It's easy: 1) Stop building new roads, and stop improving existing ones. Stop worrying about traffic problems; if people don't like it, they can move somewhere else or start using public transit. Maybe 1a) Convert some existing highways to toll roads. Use the funds for #2. 2) Use the money saved by not building or widening roads to build and operate more public transit: buses, and especially trains/subways. Give people a way to commute into the city for work without a car. 3) Fix zoning so that higher-density development is allowed, and can't be stopped by NIMBYs. Require mixed-use development where sensible (i.e., retail shops at ground level). Don't require a certain number of parking spaces, perhaps even add a tax for parking (lower for a garage maybe, higher for open lots). Over time, the area will become denser. People will move closer to the city core, and want to get away from the congestion of the suburbs. This stuff is perfectly doable, but only if there's the political will to do so. This country simple does not have the political will.
