一、 Motorcycle control tasks (一) Roadside inspection tasks Roadside inspections were conducted 3,038 times during the fiscal year. Of the motorcycles checked during unscheduled roadside inspections, 2,249 passed inspections, for a passing rate of 74.0%; 289 motorcycles failed to pass, for a failure rate of 26.0%. The owners of the motorcycles that failed to pass were required to make improvements within a certain period of time; warnings were sent to those persons who failed to respond by the given deadline. (二) Roving inspection and ticketing During the fiscal year, roving inspections were performed of 8,564 motorcycles along major roads and at mass transit stations, shopping areas, schools, organizations, and businesses. Of the inspected motorcycles, 6,214 were registered in New Taipei. After subsequent cross-checking with data in the scheduled inspection database, it was found that 2,417 of the motorcycles registered in New Taipei had completed improvements, and the re-checking rate (including scrapping and cancellation of registration) was 38.9%. (三) License plate recognition The project performed license plate recognition a total of 1,007,749 times, including 748,754 times for motorcycles registered in New Taipei; motorcycles registered in New Taipei accounted for 74.3% of all motorcycles whose license plates were recognized. Furthermore, as for unscheduled inspection statistics, of the 1,007,749 times license plate recognition was performed, unscheduled inspections were performed of 140,265 motorcycles, which included 100,457 motorcycles registered in New Taipei. The motorcycles registered in other counties and cities were all recorded on the Environmental Protection Administration's resource sharing website in order to notify the other counties and cities. The 2014 license plate recognition inspection campaign was extended through 2015, and enhanced license plate recognition inspection tasks were performed in administrative districts with high effective rates. (四) Mobile scheduled inspection service This project established one mobile motorcycle exhaust inspection station (station number: FA8) at the start of implementation in order to perform scheduled motorcycle inspections in isolated parts of the city lacking private inspection stations. A total of 579 motorcycles were inspected in 2011, 710 were inspected in 2012, 691 were inspected in 2013, and 787 were inspected in 2014. A total of 1,069 motorcycles that had not received scheduled inspection were inspected by this station in 2015, which was an increase of 35% compared with the 787 motorcycles that had received scheduled inspection during the same period of 2014. Implementation results indicated that since scheduled inspection services where offered in isolated areas starting in 2015, the distribution of promotional products to encourage citizens to complete scheduled inspection ensured that the level of public participation in scheduled inspection was higher than in past years. 二、 Diesel vehicle control tasks (一) Roadside inspection tasks A total of 1,041 vehicles received roadside inspections during the fiscal year; of these 603 vehicles passed, and 438 vehicles failed, for a failure rate of 42.0%. Furthermore, 93 vehicles owned by persons who chose to receive testing using the old method (reflection type) failed to meet standards. (二) Visual exhaust inspection results During the year, total of 4,017 notices to receive inspection based on visual exhaust observation were issued, and the greatest shares of these notices were issued to period II and III vehicles (41% and 27%). Further analysis was subsequently performed of year, vehicle type, and exhaust volume data. (三) License plate recognition During the year, license plate recognition of diesel vehicles was performed 92,110 times. Of these, unique vehicle numbers were obtained 48,317 times. Subtracting non-diesel vehicles left a total of 41,401 vehicles, of which period III vehicles constituted 26.7%, period IV vehicles constituted 26.1%, and period V vehicles constituted 27.6%. (四) Clean air zone inspection and tracking 1. Taipei Harbor: We planned unscheduled inspections at Taipei Harbor, with at least one inspection every week. A total of 105 vehicles have been subjected to unscheduled inspections thus far, of which 43 failed, for a failure rate of 41.0%. Furthermore, analysis of 122,385 sets of license plate recognition data (for dump trucks) yielded 1,890 unique vehicle numbers, and it was found after checking the Environmental Protection Administration's inspection database that 1,017 of these vehicles had no inspection records. After performing further investigation of the reason for such a low inspection rate, it was found that 71% of period IV and V vehicles had not been inspected. We recommend that inspection notices be continued to be issued, and visual inspection of exhaust be performed in order to increase the rate of compliance among dump trucks entering and leaving Taipei Harbor. 2. Yehliu clean air zone: We performed roadside inspection tasks in the Yehliu Scene Area during the second week of each month in coordination with the Northern Clean Air Zone. The goal of this effort was to ensure that more tour buses carrying Chinese tourists obtained a vehicle self-management mark. Furthermore, analysis of license plate recognition data found 44,646 valid vehicle numbers; after subtracting 39,238 non-diesel vehicles and 1,534 vehicles with data anomalies, a total of 3,874 vehicles with valid vehicle numbers remained. An assessment of vehicle exhaust pollution level was then performed on the basis of vehicle period. A comparison of data concerning vehicles entering and leaving the Yehliu clean air zone with large buses and trucks registered in the city (including self-use and business-use vehicles) on the basis of age revealed that the ratio of period I and II vehicles entering and leaving the clean air zone was far lower than expected given the number registered in the city; the ratio of period III vehicles entering and leaving the zone was on a par with what would be expected given the number registered in the city; and the ratio of period IV-V vehicles entering and leaving the zone was higher than what would be expected from the number in the city. (五) Outsourced testing of petroleum products As of September 23, 2016, a total of 1,041 diesel fuel inspections had been performed, and 80 diesel samples were sent for outsourced testing after failing inspection by colorimetry and odor comparison. The results of testing were within the statutory standards in the case of all samples
