Abstract

Kim, J.O. and Lee, J.K., 2019. A study on temporary shelter areas using pedestrian networks in coastal cities. In: Lee, J.L.; Yoon, J.-S.; Cho, W.C.; Muin, M., and Lee, J. (eds.), The 3rd International Water Safety Symposium. Journal of Coastal Research, Special Issue No. 91, pp. 421-425. Coconut Creek (Florida), ISSN 0749-0208.This study aims to analyze service area of shelter in order to plan the evacuation route using a pedestrian-level network in coastal cities. We proposed the process of shelter service area demarcation, which is applied various scenarios for flood inundation risk map, considers the characteristics of refugees such as the general public and the elderly. To solve the problem, the coastal flood maps were constructed to take into account the rise in sea level due to climate change. By using the GIS(Geographic Information System), we calculated the slop of the road by adding elevation to the link of pedestrian-level network, applied differently the walking time according to the slope. A case study was conducted to demonstrate the application of the service area for flood emergency shelters of coastal cities in Republic of Korea. The service area of the study, which reflects the elevation, the condition of evacuees, the accessibility and the flood map, was able to arrive at the shelter in a short time avoiding the high risk of flooding.
