台鐵西部幹線城際客運列車系統規劃

Abstract

長久以來,經驗法則以及政策指示一直是台鐵在列車安排以及停站規劃時 的主要依據,由於缺乏一套有效的規劃程序,列車頻繁停站的結果導致城際 長途客運列車的角色逐漸模糊,並使得列車的服務水準降低.因此,本研究 乃針對城際客運列車的安排以及各列車的停站規劃,發展出一套有效率的 啟發式列車規劃求解模式,使日後的列車規劃能夠有所依循.大致上旅客的 日需求型態可分為一般日,週末例假日以及連續假期三種,不同日需求型態 旅客起訖的時間與空間分布特性有極顯著的變化,因此有必要依據不同日 需求型態的旅客特性設定不同的模式目標,再依模式設計的邏輯與程序將 旅客需求轉換成列車供給,做到真正以需求為導向的列車規劃.根據本研究 的列車規劃結果顯示,假日時的運能不足的確是目前台鐵在列車安排上最 棘手的問題,但是即便如此,透過本研究的規劃模式還是能有效的改善目前 長途列車在沿途頻繁停靠的問題.此外,將模式規劃結果與現行列車時刻表 比較,證實本研究的列車規劃模式具有不錯的實用性,對於列車的前期規劃 程序極具參考價值. The empirical rules and administrative orders are the primary ways for Taiwan Railway Administration (T.R.A.) to arrange the trains and their stops. It's not an efficient planning process obviously. As a result, the role of long-haul passenger train is becoming unclear and the associated L.O.S. is degraded with frequent stops. To solve this problem, a heuristic intercity passenger train planning model is developed. In general, travel demand can be classified into three types as weekday, weekend and holiday. The three demand patterns have significant difference. Consequently, there is a need to set models with different goals suitable for the demand patterns. With the model and its planning logic, a demand-oriented train plan can be deviced. Based on the study result, the most serious problem of T.R.A. is capacity shortage during the weekend and holidays. Nonetheless, the frequent stop problem can be solved by the model. Furthermore, comparing the model result with the published timetable shows that this model is realistic and is highly recommended for train planning.
