1. **Introduction** Rapid urbanization and motorization have created congestion, pollution, and unsustainable mobility patterns. Transit-Oriented Development (TOD) promotes compact, mixed-use communities centered around high-quality public transport systems. By reducing reliance on private vehicles, TOD fosters [[sustainable]] urban mobility, social equity, and environmental [[resilience]]. 2. **Understanding TOD** TOD integrates land use, urban planning, and transportation to create walkable, transit-accessible neighborhoods. Core principles include: - High-density, mixed-use development near transit hubs. - Pedestrian-friendly streetscapes and cycling infrastructure. - Reduced parking and emphasis on public transport connectivity. 3. **Historical Context** The concept originated in the 1990s in response to suburban sprawl and transit inefficiency. Early examples include Curitiba, Brazil, and Portland, USA, which demonstrated the potential of integrated transit-land use strategies. TOD has since gained global recognition as a framework for [[sustainable]] urban growth. 4. **Theoretical Framework** TOD draws from urban economics, environmental planning, and behavioral science: - **Land Value Capture Theory**: Development near transit increases property value and economic activity. - **[[Sustainable]] Mobility Theory**: Promotes low-carbon transport modes. - **Urban Livability Principles**: Encourages human-centered urban [[form]] with access to services, green spaces, and amenities. 5. **Applications** - **Mixed-Use Development**: Residential, commercial, and recreational spaces within walking distance of transit. - **Mobility Hubs**: Integrated facilities connecting buses, trains, and micro-mobility options. - **Pedestrian and Cycling Networks**: Reduced dependence on private cars. - **Urban [[Regeneration]] Projects**: Revitalization of underutilized areas around transit corridors. 6. **Case Studies** - **Hong Kong MTR**: Integrates high-density housing and commercial spaces directly above metro stations. - **Portland Streetcar, USA**: Promotes infill development and [[sustainable]] mobility. - **Curitiba BRT System, Brazil**: Combines rapid transit with land-use planning to encourage [[sustainable]] urban [[form]]. 7. **Challenges** - High initial investment and policy coordination requirements. - Risk of gentrification and social displacement. - Integration of multiple stakeholders across urban planning, transport, and finance sectors. 8. **Future Directions** Future TOD approaches integrate smart mobility, autonomous transit, and AI-based transport optimization. Cities are increasingly adopting “15-minute city” principles, ensuring essential services and transit are within walking distance. 9. **Conclusion** Transit-Oriented Development is a critical framework for achieving [[sustainable]] urban mobility. By aligning land use and transit planning, TOD reduces environmental impact, improves social inclusivity, and enhances urban livability. **References (APA 7th)** Calthorpe, P.
