Dongtan proposes to have only green transport movements along its coastline. People will arrive at the coast and leave their cars behind, travelling along the shore as pedestrians, cyclists or on sustainable public transport vehicles. The only vehicles allowed in the city will be powered by electricity or hydrogen. Houses are now selling here to Shanghai middle classes for use when spending weekends away from the city. The Controlling authorities are now backtracking on these commitments and allowing private vehicles onto the site.
