Intersection safety is a key V2X application.
Rethinking V2X:
From standalone promise to safety complement Dynamic relationships
Vehicle to everything (V2X) technologies have been studied for more than two decades with the same promise: connecting road users to unlock safe, smart and clean road transport solutions. While direct V2X has been tested in numerous pilots and corridors, the automotive industry has rapidly progressed on in-vehicle sensors as well as mobile network connectivity. On one side, advanced driver assistance systems (ADAS) have increasingly addressed safety- and time-critical situations by mitigating their impact or even avoiding crashes. On the other, cloud connectivity and smartphone apps are widely used to anticipate risks, giving drivers early awareness of dangers along the vehicle route. The 5G Automotive Association’s (5GAA) recent study ‘Dynamic V2X Use Cases’ aimed to evaluate the applicability of cellular V2X (C-V2X) technologies to selected safety use cases beyond basic awareness. The report presents a methodology to examine appropriate inclusion of V2X in different safety use cases, such as intersection approach, collision avoidance, and vulnerable road user (VRU) protection.

For each use case, a model of the dynamic relationships between the various actors was evaluated with agreed values for system parameters (e.g. driver reaction time, transmission latency and GNSS error) applied. The exercise aimed to demonstrate how V2X systems could deliver the information required to support the driver’s (and in one case, ADAS) response sufficiently to meet the use cases’ service objectives. The integration of V2X was modelled as a multi-layered framework, where the communication modes Direct (PC5) and Network (Uu) V2X function in tandem with ADAS and on-board sensing systems to form a comprehensive perception profile. The use cases were selected to address distinct operational conditions and information exchange requirements, and the combined analysis provides an overview of what is expected from early Day 2 services. The soft intersection approach use case investigates a new safe and comfortable way to approach intersections where the traffic light is about to turn red.

potentially inaccurate positioning of the smartphone may render the warning ineffective compared to the ephemeral danger. This means the presence awareness warning may need to be given at such an early stage in the scenario that the driver may not consider the initial information as reliable or valuable. In this case, the user interface may need to filter out some alerts based on user preferences. Finally, the high-speed car-to-car rear-end scenario goes beyond the new test cases involving V2X in the Chinese New Car Assessment Programme (Chinese-NCAP) 2024. 5GAA’s evaluations demonstrate the effectiveness of direct V2X during sudden cutout manoeuvres. The analysis tested various highway speeds and following distances where a leading vehicle unexpectedly changes lanes, revealing a slow vehicle ahead potentially leading to a rear-end collision. The findings confirm that under emergency and non-emergency braking assumptions, the required deceleration distance consistently falls within the direct V2X communication range, ensuring adequate response time and mitigating collision risks within the identified safety zones. The report also presented results of other field tests regarding uncertainties related to smartphone position accuracy, showing variation not only between phones themselves, but also around whether they are hand-held or in a pocket. Smartphones experienced noticeable degradation of location accuracy when in dense urban (e.g. urban canyon) scenarios, compared to suburban or ‘open skies’ conditions. Overall, the study applied a detailed methodology to examine a series of safety-relevant use cases. Further work may be needed to improve smartphone GNSS accuracy if we want to include VRUs in the V2X safety ecosystem. The report concludes that direct and network V2X enable the selected use cases, offering complementary characteristics depending on the application context. Deployments making effective use of one or both radio interfaces together with the use of on-board sensors effectively enable the timely and reliable reaction in safety relevant scenarios, taking into account various technical, operational, and system level aspects.

