Evaluation of a warning system to reduce the risk of casualty crashes at rural junctions in South Australia.

Objective: This study evaluated the effectiveness and potential safety benefits of a Rural Junction Active Warning System (RJAWS), which uses variable speed limit signs (VSLSs) to temporarily impose a reduced speed limit along the major road when another vehicle is approaching on the minor road or turning into the minor road from the far-side major leg.

Methods: The RJAWS was trialed at 4 3-leg rural junctions between 2-lane roads in South Australia. A quasi-experimental before-after analysis was conducted.

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.
