Annual total emissions from various model years of the mobile sources in Taiwan were estimated in this project to evaluate the effectiveness of different control measures. To improve the accuracy of mobile source emission estimation, besides literature review for the methods applied overseas to calculate mobile source emissions, this project also executed tunnel pollutants monitoring and on-board Portable Emission Measurement System (PEMS) test to compare the differences between emission factors and real emission on road. Appropriate mobile source emission control strategies in the future were evaluated and proposed base on analyzing the outcome of plans executed by EPA in 2008~2009. To accelerate the information transmission between EPA and local EPBs, online graphical user interface database and in-situ check operation provide useful technical assistance for the auditing the result of EPBs mobile source management. The achievements of this project are summarized as follow: Based on the effectiveness/cost, the strategy priorities for mobile source control are to tighten new vehicle emission standards and to regulate the use of old and high emitting vehicles. The other strategies like: routine exhaust emissions inspection and testing program, and low-pollution vehicle promotion measures should be combined to maximize the effectiveness. There are some appropriate proposals as fallow: 1.New diesel vehicle exhaust control strategies: (1) stricter vehicle emission standards(set and proclaim phase 6 emission standard); (2) exhaust control mechanism; (3) anti-idle system. 2.In-use diesel vehicle exhaust control strategies: (1) on-road high emission vehicle check; (2) anti-idle at diesel vehicle parking areas; (3) periodic maintence of exhaust particulate filters; (4) emission classified management system. 3.Fleet management 4.Clean/Green Car: (1) eliminating old and high emitting vehicles; (2) Subsidizing the use of clean/green car; (3) introducing clean buses. The result of vehicle emission factors by PengShan tunnel pollutants monitoring is lower than the outcome of literature survey and Mobile –Taiwan2.0 model. On-board Portable Emission Measurement System, PEMS, was applied to a real car emission test gained similar consequence. Gathering large amount of data in a short-period with various test conditions and presenting the emission status of an in-use vehicle effectively make the advantage of PEMS. The input parameters of 2008 and estimated emission of 2009 for mobile sources in Taiwan had been updated. The interactive website for this system, please refer to http://mobile.epa.gov.tw/epb/index.aspx. To improve air quality, EPA set up the auditing system for the mobile source management achieved by local EPBs in this project and executed the auditing process through this system. 48 LPG car refit factories within 15 counties and cities were surveyed for Green Car purchase subsidization. 300 samples were survied for the satisfaction about the subsidization process of two strike motocycle elimination policy. The general results for subsidiary amount are satisfaction 67%, unsatisfaction 2%；for application process, 54% acceptable, 7% unacceptable. Most people get subsidization information from motorcycle pits(61%), which can be applied to popularize the motorcycle control strategies in the future. For the auditing of dynamometer testing facilities, commissioners of specialists make a resolution which is 8 stations fit A class, 17 stations fit B class, 1 station fit C class in 2009. The comment for this C class station is that: accomplishment of facility behind schedule to fulfill the function of diesel vehicle management. Commissioners suggested that local government should avoid to make audit score in contract to prevent the comtractors focusing on the scores but the test quality.
