Seoul is facing intensifying heatwaves and a shortage of accessible green space in urban areas. Due to high land use saturation, traditional park development is no longer feasible in many regions.
This project aims to scientifically identify the optimal administrative districts for linear parks by analyzing multiple spatial, demographic, and economic factors.
To recommend areas where linear parks would be most impactful, based on:
- Green space deficiency
- Accessibility (public transportation)
- Local demand (floating and residential population)
- Land availability and cost
- Merged 10+ public datasets (land price, park size, subway/bus stops, population, facility density, etc.)
- Performed spatial joins and normalization (log, z-score)
- Selected final features using correlation, PCA loading, VIF, and variance threshold
- Applied K-Means clustering (k=5) → Selected 10 candidate districts
- Weights derived from Coefficient of Variation × Information Gain
- Aggregated standardized feature values into a single score per district
- Measured interaction (traffic flows) between candidate and central areas
- Applied heuristic rules (distance ≤ 5km, minimum outer area, connected clusters)
- Selected 3 final optimal combinations
| District | Key Characteristics |
|---|---|
| Seokgwan-dong | High residential density, low green space ratio |
| Jongam-dong | High floating population, strong transport links |
| Jegi-dong | Adjacent to river, low land cost |
- Integrated multiple perspectives: urban, environmental, socioeconomic
- Combined quantitative scoring (Q(x)) with spatial logic (INTER) for final decision
- Proposed replicable, data-driven model for green infrastructure expansion
