A cross-sectional study of the prevalence of medical conditions as contributors to road crashes in South Australia.

Objectives: With the population of Australians aged 85 or older expected to double by 2042 and the association of increased age with the greater likelihood of having medical conditions, the potential for an increase in the number crashes caused by medical conditions is of concern. This study aims to understand the prevalence of medical conditions contributing to road crashes and the characteristics of these crashes, in order to guide development of strategies to mitigate the risks and harms involved.

Method: The sample consisted of 1,934 active road users (drivers, motorcyclists, cyclists, pedestrians) injured in crashes on South Australian roads who were admitted to the Royal Adelaide Hospital over the period 2014 to 2017.

A trial of retrofitted advisory collision avoidance technology in government fleet vehicles.

In-vehicle collision avoidance technology (CAT) has the potential to prevent crash involvement. In 2015, Transport for New South Wales undertook a trial of a Mobileye 560 CAT system that was installed in 34 government fleet vehicles for a period of seven months. The system provided headway monitoring, lane departure, forward collision and pedestrian collision warnings, using audio and visual alerts.

Understanding the context of alcohol impaired driving for fatal crash-involved drivers: A descriptive case analysis.

Objective: The objective of this study was to understand the social context and circumstances surrounding alcohol-impaired driving prior to fatal crash involvement for drivers with an illegal blood alcohol concentration (BAC ≥ 0.05 g/100 ml or 0.00 g/100 ml for restricted license holders).

How safe are children when transported by bicycle?

Objectives: With the increasing popularity of cycling generally and availability of new bicycle child carriers, there is an emerging interest in the safety of child bicycle passengers and riders. However, very little is known about the nature and extent of injuries to child bicycle riders and passengers. The aim of this study was to enhance our understanding of child safety in bike transportation and to identify injury patterns and outcomes.

The relative contribution of system failures and extreme behaviour in South Australian crashes.

Within the road system, there are compliant road users who may make an error that leads to a crash, resulting in a 'system failure', and there are also road users who deliberately take risks and display dangerous or 'extreme' behaviours that lead to a crash. Crashes resulting from system failures can be addressed through improvements to road system design more readily than crashes resulting from extreme behaviours. The classification of crash causation in terms of system failures or extreme behaviour is important for determining the extent to which a Safe System approach (i.
