What is the Galactic City concept?

• A. A linear city along a river with a single core.
• B. A plain grid city with no edge centers.
• C. A metropolis with a single high-density CBD and no outlying centers.
• D. An edge-city model where suburban centers connect to a central urban core via highways.

Answer: (D)

This concept centers on a metropolis built around multiple edge cities connected by highways to a central urban core. In the Galactic City, suburban centers—offices, shopping, and housing—develop at the outskirts and function as distinct hubs, linked by a network of interstates and beltways. The traditional downtown remains important but is no longer the sole center of activity; people and goods move between edge cities and the core, producing a galaxy-like pattern with satellites connected by roads. That’s why describing an edge-city model where suburban centers connect to a central urban core via highways best captures the Galactic City idea. The other patterns describe a single downtown, a plain grid with no edge centers, or a strictly linear/single-core layout and don’t reflect the dispersed, highway-connected network characteristic of this concept.
