    Abstract: 都會區由於人口集中且大量私人交通運具穿梭其間,使得交通工具成為都會區主要空氣汙染排放來源。而探討大台北都會區的交通空氣汙染問題需將新北市及台北市整體納入考量較符合實際狀況的範圍。本研究依據陳等人過去所開發用來評估大台北地區交通移動污染源之管理模式,加以擴充改良,建立大台北地區交通污染源評估系統,並驗證模式的合理性與可用性,另外以此模式評估大台北地區捷運系統與模式所建構之路網完整性與合理性。
    本研究結合旅次分析模式及交通空氣污染評估模式兩種模式。旅次分析模式的功用為處理旅次資料並尋求最佳路徑;交通空氣污染評估模式則以系統動態學之因果回饋機制為基礎,整合運具選擇子模式、車流子模式以及交通排放子模式三種子模式,計算並比較交通建設完工及管理策略執行前後,交通空氣污染物排放改變量。
    研究中利用模擬結果與台北市政府相關行政機關公佈之數據資料相比較,經此驗證動作證明模式之模擬結果與現況相符合。另外,模擬捷運松山線、機場線、環狀線等交通建設完工後之評估。在整個旅次數量上機車旅次減少最多,但汽車旅次卻無明顯增減;旅次空間分布上汽車車輛多集中於主要道路、快速道路與高速公路,有效紓緩一般道路車流量。在汙染物排放量上,各汙染物皆有減少的情形,其原因大部分來自於機車排放的減少;汙染物空間分布上減少汙染物排放效果較為明顯的區域為台北市。
    Traffic emission is the main air pollutant source in urban area. Since the sources are close to the pedestrian and people in commercial districts, the citizen’s exposure risk caused by the traffic air pollution source is concerned. Air quality has become one of important indicators of urban life quality. To evaluate the correlation between traffic air pollutants emission and air quality of Taipei metropolitan area, one need to include two administration districts, namely Taipei City and Taipei County. The extended model is more appropriate to reflect the current situation of transportation system and activities in Taipei metropolitan area than before. The model is validated and calibrated to confirm its assessment applications. Moreover, this model assesses the integrity and the rationality of the Taipei country transportation district and road network constructed by model.
    This study includes two models, trip analysis model and traffic emission assessment model. The trip analysis model is to model trips and routes in the metropolitan’s transportation network. The traffic emission assessment model integrates three sub-model by System Dynamics theory, namely the Logit sub-model, traffic flow sub-model and traffic emission sub-model. The models then were used to calculate and to compare the air pollutant emission change before and after the mentioned transportation infrastructures were accomplished.
    In the study, the model was confirmed by the processes of validation and calibration with government published data. Evaluation of transportation construction simulation Songshan MRT lines, airport lines, lines, and after the completion of the ring. The number of trips up to the whole motorcycle trips, but there was no detectable change in car trips. The spatial distribution of automotive vehicles and more focused on the major roads, expressways and highways, to relieve the general road traffic. The total emission of NOx , HC, and CO in Taipei metropolitan area is expected to be reduced because of motorcycle are reduced. The total emission of NOx , HC, and CO is reduced in Xinbei City more than in Taipei City.
