Busan Bus, the Nation's First, Uses City Buses to Monitor Air Quality

'Real-Time Mobile Air Quality Map Production'

Installation of Mobile Air Quality Monitoring System

Utilization of Collected Data and Environmental Administrative Services

Busan City has been conducting a pilot operation of the 'Mobile Air Quality Monitoring System' since April 21, installing it on 54 city buses to measure the air quality inside and outside the buses.

The 'Mobile Air Quality Monitoring System' attaches sensors inside and outside city buses to collect real-time data on fine dust, carbon dioxide, volatile organic compounds, nitrogen oxides, odors, and other pollutants in the air, displaying the data on a map to create an air quality map.

Unlike typical air quality monitoring systems that collect data from sensors installed at fixed points, the system installed on city buses can collect data over a wide area while moving.

It can measure fine dust and other pollutants in real time around roads where citizens mainly engage in activities, visualizing and providing basic air quality data across various parts of the city in real time.

Additionally, sensors installed inside the city buses collect air quality data such as fine dust and yellow dust that threaten passengers' health. The collected data is used by Busan City to verify the performance of disinfection filters installed to improve indoor air quality on city buses and serves as a reference for determining filter replacement cycles.

The real-time data on fine dust and other pollutants will be provided through LCD monitors inside buses starting this September, and in the future, it will also be available on the city’s website and mobile apps through public data linkage.

Mayor Park Hyung-jun stated, “To provide a real-time air quality map across Busan, we will gradually expand the air quality monitoring system currently installed on 54 city buses to offer citizens a more comfortable riding environment.”
