The authors have proposed the route choice model of pedestrians that considers pedestrian's individual map recognition: the position of refuges, routes, and the condition of roads. The authors have also developed the pedestrian simulator that can be coupled with a physical simulation such as computational fluid dynamics. In an example of pedestrian simulation during a flood evacuation, a real-time recognition of flooded area using such that Internet of Things devices has possibility to improve the evacuation completion ratio. In this paper, we investigate to what extent the evacuation completion ratio improves when the future prediction of flooding area becomes possible. An example of flood evacuation simulation for pedestrians shows that an evacuation ratio increases and the counter-flow of pedestrians decreases when a pedestrian assumes visually unconfirmed roads to be suffered. The example also shows that a short-term prediction of flooded area by physical simulation using computational fluid dynamics could improve the evacuation completion ratio and reduce the inundation time.}, pages = {1672--1682}, title = {浸水シミュレーション予測による浸水徒歩避難の検討}, volume = {60}, year = {2019} }
