In a mitigation or prevention of disaster affliction to pedestrians during a flood, it is important to consider a preliminary countermeasure such as evacuation plan, facilities reinforcement and other concerns. The authors have proposed the route choice model for pedestrians that consider different road maps for each pedestrian, and an example of simulation during a fire evacuation shows that the pedestrian's cognition of the refuge's position affects the evacuation completion rate. In this paper, we propose the flood evacuation simulation model for a pedestrian which couples the pedestrian simulation with the flood simulation. In a simulation example of flood evacuation, there is a possibility that many counter-flow will occur when avoiding flooded area or searching refugees. Since a pedestrian recognize the condition of roads within their visual range and supposes the integrity of unconfirmed roads by the normalcy bias, the local pedestrians tends to choose inappropriate routes in spite of knowledge of the road map. A real-time cognition of road's condition using the IoT devices and handheld devices improves the evacuation completion rate and mitigates the counter-flow of pedestrians.},
