新北市「淡水捷運延伸線輕軌運輸系統」,即淡水捷運延伸至淡海新市鎮之輕軌 捷運系統,此線原先由臺北市政府捷運工程局規劃,後來因淡海新市鎮未完全開 發,興建上無迫切性,故該案被裁定暫以公車接駁方式暫行之為佳。目前為配合 內政部營建署調整淡海新市鎮之建設及帶動當地發展,由交通部高速鐵路工程局 重新推動本計劃。目前淡水捷運延伸線可行性研究報告書已經由行政院核定,原 則同意綠山線及藍海線之路網,並優先推動綠山線。高鐵局刻正辦理綜合規劃複 審與環評複審相關作業。 Problem: 針對「淡海輕軌捷運」可行性評估,首要工作為未來的旅運需求分析與預測,試 說明與研擬如何進行淡海輕軌捷運系統的旅運需求分析步驟與架構,須蒐集、調 查或分析哪些因素與資訊? (架構圖、分析步驟、考慮變數(因素)、資料與調查)