The use case analysis indicates that received signal phase and timing (SPATs) can reliably help to initiate a comfortable soft braking procedure even before the traffic light turns yellow. This involves a gradual warning, initial braking and eventually a full stop. The combined use of V2X and ADAS sensors during the approach reduces the need for high-quality signal phase information, and would work well even when the signal phase information is delayed or estimated based on statistical observations. The intersection safety use case considered scenarios with trajectory conflicts of an ego-vehicle (60km/h) with a bicycle (25km/h), as well as with another vehicle (60km/h). The egovehicle has the right of way while the cyclist or the other vehicle is ignoring to stop. In the described scenario, the cyclist–vehicle cooperative awareness messages (CAM) are received by the egovehicle so the driver is alerted in time and can react by reducing its speed to prevent a collision. The analysis considered the reliability of message reception and the potential low accuracy of the vehicle–bicycle positioning. The results demonstrate that direct V2X communication can enable timely driver warnings, providing sufficient reaction time for effective braking while maintaining a low false alarm rate. In another VRU presence awareness use case, a pedestrian is crossing a single lane urban road at a random mid-block location. The pedestrian is equipped with a smartphone with an app publishing VRU presence data on a MEC/cloud server. A vehicle approaches at the maximum legal speed and receives the pedestrian data via the mobile network. In this scenario, the driver is made aware of the presence of the VRU ahead and encouraged to reduce the vehicle’s speed as they approach the reported danger, so that the pedestrian can safely cross the lane before the vehicle arrives. The results of the analysis show that typical mobile network delay is not the limiting factor to support VRU presence awareness in urban scenarios, but the

V2X is ready – now it needs adoption
Image: Mkmult/Dreamstime.com
Roads are safer when vehicles, infrastructure and users can exchange information, anticipate risks and coordinate movement.
Qualcomm VP product management Hagai Zyss says V2X is already moving beyond trials, but its full safety and mobility benefits will depend on broader adoption by governments, fleets, automakers and other road users. Next phase of road safety
Vehicle to everything (V2X) has moved beyond the proof-ofconcept stage and is already deployed in multiple countries at intersections and across public-sector fleets to support practical use cases such as emergency vehicle pre-emption, pedestrian safety, transit and freight-signal priority, road weather alerts and snow plough operations. This matters because today’s vehicle safety systems are improving, but they cannot solve what they cannot see. The most dangerous moments often happen outside a vehicle’s direct line of sight – a car approaching an intersection from around a corner, a cyclist hidden by another vehicle, a pedestrian stepping into the road from behind an obstruction, or a snow plough operating in whiteout conditions. By the time a driver or an on-board sensor sees the risk, it may already be too late. V2X can help close that gap by allowing vehicles, infrastructure and road users to share information before a danger is visible, making it a practical next step toward safer, more coordinated roads. The next big step in roadway safety will come from enabling vehicles to see beyond their line-of-sight, and V2X can help add this extra layer of awareness. V2X allows vehicles to communicate with other vehicles, roadside infrastructure and, increasingly, other road users. Instead of waiting for a hazard to appear in front of the vehicle, V2X can help warn that a risk is approaching before it is visible. SEPTEMBER 2026

That is why V2X will be an essential part of the next phase of road safety. It does not replace existing sensors or advanced driver assistance systems (ADAS) that help with driving functions such as emergency braking or lane change assistance. It elevates them by adding a layer of connectivity and collaboration. The challenge has always been adoption. V2X becomes more valuable as more participants join the ecosystem. Infrastructure can create early value, especially at intersections and along major corridors, but the full network effect depends on broader deployment across vehicles, fleets, vulnerable road users and public infrastructure. That is where governments and public agencies can make an immediate difference. They do not need to wait for every automaker to deploy V2X at scale. They can lead by equipping public infrastructure and government fleets with V2X, proving the return on investment and helping create the early ecosystem that broader adoption will require. This is already beginning to happen. In the US, state and local governments are deploying connected vehicle systems to address a range of safety and mobility challenges. In Michigan, connected infrastructure and vehicles are being deployed through a smart intersection initiative designed to improve vehicle and pedestrian safety. In Virginia, transportation officials and industry partners have deployed V2X to support

