The _____ model shows the impact of radial highways on the movement of people and services away from the central city to the outskirts.

• A. Sector model
• B. Peripheral model
• C. Concentric zone model
• D. Multiple nuclei model

Answer: (B)

The peripheral model explains how radial highways shape urban growth by pulling people and activities away from the central city toward the outskirts. As highways connect the core to distant suburbs, new suburban centers and edge cities rise at interchanges, hosting offices, shopping, and entertainment that compete with the CBD. This captures the pattern of movement outward and the spread of services along transport corridors, creating a metropolitan area with multiple suburban hubs rather than one dominant center. The other models focus on rings around the center (concentric), growth in wedges along transportation routes (sector), or multiple centers of activity without the highway-driven outward shift (multiple nuclei).
