Infrastructure systems and services (ISS), such as physical and organisational structures, are important for the functioning of communities, cities and regions. Whilst physical or hard infrastructure include roads, electrical networks, telecommunications, water supply and waste management systems, organisational or soft infrastructures enable the delivery of critical services which are essential for the governance, economy and social fabric of places. In Australia, for example, given its large territorial area and low population density, transportation systems and services in particular are crucial for the functioning of its communities and economy. As a result, Australia has an estimated road network of 812,000 kilometres which is used by over 14 million vehicles yearly (Austroads, 2008). Additionally, it supports 72% of approximately 2.3 billion tonnes of freight per year, with 50% being single driver operators (BITRE, 2008). Consequently, the cost of maintenance and rehabilitation for roads are the largest single item of expenditure for many local governments
