DISASTER EVACUATION SIMULATION CONSIDERING TRANSMISSION OF FALSE AND FACT-CHECKING INFORMATION BY SOCIAL NETWORKING SERVICE

As social networking services (SNSs) have become widespread in recent years, it has become possible to collect information from and broadcast it to an unspecified number of people with ease. In particular, in the case of disasters, information regarding safety confirmation, damage status, and evacuation sites (shelters) is frequently exchanged. In this study, we design a disaster evacuation simulation that takes account of the exchange of information on shelters, transmission of false information on shelters, and fact-checking information by SNS. Furthermore, we investigate the effect of the transmission of false information and fact-checking information on the disaster evacuation behavior. The simulation results pertaining to the transmission of false information and fact-checking information, suggest that it is very important to thoroughly check the source of the information and spread accurate information, when evacuees voluntarily spread information using SNS.
