The existing train detection systems are diversified, and the cost of related systems are also reduced due to popular production and use. There is a trend to adopt multiple detection systems at a block simultaneously with the intention to improve both the reliability and safety of the overall detection system. However, existing detection logic for multiple train detection systems are facing the difficulty from the trade-off between reliability and safety. For example, the parallel logic on the dual axle counter system from the Taiwan Railway improves the reliability but reduces safety at the same time, resulting in a potential collision of adjacent trains at Jiadong station in 2019. This research aims to develop a comprehensive reliability and safety evaluation platform for multiple train detection systems with practical considerations regarding “simultaneous failures from multiple equipment”, “self-monitoring system”, and “equipment degradation characteristics”. In addition, three innovative detection logics to effectively improve reliability and safety of multiple train detection systems will also be designed and examined on actual routes. The developed platform can be used as a standard reference, and the proposed logics can be applied to railways adopting multiple detection systems.鐵路運輸;列車位置偵測系統;評估平台;可靠度;安全性;Railway Transportation; Train Detection System; Assessment Platform; Reliability; Safety
