# Songdo International Business District — SCD City Research v0.2.3
**Status:** provisional; not yet imported or published · 11 October 2026
**Entity:** operational urban district; parent: Incheon Metropolitan City (IFEZ; Yeonsu-gu)
**Boundary:** Songdo International Business District/operating Songdo service area, not all 53.4 km² of Songdo International City and not all of Incheon Free Economic Zone.
**Provisional result:** 2B — provisional, conditional district-level; Type **16.25**, Autonomy **5.42**.

## Source audit
11 discovered candidate URLs: 8 examined/accepted, 0 examined/rejected, 2 inaccessible, 1 unexamined; 3 publisher families among examined accepted records. The count excludes reprints as separate publisher origins. Open/search snippets are not treated as source examination.

## Key conclusion
Provisional 2B district-level scenario with material connected infrastructure and two candidate intelligent domains (MOB, SAF). Stronger sources are needed for Songdo-only operating coverage and action-choice logs. Waste network is real but faces phased-closure review; the 2026 AI City vision is not in production.

## Exact quantitative methodology
The eight frozen domains each carry weight 0.125. Each qualified operating deployment must have c>=0.60 and g=1. Coverage coefficients: P .15, D .35, N .65, W 1.00. Type = 100×sum_d(0.125×max_i(g_i×c_i×T_i/3)); Autonomy = 100×sum_d(0.125×max_i(g_i×c_i×A_i/3)). Type 2 requires total >=10 and two independently qualified T>=2 domains; Level C requires >=10 and two independently qualified domains with real, independently selected closed-loop A>=2 actions at N/W scope. Display values round half up.

## Technology inventory and admissibility
### TECH-001: Integrated Songdo/IFEZ smart traffic intelligence and signal coordination
- **Domain:** MOB; T=2; A=1; c=.65; g=1; N coverage; status: operating infrastructure; T2 N eligibility provisional.
- **Territory and reach:** Songdo has 165 major intersections, operational ITS infrastructure. Proportion with working AI closed-loop decision support not specified.
- **Authority:** Traffic operators monitor and choose actions; AI-based intersection analytics reported at IFEZ/Incheon level.
- **Included/excluded rationale:** Conditional: could fall to T1/g0 if AI analysis not a material Songdo network. No confirmed A2/independent closed-loop optimization.
- **Supporting original source IDs:** SRC-001;SRC-003;SRC-004;SRC-009
### TECH-002: IFEZ AI CCTV object recognition and safety center
- **Domain:** SAF; T=2; A=1; c=.65; g=1; N coverage; status: operating platform; Songdo-specific footprint uncertain.
- **Territory and reach:** Phase 1 deployed safety and AI CCTV across IFEZ incl. Songdo; city/district in-service fraction unavailable.
- **Authority:** AI video analysis detects anomalies; operators and police decide response.
- **Included/excluded rationale:** T2/G1 conditional on proving substantial actual Songdo coverage; not autonomous policing.
- **Supporting original source IDs:** SRC-001;SRC-002;SRC-003
### TECH-003: Songdo pneumatic waste network sections 2/4
- **Domain:** ENV; T=1; A=0; c=.65; g=1; N coverage; status: operating with significant aging/closure review.
- **Territory and reach:** 3,543 inlets, 19.1 km pipe, 49.5 t/day design capacity across multiple established Songdo sections.
- **Authority:** Preset automatic pneumatic conveyance, human operation/repair.
- **Included/excluded rationale:** N assumes material network within defined operating district; not evidence of AI optimization or C.
- **Supporting original source IDs:** SRC-007
### TECH-004: IFEZ digital service access and online resident requests
- **Domain:** GOV; T=1; A=0; c=.65; g=1; N coverage; status: operating public services.
- **Territory and reach:** Public digital services accessible to Songdo residents; Songdo-specific transaction totals unknown.
- **Authority:** Online forms, inquiries and staff-led case handling.
- **Included/excluded rationale:** N service reach condition; not separately awarded AI-maturity credit.
- **Supporting original source IDs:** SRC-001;SRC-006
### TECH-005: Building AI resource optimization across Songdo
- **Domain:** BLD; T=2; A=1; c=.35; g=0; D coverage; status: reported generally; site-level status/scale unclear.
- **Territory and reach:** ITU summary describes smart buildings but no named asset or share of buildings with AI feedback control.
- **Authority:** Site building management adjusts energy/comfort, mostly conventional controller; human settings.
- **Included/excluded rationale:** g=0: do not infer district-wide AI performance or operating autonomy from broad case-study summary.
- **Supporting original source IDs:** SRC-009;SRC-010
### TECH-006: 2026 proposed autonomous AI City operations centre
- **Domain:** GOV; T=3; A=3; c=.15; g=0; P coverage; status: planned vision / event-pilot only.
- **Territory and reach:** Crowd prediction experiment at 100k+ music festival not continuous operating district service.
- **Authority:** Future goal-directed AI orchestration, no proven operating citywide delegation.
- **Included/excluded rationale:** g=0: future vision, not achieved Type3/D.
- **Supporting original source IDs:** SRC-008
### TECH-007: Songdo autonomous shuttle descriptions
- **Domain:** MOB; T=2; A=2; c=.15; g=0; P coverage; status: operating route unverified.
- **Territory and reach:** ITU generic statement and stock photo do not establish Songdo N/W transit operations.
- **Authority:** Reported shuttle functions, no verified current paid routes, frequency, or rider numbers.
- **Included/excluded rationale:** Exclude until current transport operator records available.
- **Supporting original source IDs:** SRC-009;SRC-010

## Autonomy C/D test
No verified independently selected operational actions in two material service domains. Citywide/model-based advice, AI speech recognition, surveillance flags, rule-based pump or traffic-priority actuations, and local research prototypes are not automatically A2. See `autonomy_operating_test.csv`.

## Geographic and historical exclusions
Songdo International Business District/operating Songdo service area, not all 53.4 km² of Songdo International City and not all of Incheon Free Economic Zone. Operational, trial, announced, discontinued and unverified installations are tracked separately. The 21 descriptive domains do not create additional weighted credit.

## Sensitivity / next-higher classification
If Songdo-specific deployment extent cannot substantiate N for either intelligent Mobility or Safety, the Type 2 two-domain gate fails despite a potentially >10 numeric evidence scenario; downgrade to Type 1 or unknown as warranted. No autonomy Level C: zero independently corroborated A2 domains at district scale.

## Editor checks before publication
- Verify the candidate N/W coverage numerator and denominator for each score-winning deployment; ask operators for current counts, use and operating continuity.
- Obtain independent operational decision/control evidence before Level C consideration.
- Confirm city vs district identity and avoid parent municipality or regional network score inflation.
- Keep this edition provisional and import without duplicate canonical records; publishing requires an explicit Sites-side action.
