Yongin City Installs Air Quality Signal Lights at 10 Parks with High Foot Traffic

[Suwon Ilbo=Reporter Park No-hoon] Yongin City announced on the 13th that it has installed air quality signal lights at 10 parks with high foot traffic, including the Gyeong-an Stream walking path in Choin-gu, Seocheon Respier in Giheung-gu, and Pungdeok Stream Starlight Park in Suji-gu.

The installation aims to help citizens easily check fine dust concentration at a glance, encouraging residents to voluntarily refrain from going outside on days with severe fine dust and thereby protecting public health.

The air quality signal lights display blue for good air quality, green for normal, yellow for poor, and red for very poor fine dust concentration. In addition to fine dust concentration, the signals also provide information on ozone levels, temperature, and humidity.

Information displayed on the signal lights is transmitted in real-time from 7 measurement stations operated by the city.

The city has been installing air quality signal lights since 2019, and with the addition of 10 new units this time, the total has reached 60 locations.

A city official stated, "The installation of air quality signal lights allows citizens to easily check fine dust concentration in their living spaces," and added, "We will sequentially increase air quality signal lights so that atmospheric information can be easily understood anywhere."
