Socio-economic benefits of cellular vehicle-to-everything could reach 43 billion Euros by 2035
The 5GAA published a report, authored by independent telecoms, media, and technology consultants Analysys Mason together with automotive consultancy SBD Automotive, which assesses the benefits of cellular vehicle to everything (C-V2X) technology for delivery of vehicle-to-everything (V2X) communication. The report, which has a focus on the benefits of such solutions in Europe, uses qualitative evidence and describes quantitative cost-benefit analysis that the consultants have undertaken relating to deployment of C-V2X.
C-V2X is a technology developed by the Third Generation Partnership Project (3GPP) to deliver V2X services, using two modes of communication:
- Direct vehicle-to-vehicle mode (called 'PC5' in 3GPP specifications)
- Network communications interface (called 'Uu' in 3GPP specifications) for vehicle-to-network (V2N) communication via existing mobile networks
The publication of 5GAA’s report coincides with policy development on V2X, and use of the 5.9 GHz band, in the European Union where the European Commission is currently undertaking a public consultation on deployment of cooperative intelligent transport systems (C-ITS).
The study concludes that the deployment of C-ITS systems is beneficial at the European Union level. Net benefits that could be accrued in Europe are estimated to be in the range of EUR20 billion to EUR43 billion in 2035 (with the highest benefits coming from increased road safety, and traffic efficiency), across the four scenarios modeled.
The most favorable scenario of those modeled in the study (amounting to EUR 43 billion net benefits) is where the potential for rapid penetration and economies of scale for C-V2X is maximized and both C-V2X and the Wi-Fi Standard IEEE 802.11p are able to co-exist in the 5.9-GHz spectrum band. Such benefits do not arise in a scenario where the use of IEEE 802.11p is mandated for C-ITS services, which would result in less than half these expected net benefits (EUR 20 billion).
The study also indicates that benefits of C-V2X for the European market lie in its deployment flexibility, with the ability to provide coverage for both short-range and wide-area applications, and certainty of future evolution to 5G, potentially facilitating earlier deployment as well as after-market deployment (e.g., V2X services provided in vehicles via a smartphone or other after-market device with C-V2X connectivity).
Reduced infrastructure deployment costs are a further key benefit of C-V2X, from the potential to reuse existing mobile infrastructure, and thus leveraging cellular technology integration and economies of scale, rather than building independently operated roadside infrastructure.
Christoph Voigt, 5GAA chairman, said, "C-V2X will be fundamental to the deployment of cooperative intelligent transport systems. The benefits highlighted in this report indisputably demonstrate that this technology will lead to major improvements in driving and road safety. It further highlights that the European Commission should take a technology neutral approach and not limit these benefits by mandating the use of the Wi-Fi standard IEEE 802.11p."

Separately, the 5GAA also published a study that carries out a quantitative analysis of LTE-V2X (PC-5) and IEEE 802.11p technologies for short-range ad hoc/direct communications in reducing fatalities and serious injuries caused by motoring accidents in the EU. The modeling underlying this report was peer-reviewed and validated by the technology and policy consultancy, Ricardo. The study finds that LTE-V2X (PC5) outperforms 802.11p in reducing fatalities and serious injuries on the EU's roads.

The 5G Automotive Association (5GAA) is a global cross-industry organization of companies from the automotive, technology, and telecommunications industries (ICT), working together to develop end-to-end solutions for future mobility and transportation services. Created in 2016, the association is comprised of more than 67 members whose mission is to develop, test, and promote communications solutions, initiate their standardization, and accelerate their commercial availability and global market penetration to address societal needs.
