Tallawarra Lands — Development Option Planning

Tallawarra Lands is a 535 hectare site adjacent to the Tallawarra power station in the Wollongong local government area, south of Sydney. The developers wanted to test options for both internal traffic and traffic entering and exiting the site.

We developed a model extending beyond the immediate site to include the surrounding road network, cut out of the TRACKS software model covering the Wollongong and Shellharbour local government areas’ strategic network. Existing traffic conditions could be modelled well in Dynameq, but the future traffic demand could not be accommodated on the future road network as coded in the strategic model — a finding later confirmed when those TRACKS future networks were integrated into the Sydney Strategic Network on a separate project and found to lack the needed capacity.
