On 24 November 2020, the 5G Automotive Association, in partnership with Euractiv, hosted a debate to discuss how C-V2X can contribute to reducing transport emissions.

To what extent can connected driving, with increasing levels of automation, lead to environmental benefits? To answer this question, 5GAA asked Dutch non-profit organisation TNO to conduct a study into the environmental effects of V2X communication as it is currently used in transport and as it can be used in future implementations.

During the event, the organisation presented the results of the study. These highlighted the specific C-V2X functionalities that offer the biggest emission reductions and therefore a contribution to the EU’s climate goals.

Indeed, at the time of the broadcast, the European Commission was working the Sustainable and Smart Mobility strategy, proposing measures that match the ambition of the recently updated emissions reductions goals. Policymakers aimed to leverage digitalisation and automation to create a more sustainable future for the transport and mobility sector.

Watch the video below to have some highlights of the event.

The present report represents the latest version of the first set of Use Case descriptions (Volume 1 – previously named WAVE1) developed in the context of the 5GAA WG1 work item “Use Case and KPI requirements”. The report introduces and explains the WG1 approach to describe Use Cases and their Service Level Requirements (SLRs). It includes a framework for the Use Case descriptions and a framework for Use Case Service Level Requirements collection. The two frameworks are applied to the Use Cases provided in the 5GAA Board Internal Guidance Document.

There is increased interest in the potential environmental benefits of C-V2X, given that substantial transport emissions reductions are required to help mitigate climate change, and the upcoming EC Strategy on Sustainable and Smart Mobility which intends to propose matching measures to the “unprecedented ambition to achieve 90% reduction in emissions by 2050”. The question is to what extent connected driving, with increasing levels of automation, can lead to environmental benefits. 5GAA, the 5G Automotive Association, asked TNO to conduct a study into the environmental effects of V2X communication as it is currently used in transport and as it can be used in future implementations.

Presentation of the study

Connected vehicles, as part of the emerging Cooperative Intelligent Transportation Systems (C-ITS) are positioned to transform the future of mobility – a change enabled by the exchange of messages between vehicles and between vehicles and transport infrastructure. As these messages are constantly broadcasting data, including vehicle speed and location, this raises potential concern about how to address privacy and data protection.

In this document, we take a fresh look at the latest technological architectures that feature Privacy by Design. We focus specifically on Cooperative Awareness Messages (CAM) and Decentralised Environmental Notification Messages (DENM), where privacy protection is offered by using pseudonym certificates that do not contain any identifying information. A Public Key Infrastructure (PKI) system takes care of the provision and overall management of the corresponding cryptographic keys. In this document, we review how current PKI system design can help address the risk of tracking from outside and inside attackers, and we identify challenges and privacy risks that remain unresolved. We give some suggestions in terms of future research and conclude the document with general recommendations.

5G Automotive Association (5GAA) has defined a methodology to describe solution agnostic automotive use cases (UC) and application requirements referred to as Service Level Requirements (SLR).

This White Paper applies the defined methodology to describe use cases, and includes advanced UCs that require complex interactions among vehicles as well as between vehicles and infrastructure in relation to self-driving (autonomous) vehicles. Different road scenarios, actors and service flows are considered in the defined use cases. Detailed analysis of the derived Service Level Requirements is also provided.

ETSI specifications ensure interoperability, safety, and security of C-V2X technology development

In July 2020, the 5G Automotive Association (5GAA) partnered with global ICT standards organisation ETSI to organise a remote cellular-vehicle-to-everything (C-V2X) Plugtest. The LTE-V2X System Profile is the first of its kind to be specified by an independent, accredited standards organisation in Europe (ETSI TS 103 723).

The system profile provides industry wide upper layer configuration guidelines for C-V2X deployment and employs C-V2X technology from 3GPP Release 14. The system profile and the global standard it represents will lay the foundations for standardised direct cellular communications technology in the automotive sector; making product development faster and ensuring that safety and security are at the core of all new technologies.

“LTE-V2X provides a seamless evolution path towards 5G employing new radio V2X (NR-V2X). The latter will allow even better performance and further enhanced features, while keeping backward compatibility with LTE-V2X”, said Maxime Flament, CTO, 5GAA. “OEMs will especially benefit as the technology will allow long life cycles, which are essential for automotive products.”

Several automotive LTE-V2X devices were successfully tested during the second ETSI C-V2X Plugtest™ in addition to Intelligent Transport Systems (ITS) stations and Public Key Infrastructure (PKI) vendors in order to assess the level of interoperability of their implementation and to validate the ETSI ITS specifications. An overall interoperability success rate of 94% was achieved during the second ETSI C-V2X Plugtest.