workzone safety, roadside-worker protection and trafficsignal information services. In Georgia, connected roadside infrastructure and utility vehicles are being used to demonstrate vehicle to infrastructure (V2I) communications that support traffic management and roadway safety. Together, these deployments show how governments can begin creating value through infrastructure and fleet investments while helping lay the foundation for broader adoption. Public infrastructure can help create early value, but vehicle adoption will also require the right market signals. The National Highway Traffic Safety Administration (NHTSA) can incentivise V2X deployment in vehicles by incorporating V2X into the New Car Assessment Program (NCAP). Safety rating programmes globally are putting more emphasis on vulnerable road-user protection, obstructed vehicles and real-time road hazards. Those market signals matter because the biggest inflection point will come when automakers bring V2X into production vehicles. Some countries already have millions of V2X-enabled vehicles, while North America is still waiting for major original equipment manufacturer (OEM) deployment. Once penetration reaches meaningful levels, the value of the network grows quickly because each connected vehicle can share what it sees with others.
Hagai Zyss, Qualcomm
V2X is not a futuristic addon; it is a connective layer that can help road safety move beyond the limits of what sensors can do alone The value extends to day-to-day transportation operations. Connected infrastructure can share traffic-signal information with vehicles, support communication with public utility and maintenance fleets, and help agencies manage workzones and roadside operations more safely. These kinds of applications can create value for transportation agencies and road users while building the infrastructure needed for safety deployments. At its core, V2X is about collaboration. Roads are safer when vehicles, infrastructure and road users can exchange information, anticipate risks and coordinate movement. That communication can help a vehicle make way for an emergency responder, adjust for a workzone, approach an intersection more safely or warn a driver about a hazard that is not yet visible. That is why adoption matters. V2X is not a futuristic add-on; it is a connective layer that can help road safety move beyond the limits of what sensors can do alone. If we are serious about reducing crashes and moving closer to Vision Zero, V2X needs to be part of the solution, and governments, fleets and automakers all have a role in helping it scale.

Beyond vehicle-to-vehicle (V2V ) communication, V2X has an important role to play in protecting vulnerable road users, including pedestrians, cyclists, e-bikes, scooters and motorcycles, the very road users that traditional sensors may struggle to detect in time, especially when they are obstructed or moving through complex urban environments. This is where smart infrastructure becomes especially important. Roadside systems can help bridge the adoption gap by anonymously detecting road users who are not themselves equipped with V2X and sharing that awareness with connected vehicles. That makes the system more inclusive and more useful even before every vehicle, bike or pedestrian device is directly connected.

Connecting intersections: Moving V2X from concept to deployment Econolite, Umovity ITS chief technology officer Hans M. Molin highlights a pivotal moment for transportation.
Image: Econolite
Historically, improving mobility and safety was largely done through adopting increasingly sophisticated new traffic management systems and technologies. Yet one of the most transformative technologies is not a new concept: vehicle to everything (V2X) communications. V2X communications enable vehicles to wirelessly communicate with infrastructure (V2I), vehicles (V2V ), network systems (V2N), and pedestrians (V2P) in real-time. The mobility intelligence and return on investment (ROI) promise is compelling; however, it requires a willingness to integrate an ecosystem of intelligent intersections powered by advanced traffic controllers, open architecture software, traffic sensors, edge computing and network communications. Agencies have already deployed many of these, but often systems are not connected to each other to enable the most valuable cross-pollination of data.
The foundation for connected mobility The success of V2X depends on intersections functioning as connected nodes within the transportation network. Connected intersections enable centralised systems to extract, transform and load (ETL) real-time roadway data, creating a network whereby infrastructure can exchange Signal Phase and Timing (SPaT ), MAP and other connected vehicle messages while accommodating evolving DSRC, C-V2X and SAE J2735 standards. At the intersection, traffic cabinets, traffic signal controllers and their firmware must provide this intelligent foundation. The key here is interoperability – they must support open architecture principles to help facilitate seamless communications between roadway users and infrastructure, communications with the traffic management centre (TMC), sensors and emerging V2X solutions without becoming locked into proprietary systems. Equally important is the role of centralised mobility management software or advanced traffic management system (ATMS), providing agencies with access to the data and derived information needed for securely managing connected vehicles across entire networks.
Hans M. Molin
Enhancing safety through real-time awareness V2X introduces new levels of situational awareness by enabling connected intersections and roadway users to continuously exchange information. When integrated with intelligent controllers, sensors, probe data sources and a centralised, cloudnative ATMS platform capable of ingesting and processing realtime data, agencies gain greater visibility into network operations and even forecast conditions. Connected intersections can also provide roadway users with advance warning about emergencies, queue conditions, wrongway movements, pedestrian activity and other potential hazards. This real-time exchange of information helps reduce uncertainty and improves decision-making for all roadway users.
From concept to proven results
What’s next?
A compelling example is the Innovate Mound project in Macomb County, Michigan, US. The opportunity was to create a corridor capable of supporting connected vehicle technologies, real-time traffic optimisation and multimodal mobility applications. A readily available open-architecture traffic controller platform became a key enabler. Roadside units deployed throughout the corridor broadcast SPaT and MAP messages so connected vehicles can better anticipate and navigate intersections more efficiently. The infrastructure also supports safety applications, including wrong-way detection, queue warnings, weather-responsive operations, emergency vehicle preemption and freight priority. These capabilities demonstrate how V2X can move beyond theoretical concepts to deliver meaningful operational improvements that enhance mobility and safety.
The transportation industry stands at a pivotal moment. Connected vehicles are not a future concept; they are an operational reality. The challenge now is accelerating V2X adoption. Fortunately, the standardised and interoperable hardware and software systems are available and, in many cases, already deployed to help cost-effectively drive the adoption. As projects like Innovate Mound demonstrate, the future of transportation will not simply be about moving vehicles more efficiently. It will be about leveraging available technologies to establish the connected ecosystems where intersections, vehicles, and users communicate seamlessly to improve safety and unlock the full potential of connected mobility. The journey toward that future is already underway and V2X is helping communicate the road ahead.

