Over half of road deaths, and nearly three quarters of serious injuries are caused by system failures on our roads. In other words, they are unforgiving of human error.
The cost to fix this is prohibitive - the reality is that we have a lot of roads and a relatively low population base to fund network improvements. There are 83,000 kilometres of local roads and around 11,000 kilometres of state highway throughout New Zealand and the length of road per person in New Zealand is one of the highest in the world.
It’s been suggested that it could cost between $5billion and $10billion dollars to improve the network so, even with all the will in the world, this isn’t going to happen any time soon.
We simply cannot afford to engineer our way out of this.
Roads don’t cause crashes, human error does. Speed, alcohol, failing to give way or stop and inattention continue to be the main contributing factors in fatal and serious injury crashes.
I often hear people blame a number of factors on crashes, but the analysis of fatal and serious injury crashes shows that:
- Speed continues to be is a major contributing factor. In 2016, in appropriate speed contributed to 21% of deaths and serious injuries in road crashes.
- Fatigue has an impact. In 2016 fatigue was identified as a contributing factor in 28 fatal crashes, 119 serious injury crashes and 438 minor injury crashes.
- Up to 30% of car crash fatalities involved people not wearing a seatbelt.
On top of this, the age and technology standards of a vehicle also contribute to whether or not there is an injury or fatality as a result of a crash. Last year 380 people died and more than 2,000 were seriously injured on our roads. What if the entire population of a town like Taihape was killed and/or seriously injured by an avoidable event? There would be understandable outrage.
Serious injuries and fatalities cause trauma for a lot of people and impact the whole of society. The effect of less trauma on our roads would be wide-felt. Why wouldn’t we do everything we can to protect ourselves and others on our roads?
