Wide centrelines, the road to a safer system

The Road to Zero, NZ’s Road Safety Strategy, targets a 40% reduction in Deaths and Serious Injuries by 2030. Within the context of a high-speed rural highway, head-on crashes account for a disproportionate number of deaths. median barrier is often the go to treatment and rightly so, with an expected reduction of 65% of high severity crashes (even as much as 90% reduction in head-on crashes) it is easy to see how this is the case. But how do we get to Median Barrier? Topography, narrow sealed pavements and frequent accesses often mean that it’s difficult and expensive to implement median barrier. Wide centrelines are an alternative to median barrier but are less effective and can result in projects having lower priority although they could be a considerable step towards a safe system environment. So how does wide centreline fit into a Towards Zero environment?