T2X: A bridge from today’s tolling infrastructure to tomorrow’s connected mobility
Image: STAR Systems International
Vehicle to everything (V2X) is moving from concept to deployment across vehicles, roadside infrastructure, and agency planning. For tolling authorities, this raises a critical question: how can they prepare for connected vehicles without discarding proven gantries, automatic vehicle identification (AVI) systems, radio frequency identification (RFID) readers, antennas, transponders and roadside systems that reliably support revenue today? STAR Systems believes the answer is transition, not replacement. Agencies need a path that protects investments, sustains operations, and bridges to a future where vehicles, infrastructure, accounts and mobility platforms communicate seamlessly. That vision drives STAR’s T2X (transponder to everything) initiative, designed to connect today’s tolling technologies with the evolving V2X ecosystem, including future tolling, road usage charging, traffic operations, and safety applications. The challenge is making that transition without leaving proven systems behind. V2X promises safer roads, smarter infrastructure, seamless transactions, and new digital services. The challenge for agencies is not whether to change, but how to do so responsibly while protecting existing investments. Many roadside systems are proven, operating daily at highway speeds under demanding conditions. A successful transition cannot discard this foundation before replacement technologies are standardised, widely embedded, proven and practical. The realistic path is coexistence: current RFID-based tolling and AVI systems must continue while connected-vehicle capabilities are introduced gradually. That transition can begin with the infrastructure agencies already have in place. Transportation has seen this pattern before. Open-road tolling, electronic collection, managed lanes, automated enforcement and mobile payments required more than new equipment. They demanded confidence, interoperability, continuity and clear value. V2X will be no different. While future vehicles may include embedded capabilities, adoption across the fleet will take time. Aftermarket units may be costly, deployment models may vary, and agencies may face pressure to support multiple technologies. Here is where STAR Systems sees a critical need. The industry does not require a sharp break between ‘old’ tolling and ‘new’ mobility. It needs an approach that allows proven transponder-based systems to participate in a broader vehicle-toinfrastructure environment. In this model, roadside structures, AVI systems, and account-based operations are not stranded assets but become part of the migration strategy.
For agencies, that bridge extends the value of existing investments, phases in new capabilities, supports interoperability, and prepares for applications such as V2X-based tolling, road usage charging, managed-lane operations, safety messaging, workzone alerts, and freight services. That makes a flexible, gradual approach essential. The evolution toward connected vehicles is real but uneven. Some vehicles will be factory-equipped, others aftermarket. Some corridors may deploy V2X roadside units quickly, while others move slowly. Agencies will need flexible, low-risk migration strategies. STAR Systems is building T2X around coexistence, interoperability and practical deployment. The goal is not to force agencies into a single choice but to help them connect what they already own to what is coming next. With deep expertise in RFID readers, antennas, transponders, AVI systems, and tolling environments, STAR brings a practical perspective to V2X. Agencies must maintain revenue, reliability and user confidence while evaluating new technologies. Leadership requires not just describing the future but engineering a workable path to reach it. As standards such as SAE J3217 define V2X-based fee collection and agencies evaluate secure, interoperable deployments, the need for a transition technology becomes clear. Agencies will require solutions that support emerging V2X functions while preserving today’s strengths. Ultimately, the goal is to connect today’s systems with tomorrow’s mobility. For STAR Systems, T2X is more than a product direction. It is a statement about how connected mobility could evolve: responsibly, interoperably and without discarding infrastructure that continues to deliver value. The future of tolling and mobility will not be built by choosing between today’s technology and tomorrow’s possibilities. It will be built by connecting them. STAR Systems intends to lead that transition, helping agencies move toward V2X-enabled services while protecting the investments, operations and trust on which transportation systems depend.
T2X: Bridging systems and vehicles STAR’s T2X concept rests on the simple idea that the transponder can be more than an identifier for toll transactions; it can serve as a bridge between today’s tolling environment and tomorrow’s connected mobility ecosystem. SEPTEMBER 2026

