My alternative are things that, unfortunately, would never fly politically:
1) Regulate urban business density in coastal cities and cities more generally limited by water.
2) More multi-core metropolises where the highest <edit: business> density is either spread out entirely, or spread to multiple districts sufficiently far away from each other.
Edit: The comment by hamandcheese showed I had forgotten this important modifier for point 2.
Urban density doesn't cause the issue of traffic. The issue of traffic is caused by cars. Urban density allows public transportation, the only current viable alternative, to be financially sound on a large scale.
Yes lived, parked and drove in downtown NYC for 6 years. 4/5 people parking on the streets own or work in local businesses. Throwing a $350-$450/mo congestion tax their way is bs. They’re keeping the city running with their vehicles, not hurting it.
