ATP roadmarkings

Road markings with a vertical component are called audio tactile profiled (ATP) road markings in New Zealand. When used as an edgeline, they can be a nuisance for people on bikes if there is an insufficient shoulder. ATPs should not cause a problem, however, if relevant New Zealand guidelines are followed. These call for ATPs to be installed only when a minimum shoulder of 1.0 m is available, or when "all cycling interests in the area have been consulted, and agreement is reached with them". Here's what it says in the guidelines (from MOTSAM, Part 2, section 4.08.06):

(c) Cyclists

Gaps of at least 20 metres must be left in ATP edge lines where-ever cyclists may have a need to cross them, eg on bridge approaches, near narrow shoulders, near intersections or junctions with off-road facilities;

Shoulder widths clear of ATP edge lines must be a minimum of 1.0 metres to provide for cyclists - this requirement may only be contravened if all cycling interests in the area have been consulted, and agreement is reached with them;

On very narrow roads without shoulders, but where ATP edge lines would provide significant safety benefits, they may be placed hard against the edge of seal where cyclists are unlikely to ride. As above, all cycling interests in the area must be consulted and agreement reached with them.

To us, the guidelines are fine as they are. The problem is that too many applications can be found up and down the country where the guidelines have not been followed.
