Fine-dust Reduction Space-separated Bus Stop

OverviewFine-dust Reduction Space-separated Bus Stop

This clean-air bus stop will protect citizens using bus stops from fugitive fine dust generated on the road. The system is configured with an Air-cleaning system, an Intelligent control system, and a Solar power generation system. It had been selected as a performance task of the “Advanced Technology Development Project for Environmental Industry” by the Ministry of Environment, and relative researches have been being conducted for three years, and prototype bus stops are now put up in Bucheon city and Guri city, Gyeonggi-do. In addition, the effectiveness of the system is being driven up through a “Living-Lab” method that combines real-life and research through user apps. As of 2021, the new model with upgraded performances will be commercialized in the shape of the “Modular air-clean bus stop”.


Intelligent features

  • Air-cleaning system:  By forming positive pressure inside the stand by means of discharging purified air from the top through a filter-blower, the air-cleaning system can protect the passengers stopping by the bus stop from fugitive fine dust.
  • Intelligent control system:  It is an intelligent technology that collects data around the stand through environmental sensors such as the fine dust sensor and operates the air-cleaning system in response to the change of the situation in realtime, coming with automatic operation control to adjust blowing speed depending on the fine dust concentration level.
  • Solar power system:  The photovoltaic module is attached to the roof of the stand, designed with a technology implemented to generate self-power supply of an average power generation 3,060W per day, consumed to power up LED monitor and light, industrial PC, and mobile phone wireless charger
  • Space-separation safety fence:  Installed on the front side of the bus stop, it primarily blocks the inflow of dust. Clean air generated from the air cleaning system is to be trapped inside the bus stop taking advantage of positive and differential pressure effects through the safety fence, thereby creating a pleasant environment and enhancing energy efficiency
Living-Lab system

It is a system in which the contents of the bus stop including realtime scenes, task performances, improvement points, and facility information are transmitted through a monitoring group made up of citizens who actually use the bus stop, by which lifelike research and development can be continuously carried out.

Future goals

  • Review of installation of about 100,000 locations nationwide (6,000 in Seoul, 25,000 in Gyeonggi-do, etc.)
  • Expanded distribution to other public places (bus terminals, parking lots, construction sites, etc.)
  • Through patenting in joint with local governments and government-funded organizations, KLES aims to develop a ‘fully open modular bus stop’ and commercialize the product during 2021.
