Abstract: The operating status of urban rail transit is analyzed firstly. As of December 31, 2022, about 10 078 km long rail transit lines were operating in 55 cities around China (it would be 10 176 km in 58 cities if ART systems are included). The newlyapproval programs of urban rail transit are summarized. In 2022, the National Development and Reform Commission (NDRC) approved a new round of construction plans for two cities, involving 12 lines of 211.8 km and an investment of about RMB 181.73 billion, and adjustment plans for three cities, involving 7 lines of 99.2 km and an investment increase of about RMB 52.68 billion. All of these lines are metro lines. The technical development of the industry of urban rail transit has characteristics as follows: (1) The relevant policies successively issued by the state emphasize the development of urban rail transit; (2) integration and coordination with urban development and multilevel transportation system are highlighted in planning and development; (3) programs are launched for the innovation and promotion of urban rail transit technologies by Rail Transit Branch of CCES, specially, civil engineering technologies focus on the construction process and method under complex geological conditions, intelligent construction technologies are employed throughout the life cycle of urban rail transit, and more importance is attached to the development and application of operation transformation and lowcarbon technologies, which represents the development directions of technology.
