摘要

軌道的等級代表軌道的品質優劣。當軌道品質越好，列車可以行駛的速度越快，且運輸時間成本會減少；但同時為了維持較好的軌道品質，軌道需要的檢修次數和養護標準也會變得較嚴格，維修成本相對較高。為有效分配軌道養護成本與提升服務容量，本研究主要發展一軌道路線等級決策分析系統，同時考量維修與運輸成本的權衡關係，以決定路線等級之配置，協助管理單位更有效利用現有資源提升系統之可靠度與安全性。

The track class and speed for North American railroads are governed by regulations from the Federal Railroad Administration. Better quality of track permits greater operational speeds and lower transportation cost but also requiring greater maintenance expenditure. In this study, we considered this trade-off between maintenance and transportation costs, and developed an optimization framework determining the optimal assignment for track class based upon the characteristics of the track, traffic demand, and maintenance budget. This tool can help railroads maintain tracks at their most appropriate level so as to provide reliable and cost-effective services.
