Major changes have taken place in urban rail transit standards along with the reform of the national standardization work. Timely establishing and keeping improve a standard system that meets the needs of the urban rail transit industry as well as the speed of development, will create benefits to build an organic system that including various types of standards in urban rail transit area, and improve the quality of standards, strengthen the influence of standards, promote technology innovation, and meet the needs of the urban rail transit industry's continuous, healthy and high-quality development. This paper briefly investigates and analyzes main body of the construction of urban rail transit standard system, summarizes existing urban rail transit standard systems, and analyzes their applicabilitys. Proposes the technical route, working principles, establish goals and main construction content of the urban rail transit standard system, and proposes the application scope and structure of the urban rail transit industry standard system, as well as the suggestions of key research and development areas. It is expected to actively promote China’s urban rail transit standards’ work, leading the development of the industry, promote the construction of a strong transportation country and the construction of smart urban rail, as well as occupying a more important position in the field of international standardizations.
