摘要: | 積極發展公共運輸已為解決交通問題的共識,而大眾捷運系統(Mass Rapid Transit,MRT)、輕軌捷運系統(Light Rail Transit,LRT)及公車捷運系統(Bus Rapid Transit,BRT)為近年來國際都市在評選之所謂大容量骨幹捷運系統方案,面臨系統建設成本、營運成本、建設時程、功能與績效、網路效應等多方議論。本研究期能建立完善的評估指標與流程,引導國內各城市評估選擇合適的系統型式,朝向正確的永續發展方向。透過城市案例分析,本研究可歸納出永續營運關鍵因素,包含四項可量化、二項不可量化與一項配套因素,利用這些關鍵因素,並配合相關文獻佐證,建立兩層式評估指標與流程。上層的評估指標為城市特性評估指標,包含人口密度、大眾運輸使用比率與人均GDP等三項城市特性評估指標,並將門檻值分為「立體式MRT」與「平面式LRT與BRT」兩個層級;在立體式MRT方面,其人口密度下限值為6,300人/平方公里,大眾運輸使用比率下限值為12%,人均GDP下限值為820,000新台幣;而在平面式LRT與BRT方面,其人口密度下限值為1,200人/平方公里,大眾運輸使用比率下限值為12%,城市人均GDP下限值為340,000新台幣。至於下層的系統方案評估指標,包含經濟效益評估與財務效益評估兩部分,期能利用所訂之門檻找出能夠永續營運的財務機制,最後利用各項指標建立完整評估流程。本研究並應用建立之指標與流程針對國內城市進行分析,透過城市特性指標分析,得知國內各城市應先改善傳統公車使用狀況,同時以新竹市為案例,透過經濟財務效益評估,建議其最適的系統型式為BRT系統。研究並建議可行性研究中應明確納入替選方案分析的概念,期能合理找到城市發展大眾捷運系統的明確方案。 Rapid Transit system is an important part of public transportation. In general, it can be separated into three different types, namely Mass Rapid Transit (MRT), Light Rail Transit (LRT) and Bus Rapid Transit (BRT). It’s been a crucial issue in comparing capital investment, operating cost, construction period, performance, and network effect of these three alternatives. This study aims to develop evaluation mechanism for selecting an appropriate alternative with regards of operational sustainability. Based on case study, the study recognized four quantified factors, two non-quantified factors, and one enhancement factor as the key criteria for assessment of operation sustainability. With these criteria and the verification by literatures related, the study then proposes a two level evaluation framework. Population density, market share of public transportation, and GDP are the criteria in the upper level while five criteria of economic benefits and three criteria of financial benefits are included in the lower level. In the upper level, the threshold has been obtained for two groups of alternatives, namely “graded MRT” and “ground LRT or BRT.” The minimum values of the “graded MRT” are 6,300 people/km2, 30% and NT$ 820,000, while the minimum values of ”ground LRT or BRT” are 1,200 people/km2, 12% and NT$ 340,000, respectively. Finally this study has proposed an evaluation process that has the two level evaluation framework be included for alternatives analysis. The evaluation process has also been applied for analyzing cities in Taiwan. It is shown from the case studies that most of the cities have to improve the service quality of conventional bus. It is also shown that BRT is the most suitable alternative for Hsinchu city. It is suggested that alternatives analysis should be included in the feasibility study in views of sustainable development of rapid trasnit system. |
