In this reserch, conduct a questionnaire survey targeted people in charge of local government and reserchers in disaster prevention filed is and estimate the priority rank of disaster prevention base considering the time scale.Disaster prevention base settings following this result, road network evaluation targeted at Ishikawa-prefecture is tried and it is suggested that more effective road network strengthen plan is possible. Keywords : Disaster prevention base, Disaster prevention plan, Road network reliability, connectivity
