Abstract
The techno-economic analysis is a technique to evaluate a technology's economic performance. It measures a technology's entire significance, enabling analysts to objectively assess benefits and expenses. It is crucial to conduct a techno-economic study of any new technology or product at the research and development stage before commercializing it for use in a significant industrial process. Due to the train control system's rapid growth, studies recommended a new communication control system called communication-based train control system. It improves line capacity and minimizes trackside equipment by safely reducing the separation (headway) between trains operating on the same line. The acceptability and economic viability of a new technology can‟t be demonstrated via implementation or adoption without a comprehensive technical and economic feasibility assessment. Therefore, we were motivated to investigate the techno-economic analysis of adopting CBTC for the Ethio- Djibouti railway line. For this study's techno-economic analysis, we utilized capital expenditure, operating expenditure, and total costs of ownership. We have analyzed the coming five consecutive years of revenue and cost data. We also used one year's signal and control data in the Ethio- Djibouti railway. In this study, using techno-economic analyses including net present value, internal rate of return, and payback period as economic indicators, we assessed the overall economic assessment of CBTC technology adoption. Finally, as the results of the study show, adopting CBTC technology on Ethio- Djibouti Railway allows the organization to increase competitiveness and economic returns. In addition to this, the study suggests that the use of CBTC on the railway can improve the safety of the train and faster train operation performance by increasing the ability of railroad lines, particularly in local and regional markets.
