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.
Publication of the report coincides with policy development on V2X, and use of the 5.9GHz 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 modelled.
The most favourable scenario of those modelled 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 maximised and both C-V2X and the Wi-Fi Standard IEEE 802.11p are able to co-exist in the 5.9GHz 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 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 re-use existing mobile infrastructure, and thus leveraging cellular technology integration and economies of scale, rather than building independently operated roadside infrastructure.
Separately, the 5GAA has also today published a study which 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 modelling 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.
