The document discusses strategies for creating livable cities in the 21st century based on principles of people-oriented planning and design. It advocates shifting the focus from prioritizing vehicles to prioritizing pedestrians by improving walking environments, making streets more accessible and direct, and increasing public spaces where people can safely interact. As an example, it outlines plans to reconstruct Christchurch, New Zealand in a people-focused way after earthquakes by rebuilding at a lower scale with a compact, walkable central business district surrounded by green spaces and mobility networks to activate public life. The goal is to shape cities in a way that invites walking, cycling and spending time outdoors through high-quality urban design.
