摘要：This paper presents a quantitative analysis of the level of congestion that might occur on the tsunami evacuation route during the tsunami disaster. This evacuation route was defined using ArcGIS software based on the estimated evacuation distance. The area was extracted in several grids. The selected distance was the shortest one between each center point of the grid to the TES location point. The walking speed during the evacuation was estimated equal to the average walking speed of adults, children, and the oldster. This study found that congestion might occur in several points of the evacuation routes, and the level of service of the route would vary from A to D.
