Which approach best illustrates sustainable urban development in city planning?

The most illustrative approach is mixed‑use, transit‑oriented development, which combines residential, commercial, and recreational spaces around high‑capacity public transit. This strategy reduces car dependence, lowers emissions, and saves land by building up rather than out. It also encourages local economies and community interaction, making neighborhoods more resilient. For example, a downtown block that houses apartments, shops, a park, and a light‑rail station lets people live, work, and play within walking distance, cutting traffic and boosting local jobs. This integrated model shows how planning can meet social, economic, and environmental goals in one design.
