If a fire in a large and complex city cannot be suppressed in time, large-scale life and property damage may occur. This study analyzed the effect of compulsory execution on the dispatch of a fire truck. The assumption was that illegal parking affects roads and makes it challenging for fire trucks to enter, and the effects were analyzed using System Dynamics-GIS model. The network was analyzed according to whether or not illegal parking was performed. After modeling the system dynamics, the network analysis results were input to analyze the dispatch distance of fire trucks before and after the forced disposal. Based on this, the change in damage amount(△D) according to the distance before and after the compulsory execution was derived and expressed as a map on GIS. According to the results, the dispatch distance 28.45% increased when illegal parking cars were present, while the dispatch distance and damage amount 22.15%, 10% decreased when compulsory execution was carried out. The results of this study can serve as a basis for inspiring the performance of compulsory execution and establishing detailed guidelines.
Amid the accelerating rise in temperature worldwide, the number of summer heat patients continues to increase despite the nation's No. 1 rank in terms of ratio of heat shelters per area in Seoul. This study analyzed the effect of shuttle operations using the System Dynamics-GIS model to secure the mobility of cooling shelters for the vulnerable population in Seoul. To input into the System Dynamics model, spatial information consisting of the vulnerable population for each Dong in Seoul, cooling shelter (capacity, location), and DEM data were analyzed in GIS. By designing a stock-flow model based on the spatial input information, the pattern of decrease of the heat wave exposure rate according to the evacuation rate of the vulnerable was analyzed in time series. The scenarios consisted of not operating a shuttle bus (Scenario 0), operating a shuttle bus (Scenario 1), and efficient shuttle distribution with the operation (Scenario 2). The heat wave exposure rates of each scenario were 83.5%, 74%, and 59.58%. The heat wave exposure rate of the vulnerable group due to shuttle operations has decreased by as much as 23.92%, and this study’s results can serve as primary data when establishing policies related to shuttle operations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
