| Summary: | 碩士 === 淡江大學 === 運輸管理學系 === 89 === 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.
Accompanied with that the authority concerned promoted DBIS with a positive attitude in recent years, the importance of skills valuating the benefits of DBIS has been bouncingly increasing.
In this dissertation introduce you with quantification of imperceptibly benefits of DBIS , which is,actually, hard to be quantified.
To acquire beneficial changes for passengers in use of Dynamic bus information syste, the study adopted theories such as for value of time and customer’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.
