Development of a sustainable maintenance funding process for DIER Tasmania

ARRB was commissioned by the Department of Infrastructure, Energy and Resources of Tasmania (DIER) to provide input into the development of a sustainable maintenance funding plan. The main outcomes of the project were focussed on giving the Department a mechanism to examine the effect of different budget levels on future performance and road user costs. A number of strategic level analyses were undertaken using HDM-4 and the network results were compared to a number of key performance indicators. These analyses were aimed at quantifying the level of financial investment required to achieve a range of intervention thresholds related to a set of desirable or specified minimum levels of service. Following completion of the analyses and supporting documentation, a number of key findings were presented to the Department, some of which have been incorporated into their submission to Treasury for additional funding to facilitate planning and the development of a sustainable maintenance and rehabilitation program.
