|Title:||Understanding and Improving Safe System Intersection Performance|
|Jurewicz C, Sobhani A, Chau P, Woolley JE|
|Abstract:||Intersection crashes account for approximately 30% of severe injuries in Australia and New Zealand. This study sought to improve understanding of the key factors in intersection severe injury crashes, and to develop initiatives to improve the design of intersections for better alignment with the Safe System objective of minimising death and serious injury. The study reviewed recent literature and data to synthesise the following Safe System intersection design principles: minimise conflict points, remove/simplify road user decisions, minimise impact angles, and minimise entry and impact speeds. Using inputs from literature and data findings, a new safety analytical method, and practitioners, the study proposed nine innovative intersection design concepts seeking to increase Safe System alignment across a wide range of scenarios (urban/rural, new/retrofit). These design concepts form a starting point for practitioners’ trials and refinement. The study concluded that achievement of Safe System for intersections requires significant supporting contributions from emerging transport disciplines such as C-ITS, autonomous vehicles, and Movement and Place.|
