Lexus has expanded its leadership in advanced safety by taking a pivotal role in a high-tech connected-vehicle trial focused on reducing road trauma and improving traffic management.

New technology under test is designed to provide alerts to drivers about potentially dangerous situations, such as when another vehicle on an intersecting road is likely to run a red light or when vehicles further down the road have stopped suddenly.

In addition to road-safety benefits, the connected-vehicle technologies can also promote smoother traffic flow, helping alleviate congestion and reduce emissions and fuel consumption.

The trial involves two Lexus RX 450h F Sport SUVs which, due to their size and capabilities, form an ideal platform to test cooperative intelligent transport systems using cellular vehicle-to-everything technology.

Specialized equipment fitted to the vehicles adds to their capabilities by enabling them to relay critical safety information between each other and networks at super-high speed in situations where every millisecond counts.

The cars – like every new Lexus on sale in Australia – are equipped as standard with Lexus active safety systems that can help avoid collisions or mitigate the effects of an accident in a wide range of situations.

Following on-track development and testing at the Lexus test track in the Melbourne suburb of Altona, testing will now occur on Victorian roads.

The ground-breaking study brings together the Lexus connected vehicle services department along with VicRoads, the Transport Accident Commission and Telstra.

Lexus Australia chief executive Scott Thompson said the company was proud to be the leading automotive brand for connected-vehicle research in Australia.
