Transit-Oriented Development (TOD) is an urban planning and design strategy that focuses on creating compact, walkable, mixed-use communities centered around high-quality public transportation systems (e.g., metro stations, light rail stops, bus rapid transit stations).
Key principles and emphases of TOD include:
Integration of land use and transportation: Locating housing, jobs, shops, and services within easy walking or cycling distance (typically a 1/4 to 1/2 mile or 400m to 800m radius) of transit stations. (Matches option d)
Reduced dependency on private vehicles: By providing convenient access to public transport and making walking/cycling attractive, TOD aims to reduce car use, traffic congestion, and parking demand. (Matches option d)
Compact, mixed-use development: Higher density development around transit nodes, with a mix of residential, commercial, retail, and civic uses.
Pedestrian and bicycle-friendly design: High-quality sidewalks, cycle paths, safe crossings, and public spaces that encourage active transportation.
Increased transit ridership: Making public transport more convenient and accessible to more people.
Environmental benefits: Reduced emissions, less land consumption compared to sprawl.
Social equity: Improved access to jobs and services for those without cars.
Let's evaluate the options:
(a) Encouraging sprawling suburban developments: TOD is the opposite; it promotes compact, transit-centered development to counter sprawl.
(b) Disregarding the integration of housing and transportation: TOD is fundamentally about integrating housing (and other land uses) with transportation.
(c) Isolating residential areas from public amenities: TOD aims to mix uses and locate amenities near residential areas and transit.
(d) Integrating housing with public transportation to reduce dependency on private vehicles: This accurately describes a core emphasis of TOD.
Therefore, TOD emphasizes integrating housing (and other land uses) with public transportation to reduce car dependency.
