臺北市為商業活動發達城市，每逢尖峰時段或假日，經常會有大量人潮、車潮往返於市區內或臺北、新北兩市之間，雖臺北市為臺灣大眾運輸最發達的都市，然機動車輛有其便利性，仍為一般民眾多數之選；因此，機動車輛所排放的廢氣，須加以管制，才能有利於整體空氣品質的提升。 故臺北市政府環境保護局環保稽查大隊(以下簡稱稽查大隊)委託瑩諮科技股份有限公司執行「110年度臺北市加強移動性污染源-機車排放空氣污染物稽查管制計畫」，本計畫執行期程自民國110年1月19日至12月31日止；惟今年度受COVID-19疫情影響，5月15日雙北提升為三級警戒，同月19日因本土疫情持續嚴峻，將第三級防疫警戒範圍擴大至全國，公司行號改採居家分流辦公，參考臺北市環保車辨系統車流測站一般道路平日統計，今年5-6月份平均車流較1-4月份減少23.1%、較去年同期減少17.3%；同時行政院環境保護署110年6月3日函文公告(以下稱環保署)，為顧及防疫期間民眾權益，全國機車發照4月以後延長排氣定檢及複驗期限至12月31日止。 本計畫配合中央及環保署防疫政策，5月中旬後路邊攔檢、雙掛號寄發均暫緩實施，以致進度數量落後，亦間接影響定檢率及回檢率等績效。7月27日中央流行疫情指揮中心調降警戒標準至第二級，依稽查大隊指示恢復攔檢工作，計畫開始積極補足疫情期間所落後之2,745輛次；9月28日與機關完成契約變更，原計畫雙掛號14,000件，扣除已寄發7,322件，所餘6,678件全數轉為平信新增38,380件，調整後平信年度應寄發138,380件，10月再因配合臺北市電動機車加碼補助政策，取消當月寄發之平信，部分郵資由計畫支應，折換後總寄發數為119,759件；同時依據環保署修正公告考評機車污染改善納管率目標【原目標*(1–11.4%)】，原計畫定檢率為83%修正為需達73.5%（含）以上。 統計成果至110年12月31日，茲將本計畫工作成果摘要說明如下： 一、 機車不定期路邊攔檢作業 計畫執行總進度為100%，攔檢15,323輛次中5,138輛屬未定檢車輛，不合格機車數1,517輛次，不合格率為9.9%，與機車定檢資料庫比對後，未定檢及不合格車輛回檢4,973輛次，回檢率為74.7%。 二、 車牌辨識作業 於本市道路共拍攝100,851輛次，車牌取唯一51,284輛次，重複率49.1%，其中設籍本市比例35.6%，設籍外縣市比例為64.4%；設籍本市車較多的行政區為內湖區，而設籍外縣市較多的行政區則為大同區。 三、 催檢通知作業 (一) 平信：針對設籍本市逾期未定檢機車寄發二次通知349,644件，累計回檢率為51.2%，平信通知後回檢車輛約可提升27.1%定檢率（以每6,600輛貢獻1%定檢率計）。 (二) 雙掛號：機車經二次通知後仍未定檢者，則以雙掛號通知限期改善，逾期則依法告發裁罰，相關統計如下： 1、 逾期未定檢：寄發第一次雙掛號催檢通知6,156件，累計回檢率為49.7%；逾期六個月者，依法寄發第二次雙掛號催檢通知，寄發1,166件，累計回檢率44.3%，最終依法註銷車籍69輛。 2、 無定檢紀錄：二行程及四行程(出廠十年以上)完全無定檢紀錄車輛，經第一次雙掛通知後報廢361輛，累計回檢(報廢及已定檢)數量增加約20%。 四、 空維區巡查作業：110年1月1日臺北市公告劃設「第一期空氣品質維護區」共3站6處，稽查30,664輛，巡查告發149輛，區域內機車之定檢率達99.5%。 五、 機車定期檢驗定檢率 依環保署公告12月份設籍本市機車應定檢車輛數為659,028輛，完成定檢輛次為503,612輛，定檢率76.42%。 六、 噪音支援作業 配合稽查大隊於每週三、六早上9：30~11：30、下午13：30~16：00及每週五、六夜間22：00~24：00執行機動車輛噪音稽查業務；因配合防疫措施，5月中旬後暫停夜間噪音攔查，僅維持噪音檢測站定點檢測勤務，8月份恢復正常勤務，截至12月31日共執行121場次。 七、 空氣品質不良支援作業 當空氣品質指標（AQI）有機會大於100或已達100以上時，配合稽查大隊應變出勤進行攔查作業，截至12月31日(含例假日)共執行29場次。

Taipei City’s business activities are abundant. Traffic is very heavy during the rush hour and weekends in Taipei City or between Taipei City and New Taipei City.
