Cross-Country Comparison Matrix
TL;DR
One table to place every team on the road-maintenance spectrum — from Japan/Taiwan (mature, tech-rich) to South Sudan (institution-building). Use it to find shared challenges (your networking fuel) and to position Thailand honestly in the forum. Tech-maturity ratings are approximate, for orientation only.
The matrix
| Country | Lead road agency | Network (approx.) | Key challenges | Tech maturity |
|---|---|---|---|---|
| 🇯🇵 Japan (host) | MLIT + NEXCO + municipalities | ~730k bridges; dense expressways | Aging stock, shrinking workforce, municipal capacity | Very high — SIP, NDT, AI |
| 🇹🇼 Taiwan | Highway Bureau (DGH); NLMA for land/building | ~5,300 km highways; 20k+ total | Seismic resilience, maturing asset mgmt | High |
| 🇹🇭 Thailand | DOH (national) + DRR (rural) | ~52k km national; large rural net | Rural funding, road safety, floods | Medium |
| 🇵🇭 Philippines | DPWH | National + regional | Aging roads, flood-control quality, backlog | Medium |
| 🇱🇰 Sri Lanka | Road Development Authority (RDA) | ~12k km trunk/main; ~4.3k bridges | Funding, post-crisis budgets | Medium (mature structure) |
| 🇱🇦 Laos | MPWT | ~15% paved | Climate damage, weak maintenance funding | Low–Emerging |
| 🇨🇩 DR Congo | Office des Routes / FONER | ~15.8k km priority | ~50% funding gap, weak institutions | Low |
| 🇹🇿 Tanzania | TANROADS + TARURA | ~37k km national | Underfunding, understaffing, climate | Low |
| 🇸🇸 South Sudan | (forming) | ~17k km; ~200 km paved | No maintenance institutions/funding; conflict | Very low / building |

Reading the matrix — insights for the forum
Three things to notice
- Shared challenge = networking gold. Funding and workforce recur everywhere except Japan — name them and the room nods.
- Thailand is a useful “bridge” case — mature enough to discuss systems, constrained enough to relate to the JICA students. Lean into that.
- Japan is the frontier, not the template. The real question every team faces: what’s the right tech for my budget and skills? Framing your talk this way is more persuasive than “we should do what Japan does.”
Accuracy note
Figures are gathered from public sources (2024–2026) and rounded; the “tech maturity” column is a coarse orientation aid, not an official index. Verify before quoting a specific number publicly. Per-country sources are on each team’s dossier (team site, login required) and in Thailand-Forum-Prep.
