This paper derives the fire risks of buildings in Seoul through the prediction of property damage and occurrence of fires.
This study differs from prior studies in that it utilizes variables that include not only a building's characteristics, but also its affiliated administrative area as well as the accessibility of nearby fire-fighting facilities.
The independent variables used to predict property damage are largely divided into the building's innate characteristics, the characteristics of its affiliated administrative area, and fire-fighting facilities; with the results of the Random Forest algorithm, the RMSE value is around 261, and the accessibility of surrounding fire-fighting facilities was derived as the important predictor variable.
The independent variables used to predict the occurrence of fires are divided into building characteristics, energy use, population characteristics, and characteristics of the building's administrative area; with the results of the random forest algorithm, the accuracy was valued to be around 74%, and the building characteristic was derived as the important predictor variable.
Fire risk prediction was made on 300 buildings in Seoul utilizing the established model, and it has been derived that with buildings at Level 1 for fire risks, there were a high number of households occupying the building, and the buildings had many factors that could contribute to increasing the size of the fire, including the lack of nearby fire-fighting facilities as well as the far location of the 119 Safety Center.
On the other hand, in the case of Level 5 buildings, there were a high number of surrounding buildings and businesses, the highest number of fire-fighting facilities, as well as a nearby 119 Safety Center within its jurisdiction, indicating that these buildings could respond appropriately to fires.
