This plan uses technological sensors to carry out scientific and technological law enforcement. Through cloud storage of image data, it integrates and strengthens statistical analysis of data, combines image, license plate recognition, and noise data collection and automatically performs data comparison and retrieval, strengthens data management applications, and strengthens mobile pollution sources. Environmental monitoring of hotspots. In order to improve the efficiency of inspection and banning of high-noise vehicles, effectively control high-pollution vehicles in the Taichung City area and deter environmental noise, and at the same time urge vehicle owners to implement vehicle maintenance, so as to effectively reduce the impact of motor vehicles on environmental tranquility and air quality. The original performance period of this plan is from April 15, 2011 to the end of December 2011, and 114 sessions will be held in Taichung City's major noise vehicle complaint hotspots, important intersections, traffic hot spots, areas in special need of tranquility, and locations approved by the Environmental Protection Bureau. Motor vehicle license plate recognition and sound camera technology law enforcement inspection operations, and meet the conditions recognized by the agency as effective sessions. In addition, in order to meet the needs of the agency, this plan completed the first contract change on November 24, 2011, and added 15 mobile sound camera technology law enforcements. Therefore, 129 mobile sound camera technology law enforcements must be completed within the contract performance period. The contract amount is NT$3.209,406 from the original NT$2.92 million after the first contract change. According to the statistics until the end of December 2011, a total of 156 sessions were planned and executed, 130 sessions were recognized by the authorities as valid, and 26 sessions were invalid. A total of 242 vehicles were reported and 442 vehicles were notified to be inspected. Vehicle identification data were provided to the agency for comparison of mobile pollution data For a total of 1,404,518 transactions, the overall progress completion rate is 101%.
