No the best and cheapest way would be a better and more wide-spread public transit system. Like a subway.

Not sure what point you're trying to make with that image. It's from a traffic black out in one of the most densely populated areas in the world. Where people have access to pretty much any type of transportation they want anywhere in the city. And yes, that includes walking. Getting around by foot in Manhattan is remarkably easy. If they turned all roads into public transit/taxis only, it would probably be a fantastic system. But people want their cars, even in Manhattan, where driving seems like the worst thing in the world.