Tattile tech sends clear message on V2X Tattile has evolved from its origins to become a technology provider for increasingly demanding mobility applications. Today, the company combines its expertise in intelligent cameras, laser technologies, artificial intelligence, and software to develop solutions for increasingly connected and automated transportation systems. As artificial intelligence (AI) becomes more important in traffic monitoring, the ability to collect information is only one part of the challenge. The real value lies in processing, combining and making this information available to the systems and applications that need it. This is where Tattile’s Stark software platform plays a central role. Stark provides a secure environment for managing the data generated by intelligent cameras and laser technologies, integrating different sources and transforming sensor outputs into structured information that can be used across a wide range of traffic monitoring and mobility applications. Within the Stark ecosystem, neural algorithms for optical character recognition (OCR), vehicle identification and classification, as well as AI-based analysis, can be integrated and configured according to different requirements. The focus is not simply on detecting vehicles, but on turning every transit into structured and actionable data. AI-based processing takes place directly at the edge, within the camera and laser itself. Neural networks analyse images and extract relevant information, so only the required data needs to be transmitted to management or analytics platforms. This approach can simplify large-scale deployments while providing a continuous flow of structured road-traffic information. That information can provide a detailed picture of each vehicle, including its class and country of registration, direction of travel, brand, colour, model and axle configuration. Laser systems can add accurate information on dimensions and profile. These data sources can support applications ranging from traffic monitoring and congestion analysis to infrastructure planning and safety.
An important next step is making this information available to connected mobility and vehicle to everything (V2X) systems. C-ITS already includes use cases such as emergency vehicle warnings, traffic jam warnings and hazardous-location notifications, where information detected by infrastructure can be communicated to vehicles and other road users. In hybrid scenarios, where not all vehicles on the road are connected, Tattile’s technology can identify the class and characteristics of vehicles transporting dangerous goods under ADR regulations. In sensitive areas such as tunnels, this information could help traffic management centres detect potentially critical vehicles and issue appropriate warnings. The same principle can be applied to emergency vehicles; by identifying a vehicle class and its movement, roadside infrastructure could contribute to V2X messages that alert approaching vehicles to an emergency vehicle in transit, giving them more time to clear its path. Traffic data can also provide a broader picture of road conditions. Vehicle counts, classifications, speeds and movements can be used to identify congestion and queue formation and to provide this information to traffic management systems and connected vehicles. Similarly, roadside sensing can detect a vehicle travelling in the wrong direction, allowing the event to be identified in real time and a warning to be sent to approaching vehicles through connected mobility systems. Automatic number plate recognition (ANPR) is one of the technologies available within this ecosystem, providing automatic vehicle identification. Combined with AI-based analysis and laser sensing, however, the platform can generate much richer information than the plate alone. For Tattile, intelligent traffic monitoring is evolving from detecting vehicles to generating usable data that can be shared across the mobility ecosystem. By combining AI, intelligent cameras, laser technology and the Stark software platform, Tattile provides the information needed for increasingly connected, data-driven, and safety-oriented transportation systems.

