近年來政府積極推動公車動態資訊系統，而公動態資訊系統之設置，可提供公車使用者即時到站資訊等相關功能，對於等車服務品質有顯著之提昇。本研究為瞭解先進公車動態資訊系統引進後，使用者經濟效益之改變，分別採用時間價值與消費者剩餘之相關理論，並針對現階段台北市設置公車動態資訊系統之地點進行實證分析。在理論方面，本研究建立等候時間感受度之理論模式，以分析在有資訊系統提供下，使用者因不確定性與焦慮感之降低，將可相對提昇其服務品質；本文並進一步利用個體運具選擇模式推估其等車時間評價值之改變。此外，本文透過消費者剩餘之衡量方法，結合個體運具選擇模式建立使用者效益估計式，估計資訊系統引進後為使用者所帶來的經濟效益。實證研究結果顯示：(1)乘客對等車時間感受度評價與等車時間價值，在有公車動態資訊系統下都呈現降低的現象，此證明有公車動態資訊系統設置後，確實降低使用者等車之不確定性與焦慮感；(2)在使用者個別效益方面，公車使用者每旅次平均約可感受增加相當於6.19元之經濟效益；在等車時間價值之效益推估方面，則為10.93元；(3)在使用者總效益方面，總計現階段設置公車動態資訊系統每年將可帶來971萬元之使用者效益。 Dynamic bus information system(DBIS) is to provide passengers with immediate information about coming runs on their arrival to bus stations and thus offer obvious service promotion. Therefore, The valuation of DBIS, becomes an important recommendation for governments and bus companies on their policies on public transportation.To acquire beneficial changes for passengers in use of Dynamic bus information syste, the study adopted theories such as for value of time and consumer’s surplus. In the mean time the study performed field surveys aimed at DBIS presently installed in Metro-Taipei.This Study also established the theoretical base for relations of time awaited and experiences of passengers . This theoretical base primarily explains by DBIS, how much and why passengers could reduce their anxiety and uncertainty during bus waiting and analyzes DBIS concrete benefits by co-adoption of Disaggregate mode choice model There are our discoveries after practically researching: (1)obvious reduce of anxiety and uncertainty during bus waiting due to install of DBIS is evidenced by the phenomenon that, under the use of DBIS, the experiential value of waiting is apparently elevated. (2) DBIS increases the consumer's surplus quantified as about $6.19 per time and value of travel time quantified as about $10.93 per time. (3) At present, DBIS applied in Metro-Taipei bus transportation can bring forth benefits about $9.71 million per year. (4) If developed in full scale, DBIS can bring forth 134, 808 million and 4.209 billion separately in short, mid and long term per year. (5)By analyses on cost-and-benefit according to DBIS install short ,mid and long term, the value stays between 5.5 to 30.8 and thus presently informs us than its maintenance expenses.
