Rural Road Safety

ARSC conference 2017

In 2009 a crash study determined that a substantial rural road loss-of-control crash problem existed along Candia Road (Auckland). Crash remedial works were recommended, designed and installed along the study cordon (early 2010). In 2017 reported crash statistics were studied along the study cordon for a 7 year period 'before' and 'after' the crash remedial works were installed. The crash remedial works reduced reported crashes substantially, by 87%. Furthermore, $24 million in lifetime crash cost savings was achieved, with a very high Benefit Cost Ratio (19) and an average of 1.4 Death/serious injury crashes saved per year.