The smarter road ahead: What V2X means for traffic management What if your car could see around the corner? Not through better cameras or sharper radar, but through something more powerful: a live conversation between vehicles, roads and the infrastructure that manages them. That’s the promise of vehicle to everything (V2X) technology, and it’s changing transportation management. Today’s traffic network runs on detection: sensors and cameras tell a traffic signal that a car has arrived. Useful, but reactive by design, it only knows what’s happening right now. V2X is changing the question from “What’s here?” to “What’s coming?” That answer plays out at every level: how a driver reacts, how a traffic signal responds, and how a network moves. While V2X can feel futuristic, that shift is already well underway, as agencies and industry partners test what happens when infrastructure and vehicles share real-time information instead of working in silos. That wider view gives drivers and infrastructure more time to anticipate what’s ahead. On-board sensors can’t see through a building, around a blind curve, or past the vehicle three cars ahead, but V2X can. By connecting vehicles with infrastructure and other road users, V2X shares information a windshield can’t capture: a pedestrian stepping toward a crosswalk, a workzone past the bend, congestion building several intersections away, or a signal phase about to change. That extra warning time isn’t a side effect, it’s the whole point. A driver or vehicle that knows what’s ahead can adjust speed, change lanes, or pick a different route before a hazard becomes a problem.
It’s also a shift in scale. Instead of optimising one intersection at a time, agencies can optimise the complete trip, from origin to destination. A connected vehicle might receive a recommended route to catch the next green light, while infrastructure uses approachingvehicle data to fine-tune signal timing. Together, these capabilities reduce guesswork on both sides of the windshield and help keep traffic moving with fewer stops along the way. And those fewer stops matter beyond travel time. Every unnecessary stop costs fuel, idling and emissions. A measurable reduction in idling across a corridor is good for drivers, good for agencies with sustainability targets, and good for the air everyone’s breathing. Better information plays a role here, too. When a vehicle knows about a slowdown or hazard farther along its route, it can make a smarter decision earlier, smoothing out the trip instead of reacting to it stop by stop. Optimisation and sustainability don’t represent separate goals. They’re the same objective, seen from two different perspectives.
V2X is changing the question from ‘What’s here?’ to ‘What’s coming?’ Making connections No single piece of technology can achieve this connected vision alone. V2X isn’t pushing agencies to rip out what works; detection, signal controllers and existing traffic management platforms are critical to V2X infrastructure. The opportunity is connecting them, letting vehicles and infrastructure create a shared understanding of the road ahead. With V2X, a warning reaches a driver before a hazard is visible, a signal responds to demand before a back-up, and a vehicle adjusts its route with fewer stops. Getting there will require agencies, technology providers and automakers working to the same goal. But the direction is clear: transportation systems that don’t just detect what’s happening, but anticipate what’s next.
From reacting to anticipating The same data that helps a driver see farther can help a signal think farther ahead. Traditional detection tells an intersection a car is there. V2X tells it where connected vehicles are coming from, where they’re headed, and how traffic is moving across the entire network. That’s the foundation for virtual detection and adaptive signal control: systems that adjust signal timing based on approaching demand, before a queue ever forms. That is a meaningful edge for agencies balancing growth against limited capacity. SEPTEMBER 2026

Ettifos starts next stage technology journey
When vehicle to everything (V2X) moves from a promising technology to part of everyday transportation, the challenge goes well beyond connectivity. Moving V2X from development to real-world deployment requires expertise across the technology stack – from vehicle and roadside hardware to communications, standards and software integration. It also requires an understanding of how those technologies perform in real transportation environments, and how they can evolve as the industry changes. This is the expertise Ettifos has been building since its foundation in 2018. Rather than approaching V2X as an extension of another business, Ettifos has developed around the technology itself. Over the past eight years, the South Korean company has worked across the full V2X stack, developing on-board units, roadside units, communications platforms and software spanning 5G-V2X, LTE-V2X and DSRC. Crucially, that work has extended beyond development. Ettifos has deployed its V2X technologies across real-world projects in Korea, including a C-ITS deployment for Korea Expressway Corporation covering more than 800km of highways. This included connected vehicle equipment, 29 V2X applications and a smartphone-based HMI, giving the company practical experience of deploying V2X across extensive road networks. That combination of engineering and deployment experience now underpins the company’s international expansion, with the US as the next major step. Ettifos is already applying this experience through its participation in the Maricopa County Connected Vehicle Acceleration Zone (CVAZ) project. Supported by a $US20 million co-operative agreement with the United States Department of Transportation (USDoT ), the 2024–28 programme is deploying connected vehicle technology across key corridors, with applications spanning emergency vehicle pre-emption, freight and transit signal priority, and vulnerable road user (VRU) safety. Ettifos is supporting the programme with V2X-AIR, its compact aftermarket V2X device (AVD), which provides C-V2X connectivity to public fleets for signal pre-emption and priority services. The role of V2X-AIR reflects a broader challenge facing the US as V2X moves towards wider deployment. USDoT is calling for widespread, interoperable V2X deployment across the SEPTEMBER 2026

