Safe System Assessment Framework

Abstract

This report proposes an assessment framework designed to help road agencies methodically consider Safe System objectives in road infrastructure projects.

The framework considers key crash types that lead to fatal and serious crash outcomes, as well as the risks associated with these crashes (exposure, likelihood and severity). It provides prompts to ensure each pillar of the Safe System are considered. A treatment hierarchy is also provided to help identify the most effective treatments that might be used to minimise death and serious injury.

The framework was developed following a review of literature on Safe System infrastructure and existing risk assessment frameworks. Examples are provided on its application.
