Analysis of Shelters Acceptable Range According to Evacuation Speed During Flood Disaster by Severe Rain Storm

Abstract

Due to abnormal climate, the flood disaster is occurred globally as well as domestically. The flood disaster measures have been researched continuously. In spite of the Prevention measures, the weather changes are difficult to predict accurately. So then, the evacuation places are essentially needed. The suitability of acceptable range of the current shelters is researched. This research is also analyzed whether both the ordinary people and elderly are considered when shelters are installed. Network analysis is conducted based on the evacuation speed of each subject. Vulnerable area is extracted as well. As a result, selection and management of the additional shelters are needed because the number and capacity of shelters is lacked in residential area.

A Study on the Evacuation Time Considering Elderly’s Walking Speed Change According to the Gradient in Flood Disaster

“…Furthermore, in the case of evacuating with the elderly or children, the average of actual walking speed after tsunami warning was 1.88km/h(0.52m/s). [8] It's presumed in actual situations, the average of adult's walking speed is slower than usual speed because of a lot of unexpected situations and state of disorder. (1)…”
