Abstract

The major aim of this study is to compare the geographic variation in fatal crash rates per capita for license holders in NSW. For each Local Government Area (LGA) in NSW, the number of fatal crashes was obtained from the Roads and Traffic Authority's (RTA's) Traffic Accident Database. The fatal crash rate per 10,000 license holder years was calculated for each LGA, and mapped using GIS software. A Poisson distribution was used to calculate upper and lower confidence limits for the number of fatal crashes in each LGA. Fatal crash rate indicators generated through this process were also mapped. The three maps were then compared. Geographic clumping of 'high risk' areas was evident around major urban population centres when raw fatal crash numbers (by LGA) were mapped. However, when fatal crash rates per license holder were mapped, the pattern of geographic clumping moved from urban to rural and regional areas of the state. A broadly similar pattern was found when mapping the crash rate indicator data. (Author/publisher) For the covering entry of this conference, please see ITRD abstract no. E210298.
