The international collaboration of tech leaders and public sector on a live connected car trial will pilot new roaming technology for traffic safety on 2 December 2021.

2 DECEMBER 2021, Turin (ITALY) – On 2 December, the City of Turin (Italy) will host a live trial of new driver and pedestrian safety technology allowing near-real-time notification of roadway hazards through 5G-Edge networks. This trial is one of a series conducted internationally by a historic public-private collaboration over the next few years, organized by the 5G Automotive Association (5GAA) and eight member companies representing leading technology companies from around the globe.

“This collaboration between the 5G Automotive Association and its member companies is the perfect example of how we can secure safety on roads and build the future of connected mobility,” said Maxime Flament, CTO of 5GAA. “This time, demonstrated use-cases take place in Europe through 5G and Edge networks—I look forward to seeing more in the future in the United States and other continents.”

The promise of 5G and Edge technology has long been anticipated to deliver new connected services that will revolutionize daily life, with the estimated new economic opportunity stretching into the trillions USD over the next 10-years_1. The global connected car market size alone is projected to reach USD 191.83 billion by 2028.

5G transmission speeds and so-called “Edge” servers—locally installed, high-powered computers capable of running Artificial Intelligence programs—open the door to smart city technologies like near real-time traffic management and innumerable other business applications. The connected car concept uses this high-speed and Edge computing technology to communicate with car sensors and pedestrian smartphones, via a user-authorized mobile app—about traffic hazards, like accidents and road construction—to Pedestrian and in-vehicle driver safety and efficient navigation.

“The connected car concept is an important validation of the combined value of Edge, of 5G and IOT,” said Paolo Campoli, Head of Global Service Provider sector at Cisco, “We are so excited to take part in this event that creates a platform for innovation in 5G IOT. The integration of 5G mobility, applications and data processing at the Edge requires expertise from very different domains—expertise that Cisco and Partners can bring. It includes elements of automation, intelligent infrastructure and workloads control, cybersecurity protection and end-to-end application observability. The live trial in Turin is a great opportunity to show how the intersection of Edge, 5G and IOT based on Standards creates a platform to connect Service Providers and Industries.”

This live international trial attempts to solve one of the more technical challenges of making the connected car concept a daily reality. The 5G networks underpinning the concept are managed by communication service providers (CoSPs) according to geography, each with different edge solutions that must be able to communicate without interruption of the V2X applications as drivers cross borders. Roaming services—the ability to make a call regardless of the network—is one early success of multi-mobile network operators (MNO). Demonstrating the connected car concept can work in a roaming scenario is the core objective of the live trial and represents the first of any such attempt in Europe.

“Telecom operators will have to play a major role by enabling applications and services for the connected car ecosystem,” says Shamik Mishra, CTO Connectivity, Capgemini Engineering. He further adds: “Capgemini is excited to bring its innovative federated MEC (Multi-Access Edge Computing) platform and applications to this 5GAA trial to demonstrate the true value of intelligent industry, leveraging data in the vehicles and edge-cloud. The trials serve as a stepping-stone for realizing the potential for automakers to provide services to their connected cars from the network”. The trial will demonstrate how the car manufacturers, MNOs and technology providers come together to help overcome the challenge of when a vehicle moves from one network boundary to another or Inter-MNO handover of MEC service.

The Turin live trial addresses three objectives:

• Objective 1: Multi-MNO scenario: How can a vehicle, which has radio access to MNO A, use a MEC application, which is operated by MNO B -> Interworking between MNO‘s (by NOT losing the benefits of low latency)
• Objective 2: Global operational Availability: How can an OEM as the MEC application developer be sure, especially on a global basis, that a MEC application works in the same way if it’s operated by MNO A, or if it’s operated by MNO B
• Objective 3: Multi-MNO with roaming scenario: Where the two operators can seamlessly transfer the V2X service from one operator to the other as the car OEM moves from one geo to the other in a roaming scenario. Typically, when an in-vehicle driver does a cross-border travel that involves two operators.

One of the key benefits of the trial is the value demonstrated by bringing in a large ecosystem to help develop not only the technology but also build the business case and model that will help drive the market adoption for 5G and C-V2X to help into the digital transformation of smart cities of the future. To succeed in this endeavor, it will need a village and investment from both public and private sectors to help adopt this new technology to provide a quality of life for all citizens.

