What was the name of Le Corbusier's 1922 urban plan for a city of 3 million?

Le Corbusier’s 1922 urban plan for a city of three million was called Ville Contemporaine, or Contemporary City.

The proposal was an unrealized utopian plan for a highly ordered modern metropolis. At its centre, Le Corbusier placed a transportation hub surrounded by tall, cruciform skyscrapers intended for offices and affluent residents. These towers stood in large green areas rather than on traditional street walls.

The plan separated pedestrian routes from roads and gave automobiles a central role in urban movement. Farther from the centre, lower residential blocks were arranged in landscaped settings for working-class residents. The result was a city organized by zoning, hierarchy, open space and efficient circulation rather than by the irregular street patterns of older European cities.

Ville Contemporaine is often confused with Plan Voisin, another major Le Corbusier urban proposal, but Plan Voisin was a later scheme for transforming central Paris. Ville Radieuse was also a related but distinct urban concept developed later. The three-million-inhabitant figure belongs specifically to the 1922 Ville Contemporaine proposal.
