Utilizing urban facility sensor information in U-City: multi-dimensional scaling approach

Urban facilities are becoming more diverse and complex with urban expansion and population growth. To efficiently utilize the information about intelligent urban facility, sensors to acquire information should be first popularized, and measures to combine and utilize different kinds of information should be studied. This study intends to suggest measures to connect and utilize urban facility sensors for information collection and collected sensor information. To study set a range, the range of ‘Urban facilities’ as spatial range is set based on a review of Special Act on the Safety Control of Public Structures and National Land Planning and Utilization Act. The range of sensors is set according to common classification and the classifications under international agreements. Based on the range set above, information connectivity for urban facilities, individual sensor list for urban facilities and information connectivity for sensors are derived using expert survey and suggested the methods for utilizing the established information of urban facility sensors. The sensor information will help to manage individual urban facilities and also help to respond effectively to disasters and accidents, through information sharing.