The city of Turin is delighted to facilitate the 5GAA Multi Operator MEC Trial with its Smart Road infrastructure and the technical support of 5T. We see – Chiara Foglietta, Deputy Mayor for Mobility, Ecological and Digital transition, Innovation says – C-V2X services as fundamental to develop a sustainable and safe mobility for all the citizens, whatever transport means they use. In the future, Turin wants to continue the collaboration with 5GAA and offer its Smart Road infrastructure for further scale in the live traffic within Torino City Lab and the new project “ Turin House of emerging Technologies – CTE NEXT”

“As TIM, we are honored to be hosting in Turin such a challenging trial by leveraging our Innovation Lab competencies and our pre-commercial instances of Edge Cloud,” says Daniele Franceschini TIM VP Innovation, Standard and Portfolio. “The federation model implemented with our partners enables a ‘continuum’ between Edge Cloud instances allowing players from the automotive industry and beyond to benefit from a seamless cloud experience across country boundaries.”

“Greater connectivity speeds, improved hardware and expanded software expertise have opened new opportunities for Stellantis with safety systems being one of the many areas we focus on,” said Mamatha Chamarthi, Head of Software Business and Product Management. “Through smart and strategic partnerships such as 5GAA, we will capitalize on next-generation systems and prove out the technology.”

The demonstration brings new learnings for various players across the value chain and creates a testbed for trying out new 5G connected car services at the Edge in subsequent phases. The Turin Live Trial will run throughout the day on 2 December 2021.

BACKGROUND

In this live trial, Telecom Italia (TIM), Telefonica, BT/EE will demonstrate the NSA 5G networking capabilities and the Edge Cloud solution to deliver connected car use cases at the Edge of their networks for their customers. TIM makes its Innovation Lab facilities available and its commercial 5G network with pre-commercial Edge Cloud specific features such as Local Break Out, that together with the federation of edge platforms in TIM, BT/EE and Telefonica make the use cases available for roaming users from BT/EE and Telefonica.

The three companies are hosting Capgemini’s ENSCONCE MEC platform, built upon the Intel Smart Edge Open toolkit, the Intel® Distribution of OpenVINO toolkit, and Intel hardware to enable connected car use cases at the Edge on 2^nd Gen Intel Xeon Scalable processor equipped Cisco Servers. Intel Smart Edge Open (formerly known as OpenNESS) is a royalty-free edge computing software toolkit for building optimized and performant edge platforms.

“The international live trial of building and provisioning Connected Car edge services in a multi-operator scenario is a transformative 5G and Edge use case,” said Renu Navale, Vice President and General Manager of Smart Edge Platforms Division at Intel. “This trial demonstrates the possibilities that 5G connectivity and edge computing can bring to connected car solutions, when the broad ecosystem collaborates and uses Intel technologies such as Xeon processors, Smart Edge Open and OpenVINO.”

Capgemini’s ENSCONCE MEC Platform provides multi-tenancy and multi-MNO MEC federation capabilities. The visual compute applications for pedestrian detection and tracking supported by Capgemini’s Orbital Car Situational Awareness V2X platform. To realize the Active and Passive Vulnerable Road User (VRU) use cases, Cisco provides the Edge infrastructure based on CISCO UCS Servers (the Unified Computing Systems that combines computing, network and management in a cohesive architecture) hosting the ESCONCE platform, used to demonstrate Virtual-RSU and host V2X applications that are based on the Intel Xeon Scalable Processors and Intel HDDL-R Visual Accelerators. Harman International and Capgemini provide the Virtual-RSU and RSE solutions respectively to realize various V2X use cases with location-aware and AI inferencing technologies. Harman also offers V2X Application Server and a 5G enabled TCU that integrates seamlessly with Stellantis/FCA car and hosts V2X applications.

“It is key that operators and industry partners collaborate to explore the technical feasibility and benefits to unlock the new business opportunities and services to our customers. In this project, we are jointly evaluating the potential to federate edge cloud compute capabilities across multiple geographies to support low latency use cases, including key connected car use cases being delivered as 5G edge services in a multi-MNO, multi-OEM environment,” said Sunil Joshi, Senior Manager, Global Roaming Products at BT/EE.