country, supported by federal investment to accelerate adoption. Achieving that scale will require more than equipping new vehicles with V2X; it will also mean finding practical ways to connect legacy vehicles. V2X-AIR was developed around this challenge, bringing existing vehicles into the connected ecosystem and providing fleets and public-sector programmes with a route to expand V2X coverage without waiting for new vehicle implementations. For the US market, technical capability must also be matched with compliance and interoperability. V2X-AIR achieved Build America, Buy America (BABA) compliance in 2025 and Ettifos has received OmniAir Certification for all its C-V2X devices, demonstrating its ability to support federally-funded transportation programmes. But Ettifos’ focus extends beyond adapting existing technology for a new market. The company is also developing technologies needed to support the evolution of V2X. One focus is C-V2X chipset development through ESAC (Ettifos SIRIUS Accelerator Chipset). The aim is to provide a software-upgradable foundation for V2X infrastructure, allowing communications capabilities to evolve as standards, applications and requirements change. This is relevant to vehicles and roadside infrastructure, which can remain in service for many years while the technology around it continues to develop. Upgradeable architecture allows deployed hardware to support new capabilities without requiring replacement as V2X standards advance. The approach reflects a broader aspect of Ettifos’ engineering expertise: developing technology across multiple layers gives the company greater control over how systems perform today and how they can adapt tomorrow. As V2X moves from pilot projects towards permanent connected transportation systems, the next phase will require technology that can integrate with existing networks and operate at scale as standards and applications evolve. Ettifos is taking the experience built through years of V2X development and deployment globally, while continuing to develop the underlying communications technology for what comes next. Its expansion is more than geographic growth. It represents the next stage of a technology journey built around V2X, from engineering and real-world deployment to systems that evolve with the industry.

with traffic signal controllers, transportation networks and back-office systems to enable connected intersection functionality. Applications can include signal phase and timing dissemination, traveller information messaging, emergency vehicle priority, and other connected transportation services that improve safety and traffic flow. Complementing the roadside infrastructure is the on-board unit (OBU) platform, which enables vehicles and infrastructure to communicate in real-time. Together, roadside and vehicle-based communications create opportunities to reduce congestion, support vulnerable road users, improve situational awareness, and enhance overall transportation efficiency.
Vehicle to everything (V2X) technology has moved beyond research projects and pilot deployments. Today, transportation agencies, municipalities and system integrators are increasingly focused on how to deploy connected vehicle infrastructure at scale to improve safety, mobility and operational efficiency. As the market evolves, agencies are looking for more than innovative technology. They are looking for long-term partners with proven engineering expertise, deployment experience, strong customer support and the financial stability to support infrastructure investments for decades to come. That is where DENSO’s smart mobility brand MobiQ® brings a unique advantage. MobiQ was created to bring DENSO’s decades of automotive connectivity and intelligent transportation expertise to the broader smart mobility marketplace. The brand delivers the same engineering quality and reliability trusted by global automotive manufacturers through a growing portfolio of V2X solutions designed for roadside and vehicle deployment. DENSO is one of the world’s largest mobility technology companies, a Fortune Global 500 organisation, and the second-largest automotive supplier globally.

Just as importantly, DENSO helped lay the foundation for today’s connected vehicle ecosystem through its participation in the development, testing and advancement of V2X technologies and industry standards while supporting numerous public and private sector deployments.
Deployment readiness matters Many agencies have learned that successful V2X deployments require much more than compliant hardware. System integration, interoperability, cybersecurity, standards alignment, field support and lifecycle management all play critical roles in achieving long-term project success. As agencies move from pilot programmes toward broader deployments, selecting technology providers with proven implementation experience becomes increasingly important. MobiQ benefits from DENSO’s extensive background in concept development, system engineering, hardware and software development, integration, testing, validation and production-scale manufacturing.
