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.

    Oregon Department of Transportation (ODOT) has implemented digital variable speed limit signs over a thirty-mile stretch of Interstate 84 between Baker City and La Grande, replacing the standard speed signs in that area. The new signs will use traffic, road, weather and visibility sensors to lower the legal speed limit when ice, snow, fog or a wreck ahead requires drivers to slow down. Along with identifying the current legal speed limit, the digital displays can also show the reason for a reduced speed,

    In-vehicle anti-collision systems continue to evolve and could eliminate some incidents altogether. John Kendall rounds up the current developments. A few weeks ago, I watched a driver reverse a car from a parking bay at right angles to the road, straight into a car driving along the road. The accident happened at walking pace, no-one was hurt and both cars had body panels that regain their shape after a low speed shunt.
