Technology which triggers safety measures when vehicles are detected approaching intersections are being installed at four key rural locations in South Australia.
The Swedish-developed Rural Intersection Active Warning System is able to reduce the speed limit when it detects vehicles approaching an intersection. It is currently in use in New Zealand where, together with static safety signs which warn vehicles to slow or alert motorists to intersections ahead, the technology has been found to slow vehicles by as much as 20kmh.
Rural Intersection Activated Warning Signs have been proven to reduce fatal and serious crashes by slowing motorists and making them aware of an approaching intersection.
The technology detects a vehicle on the minor road approaching the intersection, lowering the speed limit on the major rural road by changing the electronic speed limit sign on the major road.
The South Australian Government says that rather than further costly upgrades such as a roundabout, or introducing permanent speed reductions, this warning system is a comparatively low-cost initiative which will have substantial safety benefits.
