碩士 === 國立臺灣大學 === 土木工程學研究所 === 99 === Exclusive bus lane could effectively enhance the efficiency of bus operation, and divert the mixed traffic to reduce the rate of accident. While the demand in exclusive bus lane is growing along with urban development, bus lane capacity gradually could not satisfy the demand, and then the insufficient capacity causes the phenomenon of bus queues. It has been recognized that bus rapid transit (BRT) could be one of the alternatives to increase the operation efficiency and service quality of the exclusive bus lane. Exclusive bus lane has been considered as Pre-BRT system. It has the features of low investment cost, short construction period, high operation performance, and flexible service routes. This study aims to develop an analytic model to explore cost and benefits of exclusive bus lane and BRT and their comparative advantages. Taipei Jen-Eye Exclusive Bus Lane has been used as the case study. It is shown that comparatively small benefit could be obtained by transforming the exclusive bus lane into a BRT system. It is mainly due to a short corridor. It is also shown from the sensitivity analysis that there is a threshold for obtaining significant benefits by the transforming the bus lane into BRT. Mathematical model developed and results of numerical case shown in this study can be used for planning guideline of BRT system.
