Attitudes towards current and lowered speed limits in Australia.

The present study was concerned with gaining a greater understanding of the Australian community's attitudes towards both the current and proposed lower speed limits. An online survey was administered in four states (Victoria, South Australia, Western Australia, and Tasmania), with a total of 4100 respondents recruited. The survey focussed on attitudes towards speed limits for four different road types, and the sample was stratified according to age, gender, and area of residence.

Cost-benefit analysis of an alcohol ignition interlock for installation in all newly registered vehicles.

Objective: This study conducted a cost-benefit analysis of an alcohol ignition interlock device in preventing alcohol-related fatalities and serious injuries when installed in all newly registered vehicles in Australia.

Methods: Benefit-cost ratios (BCRs) were calculated by comparing the benefits associated with the number of road injuries the interlock was predicted to save with the costs associated with installing the device in all newly registered vehicles. Four effectiveness levels were assumed for the interlock, given that the device was not expected to prevent 100 percent of alcohol-impaired driving.

The potential for automatic crash notification systems to reduce road fatalities.

This predictive study investigated the effectiveness of Automatic Crash Notification (ACN) systems in reducing road fatalities, due to enabling faster emergency medical services (EMS) notification times, and therefore, the earlier provision of treatment. The cost-effectiveness associated with fleet installation of ACN systems in Australia was also evaluated. A range of data sources were used to identify the range of road fatalities that ACN systems could potentially mitigate, with urban and rural crashes analyzed separately, due to the average EMS notification time being slower for rural areas.
