Suburbanization transportation changes reflect which assertion?

• A. Increased rail passenger service
• B. Expansion of highway networks and car ownership
• C. The decline of air travel
• D. The growth of urban rail corridors

Answer: (B)

Suburbanization is tied to a car-first transportation system and wide road networks. As people moved to suburbs, policies and development favored automobile travel, leading to the rapid expansion of highways and more cars per household. This combination made it practical to live farther from city centers while commuting to work and accessing amenities, which is exactly what the transportation changes described reflect.

Rail passenger service did not become the defining feature of suburban growth; in many places it declined or remained limited as highway travel gained ground. The growth of urban rail corridors would align more with dense city-centered development rather than the suburban pattern, and air travel, while important for long-distance trips, isn’t the hallmark of domestic suburban expansion.