“Telecom operators will have a key role in supporting V2X services and this trial demonstrates the value of leveraging mobile architecture, federating edge platforms and allowing local break out in visited network. Such an approach as defined in the GSMA Operator Platform Group allows customers and developers to deploy their applications across multiple operator domains, and our end users to have the best latency and customer experience when accessing their services,” said Juan Carlos Garcia,  Senior Vice-President of technology innovation and ecosystems, Telefonica.

“At Harman, we are focused on building connectivity solutions at the intersection of 5G, V2X and Edge Computing that will build more equity on the road for all users,” said Mahsa Nakhjiri, Director, Product Management. “While these technologies can unlock many new use cases and experiences, the most important element of any solution in this space is safety.  As programs such as this one fueled by the collaboration of industry leaders and organizations like 5GAA bring a new degree of safety to users, they will also lead to a higher level of confidence in autonomous vehicles.”

The present document aims to study the requirements of positioning, build understanding of the positioning system framework, and offer the corresponding technologies according to the requirements and environments, as well as some demonstrations in High-Accuracy Positioning for Vehicle-to-Everything (V2XHAP) services.

With the evolution of V2X services from assisted driving to automated driving, the use case requirements are also changing in terms of the availability of network coverage, level of uncertainty, availability of features for simultaneous localisation and mapping (SLAM)-based positioning techniques, reliability, latency, speed, data rate, communication range, as well as positioning accuracy, which is changing from metre level to sub-metre level. Different from other services, positioning information is one of the essentials to guarantee the safety of Internet of Vehicles (IoV). Some important KPIs for positioning have been described in 3GPP, such as positioning accuracy, latency, update rate, power consumption, etc. Furthermore, there are some specific needs in terms of V2X service scenarios, such as continuity, reliability, and security/privacy, etc. All positioning KPIs for V2X mentioned above need to be clarified, especially positioning accuracy which is the most basic requirement in V2X service.  In some use cases, such as automated driving, remote driving and platooning, centimetre-level positioning with stable performance provides the necessary accuracy and safety assurance.

Road safety is a crucial aspect of mobility both for individuals as well as for policymakers. Road fatalities, in the European Union (EU), for example, have decreased by approximately half between 2001 and 2018 from 54,000 to 25,100 per year. However, in recent years, the number of fatalities has been on a stable level, and additional efforts are needed to further reduce the number of deaths and severe injuries.

5GAA has made VRU protection a priority area and this White Paper therefore aims at shedding light on the safety benefit that selected V2X use cases offer, which can have a significant impact on the protection of the most vulnerable traffic participants. Ultimately, this also has a positive impact on health-sector costs incurred, by reducing the number of people suffering serious injuries with life-changing consequences.

The NESQO Work Item (WI) kicked off in February 2018 with input from car makers, in order to address key automotive requirements on a selected set of identified use cases. The main objective of the study was to provide Predictive QoS for C-V2X in 5G, utilising technologies including End-to-End Network Slicing, Multi-Access Edge Computing (MEC), an evolved QoS framework and Machine Learning.

Upon conclusion of the NESQO WI, the need for a follow-up WI was put forward; some of the topics already identified in the original WID were not fully covered in the NESQO TR and needed further study. Additionally, new requirements had been identified, that were relevant to the agreed scope but not included in NESQO.

This document addresses the 5GAA WG2 Work Item ‘Enhanced End-to-End Network Slicing and Predictive QoS’.

In light of on-going discussions on a legal framework for the European C-ITS deployment, a minimum set of specifications and configurations is needed for existing ITS standards ensuring the interoperability of C-ITS service among ITS stations using different communication technologies and systems, e.g. short-range and long-range radio communications.

While C-V2X standards are already finalised for 3GPP Rel. 14 and 5GAA published White Paper on C-V2X Use Cases: Methodology, Examples and Service Level Requirements, there are still many options on how to configure and establish parameters for C-V2X systems. In order to provide a common standard interpretation, corresponding system profiles are needed, which outline the basic system settings and environments

In Europe, Basic System Profiles (BSPs) have been developed by the Car-2-Car Communication Consortium (C2C-CC) and the EU-funded C-ROADS Platform project, assuming ITS-G5 with IEEE 802.11p as radio access technology for V2V and V2I communication. Though many aspects of the existing BSPs could be reused, there are some modifications needed for C-V2X. In addition, there would be extensions required in order to accommodate alternative communication links like V2P, V2N, and V2C.

