Audi Q8 taught to communicate with road infrastructureOctober 13, 2020
Audi of America, American Tower Corporation, Qualcomm Technologies, Inc., and the Virginia Department of Transportation (VDOT) have announced the completion of one of the early stages of deployment of the C-V2X (cellular) communication technology for exchanging information between a vehicle and its environment. vehicle-to-everything).
The introduction of the technology on Virginia’s roads is the result of a joint project between Audi of America, VDOT and Qualcomm Technologies, which was announced earlier this year. Its goal is to improve safety in road works areas, reduce the number of road accidents and accidents. Participating companies are exploring new implementation models with the involvement of government and commercial organizations. This should accelerate the deployment of C-V2X technologies on the roads around the world. Collaboration with the Virginia Tech Transportation Institute (VTTI) and Commsignia, a provider of V2X solutions, helped complete an important milestone in the C-V2X project. The information is transmitted in the 5.9 GHz band, which the Federal Communications Commission (FCC) has proposed for C-V2X road safety systems.
The rollout of C-V2X technology on Virginia’s roads gives participants the opportunity to explore the benefits and deployment models for two specific scenarios where it will play an important role. This is the safety of road workers and vehicles in the work areas and the transmission of information about traffic signals. While the capabilities of C-V2X technology are far from limited to these two scenarios, they are especially attractive to project participants, as they lay the foundation for further widespread adoption.
Not only drivers, but also road workers can receive messages about the approach of the vehicle to the road works area through the direct communication channel with low latency. In this project, special vests with integrated C-V2X transceivers were developed for workers, and Qualcomm C-V2X platforms were installed on Audi Q8 test vehicles. Thus, drivers and road workers are aware of each other’s presence on the track.
To improve safety and efficiency, traffic signal controllers broadcast information about the status of traffic lights on Commsignia’s roadside infrastructure. The latter uses C-V2X technology to send messages to the Audi Q8 SUV class. The information in the messages complements the data of the current Audi Traffic Light Information (TLI) service, which informs drivers via cellular communication about the time remaining until the green signal changes. Additional C-V2X messages and audible alarms increase safety by warning of possible driving through red lights.
American Tower Corporation in this project provides a neutral host model infrastructure, engaging public and private organizations and facilitating the provision of C-V2X security and mobile services. The Virginia Transportation Institute of Technology has developed software and systems to support the primary scenarios identified for the initial phase of the project. Commsignia supplies RSUs and intelligent transportation systems (ITS) stack for the road and airborne modules.
“We expect neutral hosted infrastructure and public roadside RSUs to play a key role in the deployment of C-V2X technology in Virginia’s connected transport corridors,” said Ed Knapp, American Tower’s director of technology. “We’re excited to partner with leading organizations to find ways to accelerate the adoption of C-V2X technology and scale up the deployment of 5G edge infrastructure. The widespread deployment will help realize the concept of smart roads and intersections, improve the safety and efficiency of communications, improve the environment and the overall quality of life. “
The introduction of C-V2X technology into the Virginia Intelligent Highway Corridor paves the way for a new generation of vehicles. They are able to communicate with roadside infrastructure and vulnerable road users not only through the cellular network, but also directly. Today – in the event of a possible collision or even a traffic violation – they will warn the driver and help him feel more confident, and tomorrow they will act automatically in such situations, the American office of Audi noted.
“We are proud of our partnerships with Audi of America, American Tower Corporation and Commsignia, the Virginia Transportation Authority and the Virginia Transportation Institute of Technology. We have been able to not only demonstrate to the public and all stakeholders the development and benefits of C-V2X technology, but also create innovative designs that pave the way for widespread adoption, ”said Jim Misener, Senior Director, Qualcomm Technologies, Inc. product management. “The Virginia project will serve as a successful demonstration of public and private partnerships to dramatically improve safety and mobility with C-V2X technology.”
C-V2X technology is designed to provide low-latency, direct, low-latency communications between vehicles, roadside infrastructure and vulnerable road users in a dedicated 5.9 GHz band, without the need for cellular communications and without the need to subscribe to a cellular network. The C-V2X’s direct communication in the vehicle and on the road is synergistically complemented by cellular communication. This technology is already integrated into Qualcomm Technologies’ latest 4G / 5G automotive platforms for the next generation of telematics devices. Supported by new roadside infrastructure development models, they will be able to accelerate the adoption of C-V2X technology. Coordinating the development of C-V2X technology with the established cycles of the automotive design and cellular ecosystem is very promising. At the same time, the strong evolutionary potential of C-V2X technology opens up new rich and differentiated opportunities to support the global deployment of 5G.
