6.3.2 Police patrol base optimization
As the need for smart security that reflects data analysis using Big Data emerged, Daegu Metropolitan
City, Daegu Police Agency and SK Telecom signed a memorandum of understanding (MOU) to
create a safe society, and jointly promoted research to optimize response efficiency through Daegu
Police data analysis. Through the analysis of the 112 emergency call reports, along with dispatch
and the data population, optimized patrol points were piloted through the correlation between
the report occurrence and the response required time and the report occurrence prediction.
The main examples of pilot operations are elaborated upon in the following paragraphs.
A total of 34 new changes have been made at 18 existing patrol locations by adding patrol points in
keeping with frequent reports in Pyeongri-dong, Seo-gu, and by changing the intermittent reports
to new patrol lines.
The pilot programme, in operation for three months, showed a seven per cent reduction in 112
reports and a 3 per cent reduction in five major crime types.
To further enhance safety services for the establishment of social safety systems, Daegu is looking
to develop and establish a safety 2.0 Tool Kit SW. This would provide a social safety analysis and
prediction service using machine-learning techniques for urban Big Data such as 112 reporting,
floating population, aging of buildings and CCTV. Through data analysis, services such as predicting
urban safety and recommending key monitoring areas and patrol stations can be provided.
6.3.3 Smart disaster response system
Daegu has established a disaster-management system that enables three-dimensional, spatial,
information-based policy guidance, disaster/risk/escape facility management and earthquake/
windstorm/flood damage information management. In addition, a disaster information system was
established to provide information on safe evacuation for inhabitants, real-time disaster information
and customized information for users in general.
