Model national guidelines for setting speed limits at high-risk locations.

This report incorporates recent research, best practice examples, and jurisdictional inputs to propose a set of model national speed limit guidelines for setting speed limits at high-risk locations. The model guidelines represent a harm reduction approach to speed limits, an intermediate step towards the Safe System. The model guidelines are intended to apply to different road categories and functions typical to Australia, while incorporating criteria for reduced speed limits based on severe crash risk, such as: * road lengths that are narrow, have a substantial level of roadside hazards, have many intersections or property entrances, are curvilinear or undulating, or have higher than average severe casualty crash rates; and * higher-risk intersections, especially on high-volume outer-urban arterials, where engineering treatments are not feasible. The model guidelines aim to provide consistent speed limits on roads and intersections which have a higher severe crash risk, while minimising multiple speed zones over short distances.
