on 18 June will present the findings of these publications. What are you most excited about sharing with the audience?

So much to share! I can promise the session will be packed with insights, but I’m probably most excited to share the OEM and IOO (Infrastructure Owner and Operator) customer profiles we created. It’s about their goals, pains and gains, and for this, we did a survey and an  analysis of large-scale deployments. I’m so excited about it because it really ties to the why of our work.

WASHINGTON D.C., March 7, 2024 – Our organizations, representing the full breadth of the U.S. transportation stakeholder community, fully share the Biden Administration’s commitment to ensuring that connected vehicle technologies operate in a way that is safe and secure, and which protects users’ privacy. We applaud the Department of Commerce and Bureau of Industry and Security for recognizing the many benefits of connected vehicles and noting that its recent Advanced Notice of Proposed Rulemaking does not intend to imply that lifesaving technologies such as vehicle-to-everything (V2X) communications are unsafe for use in the United States. According to the latest estimates from the National Highway Traffic Safety Administration, 42,795 people died in motor vehicle traffic crashes in 2022. We continue to face a national crisis of traffic deaths on U.S. roadways, and we firmly believe that V2X technologies, which allow communication between vehicles, infrastructure, and other road users including pedestrians and bicyclists, can dramatically reduce crashes and resulting fatalities. V2X technology can also help advance climate and sustainability goals by increasing traffic flow and efficiency. We reaffirm our continued support for the rapid, widespread deployment of V2X technologies.

We note that all V2X systems have been designed from the outset with privacy and security in mind, and that V2X has been deployed for a wide variety of use cases in states across the country without incident. Our members have worked closely with U.S. Department of Transportation (USDOT) for several years to proactively develop a robust message security solution for V2X communications. This collaboration has produced a security system that ensures V2X safety messages contain no personal or equipment-identifying information and that utilizes encryption and certificate management methods to limit data collection and prevent unauthorized vehicle manipulation. Privacy and security are also key pillars of our members’ ongoing collaboration with USDOT on the development of a National V2X Deployment Plan. We also note that the supply chain for connected vehicle technology, including V2X direct, is mature, geographically diverse, and not dependent on any particular region or country.

The United States is currently a leader in V2X innovation, but risks falling behind if the government hampers broadscale deployment. We urge the Department of Commerce to work closely with transportation stakeholders to ensure that any resulting regulations that address national security risks are narrowly tailored to minimize unintended consequences or significantly disrupt industry efforts to deploy lifesaving safety technologies.

We look forward to working collaboratively with all stakeholders on this matter to ensure the safe and effective deployment of V2X technologies.
