| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 88 === Mass rapid transit （MRT） has become one of the major transit system in Taipei City. Due to the reason that it can only offer transportation service along a linear corridor, it’s very important to combine with bus system in order to enlarge its service area. The Bureau of Transportation of Taipei City Government and TRTC jointly designed 50 routes of feeder bus of MRT in Taipei. They are subsidized by TRTC and separately operated by each bus company. Based of experience while planning the routes, the performance evaluation of feeder buses’ operation is quite necessary.
This research takes the 21 feeder bus routes of Tamshui Line as study case. We establish an evaluation model, after the investigation about passenger’s characteristics and collecting the relative data around operation, we practically analyze the performance of each feeder bus route.
In this research, we establish 19 performance evaluation index, adopting Factor Analysis, Cluster Analysis, and Discriminant Analysis to find out the comman factors which notably influence the operation performance, and to realize the difference between each route. According to the analysis, there’re 4 common factors which remarkbly influence feeder buses’ operation performance. Inaddition, based on the 4 common factors we can distribute total routes into 9 clusters. Besides, using the discriminant function we may predict the new route’s performance characteristics in the future.
On the other hand, from the point of cost-and-benefit, we analyze each route’s net benefit separately to bus company, TRTC, and the society. According to the analysis, to bus company there’re 18 routes which can bring positive benefit, and there’re 8 routes suitable to TRTC. Besides, there’re 14 routes which can produce positive benefit to society. In addition, we establish the relationship between benefits and characteristics of feeder bus route, in order to predict the benefit production while some new feeder bus is planned in the future.
