The project has completed remote sensing sites selection of 28 monitoring sites including 21 sites on highway ramps and 7 sites on surface roads. A total of 204,156 vehicles were measured. After screening of invalid data, 166,032 vehicle data were available for analysis. The data validity was 81.4%.A total of 76 garages signed contracts for the operation with at least one station in each city or county.A total of 4,228 high emitters were identified and notified. Among them, 3553 vehicles showed for the tests, the call back rate was 84.03%. Test fees were also paid to the garages.Two seminars were hosted in the project.Central district EPBs were invited twice for coordination meetings. Technology transfer workshops were conducted from December 5 to 7.The non-periodical vehicle inspection regulation draft was revised. The remote sensing operation specification was revised. High emitter notification protocol was revised. The control mechanism for vehicles failed to show for the test was drafted. The non-periodical inspection stations approval and management regulation draft was drafted. The dynamometer test model was drafted and a demonstration was conducted. The remote sensing webpage and public information center have been established to take care of motorists and test stations needs. Outreach materials were printed and delivered to test stations. The project collected relevant domestic and oversea information for references. It is found in this project that most vehicles are within the low emission range. Vehicle emission concentrations increase with vehicle ages and decrease with engine displacement volumes. Linear regression analysis of this year’s remote sensing data found idle test high emitters can be predicted from the remote sensing readings to increase the probability of high emitters notified. Compared to the 2004 remote sensing project, this year’s project exhibited higher pollution reduction results. In addition to high emitters screening, remote sensing can be applied to clean screening that offers incentive to clean cars.
