KT, Seoul Metro team up to keep stations safeKT is rolling out air quality monitors, smart CCTVS and devices that can detect screaming in women’s toilets at subway stations along Seoul Metro’s line No. 5.
The project is part of a research partnership on the future of public transportation that KT and Seoul Metro agreed to last year.
As part of the Green Subway project, which began on Sunday, the companies are introducing an air quality control service, intelligent CCTV and a safety system for women’s toilets. According to the mobile carrier, the two corporations established infrastructure for the project over the last two months in major stations on line No. 5, which runs across Seoul from west to east.
KT’s GiGA IoT Air Map, an air quality monitoring and control system based on Internet of Things technology, was installed in line No. 5’s Gwanghwamun, Wangsimni and Janghanpyeong stations.
The system measures the density of fine dust particles inside and near the subway stations together with other data related to air quality, such as the temperature, humidity and density of carbon dioxide. Based on the real-time measurements, the subway operator can decide when to run air conditioners. Seoul Metro believes the system could contribute to more energy-efficient use of its air conditioners, and it is considering expanding the system to other stations.
KT also installed CCTVs equipped with IoT sensors to three other stations on line No. 5. The CCTV system, dubbed GiGAeyes, can perform basic video analytics. GiGAeyes runs 24 hours a day and can detect how crowded each station is and whether passengers are in danger.
In the women’s bathrooms, KT installed a device called the Safe Mate. The device can detect screaming in the bathroom. When it hears screaming, a light bar installed at the bathroom entrance lights up and sends alerts to subway station employees’ smartphones.
Seoul Metro said Sunday that the device is expected to prove useful, especially late at night when there are not many passengers in the station.
“Using top notch technologies, including big data, we will strive to create a safer and greener environment for those using subways,” said Seoul Metro CEO Kim Tae-ho.
