Distributed situation awareness in road transport : theory measurement and application to intersection design This book showcases through the use of simulation on road testing and human factors methods in an integrated manner. It achieves this by describing a programme of research designed to enhance situation awareness (SA) across different road users in Australia. The book also makes a telling contribution to the area of SA. Despite being identified as a key concept for road safety efforts along with many researchers calling for further research in this area SA remains ill defined underexplored and generally ambiguous in a road transport context. This book addresses this knowledge gap by proposing a new model of road user SA and specifying interventions designed to enhance it