5G Automotive Association makes publicly available the following  C-ITS Communication System Profiles:

• Technical Specification C-ITS Communication System Profile Using Cellular Uu Interface
• Initial C-V2X System Profile (ICSP) – Amendments to C2C-CC Basic System Profile
• Initial C-V2X System Profile (ICSP) – Amendments to C-ROADS Roadside System Profile

Turin, 14 November 2019 – Smart mobility technology is a reality today, with ‘Cellular Vehicle-to-Everything’ (C-V2X) allowing connected vehicles to communicate with the cloud, directly with each other and their surroundings. Deployment plans are primarily sustained by the global trend in the automotive industry to adopt 4G LTE cellular technology, followed by the emerging 5G high-speed low latency communications. Beyond infotainment, C-V2X will capitalize on vehicular and smartphone connectivity to contribute to better safety, less congestion and reduced emissions. 

During a live demo event in Turin, the 5G Automotive Association (5GAA) showcased ready to deploy use cases in the streets of the city and a sneak preview of what the future has in store on the renowned Lingotto rooftop test track.  

Prominent members and partners of the 5GAA including Audi, Continental, Ericsson, Fiat Chrysler Automobiles, Harman Samsung, Marelli, Pirelli, Qualcomm, TIM and Vodafone demonstrated the current state of C-V2X and the road to future, Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), and Vehicle-to-Network (V2N) applications based on 4G LTE and 5G. 

“Connected mobility is a market reality.” says 5GAA Chief Technology Officer, Dr. Maxime Flament. “The use cases demonstrated in the streets of Turin are planned for deployment with a huge industry momentum based on the evolution path to 5G capabilities.”  

Using both direct short-range communications and mobile networks, the open-road demonstrations showcased the extensive capabilities of today’s C-V2X technology, ready for deployment. To name a few: 

• Protecting vulnerable road users, for instance, by alerting drivers about a pedestrian at a crossing using LTE-connected infrastructure. 
• Smoothing traffic by allowing public authorities and road operators to provide real-time warnings to drivers in urban environments concerning roadworks or speed limits, via the network. 
• Preventing incidents at dangerous intersections or in the event of unexpected braking, thanks to C-V2X direct-short range communications between vehicles. 

The track demonstrations at Lingotto underlined the enhanced safety benefits that can be expected thanks to the versatility of 5G and the wide range of services it enables. To name a few: 

• Vehicles will geo-tag dangerous areas for the following cars or provide ‘see-through’ functions to avoid dangerous overtaking. 
• Pedestrians will be detected directly via their smartphones and surrounding vehicles will be warned. 
• In case of accidents, emergency services will be able to visualize the situation live using on-board cameras of surrounding vehicles, improving response times and providing emergency responders situational awareness prior to arriving at the crash scene. 

Furthermore, Intel showcased an “In Vehicle Entertainment” demo at the Museum, in collaboration with Marelli, TerraNet and Equinix, showing how Multi-Access Edge Computing (MEC) can support immersive high-definition (HD) entertainment for all occupants of a moving vehicle, including video streaming, gaming, virtual reality (VR), office work, online education, advertisement. 

A short summary on each of the 5GAA C-V2X use cases, demonstrated today in Turin 

Demo 1 “Vulnerable Road Users”: open road demos on safety  

In this trial – which is part of Torino Smart Roads Initiative patronized by the Municipality of Turin – TIM, Links Foundation and Luxoft showed how the communication between the various actors moving along the roads can help in detecting potentially dangerous situations. The goal of the demos was to demonstrate how the 5G mobile network facilitates the protection of Vulnerable Road Users: pedestrians (“Presence of a pedestrian on a crosswalk”) and cyclists (“Presence of a connected bike on the road”). In the case of a pedestrian approaching a crosswalk, a Roadside Unit connected to the mobile network, equipped with a camera able to detect the event, sent a warning message to the nearby connected vehicles (I2V communication). In the case of a connected bike and a connected vehicle that are approaching each other, the two vehicles received a warning message about their presence when a risk of collision is detected.

