Abstract
As the rapid growth of urbanization, risk of flooding in Asian developing cities has been increasing. Though local agencies have integrated their efforts to develop flood preparedness strategies, deploy early warning systems, and plan for evacuations, the cities are particularly vulnerable. This paper aims at evaluating accessibility to evacuation centers in Asian developing city. Hat Yai city (Thailand) was selected as a case study. In this paper, the accessibility was evaluated by travel time between evacuees houses and evacuation centers. The accessibility time to the public evacuation centers were determined. The sensitivity analysis was performed to investigate the relationship between evacuation demand and total travel time in the network. Finally, traffic conditions on evacuation routes were evaluated.
