Lexus Australia to partner with the Queensland Government in a trial of advanced technologies designed to improve road safety and reduce congestion, fuel consumption and emissions.

Two specially equipped Lexus RX 450h F Sport SUVs will be fitted with sensitive equipment that will enable them to communicate with each other and with roadside infrastructure such as traffic lights, as part of a two-year trial. The study into cooperative intelligent transport systems (C-ITS) technologies provides drivers with early warnings, including visual and audible alerts, covering a wide range of road and traffic conditions. Information will be shared between vehicles and infrastructure using dedicated short-range communications (DSRC) technology.

Advanced safety features already standard on the RX 450 F Sport include a forward collision-warning system with audible and visual alerts, autonomous emergency braking and automated lane-keeping.

Additional vehicle-to-vehicle and vehicle to infrastructure technologies to be added to the two vehicles are:
• Emergency electronic brake light: Alerts drivers to a cooperative vehicle that is braking hard some distance ahead.
• Slow/stopped vehicle: Warns the driver when a vehicle ahead is stopped or travelling slower, and there is a risk of rear-end collision.
• Advanced red-light warning: Alerts drivers that they likely to violate the red light unless they apply the brakes.
• Turn warning – vulnerable road user: Alerts drivers that a pedestrian or cyclist has pushed a signal call button and are crossing during the permitted phase.
• Road hazard warning: Alerts drivers to hazards, such as debris or water on the road, or a crash.
• Back-of-queue warning: Alerts drivers to a downstream queue on motorways using the Managed Motorways automated back-of-queue algorithm.
• In-vehicle speed warning: Provides drivers with information about active, static or variable speed limits.
• Road works warning: Notifies drivers approaching or driving through roadworks zones, providing speed information and alerting them if they are exceeding roadworks speed limits.
