Dear Bob ....
I am writing in reply to your email of 8 September about road crash statistics.
The LTSA and its road safety partners are very keen to obtain the greatest amount of information they possibly can on the crashes that are happening on the highways, in order to be able to improve their ability to apply remedies to those locations where crashes are occurring. As part of the continuing improvement of crash data availability, the Police are encouraged to report as many crashes as possible, and there has been an improvement in this aspect in recent years. It is therefore no surprise that the number of injury crashes reported by the Police has also increased in the last few years.
There are other ways of looking at road crash casualties, including the number of people hospitalised as a result of road crashes. Unfortunately these numbers have similar problems with the reliability of the data, due to changes in hospital admissions criteria which have occurred in recent years, particularly in the Auckland Region. For this reason the best indicator of progress in this area is the number of road crash casualties hospitalised for more than 1 day, which has steadily decreased by 5-6% each year since 1994.
Speed is indeed an important factor in road crashes, but certainly not the only factor. I would draw your attention to the LTSA'a website at www.ltsa.govt.nz which provides statistics and commentary on the major factors contributing to crashes, including speed.
I apologise for the delay in responding to your message.
Yours sincerely
