Telstra, Lexus trial C-V2X in Victoria

By

Telstra and Lexus are about to trial the use of C-V2X technology aimed at improving road safety.

The Telstra/Lexus plan is Australia's first connected vehicle field trial using C-V2X (cellular vehicle to everything) technology over 5.9GHz radios.

The partnership will explore various safety systems including emergency braking alerts, in-vehicle speed limit compliance warnings, right-turn assist for vulnerable road users and warnings when surrounding vehicles are likely to violate a red light.

Two Lexus 450h F Sport luxury SUVs will use C-V2X to talk to each other and to the environment around them via Telstra's 4GX mobile network and direct short-range wireless links.

"For instance, if a trial vehicle ahead performs an emergency brake, it will send this message to a V2X-equipped car following – potentially before a forward collision radar or driver notices the event. In these situations, mere milliseconds can make a huge difference," said Telstra chief technology officer Håkan Eriksson.

"We'll also be investigating other applications, such as how to securely send speed zone, traffic light timing, and other signals to cars so all this information can be available just-in-time and help prevent road trauma."

Other applications include the secure delivery of speed zone, traffic light timing, and other signals to vehicles.

Eriksson added, "The strength of Cellular V2X technology is that it combines both short range radios — which allows vehicles to communicate directly with one another using cellular technology, but without going via a cellular network — and wide-area 4G-based mobile communications when available. So, even in the case that there's no mobile coverage, the most urgent safety messages will still get through and help to save lives."

Telstra and Lexus have been awarded a $3.5 million grant under the Victorian Government's Towards Zero program.

"The role of Lexus as an innovator and leader in the development of advanced safety and traffic-management technologies is central to our parent company's global vision to reduce traffic fatalities to zero," said Lexus Australia chief executive Scott Thompson.

"It is significant that this ground-breaking trial involves our local connected vehicle services department along with VicRoads, the Transport Accident Commission and Telstra."
