EVALUATION OF THE EFFECT OF COMPULSORY BREATH TESTING AND SPEED CAMERAS IN NEW ZEALAND

This paper reports on the results of a preliminary analysis of the monthly series of Fatal and Serious casualty traffic crashes in New Zealand during the period 1990-1995. The primary changes and safety initiatives examined here are the introductions of Compulsory Breath Testing (CBT) and Speed Cameras. The data for this analysis are taken from the Traffic Crash Report (TCR) database of Police reported crashes maintained by the Land Transport Safety Authority of New Zealand (LTSA). The analysis to date has focussed on crashes by: (1) Speed Limit Area (Urban/Rural); (2) Time of Day as a reflection of alcohol related risk (High/Low risk); (3) The analysis has detected effects on the total number of serious and fatal crashes attributable to the changes. While CBT effects appear across the board, speed cameras have predominantly affected urban areas and the effect at their specific, signed, deployment sites has been greater man at other places. The effects of the individual changes, when combined as a single safety program, are worthwhile, but present room for improvement.
