Road re-suspended dust management
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 and principle of measurement

|---|---|
| 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. |
 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 BG_PM10 concentration : atmosphere dust concentration measured at the roof |
