New Zealand state highway: skid resistance successes

The relative effectiveness of the different approaches to skid resistance management of road networks adopted by Transit New Zealand and Territorial Local Authorities was therefore established through time-series movements over the 12 year period from 1995-2006. The above findings confirm that although there has been an annual increase of about 3.2 per cent in the vehicle-kilometres travelled on the State Highway network over the 12 year period 1995-2006, Transit New Zealand's T/10 specification has been effective in bringing about a steady reduction in reported "wet" injury crash rates and maintaining the "all" injury crash rates to 1998 levels on rural sections of the state highway network. The analysis has also demonstrated that in order to obtain meaningful comparisons between years and between state highway and local roads, greater attention has to be paid to obtaining accurate traffic exposure figures and a need to incorporate annual rainfall data at a regional level when investigating trends in wet road crash rates.
