Road traffic crashes are responsible for hundreds of lives and thousands of injuries on Australian roadways each year. A significant research opportunity exists to fundamentally rethink how the profession quantitatively identifies black spots on the transport network. This project aims to develop, test, and validate an evidence-based methodology to proactively detect motor vehicle crash black spots by decomposing (statistically) observed crashes at a site into their engineering, behavioural, and unobserved spatial components. The new methods combined provide novel insights and knowledge regarding transport network safety management.
