Abstract
Railways around the world are experiencing growth in traffic demand and need to expand their network capacity and increase system reliability. The commuter railway operator in Taiwan, the Taiwan Railways Administration (TRA), is no exception. To accommodate the substantial future demand, increase the reliability of system and reinforce the safety of operation, the TRA is interested in understanding the potential benefit of adopting various advanced signaling systems, such as ERTMS systems. Appropriate evaluation tools are required to understand the cost-effectiveness of adopting these new systems; therefore, in this study, I developed a process of cost-benefit analysis to evaluate the impact from using advanced signaling systems; I also developed a set of analytical capacity models for commuter rail operations with advanced signaling systems. The use of this process and capacity models can help railway agencies with similar operational environments on their capacity management and resource planning. These models were implemented in the busiest corridor in the TRA system. Although the empirical results show that advanced signaling systems generally have positive effects on capacity, delay reduction, safety and environment, the net present value of various scenarios are negative.
