Title: A system dynamics modelling approach to gravel road maintenance management
Abstract: Most pavement maintenance management systems used in Australia have modules which permit the projection of pavement deterioration. These tend, however, to be simple linear deterioration models modified marginally by condition data. However, pavement maintenance is part of a complex system comprising the road pavement, the environment, diverse users, the maintenance authority and local/state/federal governments. This system has significant feedbacks, making it a suitable field for system dynamics enquiry. This paper discusses the application of a system dynamics based pavement management model, utilising the fruits of recent ARRB research into pavement deterioration and rehabilitation for unsealed roads. The paper demonstrates a user friendly system dynamics modelling tool utilising the ARRB research and presents a case study from Moorabool Shire which analyses the pavement deterioration over time of 530 individual segments of unsealed rural road, prioritising rehabilitation treatments based on user preferences and budget constraints and identifying the consequences of different budgetary approaches. Feedback to the decision makers includes the specific roads likely to deteriorate to clay sub-base over the 20 year time horizon, the number of households served by very rough roads, the number of user complaints and the roughness related accident costs and vehicle operating costs.
