This report describes the proposed Strategy for implementation of Assessing Fitness to Drive for consideration by the Austroads Board. It has been developed based on the Implementation Framework endorsed by the Austroads Board in 2021, together with…

This report identifies trends in crash involvement amongst older road users (aged 75+).

This report investigates the origins of the current Unconfined Compressive Strength (UCS) criteria that differentiates modified granular materials from bound materials. Based on the review, a number of changes to the UCS design criteria are…

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…

Older drivers are over represented in serious injury and fatal crash rates based on distance travelled. While their physical frailty is a contributing factor, ageing may also result in unacceptably diminished driving skills for a minority of older…

There is a widespread claim that older drivers are over-represented in crashes, particularly when crash figures are adjusted for distance travelled. There are numerous reasons suggested for this increased risk, including the increased frailty…

The issue of older driver crash responsibility has been explored first, through the analysis of Australian national fatality data, 1996-1999, which contain attributions of responsibility made by coroners, police or by independent data coders.…

Road design plays a major role in road safety, however, has generally not taken the older road user into consideration. There is therefore a need to take effective action to reduce risk levels to older drivers by designing roads that accommodate…

Stage 1 research for Austroads lead to the development of a model licence re-assessment procedure for use in licensing authorities in Australasia. Stage 2 research set out to undertake a pilot trial of the procedure in an Australian jurisdiction and…

This technical report resulted from a study to develop Austroads guidelines on network level assessment and analysis of data on pavement structural condition. This report outlines the benefits of network level assessment of the structural condition,…
