Abstract (in Japanese) (See Japanese page) 
(in English) During natural disasters, congestion is observed due to high traffic generation in the disaster affected areas. Recently, careers are trying to provide an electronic bulletin board for a disaster which uses data access system of cellular networks to secure communication method during emergencies. Moreover, in order to operate the bulletin board effectively, a regulation ratio of voice communication and data communication can be operated separately during disasters and emergencies. In this paper, we propose an optimal ratio of regulations that incorporates users' behavior and traffic generation during disasters and emergencies. By using our user-integrated model, it is possible to simulate and evaluate network systems for natural disasters. We show the effectiveness of our model in designing network systems that reduce user-percived congestion in the network and enhance user satisfaction under emergency communication scenarios.