Demo 2 “Urban Georeferenced Alerting” in open roads  

TIM, FCA, Links Foundation, City of Turin with 5T, and Politecnico di Torino showed how the Local Traffic Authority in Turin intends to notify drivers in real time of possible dangers and special situations on the road (traffic jam, road works warning, dynamic speed limit, etc.). A standard geo-referenced warning message was dispatched to a TIM AMQP broker” at the edge of the 5G mobile network and only the involved vehicles received the geo-localized message from the AMQP Broker using the TIM 5G Network. The warning was read and displayed in an FCA vehicle through the on-board HMI and can for instance notify the driver of upcoming speed reduction. The aim of the trial was to demonstrate how the TIM 5G Network is suitable for realizing smart roads services for connected cars. The solution is compliant with the standards so it can be applied in other locations covered with mobile networks. 

Demo 3 Intersection Movement Assist (IMA), Forward collision Warning (FCW)  

FCA and Harman Samsung showcased two Vehicle to Vehicle (V2V) demos, by integrating C-V2X direct-short range communication into Maserati Levante and Quattroporte. The vehicles, through a direct radio link (network-less radio link), anonymously communicated basic information such as their position and related direction. 

The Forward Collision Warning (FCW), detected possible frontal collision and warned the driver accordingly. The Intersection Movement Assist (IMA), assisted the driver at the cross junctions to avoid a possible lateral collision with an oncoming vehicle. 

Demo 4 Emergency Electronic Brake Light (EEBL), Stationary Vehicle Warning (SVW)  

FCA, Continental, and Qualcomm demonstrated fast and reliable information exchange between vehicles in emergency situations. The two demos are based on C-V2X direct-short range technology, enabling Vehicle-to-Vehicle (V2V) communication between two Jeep Renegade. There were two portions to this demo: 

• “Stationary Vehicle Warning” (SVW): when the hazard lights are activated, the application broadcasted a message to all nearby vehicles so that approaching vehicles could be informed even if the hazard was not visible.  
• “Emergency Electronic Brake Light warning” (EEBL): in the event of a sudden braking, the application broadcasted a message to following vehicles, such that approaching vehicles were notified of the potentially dangerous situation. 

Demo 5 See-through 

Vodafone, FCA, Vodafone Automotive, Marelli and Altran revealed the ‘See Through’ that uses C-V2X long-range cellular network communication to exchange streamed video in real time between vehicles, extending the driver’s visual range under obstructed visibility scenarios and to prevent accidents, especially those that may occur in an overtaking phase. The two involved Jeep Renegades vehicles were equipped with a connectivity solution (Marelli) and high frame-rate cameras (Marelli Motorsport) to detect the road lanes.  

A real time tracking system and a space mapping algorithm of the vehicles, specifically developed by Vodafone Automotive, allowed Vodafone’s Multi-access Edge Computing (MEC) to dynamically manage and route the video flows on the basis of the vehicles’ relative positions and to ensure minimal end-to-end latency in the interest of drivers’ safety. Vodafone 5G ultra-low latency and high reliability were paramount to ensure the flow and synchrony of the real-time video exchange between vehicles, also under high traffic and cell saturation conditions. 

Demo 6 World-first 5G-enhanced ADAS services 

Audi, Ericsson, Italdesign, KTH, Pirelli, Qualcomm, TIM and Tobii showed how smart cars, commercial 5G smartphones and 5G networks jointly improve comfort, safety and efficiency. This unique collaboration combined the power of eye-tracking glasses, intelligent tires, in-vehicle augmented reality and 5G phones to work together over a live 5G network. With its high capacity and low latency, cellular 5G connectivity is ready to enable instantaneous cooperation between vehicles, the IoT ecosystem and more advanced driver assistance services. The live demonstrations at the Turin Lingotto test track were based on TIM’s commercial 5G network delivered in Turin in partnership with Ericsson. Audi cars, equipped with Pirelli Cyber Tyre, and embedded 5G modems provided by Qualcomm and available 5G smartphones were utilized to enhance pedestrian’s safety.

The 5G Automotive Association (5GAA) is a global, cross-industry organisation of companies from the automotive and telecommunications industries, working together to develop end-to-end solutions for future mobility and transport services.

Following its vision, 5GAA has rapidly expanded to include key players, namely the automotive manufacturers, Tier-1 suppliers, chipset/communication system providers, mobile operators and infrastructure vendors. More than 120 companies have now joined 5GAA. Diverse both in terms of geography and expertise, 5GAA’s members are committed to helping define and develop the next generation of connected mobility and automated vehicle and intelligent transport solutions.

