考量列車路段運轉行為之車站容量模式研發

Abstract

中間站和端末折返站是鐵路路網中常見的兩種車站類型，由於列車之間進出車站時常有路線上之衝突，因此車站通常成為鐵路路網中之容量瓶頸。然而，現有的車站容量研究往往僅考慮車站本身，忽略了列車在路段上運行的影響。本研究分別以中間站和端末折返站作為空間參考點，同時考慮列車於路段上運轉之行為，提出模擬模式來評估車站容量。本研究首先分析了連續兩列車間應有的最小時隔，並將其作為兩個模式的輸入值。模式根據運行條件和最小時隔生成模擬列車，並利用衝突檢查模組調整列車進出順序，最後根據模擬結果計算容量。此模型實際應用於一個高速鐵路系統上，展示其在評估鐵路車站容量的能力。最後，本研究進一步探討影響容量的關鍵因素，對其進行分析與討論。

Intermediate stations and terminal turn-back stations are two common types of stations in railway network. Due to conflicts in train routes when entering and exiting stations, these stations often become capacity bottlenecks in the railway network. However, existing studies on station capacity often focus on the stations themselves, overlooking the impact of train operations on the segments of tracks. In this research, both intermediate stations and terminal turn-back stations are designated as spatial reference points. Simulation models are proposed that take into account train behavior along track segments to evaluate station capacity. This study begins by analyzing the minimum headway required between two consecutive trains, using it as input for the proposed models. The simulation models generate virtual trains based on operational conditions and the minimum time interval. A conflict inspection module is employed to adjust the sequence of train arrivals and departures. Capacity is then calculated based on the simulation results. The effectiveness of these models is demonstrated by applying them to a high-speed railway system, effectively assessing the capacity of railway stations. Finally, this research delves into a discussion of key factors influencing capacity.
