A new high tech warning system, which is intended to help to improve road safety, has been installed on State Highway 1 in New Zealand. The Rural Intersection Active Warning System at the turnoff to Moeraki Boulders is now operational and the variable speed limit is now legally enforceable.


The new warning system detects vehicles approaching the right turning bay at Moeraki Boulders Road and vehicles waiting to turn on to the highway and automatically adjusts the speed limit in the area to 70km/h to allow the approaching car to merge safely with oncoming traffic.  The 70km/h variable speed limit will apply 170 metres either side of the SH1/Moeraki Boulders Road.

The work is part of a wider programme of safety improvements being proposed along the highway.

Between 2006 and 2015 there were 21 deaths and 114 serious injuries on this stretch of the road and the government is committed to making these roads and roadsides safer to help prevent further tragedies.

“The variable speed limit will help to reduce the severity of crashes at the Moeraki Boulders turnoff by lowering the speed of highway traffic when necessary for the safety of other road users, while maintaining the current 100km/h speed limits when the intersection is not in use. This high tech system is a great alternative for all drivers in the region when compared with permanently reducing the speed limit in the area,” says associate minister of Transport Tim Macindoe.

    Sign language reduces human error says Clearview
    Wrong-way warning systems and advanced queue detection can help to reduce human error. They can also cut road accidents – and therefore road deaths, says Clearview Intelligence Where were nearly 1,800 deaths on the UK’s roads in 2018 – an average of five people dying each day. The largest single cause of serious injury is crashes at junctions (accounting for 33% of incidents), while the largest single cause of death was run-off road crashes (30%) “With vehicles increasingly being designed with saf

    When speed compliance becomes a safety issue
    David Crawford finds that softly, softly can be safely, safely when it comes to speed enforcement. Comedians and controversial TV presenters have long made jokes about having to watch the speedometer so closely as they pass speed camera after speed camera that they mow down bus queues. But the joke may have some factual basis according to a study by researchers from the University of Western Australia.