5GAA is willing to engage with the Chinese government and eco-system to accelerate the growth of the automotive industry and connected-automated driving services in China. Regarding Electronic Toll Collection (ETC) Onboard Unit (open for public comment), 5GAA fully supports the targets to phase out physical tolling stations in China and would like to share some views on introducing C-V2X technology to fulfil this function:

1. Our research and field tests indicate that C-V2X offers high network security and reliability, as well as better performance in terms of coverage and latency compared to other existing alternatives. 5GAA believes that enabling electronic toll collection (ETC) via C-V2X would offer significant benefits. 5GAA is acting to include tolling as one of the most critical use cases supported by C-V2X. In addition, we noticed that the Society of Automotive Engineers (SAE) V2X Technical Committee has worked on a similar objective. More importantly, in addition to vehicle-to-infrastructure (V2I), C-V2X supports vehicle-to-pedestrians (V2P), vehicle-to-vehicle (V2V) and vehicle-to-network (V2N), encompassing all scenarios of smart mobility;
2. C-V2X is the future-proof technology to evolve from LTE-V2X to NR-V2X and so on;
3. C-V2X has matured thanks to broad cross-industry support. Major carmakers are now speeding up the business cases and pre-installation of C-V2X in their vehicles. For example, 5GAA released its C-V2X deployment roadmap at the beginning of 2018 and expects the first batch of C-V2X-equipped cars to be commercialised as early as 2020.
4. With regard to industry development, 5GAA believes there are two phases for C-V2X to be implemented and to enable all services needed to realise intelligent transport:

• Phase I: Utilising the existing C-V2X mature products and industry’s support, including chipset, devices, vehicles and communication equipment, to address tolling service for highway scenarios.
• Phase II: Based on C-V2X and its implementation in diverse categories of terminals like mobile phones (pre-installed and after-market), foster V2I synergy for the next ten years, e.g. highway tolling, Mobility as a Service (MaaS), for V2P, as well as road safety and coordinated driving for V2V.

5GAA believes C-V2X technology is a critical technology enabler for in-vehicle ETC technology and recommends including C-V2X into the Chinese national standard covering the Electronic Toll Collection Onboard Unit.

Recently, the 5G Automotive Association (5GAA) filed a petition for waiver with the Federal Communications Commission of the United States requesting that C-V2X be allowed to operate in the upper 20 MHz (5905 MHz – 5925 MHz) of the US ITS band.

In support of this petition, 5GAA member companies have performed a series of tests in an attempt to address anticipated technical questions related to the favourable implementation of this petition. The report describes the test procedures and results that were undertaken to support the 5GAA C-V2X FCC petition for waiver in the 5.9 GHz band.

The report presents results of testing C-V2X in 20-MHz wide CH183 – the channel that has been recently proposed for C-V2X deployment in the ITS band and is referred to as basic C-V2X Channel and it allows for V2V and V2X messages such as basic safety message (BSM), signal phase and timing (SPaT), signal request message (SRM), signal status message (SSM), and others covered by the Road Safety Message under development in SAE standards. The upper part of the ITS band was chosen to minimize impact to DSRC channels, especially CH172.

The viability of C-V2X in 10 MHz has been demonstrated in a preceding report in which C-V2X has been shown to outperform DSRC in terms of reliability, resilience to out-of-band interference and range. This report extends these results by showing that a BSM message sent in 20‑MHz CH183 has the same reliability as previously shown in 10-MHz CH184.

Both lab and field data included in the report demonstrate consistent results:

• C-V2X communication in 20-MHz CH183 has the same reliability performance (Packet Reception Ratio vs. distance) as the identical BSM-like message transmission in 10-MHz CH184.
• Impact of C-V2X high load transmissions in CH183 on DSRC basic safety transmissions in CH172 is negligible up to a 1.4-km range in LOS conditions
• Impact of C-V2X high load transmissions in CH183 on V2I and I2V transmissions in CH178 is negligible up to a 1.4‑km range in LOS conditions
• Impact of C-V2X high load transmissions in CH183 on V2I and I2V transmissions in CH180 is negligible up to 1 km in LOS Conditions
