The South Australian Government is to trial technology which triggers safety measures when vehicles are detected approaching intersections. It is to be installed at four key rural locations in South Australia in an effort to reduce fatal and serious crashes by slowing motorists and making them aware of an approaching intersection.

The Rural Intersection Active Warning System is able to reduce the speed limit when it detects vehicles approaching an intersection.

The technology works by detecting a vehicle on the minor road approaching the intersection. It lowers the speed limit on the major rural road by changing the electronic speed limit sign on the major road.

It was originally developed in Sweden and is currently in use in New Zealand where, together with static safety signs which warn vehicles to slow or alert motorists to intersections ahead, it is said to slow vehicles by as much as 20kmh.

It is hoped they will encourage a safe and steady traffic flow by monitoring the average speed of vehicles through the works to ensure the safety of both road users and road workers. The cameras are expected to go live on 20 July and will remain in place until the completion of the project in spring 2017.

    The government of New Zealand aims to improve road safety in the country by installing more speed cameras nationwide. Currently, the ratio of speed cameras per 100,000 people stands at 1.3 compared to 2.5 and 4.8 in the Australian states of New South Wales and Victoria respectively. The New Zealand Transport Agency is to be allocated US$8.05 million to increase the number of speed cameras from the existing 55 units to 100 or more by 2015.
