MOTOR VEHICLE CRASHES IN NEW ZEALAND <strong>2011</strong><br />
OPEN ROAD CAR SPEEDS<br />
In the survey <strong>of</strong> open road speeds <strong>of</strong> cars carried out <strong>in</strong> July and August <strong>2011</strong>, approximately 13,000 cars were surveyed at 68<br />
sites around the country.<br />
The speed surveys are designed to monitor changes <strong>in</strong> free speeds <strong>of</strong> vehicles. That is, speeds atta<strong>in</strong>ed when the vehicle is<br />
unimpeded by the presence <strong>of</strong> other vehicles (i.e., there is some distance between a vehicle travell<strong>in</strong>g at a free speed and the<br />
vehicle <strong>in</strong> front <strong>of</strong> it) or by environmental features such as traffic lights, <strong>in</strong>tersections, hills, corners or road works. By monitor<strong>in</strong>g<br />
the speeds <strong>of</strong> unimpeded vehicles these surveys measure driver choice <strong>of</strong> speed.<br />
The regional surveys are designed to track changes over time <strong>in</strong> driver speed choice with<strong>in</strong> regions. They are not designed to<br />
provide valid comparisons between regions.<br />
