Elements of a Point-to-Point Average Speed Camera System

Kingston

Under section 146D of the Land Transport Act 1998, Publication of matters relating to point-to-point average speed system, the Director must publish the elements of a point-to-point average speed system, by notice in the New Zealand Gazette and on an internet site maintained by the Agency.

Under section 146A(3) of the Land Transport Act 1998, an element of a point-to-point average speed system, means 1 or more of the following:

the 2 items of approved vehicle surveillance equipment at the detection points:
the location of the 2 detection points:
the surveyed distance between those 2 detection points:
if only 1 speed limit applies between those 2 detection points, that speed limit:
if more than 1 speed limit applies between those 2 detection points,—

those speed limits;
when those speed limits apply;
the intermediate surveyed distance for each speed limit; and
the weighted average speed limit between those 2 detection points, as calculated under section 146B.

The elements required for the Point-to-Point Average Speed Camera system are outlined below:
