What's the state of the art urban planning in terms of actually giving people less reason to drive/travel? It seems you need more zoning pods in suburbs where mini city centers (with jobs) can pop up, giving people less reason for long commutes.
Encouraging info from the wiki: The Cincinnati Form-Based Code adopted in 2013 is designed to be applied citywide in an incremental way, neighborhood by neighborhood. The code establishes transect zones and specifies standards for transects, building types, frontage types, walkable neighborhoods, and thoroughfares that can be adapted to each neighborhood.[4][5]
