Austroads recently released a new Research Report[1] (AP-R747-26) detailing the proposed implementation of national harmonisation of road safety audit (RSA) practices. The report describes a ‘Breakeven analysis’ approach to evaluating RSA benefits, rather than a more traditional cost-benefit analysis. This is due to a reported lack of published research on the ‘relationship between road safety audit quality  and outcomes (including crash risk and construction efficiency)’. Au

Self-explaining (or self-enforcing) roads were noted in our recent brief (#58)  as an integral part of Network Safety Plans. The concept of self-explaining roads (SER) is not a new one, with European researchers clearly articulating the need to design roads which align with driver expectations since the 1980s. As described by Theeuwes (1995): The so-called “Self-Explaining Road” (SER) is a traffic environment which elicits safe behavior simply by its design. [1] Early researc

As reported in our previous brief  on the topic, a Network Safety Plan (NSP) is a strategic plan to reduce crash risk across a network by prioritising investment in safety infrastructure and related measures. The current brief expands upon the previous entry with further details about NSP foundations, integration with related strategies and approaches, and anticipated benefits. NSPs are based on Safe System and Movement and Place principles, and consistency in applied standar
