| Abstract |
Main streets, as symbolic urban spaces, serve not only as vital transportation corridors but also as everyday cultural and social arenas that
embody a city’s identity. This study investigates strategies for improving the spatial environment of main city streets through the case of
Daejeon’s Jungang-ro, analyzed via the 2024 design competition proposal. The research combines literature reviews on the role and
transformation of main streets with detailed analysis of winning design schemes. Three central design concepts are identified: (1) shifting
from vehicle-oriented to pedestrian- and activity-centered streets, (2) creating shared spaces accommodating multiple modes of mobility and
diverse users, and (3) reinforcing the relationship between street space and adjacent buildings. Based on these principles, the proposed
masterplan integrates road diets, sunken plazas linking ground and underground levels, setbacks for building frontages, and flexible block
restructuring. GIS-based accessibility analysis demonstrates that the plan significantly increases the availability of open space, enhancing
walkability and urban vitality. Implementation strategies emphasize phased development, tactical urbanism for temporary testing, governance
structures involving multiple municipal departments, and broad citizen participation through surveys, workshops, and open forums. Comparative
insights from Paris, Stuttgart, and Seoul reveal that long-term, integrated planning is essential to transforming main streets into vibrant,
sustainable public spaces. The study concludes that spatial improvement of central streets requires not only physical redesign but also
systemic coordination with urban architecture, transportation, and community governance, offering implications for revitalizing declining
downtowns and re-establishing urban identity in contemporary cities. |
