Abstract: This paper advocated using the concept of Smart Rail Transportation (SRT) to describe future vision of "high-efficient, fast & convenient, safe, visual, predictable, ecological, and smart" rail transportation industry as a macro-system together with an organizational framework for SRT. This framework is composed of three parts: A) an Intelligent Ground Infrastructure for SRT(SRT-IGI) plus Smart Trains aiming at "in-depth sensing & perceiving"; B) the Internet of Things (IoT) for SRT acting as a common platform for information exchange and resource sharing and aiming at extensive interconnectivity and interoperability among human beings, computers, and physical objects; and C) the top layer a Human-Computer Amalgamated Intelligent Management, Decision-making, and Commanding (HCA-IMDC) system for SRT aiming at premier intelligent data processing. All these three components with their distributed intelligent processing power make the rail transportation "smart". Technical connotation of the three components was analyzed in details. In view of that no comprehensive work on smart rail transportation from view of Information Technology (IT) has been found so far, the authors wish that this framework could provide a basis for further discussion on this subject and contribute to the leap-forward development for rail transportation in our country.

Key words: Smart Rail Transportation (SRT), intelligent system, digitizing, the Internet of Things (IoT)

摘要： 提倡用“智慧轨道交通”来描述未来的“高效、便捷、安全、可视、可预测、环保和智慧”的现代轨道交通行业和宏观系统的发展远景视图，并提出了一个“智慧轨道交通系统架构”。该架构以“智慧轨道交通智能化地面基础设施”（SRT-IGI）和智慧列车为基础实现更透彻的感知；以“轨道交通全联网”(SRT-IoT)作为信息交换与共享平台实现更广泛的互联互通；以“与人类融合智慧管理、决策与指挥”（HCA-IMDC）应用系统为顶层结构。三部分组成结构及分布其中的“智能化”功能共同实现整个交通行业的“智慧化”。同时分别对三部分的技术内涵作了进一步的探讨。鉴于笔者尚未发现从信息技术（IT）角度全面探讨“智慧轨道交通”的文献，所以希望本框架的提出能够为从信息技术（IT）角度全面研究智慧轨道交通提供参考，进一步推动智慧轨道交通在技术上的跨越式发展，使我国轨道交通以“更透彻的感知、更广泛的互联互通、更深入的智能化处理能力”的雄姿，为国家经济建设发展和人性化地为人民服务。
