Each site was surveyed between 2 pm and 4 pm on Sunday afternoons during the school term. Only adults seated in the rear window positions were included in the survey. There was no rear seat survey in 2012.

ROAD USER BEHAVIOUR SURVEYS 157 TABLE 3: CHILD RESTRAINTS IN CARS (PERCENT WEARING) In the survey carried out in October 2012, children aged under 5 years in more than 4,800 cars were observed at 112 sites around the country. The table shows the percentage restrained in appropriate child restraints. In the 2012 survey 52 percent were restrained in child seats, 19 percent in booster seats, 20 percent in infant seats and about half a percent in child harnesses. A further 5 percent were restrained by adult safety belts. The remaining 3 percent were not restrained at all. Children aged under 5 were not surveyed in 2011.

Each site was surveyed for two separate hours, typically between 8 am and 9 am, and between 3 pm and 4 pm, on normal school weekdays.

158 MOTOR VEHICLE CRASHES IN NEW ZEALAND 2012 OPEN ROAD CAR SPEEDS In the survey of open road speeds of cars carried out in July and August 2012, approximately 12,400 cars were surveyed at 67 sites around the country. The speed surveys are designed to monitor changes in free speeds of vehicles. That is, speeds attained when the vehicle is unimpeded by the presence of other vehicles (i.e., there is some distance between a vehicle travelling at a free speed and the vehicle in front of it) or by environmental features such as traffic lights, intersections, hills, corners or road works. By monitoring the speeds of unimpeded vehicles these surveys measure driver choice of speed. The regional surveys are designed to track changes over time in driver speed choice within regions. They are not designed to provide valid comparisons between regions.

ROAD USER BEHAVIOUR SURVEYS 159 URBAN CAR SPEEDS In the survey of urban speeds of cars carried out in July and August 2012, approximately 16,500 cars were surveyed at 64 sites around the country. The speed surveys are designed to monitor changes in free speeds of vehicles. That is speeds attained when the vehicle is unimpeded by the presence of other vehicles (ie, there is some distance between a vehicle travelling at a free speed and the vehicle in front of it) or by environmental features such as traffic lights, intersections, hills, corners or road works. By monitoring the speeds of unimpeded vehicles these surveys measure driver choice of speed. The regional surveys are designed to track changes over time in driver speed choice within regions. They are not designed to provide valid comparisons between regions.
