Review of road safety targets in Western Australia

The objectives of this project were twofold: (i) to explore the feasibility of using hospital admissions data to develop road safety targets and to plan and evaluate performance, and (ii) to review the feasibility of setting separate targets for all road user groups and basing these targets on hospital data. The current situation is that police crash data are used as the basis for setting road safety targets, separate targets are not set for each road user group, and road safety performance is monitored for each road user group using police data. The study illustrated that the hospital admissions data provide a more accurate estimate than the police data of the number of road crash casualties admitted to hospital. The main problems with the police data are that they underestimate the number of hospitalised road crash casualties and under-report the relative shares of motorcyclists and pedal cyclists who are hospitalised. With respect to setting targets for each road user group, methods are available or can be developed to deal with the problems of having relatively small numbers for each road user group to set targets, and of allocating the road crash casualties of unknown road user type in the hospital data to specific road user groups. The main recommendations of the study are that hospital admissions data should replace the police crash data as the source used to set road safety targets for the number of hospitalised road crash casualties in WA and to plan and evaluate road safety performance, and that separate targets based on hospital data should be set for each road user group. The police data relating to the number of hospitalised road crash casualties should still be used as a road safety performance indicator to enable benchmarking against other Australian states and territories.
