Crude and out-dated traffic modelling is being used to justify massive road building projects across Australia, according to Peter Newman, Professor of Sustainability at Curtin University (InDaily Jan 18th 2015).

Professor Newman says that the huge road projects in Melbourne (East-West Link), Sydney (West Connex), Brisbane (Gateway) and Perth (Freight Link) are “dangerous as they destroy so much of the urban fabric necessary for rejuvenation and take away the ability of governments to pay for the more important urban rail projects on their agendas”.

The same could be argued for Adelaide’s “upgrade” of South Road into a cross-city freeway.
