Panel 6: V2X Connectivity and Learning on the Road towards Cooperative Automated Driving

Thursday 16 September, 18:00-20:00 (UTC/GMT +3)

After more than two decades of huge industrial and academic research efforts, cooperative automated driving (CAD) is close to being a reality and to revolutionize our mobility.

Vehicle-to-everything (V2X) connectivity will complement embedded sensors (encompassing RADAR/LIDAR, cameras, positioning-systems) by letting vehicles exchange data with nearby vehicles, pedestrians, roadside-infrastructure as well as with remote entities. Several technologies are currently available and still evolving to support V2X connectivity (e.g., 802.11p/802.11bd, Cellular-V2X and its new 5G NR-based evolution), also pushed by several initiatives and standardization fora (e.g., IEEE, 3GPP, ETSI, 5GAA, Car2Car-Communication-Consortium).

Notwithstanding, the very strict application requirements, such as ultra-low latency (below 3ms) and high-reliability (up to 99.999%) demanded also under congested, harsh and highly-varying propagation scenarios, highly challenge existing connectivity solutions and entail the investigation of more disruptive techniques which are under discussion in the 5G and beyond research arena. On the other hand, sophisticated machine learning (ML) algorithms, implemented in edge/cloud facilities, are required to properly mine the big amount of collected data, to allow human drivers and self-driving vehicles to build an accurate perception of their surroundings and make decisions accordingly.

The design of innovative V2X connectivity and ML techniques for CAD (with their synergies still to be fully disclosed) will contribute to safer, smarter and greener driving paving the way for intriguing interdisciplinary research opportunities which motivate this panel. It will bring together leading experts from academia and industries representing key players active worldwide in the V2X R&D community and spanning automotive and telco vendors. They will discuss the state-of-the-art and share their views about the key V2X and ML solutions. Such insights are expected to fuel a fruitful discussion among the panelists and with the audience on potential cutting-edge technology trends having a lasting impacting the next years as key drivers for the genuine CAD take-off.


  1. Which would be the killer applications in the CAD realm which would challenge more V2X connectivity and/or ML techniques? Which is the main societal impact expected from them?
  2. How do you see the evolution of connectivity solutions in the next 2-to-5 years and which communication/networking technology on the horizon for 6G you will suggest to investigate as the game changer to improve performance of next-generation connected vehicles?
  3. Which role do you foresee for ML to optimize the V2X connectivity and application-layer CAD performance?
  4. As disruptive technologies and solutions are coming into the V2X picture (e.g., higher spectrum, unconventional access techniques, ML) which is the role of evaluation tools like simulators, prototyping and real-world datasets for accelerating the transition of the main breakthroughs from the lab to the market?
  5. As demonstrated in the last years, CAD needs to overcome a large number of different issues, including people’s skepticism, potential legal/regulation uncertainties, security threats, and a different evolutionary speed between the automotive and the telecom world. Which do you think will be the aspects that mostly risk to breakdown the deployment in the next years?
