충북안길 — When the Shortest Route Is Not the Safest

Field notes

충북안길 models evacuation as a constrained road-network problem rather than a nearest-shelter lookup. Its documented profiles assign different speeds, maximum distances, flood tolerances, slope limits, and stair constraints to vehicles, pedestrians, older adults, and wheelchair users. For a 2023-07-15 Osong scenario, the page reports a 2.60-kilometre vehicle route but no reachable shelter for older adults or wheelchair users under the stated limits. The project also describes a 500-metre population-grid analysis for locating self-evacuation gaps.
