SH58: chilling statistics

NZTA has added "accident" signs on SH58. Photo by me.
There's a mountain of reports to read on SH58, but one that just recently pointed out to me NZTA Report on State Highway 58 Strategic Study – a long-term strategic plan for State Highway 58 to 2029, from August 2010.

I'm still working my way through the report, but here's some of the chilling statistics:
  • A total of 1,009 crashes were reported along the SH58 Corridor length in the 20-year period from 1989 to 2008 inclusive;
  • Analysis of the crash data for the 5-year period from 2004 to 2008 indicates that there are currently an average of about 16 injury crashes, 52 total crashes and crash costs of about $5.3 million per annum along the SH58 corridor;
  • Mid-Block Crashes From 2004 to 2008, there have been a total of 166 reported mid-block crashes comprising: 
    • 1 fatal crash (one fatality), 
    • 8 serious injury crashes, 
    • 42 minor injury crashes, and 
    • 115 non-injury crashes. 
Meanwhile, NZTA has added "accident" signs west of Mt. Cecil Road, where the most recent accident resulting in the death of Upper Hutt local (and old schoolmate of mine) Richard Van Der Linden. They've re-chipped the sharp bend next to some subsidence occurring by the safety barrier and painted large speed numbers on the road (the area is now down to 50km/h). If this is all the safety upgrades NZTA is going to be doing, then there is a major problem for the people of upper Hutt Valley and Porirua who use the road daily.
