The average improvement rates were 40.7%, 30.4%, and 16.1% in the first, second, and third hour after street washing and street sweeping operations, respectively. Completed 200 sampling and analysis data, the average dust load and silt load was 1.01g/m2 and 0.21g/m2, respectively. Completed road pollution levels survey and pollution levels adjustment of road section 12 times. A total of 26 defects were found for inspections of washing and sweeping operations, which were immediately improved on-site, and were discussed in the monthly work review meeting to reduce the defect rates.
In terms of pollution control of agricultural machinery, an innovative feature of a road pollution control method is established this year.

Furthermore, executed agricultural machinery pollution control practices in 25 farmlands to enhance farmers the concept of environmental pollution improvement.
In terms of road dust pollution by vehicles and road integrity, since the street dust in Pingtung County comes from multiple pollution sources, roads in industrial areas, dredging roads of gravel fields and procession routes of temple fairs as well as the soils after farmland ploughing entrained to the road surface will all affect the road cleanliness in Pingtung County. In order to solve the pollution problem of road environment and vehicle dust as well as the safety of road users, this year set up and held 2 sessions of meeting of "Pingtung County Road Vehicle Dust Reduction Joint Promotion Group," established a group organization and division of rights and responsibilities, and convened industry and relevant units to jointly study and discuss the pollution improvement action measures and the integration of street washing and sweeping operations, optimize road washing and sweeping operations and pollution improvement, and achieve the effect of improving road environment to enhance the road cleanliness. In addition, 2 surveys were carried out for the easily polluted road sections. The corresponding measures, maintenance rights and responsibilities, and labor division were established to solve the dust pollution and road color aberration around the approach road under the Xingaoshu Bridge in Gaoshu Township as well as to solve the problems of mud and water pollution from the sandstone vehicles in the outer ring road of Jiangnan Lane in Ligang Township.
As a whole, 94% of the A-level roads in Pingtung County increased by 2% compared with last year. The public satisfaction questionnaire survey was subcontracted to the Center of Public Opinion and Market Research, College of Social Sciences, National Sun Yat-sen University to carry out the questionnaire of whole county.
