Summary | Since FY1999, Suspended Particulate Matter (SPM) except for the primary particulate from a vehiclefs exhaust pipe has been investigated in order to improve the forecast accuracy of the SPM concentration on roadside. In FY2005, we investigated concentration of SPMs on roadside of the elevated national road and the highway. Emission factors were estimated with whole data accumulated from FY1999. |
