Abstract: Road safety risk assessment tools are increasingly being used in New Zealand to help understand the crash risk on roads, at intersections and other sites (eg. bridges and railway crossings). Two such tools for rural roads are the KiwiRAP road ratings and RISA (Road Infrastructure Safety Assessment). KiwiRAP has been used to assess the relative safety risk along the State Highway network, while RISA is a tool used to assess the relative safety of a sample of local authority rural roads, as an alternative to existing road audits. Neither tool is particularly good at assessing the safety of rural intersections. The development of such a tool is well overdue. Christchurch City Council are in the process of developing and trialling a rural intersection road safety risk assessment tool (for priority controlled intersections) for local authority roads. This paper will discuss the local and international research on crash prediction models and crash reduction factors that was collated for rural intersections for this project. It also presents the risk assessment tool that is being developed, and how it will be applied. Along with all injury crashes, the tool also predicts the risk of fatal and serious crashes at rural intersections, by utilising adjusted severity factors from the High Risk Intersection Guide.
