Transportation corridors are key component of transport infrastructure. Priemus et al (2003) stated that corridors are
considered as “bundles of infrastructure that link two or more urban areas. These can be highways (sometimes via
different routes), rail links (high-speed trains, intercity lines, local trains or trams), separate bus lanes, cycle paths,
canals, short-sea connections and air connections”. Corridors provide a more direct connection between the
movement of people and goods and State-significant economic activity (Carr et al, 2010). The low level transport
corridors provide direct connectivity to activity centres such as, schools, places of work, shops and other amenities
which are used on a daily basis. And these segments experience high pedestrian activities and high congestion levels
and low through travel speeds most of the day. Managing road networks and transport infrastructure is a very
complex exercise. Roads in the Community (1997), states ‘The road system has been managed predominantly for
political purposes during Australia's history’. The main Commonwealth objectives have been to open up rural areas,
provide for the defence of remote areas and achieve national integration through the linking of capital cities.
