NEW ZEALAND TRAFFIC DATA COLLECTION SYSTEM . 15TH ARRB CONEFRENCE, DARWIN, NORTHERN TERRITORY, 26-31 AUGUST 1990; PROCEEDINGS PARTS 1 TO 7

For many years up until 1986, traffic volumes on the New Zealand State Highway network were determined from a two level counting system of control stations counted one week per month, and short term stations counted for one to three one week blocks annually. The difficulties with the system were in determining a representative week for each month and a diversity in data collection standards. To solve these difficulties it was decided to implement a network of forty-six telemetry-based permanent traffic counting stations. Station locations were based on existing control stations, establishing cordon lines, monitoring of inter-regional traffic, and an appropriate mix of AADT. Golden River counter/classifiers were utilised in conjunction with loop sensors. Technical considerations are discussed including power supply, communication and installation. Data collection amounts to 5.5 Mbytes per month and the processing, reporting and the use of the data is described. A performance based maintenance contract ensures that data loss is minimised. Annual hourly flow profiles from nine stations confirms the bimodal distribution for New Zealand State Highways. Axle and EDA ratios are derived from the first weigh-in-motion station and a draft vehicle classification scheme for New Zealand developed. Further areas of research are proposed and future plans outlined. (Author/TRRL)
