The household population of Daejeon Metropolitan City is decreasing, but the entire population is increasing, so the population density of Daejeon is rising sharply. Therefore it is expected that when a sudden disaster occur, then there may a lot of damage in a short time because of the linkage effect. And, in order to prevent the disasters in advance, they suggested an evaluation index by making and prioritizing the order of urban risk factors suited to regional characteristics at this study. According to the results of ‘The Delphi Analysis’ the preparations of forest fire, industrial accident, scorching heat were excellent(1 or 2 points), and it was ordinary(3points) or poor(4points) against the damages of wind and flood, drought, lightning, traffic jam, building collapse, fire explosion, infectious disease poison caused by environmental pollution. But it was very poor (5points) in case of the earthquake. According to the analysis results of AHP, in case of the Natural misfortune disaster, the preparation for the flood, storm and earthquake damage were important. But in case of the Society misfortune disaster, the provision for the forest fires and the building collapse were very important. They suggested of the Value index and Scorecard of disaster risk factors of Daejeon Metropolitan City at this study. If we use this kind of Value index to the right time and place when making safety program and disaster preparation manual, we will be able to cope with the urban disaster more effectively.
