| 摘要: | 目前國內的輕軌運輸系統仍屬發展建設階段，其技術仍是以借鏡國外技術為主，而其中軌道系統因涉及的層面與技術較為廣泛，在系統規劃過程中須參考相關規範、技術及經驗等因素做為評選的依據，雖然決定軌道型式是系統規劃的其中一個項目，但也是其考量系統選用之重要一環，而國內目前並無評估國內輕軌運輸系統可適用軌道型式之選用建議之研究。因此，本研究以提出輕軌運輸系統軌道型式選用分析原則為目的，就目前國內規範、文獻及已完成淡海輕軌運輸系統之軌道型式(無道碴道床)進行探討，再參考國內、外期刊、文獻及蒐集可適用之輕軌運輸系統如單軌捷運系統(跨坐式單軌系統)、自動導引捷運系統(鋼製軌道路面)及智能軌道快運系統等各類軌道型式相關資料，並藉由本研究所提施工成本、施工時間、減振抗噪效果、技術特性及維修性5項關鍵因子做為各類軌道型式案例之比較基準，再與專家問卷訪談中將其所提出意見逐一彙整，並分析各軌道型式之特性及適用性，期能提供國內後續輕軌運輸系統軌道型式規劃時選用之參考建議。;The domestic light rail transit system currently is still under development, and we mainly take a leaf out of foreign countries’techniques for developing the system in Taiwan. As rail system involves comprehensive aspects and techniques, planning such a system requires reference to related technical specifications, regulations and experiences. Although determining a rail type is just a part of the system planning process, it is still a significant one. However, there are no existing studies on evaluating rail type selection for domestic light rail transit system. Therefore, this study aims at proposing principles of selecting and analyzing rail types of light rail transit system. The study first reviewed technical specifications, regulations and references, and analyzed the rail type of the completed Danhai Light Rail Transit (non-ballast track). Furthermore, the study referred to scholarly journals and papers, and comprehensively collected data of various light rail system types, such as monorail rapid transit (straddle-beam monorail), autmatic guided transit (steel running surface) and advanced rapid transit. Five rail type selecting critical factors, i.e., construction costs, duration, vibration and noise reduction, technical characteristics and maintainability, were identified and used as the criteria for comparing light rail systems of various rail types. The features and applicabilities of various rail types were analyzed, and the findings were integrated with and validated by the opinions obtained from rail system experts’ intervies. We believe the study findings can be used as a reference for planning for rail type selection of light rail transit in the future. |
