MARKER POST DELINEATION STANDARDS TO INCREASE ROAD SAFETY

The incidence of vehicles running off rural roads at night in New Zealand could be significantly reduced with the implementation of new standards for road edge marker posts on state highways. These new standards include: a) high intensity sheeting for reflective markers giving twice the reflective area than at present; b) the spacing of markers around curves has been altered to provide adequate visibility of 4 markers in a vehicle headlight beam; and c) reflective markers will be placed on left-hand posts on the inside of left hand curves, rather than on the outside of curves as at present. This is to prevent the problem drivers previously had of negotiating left hand curves while trying to view reflectors through oncoming headlights. Improved delineation of centre lines using reflective raised pavement markers on all roads carrying 500 vehicles a day rather than those carrying 1500 vehicles a day will also be implemented. It is believed that such measures will prevent 50% of night accidents on curves. Details of the design and layout of the edge marker posts are provided.
