Abstract
The use of raw accident data, often perceived as a valid measure of the level of road safety (e.g. the number of fatalities) does not allow an accurate measure of safety to be obtained. This paper outlines the method developed for the collection of distance-travelled data and presents accident risk estimates by time of week for various driver experience groups. An exploratory attempt to detect changes in exposure following the implementation of zero BAC legislation is made and, given the overlap between alcohol-related and night-time accidents, the potential safety benefits of a driving curfew for novice drivers are examined.
