台灣的軌道運輸產業在近幾年日益受到重視。因此列車舒適性開始受到重視，相關單位也制定了法規要求列車舒適性能，提升軌道運輸品質。本文依照ISO 263 1-1與UIC 513R兩項規範，利用LabVIEW與MATLAB建立舒適度即時量測系統，使用台鐵普悠瑪號於直線段與曲線段試驗，最後將結果與ATP數據進行比對，探究舒適性不佳之原因，評估應用於軌道檢查之可能性。從分析結果得到直線段舒適性優於曲線段，且車速越高則舒適性越差。在舒適性不佳之原因方面，當列車經過道岔或曲線半徑較小之路線會造成舒適性不佳。研究成果在排除道岔及過彎等路段影響後，未來可應用於軌道檢查，有檢查出軌道瑕疵的可行性，但目前尚須提升檢查之準確性及建立系統化程序，使研究結果可以檢查軌道路線品質。

Taiwan's rail transportation industry has received increasing attention in recent years. Therefore, the comfort of trains has begun to be valued, and relevant agencies have also formulated regulations requiring the comfort of trains to improve the quality of rail transportation. This research followed ISO 2631-1 and UIC 513R that are comfort evaluation specifications, applying LabVIEW and MATLAB to build a real-time evaluation system. Also, it used the Puyuma train from Taiwan Railways Administration to test the system. The testing line included straight and curve sections. Finally, we compared the comfort index with the ATP data of the train to find out the reason that caused poor comfort and assessed the feasibility of track inspection. From the testing results, the straight-line comfort index was better than the curve-line comfort index, and the higher the speed of the train, the worse the comfort. The reasons for poor comfort were when the train passes through a turnout or a small curvature route. After excluding the effect of the turnout and the small curvature route, the results could be applied to the track inspection and would be feasible to check out rail defects. Yet currently, we still need to improve the accuracy of inspection and establish a systematic inspection program. Then, the results can check the quality of the rail route.
