BRIEF – 12 July 2010 – In Seoul, Korea, local authorities inspired by the whimsical reminiscences of a univerisity professor, ripped down a freeway and restored a river. See this inspiring documentary narrated by Brad Pitt before it expires in the next nine days.
The result? Traffic disappeared and people flocked to the reopened waterway. Commenting in the documentary Professor Jeffrey Kenworthy of Curtin University’s Sustainability Policy Institute says that in the past traffic was believed to behave like a liquid – if you blocked one of its routes, it would flow elsewhere, instead the thinking these days is that traffic is like a gas. It will expand to fill a given space or contract.
