本研究針對電子票證系統實施對公車乘客服務時間之影響進行評估。研究中首先 分析電子票證設置對於乘客上下車行為之影響因子，其次針對臺北市公車所實施的磁卡式電 子票證系統進行分析，並應用乘客驗票過程之分析模式，評估電子票證系統對公車乘客「驗 票」與「延滯」時間之影響，研究中亦比較分析不同改善方案的效益。經由本研究之調查與 分析結果顯示：現行投幣方式與電子票證之平均驗票時間分別為 0.67 秒及 4.10 秒。在不 同的驗票過程下，電子票證實施後，將使乘客平均之下車時間皆高於原本投幣方式之延滯時 間達 2.6 倍以上。 而就短期而言，「減少驗票機列印次數」與「學生使用通行證」之改善 方案，將可增加電子票證之績效達 30 ％以上；就長期改善驗票機的設計以及引進無接觸式 的電子票證系統，將可增加績效達 90 ％。本研究之分析結果，可作為政府或營運機構在改 進或研訂公車及大眾運輸電子票證系統相關政策與方案之參考。

　　　　　This study aims to assess the effects of bus electronic fare collection system on passenger service time. Characteristics and validation process of bus passenger alighting are analyzed. Field survey is conducted to compare the current practice of cash system and the magnetic ticket and electronic fare collection system tested in Taipei. It is shown that the average validation times for the cash and the electronic fare systems are 0.67 and 4.10 seconds, respectively. It is also indicated that the average alighting times for the electronic system under various conditions are significantly higher. Several improvement alternatives are evaluated. For the short run, reducing the frequency of printing information on the ticket and integrating student pass with the electronic system are preferable and can improve the system efficiency up to 30%. It is also suggested for the long run that contactless fare collection system should be considered to improve the system efficiency up 90%. The results obtained in this research can provide government and transit operators useful information for formulating implementation policy of electronic ticketing system.
