A data analysis model was developed to be used to more effectively install crime prevention facilities to reduce the possibility of crime in high crime areas.
It is expected that the crime prevention effect will increase as various crime prevention facilities can be scientifically installed in the daily life of the people. The Integrated Data Analysis Center of the Ministry of Public Administration and Security analyzed satellite image data to develop a model that presents areas requiring installation of security facilities such as security bells, security lights, and CCTVs, and announced that it would be distributed to local governments nationwide from mid-May.
This analysis model identifies the conditions and possibility of crime in the region through public data analysis, and proposes areas where crime prevention facilities need to be installed by combining with satellite image data analysis results. The case of using satellite image data analysis results to install crime prevention facilities in the city center is evaluated for the first time in Korea.
The model development was carried out from October 2022 to April 2023 as samples in Ansan-si and Hwaseong-si, Gyeonggi-do. About 20 types of data were used, including the local resident population and floating population, the number of single-person households, the location of entertainment establishments and the number of crimes by crime type, CCTV density, housing type, and satellite images at night.
In the process of developing the analysis model, similarities between areas where crimes occurred in the region and environmental characteristics such as population, household type, and proximity to entertainment establishments were analyzed and the levels were indexed. Afterwards, through satellite image data analysis of the area, dark areas due to lack of night lighting were extracted to derive areas where crime prevention facility installation is required first.
The Ministry of Public Administration and Security expects that the model developed this time will play a role in presenting decision-making standards based on data, rather than civil complaints from residents or intuitive judgments from public officials in charge, in the process of installing crime prevention facilities in high-crime areas by local governments. . It is expected that the utilization of local governments to increase the safety level of the region will be high, and Ansan City and Hwaseong City, which participated in the development of this model, plan to install actual CCTV and security lights based on the analysis results.
Meanwhile, the Integrated Data Analysis Center plans to standardize and disseminate this model so that local governments across the country can use it easily.
Jeong Seon-yong, head of the Government Innovation Organization Office, said, “As crime prevention facilities that are directly related to public life safety are installed based on scientific data analysis, the crime prevention effect will increase in the future.” We will discover and implement tasks to create a government that works well and is trusted.”
