Air quality and environment Management

  • 도로 재비산먼지 관리시스템 logo
  • To provide clean information on the road environment and to provide the public with information on the re-suspended dust measured by mobile measurement vehicles and to provide administrative agencies with efficient road cleaning.
    It is a measurement management system consisting of mobile measurement vehicle, data transmission and storage system. It is an advanced environmental management system that can accurately grasp the concentration of particulate matter less than 10㎛ in road refuse dust in a cycle of 1 second and share the measurement result with the local government.

measuring
substance
A dust having an aerodynamic equivalent particle diameter of 10㎛ or less among the dusts re-scattered by the friction between the tire (wheel) of the vehicle running on the road and the road surface
principle of measurement Road dust resuspended vehicle equipped with a measuring instrument modified to enable sampling , analysis and data storage for the calculation of concentration and emissions of road dust. The concentration of PM10 in road ash dust is quickly measured at 1 second intervals.

  • measuring equipment
    • Measures PM10 concentration in real time every second using light scattering concentration type dust meter
  • Driving a vehehicle
    • Measures the particulate matter generated as the vehicle travels in real time using a two-stage constant velocity aspirator
  • Dust Concentration
    Calculation
    • The difference between the concentration of the resuspended dust measured from the back of the tire and the background dust concentration

Re-suspended dust concentration
= {(Left PM10 concentration + Right PM10 concentration)/2}-Background PM10 concentration
Left PM10 concentration : re-suspended dust concentration generated in left front tire
Right PM10 concentration : re-suspended dust concentration generated in right front tire
Background PM10 concentration : atmosphere dust concentration measured at the roof
