Waka kotahi says new road safety cameras that track a cars speed over a length of road are way more effective at reducing crashes than fixed spot speed cameras. The so called point to point cameras average a vehicles speed over the journey between two cameras. They're being installed along stretches of six roads that are considered high risk crash areas in the Auckland region. The cameras will be tested for about about three months and data will be gathered before they're used for enforcement and tickets start being issued. Waka Kotahi's head of regulatory strategic programmes, Tara MacMillan, explains in more detail how the new cameras work.

It looks like instead of pinging carelessness, we will soon be keeping people to the speed limit.

With the reducing of speed limits being pulled, at least this will give another way to reduce the impact of crashes.

Unlike the comment on reddit saying this won’t reduce crashes, I’m going to point out that it’s not designed to. Road to zero is about recognising crashes will happen, this move is about reducing the damage when crashes inevitably occur.
